CARPENTER 1 I. OVERVIEW/SUMMARY 2 Q1. Please state your name, address and position. 3 A1. My name is Paul R. Carpenter. I am a Principal of The Brattle Group, an economic and 4 management consulting firm with offices in Cambridge, Massachusetts, Washington 5 D.C., San Francisco, California, London, England, and Brussels, Belgium. My office is 6 located at 44 Brattle Street, Cambridge, Massachusetts 02138. 7 Q2. 8 9 Will you briefly describe your educational background and professional qualifications? A2. Yes. I am an economist specializing in the fields of industrial organization, finance and 10 energy and regulatory economics. I received a Ph.D. in Applied Economics and an M.S. 11 in Management from the Massachusetts Institute of Technology, and a B.A. in 12 Economics from Stanford University. I have been involved in research and consulting on 13 the economics and regulation of the natural gas, oil and electric utility industries in North 14 America and abroad for over twenty years. I frequently have testified before federal, state 15 and Canadian regulatory commissions, in federal court and before the U.S. Congress, on 16 issues of pricing, competition and regulatory policy in these industries. Outside of North 17 America, I have advised governments and regulatory bodies on the structure of their 18 natural gas markets and the pricing of gas transmission services. These assignments have 19 included testimony before the U.K. Monopolies and Mergers Commission and the 20 Australian Competition Tribunal, and advice to the governments of, and regulators in, 21 Greece, Ireland, the Netherlands, New Zealand and Australia. 22 I have been extensively involved in the evaluation of the economics and regulation of the 23 natural gas industry in North America. In Canada, I have advised pipeline companies and 24 have previously testified before the National Energy Board (“NEB”) and the Alberta 25 Energy and Utilities Board (“EUB”) on matters relating to pipeline competition and 26 capacity expansion, including the Alliance Pipeline Ltd. certification proceeding. I gave 27 evidence on business risk previously before the NEB in the multi-pipeline cost of capital 1 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 case, on behalf of Foothills Pipe Lines, and in more recent NEB proceedings on behalf of 2 TransCanada PipeLines Limited and Trans Québec and Maritimes Pipeline (“TQM”). I 3 recently provided written evidence on business risk before the Alberta Utilities 4 Commission (“AUC,” successor to the EUB) on behalf of Nova Gas Transmission as part 5 of the AUC’s 2009 Generic Cost of Capital proceeding, and before the Ontario Energy 6 Board (“OEB”) on behalf of Union Gas Limited and Enbridge Gas Distribution Inc. as 7 part of their 2007 rate applications. I provided written evidence on business risk and 8 appeared before the Régie de l’Energie (“the Régie”) on behalf of Gaz Métro as part of 9 its 2008 rate application. Further details of my educational and professional background, 10 as well as a listing of my publications, are provided in my curriculum vitae, which is 11 appended to this evidence as Attachment A. 12 Q3. What assignment were you given in this proceeding? 13 A3. I have been asked by Gaz Métro to provide evidence concerning its business and 14 regulatory risks as they affect the return on equity required by investors in Gaz Métro 15 securities, and to render an opinion as to the adequacy of the current formula return to 16 compensate investors for bearing those risks. In particular, I have been asked to evaluate 17 whether, and the extent to which, there have been changes in the business risk and 18 regulatory environment faced by Gaz Métro that are not captured by Gaz Métro’s current 19 formula return. I have also been asked to provide evidence on the comparability of 20 business risk and allowed returns on capital for Canadian and U.S. local distribution 21 companies (“LDCs”), and to compare Gaz Métro’s business risk with the business risk of 22 the LDCs that make up Dr. Vilbert’s pure play U.S. LDC sub sample. 2 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q4. When do you begin your review of Gaz Métro’s business risks? 2 A4. I evaluate changes in Gaz Métro’s business risks since 1999 and 2004. The Régie has 3 used a formula-based methodology to determine Gaz Métro’s allowed return since 1999.1 4 The formula-based methodology was retained by the Régie when it was set to expire in 5 2004.2 The Régie made minor changes to the formula in 2007.3 It has now been 10 years 6 since the formula was adopted and five years since its first sunset date. In my opinion, it 7 is important for the Régie to conduct a de novo review of Gaz Métro’s business risk and 8 allowed return. Gaz Métro’s business risk has changed significantly during the period 9 that the formula-based methodology has been in place. It is important to evaluate whether 10 the formula-based methodology has adequately accounted for these changes, and this 11 evaluation should consider all changes since 1999. 12 Q5. Could you summarize your conclusions? 13 A5. Yes. • 14 The market environment in which Gaz Métro and other gas utilities operate in 15 North America has changed significantly since 1999, reflecting greater 16 uncertainty in the supply of the gas commodity and greater uncertainty in the 17 extent and timing of the growth in demand. This uncertainty is partly reflected in 18 significantly higher gas commodity price levels and volatility, which has 19 significant implications for the need for, and investment risk of, gas utility 20 infrastructure. • 21 Gaz Métro, in particular, has been exposed to greater business risk due to the high 22 level of market risk in its gas distribution business, in part due to the intense 23 competition it faces from electricity and fuel oil. This high level of market risk is 1 Decision No. D.99-11 dated 10 February 1999 for tariffs effective during October 1998-September 1999. 2 Decision No. D-200-196 dated 24 September 2004 for tariffs effective during October 2004-September 2005. 3 Decision No. D-2007-116 dated 15 October 2007. 3 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 compounded by the fact that Gaz Métro has low penetration in the residential 2 heating market, and serves an unusually large and vulnerable industrial load; by 3 recent changes in the level and volatility of natural gas prices; and by 4 environmental initiatives, which tend to harm the competitiveness of natural gas 5 relative to electricity. Gaz Métro is also exposed to regulatory risk related to its 6 Performance Incentive Mechanism. Incentive regulation creates greater expected 7 short-term variations in earnings than does traditional cost-of-service regulation, 8 particularly where deferral accounts are used to adjust for cost under- or over- 9 recovery. 10 • The market risk to which Gaz Métro is exposed in its distribution business 11 manifests itself in uncertainty over the future utilization of its distribution assets. 12 Because Gaz Métro’s gas distribution assets are sunk investments and cannot be 13 redeployed easily to another use should market conditions change, Gaz Métro’s 14 future income earning capability depends critically on the maximum utilization of 15 its assets. Gaz Métro’s performance incentive mechanism encourages Gaz Métro 16 to improve its productivity and allows for productivity gains to be shared with 17 customers. However, if volumes decline over time, the performance incentive 18 mechanism only provides a partial protection from declining volumes. In this 19 way, Gaz Métro bears some market risk that depends on asset utilization. 20 • Investors need to be compensated for bearing risks that they cannot diversify 21 away. An important part of the overall returns to Gaz Métro’s investors comes 22 from the operation of its performance incentive mechanism. However, this 23 mechanism includes volume risk: the incentive scheme is much less likely to pay 24 out if volumes fall. Volumes are likely to fall when general economic activity as a 25 whole is falling—for example, gas demand from industrial customers is likely to 26 fall when industrial output is falling. The volume risk in the incentive mechanism 27 is therefore a source of systematic risk, and thus contributes to Gaz Métro facing 4 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 increased business risk. The most recent results of the mechanism, at a time when 2 the general economy is performing badly, support this conclusion. • 3 Gaz Métro’s allowed return under the formula is significantly below the returns 4 on equity and total capital allowed by regulators for LDCs in the U.S. These 5 differences in allowed returns cannot be explained by differences in business risk 6 or regulation. In fact, Gaz Métro’s business environment is unique relative to that 7 of other Canadian and U.S. LDCs in at least three respects: (1) natural gas has a 8 significantly lower penetration rate in Québec in Gaz Métro’s service territory 9 than in the service territories of typical LDCs in Canada and the U.S.; (2) Gaz 10 Métro faces significantly stronger competition from electricity than other LDCs in 11 Canada and the U.S.; and (3) Gaz Métro has a large industrial customer load, an 12 industrial customer load that is larger than the LDCs in Dr. Vilbert’s U.S. LDC 13 sample. 14 Q6. How is the rest of your evidence organized? 15 A6. In Section II, I discuss the determinants of business risk and the standards for establishing 16 a fair return. In Section III, I provide evidence that recent changes in natural gas markets 17 have increased the business risk of natural gas infrastructure. In Section IV, I discuss Gaz 18 Métro’s business risk environment, and demonstrate that Gaz Métro’s business risk has 19 increased in ways that are not captured by Gaz Métro’s current formula return. Finally, in 20 Section V, I discuss the relevance of comparisons between allowed returns and business 21 risk of U.S. and Canadian LDCs. I compare Gaz Métro’s business environment to that of 22 other U.S. LDCs, including the LDCs in Dr. Vilbert’s pure play U.S. LDC sub sample. 23 24 II. DETERMINANTS OF BUSINESS ESTABLISHING A FAIR RETURN 25 Q7. What is investment risk and how does it relate to a regulator’s decision to establish 26 RISK AND an appropriate allowed return for a natural gas utility? 5 STANDARDS FOR WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 A7. One of the bedrock principles for establishing a fair return on equity for a regulated 2 utility that has been long recognized by economists, regulators, and the courts in Canada 3 and the U.S. is that a reasonable return should “be comparable with the return available 4 from the application of the capital to other enterprises of like risk.”4 This principle 5 implies that any evaluation of the reasonableness of a particular return should consider 6 the level of risk faced by investors in the enterprise, and how those risks and returns 7 compare with other companies with similar risks. Investment risk for a natural gas utility 8 has been defined to include financial and business risks. Financial risk involves the extent 9 to which debt is employed in the company’s capital structure. Business risk is a 10 somewhat more subjective concept and is more difficult to quantify precisely,5 but it is 11 sometimes categorized to include the supply, demand (or market), competitive, operating 12 and regulatory risks that might be faced by particular utilities.6 Both business and 13 financial risks are accounted for in the methodology employed by Drs. Kolbe and Vilbert 14 to estimate the cost of capital for Gaz Métro. For example, as discussed in their evidence, 15 the “equity betas” which are estimated using the Equity Risk Premium method capture 16 the combination of financial and business risks for the particular sample of publicly 17 traded companies employed. 4 National Energy Board, RH-1-70, p.7-5. See also National Energy Board, RH-2-2004, p. 17, where the NEB stated that a fair or reasonable return on capital should meet three requirements. It should: (1) “be comparable to the return available from the application of the invested capital to other enterprises of like risk (the comparable investment standard)”, (2) “enable the financial integrity of the regulated enterprise to be maintained (the financial integrity standard)”, and (3) “permit incremental capital to be attracted to the enterprise on reasonable terms and conditions (the capital attraction standard).” 5 The NEB has recognized that the assessment of business risk is an inherently qualitative exercise. See National Energy Board, RH-2-1994, p. 24: “The Board has systematically assessed the various risk factors for each of the pipelines but has not found it possible to express, in any quantitative fashion, specific scores or weights to be given to risk factors. The determination of business risk, in our view, must necessarily involve a high degree of judgment, and the analysis is best expressed qualitatively.” See also National Energy Board, RH-1-2008, p. 17. 6 See, for example, National Energy Board, RH-4-2001, p. 13. I understand that in past decisions the Régie has treated regulatory risk as an element separate from business risk. In this evidence I include regulatory risk as a part of business risk conceptually, but I also evaluate its implications separately for Gaz Métro’s return on equity. 6 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q8. 2 3 What kinds of risks matter the most in evaluating a company’s business risk from a cost of capital perspective? A8. The risks that matter the most from an equity investor’s perspective are those that cannot 4 be diversified away through the holding of a broad portfolio of securities. Risks that are 5 hard to diversify are those that are generally correlated with the level of (and changes in) 6 general economic activity. Such risks are referred to as “systematic.” Broadly speaking, 7 systematic risks associated with the gas distribution business include uncertainties in the 8 demand for, and supply of, distribution services that are affected by changes in economic 9 activity, including incomes, prices and governmental policies including environmental 10 concerns. 11 Q9. How does rate regulation affect a company’s business risk? 12 A9. On the one hand, rate regulation reduces a company’s business risk if it provides equity 13 investors some assurance that a fair return on and of capital will be earned over the 14 lifetime of the firm’s assets. On the other hand, regulation may enhance a company’s 15 business risk if investors perceive that there is uncertainty in the future regulatory 16 treatment of the firm’s businesses. That is why regulatory risk is sometimes evaluated as 17 a separate component of business risk. While the equity securities of rate regulated firms 18 are generally perceived as relatively stable, low-risk investments, the greater exposure of 19 such firms to competition from other regulated and unregulated businesses, and 20 alternative fuels, has changed that perception somewhat in recent years, particularly in 21 the energy utility sector. 22 Q10. Is there a time dimension to business risk, and if so, how should one think about it? 23 A10. In prior cost of capital cases in other jurisdictions, distinctions have been drawn between 24 so-called “short-term” and “long-term” business risks. But these labels have actually been 25 used to describe two different types of risk and not just the time dimension. Short-term 26 risk has typically referred to factors that affect the year-to-year earnings of the utility in 27 question. One example, applicable to certain utilities, is variations in weather from year 7 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 to year which increase the variability of earnings, but do not affect the long term expected 2 earnings stream. While one would expect investors to pay more for a stable earnings 3 stream than for a more volatile one with the same long term expected value, it is not a 4 risk on which long term investors would place great importance. Other examples of short- 5 term risk include one time events such as a regulatory cost disallowance that would affect 6 year-on-year earnings, but would not be expected to affect an investor’s long-term 7 estimate of expected earnings. These short-term earnings variability risks may be 8 mitigated through the use of deferral accounts or weather normalization procedures. 9 In contrast, long-term risks refer to more fundamental uncertainties in supply, demand, 10 competition, and regulation. Changes in these factors occur over time and they have the 11 potential to result in a failure to recover the expected return of and on the capital invested 12 in the utility. Despite the label, long-term fundamental risks may be also realized in the 13 short term. Another important aspect of long-term fundamental risk that distinguishes it 14 from short-term variability risk is asymmetry. Under conventional cost of service 15 regulation, the potential for economic loss due to exposure to fundamental risk is not 16 offset by the potential to recover more than the return on and of capital. In my opinion, 17 equity investors give greater weight to these types of fundamental, capital recovery risks 18 in terms of their required return than they do to the short-term earnings variability risk.7 7 The NEB recently concluded that while it is important to “consider both long-term and short-term risks and to weigh them based on the circumstances applicable to the pipeline,” regulators have a more limited ability to respond to long-term risks, and that this tends to make them more important than short-term risks. The NEB stated: On the question of the appropriate weights for short versus long-term risks, the Board is of the view that because of the more limited ability of regulators to respond to the realization of long-term risks, there is a sense, in this aspect, that they are more important than short-term risks. Long-term risks are more structural. Therefore, they denote more fundamental factors and trends in the evolution of the overall risk landscape of a company, while short-term risks tend to be either more cyclical or individual events. See National Energy Board, RH-1-2008, p.46. 8 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q11. Why do you say that equity investors give greater weight to fundamental capital 2 3 recovery risk? A11. When investors buy a share of stock, they are buying a share of a long-term earnings 4 stream. They are not buying only a month, or even a year’s worth of performance. The 5 time horizon of any equity investment is inherently long term. The short-term variability 6 in the earnings of an equity investment is only a small part of the business risk picture. 7 This is particularly important for utility investments that when “sunk” into the ground are 8 difficult to redeploy to other valuable uses should their fundamental risks be realized. 9 Q12. How were changes in business risk under a formula approach to return on equity 10 11 traditionally accounted for by Canadian regulators? A12. Ever since various Canadian regulators began to employ formulas for the determination 12 of allowed ROEs, the practice had been to adjust the deemed equity thickness for 13 perceived changes in business risk. Higher business risk would imply that greater equity 14 thickness would be required. 15 Q13. Is there any assurance in theory or practice that adjustments to deemed equity 16 thickness or to formula returns on equity, based on perceived changes in business 17 risk, will ensure that the allowed return on capital that results will be fair or 18 reasonable? 19 A13. No, there is no such assurance. The primary reason is that assessments of relative 20 business risks between companies, and changes in business risk for a particular company, 21 are inherently subjective exercises. Also, under a formula-based methodology there is no 22 necessary numerical connection between the amount that the deemed equity thickness or 23 formula return on equity has been increased by regulators, or in settlements under NEB 24 or provincial formulas, and the increase in the total return required by investors in the 25 equity securities of the benchmark utility to compensate them for bearing that increased 26 risk. That total required return is best revealed by the measures of risk contained in the 27 methodologies employed by Drs. Kolbe and Vilbert to assess the cost of capital for the 9 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 samples they employ. In a review of the total return results that the formulas such as Gaz 2 Métro’s ROE formula have produced, it cannot be assumed that changes in equity 3 thickness or formula return on equity have adequately accounted for changes in business 4 risk without re-estimating the cost of capital. Moreover, any such review should also 5 consider the underlying reasons for why the business risks may have changed since the 6 formula was established or reviewed. This is particularly true now, when very significant 7 changes have been occurring in the market and infrastructure investment environment in 8 which gas utilities throughout North America operate. 9 In the next two sections, I provide evidence regarding changes in the North American 10 natural gas market that have increased the business risk of natural gas infrastructure, and 11 evaluate changes in Gaz Métro’s business risk. 12 13 III. 14 Q14. Could you describe some of the changes in the natural gas market environment in 15 North America that have occurred since 1999 and their implications for natural gas 16 utility infrastructure investment? 17 A14. MARKET UNCERTAINTY, RISK, AND CHANGES IN THE GAS MARKET ENVIRONMENT Yes. The market environment in which gas utilities operate in North America has 18 changed significantly since 1999 reflecting greater uncertainty in the supply of the gas 19 commodity and greater uncertainty in the extent and timing of growth in demand. This 20 uncertainty is partly reflected in significantly higher gas commodity price levels and 21 volatility. These changes have significant implications for the need for, and investment 22 risk of, gas utility infrastructure. 23 The uncertainty in the timing, location, and magnitude of increases in natural gas demand 24 is in part caused by changes in the economy, as relatively more economic activity is 25 concentrated in businesses which use less energy in general, and less natural gas in 26 particular. This trend can be seen in Figure 1, which shows that the energy intensity of 27 the Canadian economy as a whole has declined by more than 40% since 1990. The 10 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 change in the use of natural gas in Québec’s manufacturing sector is larger: since 1990 2 the intensity of gas use in manufacturing in Québec has declined by around 50%, and by 3 about 20% since 1999.8 Figure 1 Declining Energy Intensity of the Canadian and Quebec Economies 120 Each series relative to 1990 = 100 100 80 60 40 20 0 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 Source: Statistics Canada. Statistics Canada changed its methodology for computing manufacturing value added starting in 2004, so that data for 2004-2007 is not directly comparable to data for earlier years. Canada total energy / GDP Canada natural gas / GDP Canada manufacturing sector natural gas / value added Quebec manufacturing sector natural gas / value added 4 5 These changes have been recognized in Canada by the NEB in its summary of the 6 feedback it received in 2006 during its Energy Futures Project consultation sessions. In 7 its report on these sessions under “Key Messages,” the NEB writes: 8 1. New Energy Paradigm 9 10 11 12 13 There is consensus that the energy system in Canada has transitioned into a new paradigm characterized by tighter energy markets, high and volatile energy prices, high value currency, higher inflationary pressures, ageing infrastructure at all levels, and an uncertain demand response.9 8 1990 is the first year for which the necessary data are available. 9 National Energy Board, Energy Futures Project: Consultation Sessions Feedback, July 2006, p. 2. 11 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Additional gas market uncertainty has also been created by the increased environmental 2 concerns associated with greenhouse gas emissions and their role in long-term climate 3 change. For example, the Government of Québec has instituted a “Green Fund” to 4 support reductions in greenhouse gas emissions. The financing for the Green Fund comes 5 from a duty levied on distributors of hydrocarbon fuels. Gaz Métro’s levy is passed 6 through directly to customers in its rates. The Green Fund has harmed the 7 competitiveness of natural gas relative to electricity in Québec which increases Gaz 8 Métro’s business risk, as I discuss in more detail in Section IV.C. 9 Q15. What is the evidence for changes in natural gas commodity prices and price 10 11 volatility since 1999? A15. Tighter supply/demand balances for natural gas have led to substantially increased prices 12 and price volatility in North America since 1999. To show this phenomenon, in Figure 2 I 13 have plotted the 12-month forward “strip” price of natural gas on the New York 14 Mercantile Exchange (NYMEX) from April 1990 to March 2009. This is a useful index 15 to reference because it reflects the broad market expectation of the level and volatility of 16 future prices in a way that is normalized somewhat for seasonal effects. 12 WRITTEN EVIDENCE OF PAUL R.

As the figure indicates, 4 since 1999 the average forward price tripled to US $5.63 per GJ and the standard 5 deviation of those prices ballooned to US $2.49 per GJ, an eight-fold increase. A similar 6 pattern can be seen for 36-month NYMEX forward prices shown in Figure 3. 13 WRITTEN EVIDENCE OF PAUL R. CARPENTER Figure 3 NYMEX Natural Gas 36-Month Average Future Prices (April 1997 - March 2009) 15.00 Future Price (US$/GJ) 12.00 Up to 1999 1999 - Present 9.00 6.00 3.00 Up to 1999 1999 to Present 36-Month Average Standard Deviation 2.18 5.50 0.09 2.38 4/ 1/ 20 08 4/ 1/ 20 07 4/ 1/ 20 06 4/ 1/ 20 05 4/ 1/ 20 04 4/ 1/ 20 03 4/ 1/ 20 02 4/ 1/ 20 01 4/ 1/ 20 00 4/ 1/ 19 99 4/ 1/ 19 98 4/ 1/ 19 97 0.00 Note: Null prices are omitted to adjust for market inactivity. Source: NYMEX data obtained from Bridge & Bloomberg. 1 2 While these changes in the commodity market pre and post-1999 are dramatic, even those 3 averages mask to some extent the market changes experienced in just the last 16 months. 4 Over this period, 12-month average forward prices have risen from roughly US $7.80 5 (since January 2008) per GJ in January 2008 to US $12.50 per GJ in July 2008, six 6 months later. The 12-month average has recently fallen to roughly US $4.50 per GJ 7 recently, a price level not seen since late 2003. Whether or not these changes in the gas 8 commodity market are permanent or temporary is a subject of debate. One thing that we 9 can have some confidence in, however, is that there will be continued uncertainty in 10 future prices and increased price volatility, which contributes to greater uncertainty in 11 demand growth and use-per-customer risk for gas utilities distributing the commodity. 14 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 These trends in North American natural gas prices stand in stark contrast to Québec 2 electricity prices, which have remained low and stable. I compare natural gas and 3 electricity prices in Québec in Section IV.C. 4 Q16. How have changes in natural gas prices and volatility manifested themselves with 5 6 respect to the WCSB? A16. By 1995, the Western Canadian Sedimentary Basin (the “WCSB”) had entered into a 7 period of rapid growth in productive capacity. At that time, the principal market concern 8 was whether pipelines could be built or expanded rapidly enough to move that supply to 9 eastern markets. Those market conditions persisted from 1995 until about 1999 and 10 during this time the price of gas from the WCSB was “disconnected” from (i.e., lower 11 than and not highly correlated with) the market price of gas from other North American 12 sources. This occurred because growth in WCSB production had outstripped the pipeline 13 capacity available to deliver that gas to the market. Thus, markets like Québec that relied 14 on WCSB production were enjoying a period in which natural gas was very cheap in 15 absolute and relative terms. 16 That era came to an end with the completion of the TransCanada and Foothills/Northern 17 Border expansion projects in 1998 and the construction of the Alliance and Vector 18 systems that went on line in 2000. Instead of too little pipeline capacity out of the WCSB, 19 the market was entering a prolonged period of excess capacity out of the basin.10 At that 20 point, the price of WCSB gas reconnected with the North American market and it has 21 been connected ever since. This change in the relative prices of WCSB gas and the 22 market price of gas from other sources (as represented by the market price at the Henry 23 Hub) is shown in Figure 4. At the same time the WCSB has reconnected with North 24 American markets, the optimism with respect to conventional WCSB supplies has turned 25 to pessimism. There has not been a significant supply response in the WCSB since 2003 10 In the recent NEB TQM proceeding (RH-1-2008), WCSB supply available for pipelines out of the basin was forecast to be roughly 11 Bcf/day in 2009/2010, while total pipeline capacity out of the basin is roughly 14 Bcf/day. 15 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 despite a period of sustained high prices. The WCSB has become a less desirable basin in 2 recent years as production has plateaued and development costs have increased.

But doesn’t the fact that Gaz Métro receives gas supplies from the Dawn hub in 5 6 Ontario mitigate its exposure to WCSB gas prices? A17. Yes, to some extent. However, the NEB found recently in its March 2009 TQM decision 7 that the supply of gas at Dawn is currently sourced primarily from western Canada.11 8 Moreover, the NEB found sourcing additional supplies for Québec and eastern Canada 9 from Dawn in the future will adversely affect the competitiveness of gas in these markets, 10 because it will raise tolls on the Transcanada Mainline. The NEB stated: 11 National Energy Board, RH-1-2008, p.47. 16 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 2 3 4 5 6 7 8 9 10 Today, the supply of gas at Dawn is primarily sourced from western Canada. There was discussion by TQM witnesses regarding growing production areas that could supply Dawn. However, these witnesses explained that growing Dawn supplies will impact tolls on the Mainline for long- haul shippers of gas from the WCSB. Ultimately, the Board agrees with the view that, in these circumstances, the higher tolls would be passed on to the markets that are served off of the TQM system, further impacting the competitiveness of gas in the markets that TQM is serving.12 11 Gaz Métro, like TQM, cannot fully insulate itself from declining supply in the WCSB by 12 accessing gas supply at Dawn. 13 IV. CHANGES IN GAZ MÉTRO’S BUSINESS RISK 14 A. GAZ MÉTRO’S BUSINESS RISK ENVIRONMENT 15 Q18. How would you characterize Gaz Métro’s assets from a business risk perspective? 16 A18. 17 18 residential, commercial and industrial customers. Q19. How does Gaz Métro’s gas distribution business subdivide in terms of customer 19 20 Gaz Métro’s assets are devoted to the provision of traditional gas distribution services to classes? A19. Gaz Métro forecasted in the 2009 rate case that it would serve roughly 169,000 customers 21 in five tariff classes, D1 (general service), DM (modular service), D3 (stable service), D4 22 (stable service for large volumes), and D5 (interruptible service). In terms of customer 23 class, residential customers made up 66% of Gaz Métro’s customers and 5% of its 24 throughput, commercial customers made up 34% of customers and 44% of throughput, 25 and industrial customers made up less than 1% of customers and 51% of throughput. Gaz 26 Métro forecasted total throughput of 5,099 106 m3 for fiscal year 2009, which represented 27 a decrease from the prior year forecast (the fiscal year 2008 estimate) on a comparable 28 weather-normalized basis. This decrease in throughput is attributed primarily to the effect 12 National Energy Board, RH-1-2008, p.47. 17 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 of declining economic activity, increased competition from fuel oil and increased energy 2 efficiency. 3 Q20. How does Gaz Métro earn income on its distribution services? 4 A20. Since 2000, Gaz Métro’s rates have been set using a Performance Incentive Mechanism. 5 Under this mechanism, Gaz Métro’s rates are set prior to the start of each fiscal year by 6 comparing its projected cost of service to a revenue cap. Gaz Métro’s projected cost is 7 computed using traditional cost of service ratemaking principles, with an allowed return 8 on equity set using the Régie-approved formula-based methodology at a deemed equity 9 thickness. Its revenue cap is computed by escalating the prior years’ cap based on the 10 Québec Consumer Price Index (CPI) minus an X-factor, minus a factor relating to past 11 productivity gains that benefited Gaz Métro. There have been a number of changes to the 12 incentive mechanism since its introduction in October 2000, most recently in October 13 2007. The following paragraphs describe the mechanism as it currently operates. 14 The X-factor is currently set at 0.3%. 15 As well as changing from year to year in line with CPI–X, the revenue cap is also 16 adjusted to account for certain exogenous factors, including: the impact of weather; the 17 impact of changes in interest rates on Gaz Métro’s allowed return; a partial adjustment to 18 take out the impact of changes in consumption by small and medium customers; and the 19 impact of changes to income and capital taxes on the cost of service. 20 The volume adjustment for small and medium customers13 works as follows: if the 21 change in actual total consumption between the preceding year and the year before that 22 by these customers is ΔV, the revenue cap is adjusted by (ΔV+0.86%) x 0.9 x –1. Thus, 23 for example, if volume decreased by 5%, the exogenous factor is (–5% + 0.86%) x 0.9 x 24 –1 = +3.73%. Since, in this case, the part of the revenue cap associated with these 13 Those small and medium load customers served continuously since 1999 without intervention by Gaz Métro’s sales team. 18 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 customers will have fallen by 5% as a result of the reduction in volume, and by 0.3% 2 because of the X factor, the overall effect is that the revenue cap falls by 1.57%.14 This is 3 equivalent to Gaz Métro’s revenue cap changing by 10% of the change in volume, 4 together with an X factor of 1.07%15 for these customers. 16 5 If the revenue cap is greater than Gaz Métro’s projected cost of service, then rates are set 6 so that the projected productivity gain (i.e., the difference between the revenue cap and 7 projected cost of service) is shared equally between customers and Gaz Métro. If, 8 however, Gaz Métro’s projected productivity gain would be sufficient to increase the rate 9 of return on capital by more than 3.75%, Gaz Métro’s share is capped at this level and all 10 further projected gains go to customers. 11 The revenue cap is also adjusted so that Gaz Métro’s share of productivity gains in 12 previous years is passed back to customers after a lag: the revenue cap is reduced by an 13 amount equal to the average of Gaz Métro’s share of productivity gains in the preceding 14 five years. 15 If the revenue cap is less than Gaz Métro’s projected cost of service, then rates are set to 16 recover Gaz Métro’s projected cost of service. In this case, the difference between Gaz 17 Métro’s projected cost of service and the revenue cap must be repaid to customers before 18 Gaz Métro can share in productivity gains or overearnings in later years. 19 At the end of each fiscal year, Gaz Métro’s actual productivity gain is compared to its 20 expected productivity gain. If its actual productivity gain is greater than the expected 21 productivity gain, then the resulting overearnings are shared between customers and Gaz 22 Métro (in the form of a contribution to an energy efficiency fund and a reduction in rates 14 If ΔV is –5%, the component of the revenue cap for small and medium customers changes by –5% +3.73% = 1.27%, plus an X factor of 0.3%, or 1.57% in total. 15 1.07% = 0.3% + 0.86% x 0.9. 16 i.e., if volumes are constant the revenue cap falls by 0.77% + 0.3% = 1.07%; if volumes fell by 5%, the revenue cap would fall by (5% x 10%) + 0.77% +0.3% = 1.57%; if volumes rose by 5%, the revenue cap would fall by (–5% x 10%) +0.77% +0.3%= 0.57%. 19 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 in the second subsequent fiscal year). Gaz Métro keeps 25% of the overearnings, and 2 customers receive 75% (again, if the overall cap of 3.75% extra return on capital is 3 reached, customers receive all of the overearnings).17 If the actual productivity gain is 4 positive but less than the expected productivity gain, then Gaz Métro absorbs all of the 5 difference between actual and expected productivity gain. If the actual productivity gain 6 is negative, then customers and Gaz Métro share the deficit equally (with customers’ 7 share in the form of an increase in rates in the subsequent fiscal year). In this case, Gaz 8 Métro must repay customers for their share of the deficit with interest before Gaz Métro 9 can share in productivity gains or overearnings in later years. 10 Gaz Métro’s overall incentive payment (the sum of projected productivity gain plus 11 overearnings) is also adjusted according to Gaz Métro’s performance on a basket of 12 service quality indicators. If it achieves a service quality score of less than 85%, Gaz 13 Métro receives no incentive payment. If it achieves more than 85%, its incentive payment 14 is multiplied by its score. As a result, Gaz Métro can only achieve the full benefit of the 15 incentive scheme if it scores 100% on service quality. 16 There is an additional incentive payment relating to the Global Energy Efficiency 17 Program (GEEP). Performance under GEEP in terms of reduced consumption attracts an 18 incentive payment of up to $4m. The maximum payment would be achieved if 17 The treatment of overearnings and shortfalls relating to transmission and load-balancing services is slightly different from other revenues and costs. In 2007 the incentive scheme was adjusted in respect of these services, with the result that Gaz Métro is no longer to the same extent able to trade off poor performance in other areas of operations with good performance on these services. In respect of operating transactions (selling transmission and load balancing tools like storage which are not required to meet forecast demand), a volume and price project is made at the start of the fiscal year. At year end, the difference between actual price and forecast price is multiplied by the lesser of actual and forecast volume. 25% of the difference (positive or negative) is kept by Gaz Métro, but overearnings are kept irrespective of whether Gaz Métro has hit its incentive cap. The remainder of the difference is treated as any other revenue. Revenue from financial transactions related to these services (transactions such as loans of unused storage space that do not have an impact on the total volume of transmission and load-balancing tools available during a fiscal year) will be forecast at the start of a fiscal year. If actual revenues are lower than projected revenues, then the deficit will be placed in a deferral account and recovered from customers. If actual revenues are greater than projected revenues, then the difference will be shared 25%/75% between Gaz Métro and its customers, irrespective of whether Gaz Métro has reached its incentive cap. 20 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 consumption is reduced by 120m m3 over five years, and if less than this is achieved the 2 incentive is pro-rated. 3 If the performance incentive mechanism expires, Gaz Métro will not receive any 4 payments owing to it as a result of out-turn productivity gains being greater than forecast 5 in the last year. Alternatively, if at the expiry of the mechanism, Gaz Métro has 6 accumulated a debt to customers as a result of its cost of service being above the revenue 7 cap, it will have to pay off half of this debt over the following three years, subject to a 8 cap of 0.75% times the rate base on the total amount repaid. 9 10 Q21. Is Gaz Métro continuing to make capital investments in its distribution business? A21. Yes, Gaz Métro continues to put additional capital at risk for security reasons and to 11 maintain the value of its investment. Gaz Métro proposed capital expenditures of $114 12 million for fiscal year 2009. This includes $40 million in network expansion 13 expenditures, $28 million in deferred charges expenditures (mainly commercial programs 14 and IT development), and $20 million in network improvement expenditures. 15 Q22. What are the principal classes of business risk to which Gaz Métro is exposed? 16 A22. The principal classes of business risk to which Gaz Métro is exposed include market, 17 regulatory, and supply risks. Gaz Métro is exposed to an unusually high level of market 18 risk in its gas distribution business due to the intense competition it faces from electricity 19 and fuel oil. This high level of market risk is compounded by the fact that Gaz Métro has 20 low penetration in the residential heating market, and serves an unusually large industrial 21 load; by recent changes in the level and volatility of natural gas prices; and by 22 environmental initiatives, which tend to harm the competitiveness of natural gas relative 23 to electricity. Gaz Métro is also exposed to regulatory risk related to its Performance 24 Incentive Mechanism. Incentive regulation creates greater expected short-term variations 25 in earnings than does traditional cost-of-service regulation, particularly where deferral 26 accounts are used to adjust for cost under- or over-recovery. I will return to this topic in 27 more detail below. 21 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q23. How does market risk manifest itself in Gaz Métro’s gas distribution business? 2 A23. The market risk to which Gaz Métro is exposed in its distribution business manifests 3 itself in uncertainty over the future utilization of its distribution assets. Because Gaz 4 Métro’s gas distribution assets are sunk investments, and cannot be redeployed easily to 5 another use should market conditions change, Gaz Métro’s future income earning 6 capability depends critically on the maximum utilization of its assets. Gaz Métro’s 7 performance incentive mechanism encourages Gaz Métro to improve its productivity and 8 allows for productivity gains to be shared with customers. However, if volumes decline 9 over time, the performance incentive mechanism only provides a partial protection from 10 declining volumes. In this way, Gaz Métro bears some market risk that depends on asset 11 utilization. 12 Q24. What factors could affect the utilization of Gaz Métro’s distribution assets? 13 A24. Distribution asset utilization is a function of the wholesale and retail price of the gas 14 commodity itself, of the price of competing fuels, of general economic activity in its 15 service area, and of weather deviations from normal forecast conditions. Of these risk 16 factors, the ones most important to equity investors (i.e., those that are systematic) are the 17 level of prices and economic activity. Weather deviations from normal are less important 18 to equity investors because they are not likely to be correlated with the market and hence 19 they are a diversifiable risk. Again, this is because investors themselves can cheaply 20 diversify away risks that are not correlated with movements in the general economy by 21 holding a portfolio of equities, such as broadly-based mutual funds. Moreover, Gaz 22 Métro is compensated for weather deviations via a deferral account that is included in 23 rate base and amortized over a five year period. 22 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q25. Does Gaz Métro face a risk that the utilization of its system will decrease due to the 2 3 unavailability of gas supply? A25. No. However, Gaz Métro does face a form of supply risk. To the extent that gas supply 4 costs rise and become more volatile, the market risk to which Gaz Métro is exposed 5 increases. As the level and volatility of gas supply costs increases, Gaz Métro’s 6 customers will tend to use less gas and Gaz Métro will face more difficulty attracting new 7 customers. This tends to worsen outcomes under Gaz Métro’s incentive mechanism, as I 8 describe in more detail below. 9 10 11 B. Q26. How do these changes in the natural gas commodity price environment translate to 12 13 EFFECTS OF CHANGES IN THE LEVEL AND VOLATILITY OF GAS COMMODITY PRICES ON GAZ MÉTRO’S BUSINESS RISK Gaz Métro and its customers? A26. Ultimately these price level and volatility changes in the wholesale market are reflected 14 in the retail market. To see this, I have plotted Gaz Métro’s total billing rate for several of 15 its tariff classes in Figures 5 through 7. Using Gaz Métro’s rate D1 as an example, Figure 16 5 shows that during the period October 1995 to September 1998 (“Pre-1999”) the total 17 average billing rate was 27 cents/m3 with a standard deviation of 1.1 cents/m3, and that 18 this amount had increased by 14% over the period. During October 1998 to September 19 2004 (“Post-1999”), the total average rate D1 monthly bill was 42 cents/m3 (a 56 percent 20 increase) while the standard deviation of those amounts increased to 7.6 cents/m3. 21 Starting in October 2004 (“Post-2004”), the total average rate D1 monthly bill increased 22 further to 52 cents/m3 (a 94 percent increase over pre-1999 levels) while the standard 23 deviation of those amounts remained high at 4.3 cents/m3. 23 WRITTEN EVIDENCE OF PAUL R.

The analysis above shows Gaz Métro’s rates paid by end users. These rates therefore 5 include the effect of Gaz Métro’s hedging activities. If Gaz Métro had not hedged part of 6 its exposure to commodity price volatility, the volatility in end-consumer rates would 7 have been even greater. 8 Q28. Have the commodity price changes resulted in changes in patterns of gas use? 9 A28. The fundamental changes in the commodity price environment described above have 10 begun to induce changes in customer use of Gaz Métro’s network. This can be seen in 11 decreases in Gaz Métro’s historical and forecast usage per customer. 26 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 The statistics show significant declines in use per customer over time. Gaz Métro has 2 provided me with data on weather normalized average use per customer for several of its 3 tariff classes.18 These data are presented in Figures 8 and 9 below. For example, for tariff 4 class D1 estimated weather normalized average use in 1999 was 13.9 103 m3. By 2004, 5 estimated weather normalized average use declines to 13.3 103m3, a 4.3% decline. The 6 weather normalized average use estimate for 2009 was 11.3 103 m3, a decline of an 7 additional 14.4%.

Do the recent changes in Gaz Métro’s Performance Incentive Mechanism, namely 3 the new exogenous factor meant to account for declining usage, compensate Gaz 4 Métro for these decreases in average normalized usage? 5 A29. No. I describe in Section IV.A. how the performance mechanism adjusts for changes in 6 normalized usage. It only adjusts for part of the change in volumes associated with Gaz 7 Métro’s SML (small and medium load) customers. It does not adjust for changes in 8 industrial load, which are more significant in volume terms. Moreover, the volume 9 adjustment is incorporated with a two year lag. Therefore, the fiscal year 2010 revenue 10 cap will be adjusted for annual variation in 2008 SML customer usage. 28 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q30. Has Gaz Métro continued to invest in its distribution business since 1999? 2 A30. Yes. Gaz Métro continues to make capital investments in its network. As a result, the size 3 of its rate base has grown by about 29% since 1999 (about 9% since 2004).19 In every 4 year since 1999 capital investment has been greater than depreciation of existing 5 investments, indicating that the network continues to expand. This expansion exacerbates 6 the impact of declining per-customer throughput. In Figure 10 I show how the Gaz Métro 7 rate base has increased over time.

A31. Figure 11 below shows the relative cost of natural gas and fuel oil for large firm and 6 interruptible customers (bars lower than 100% indicate that natural gas is more expensive 7 than fuel oil).

Gaz Métro has lost many large industrial 13 customers since 1999, and its large customer load has decreased significantly. Since 2004 14 the decreasing trend was partially offset by the addition of the TransCanada Bécancour 30 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 cogeneration plant in September 2006, but volumes for 2009 are again below 2004 2 volumes.

As discussed above, Gaz Métro’s industrial load was forecasted to be 51% of 6 its total throughput in 2009. 7 Q32. How competitive is natural gas with electricity for home heating in Québec? 8 A32. According to Gaz Métro’s rate cases filed with the Régie, natural gas has been more 9 expensive than electricity for home heating since 2000. Figure 13 compares the relative 10 fuel costs for natural gas and electricity in Québec (and note that natural gas costs are 11 higher than electricity costs when the bars are smaller than 100%). I show, in Figure 23 in 12 Section IV.B.2., the relative market share for natural gas and electricity use for home 13 heating. In Québec, unlike in Ontario or Canada as a whole, electricity dominates natural 14 gas for home heating. 15 Q33. Why is natural gas at a competitive disadvantage to electricity for residential 16 17 customers in Québec? A33. Hydro-Québec’s electricity rates are low because Québec has abundant, inexpensive 18 hydroelectric resources. Currently, Hydro-Québec’s rates are significantly below market 19 value, which offers a subsidy to electricity users relative to users of competing fuels like 31 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 natural gas. The relative value of this subsidy has risen while the formula-based 2 methodology has been in place.

What about the impact of relative price volatility? 5 A34. As I have discussed, due to the volatility of gas commodity costs, Gaz Métro’s rates have 6 been very volatile since 1999. In contrast, electricity prices are relatively stable, changing 7 no more than annually, and only by small amounts. I compare Gaz Métro and Hydro- 8 Québec’s total billing rates for residential customers since 1998 in Figure 14 below. 32 WRITTEN EVIDENCE OF PAUL R.

The “heritage pool” is 165 TWh of electricity priced at 2.79 cents/kWh that is supplied 4 annually by Hydro-Québec Production to Hydro-Québec Distribution for its end use 5 customers. Both the size of the heritage pool and the price of heritage pool power are set 6 by law. 7 Q36. Is the heritage pool adequate to meet the needs of Hydro-Québec’s end use 8 9 customers? A36. No. Hydro-Québec makes some incremental power purchases at market prices to meet 10 the needs of its end use customers. However, these purchases are small relative to the size 11 of the heritage pool. Hydro-Québec stated in its most recent strategic plan: 12 13 In 2005, the heritage pool filled 98% of energy needs, assuring Québec customers of electricity rates that are among 33 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 2 3 4 the lowest in North America. The relative share of the heritage pool in terms of total supplies will gradually decline in the coming years, but will remain above 90% in 2014.20 Q37. 5 6 Will incremental power purchases have the effect of increasing Hydro-Québec’s electricity prices? A37. Yes, but the effect is very small because the amounts spent on higher priced incremental 7 purchases are averaged with a much larger amount of heritage pool power priced at 2.79 8 ¢/kWh. Hydro-Québec recently accepted 15 bids in response to a tender call for wind 9 power resources at an average cost of 10.5¢/kWh.21 If all of the incremental power 10 purchases contemplated in Hydro-Québec’s 2006-2010 Strategic Plan are priced at 11 10.5¢/kWh, the expected incremental supplies will only cause electricity prices to 12 increase by 1.5% or less annually to 2014, as shown in Figure 15 below. 13 It should also be noted that, to date, actual Québec electricity demand has been lower 14 than forecast in Hydro-Québec’s 2006-2010 Strategic Plan. This led to the shutdown of 15 the Bécancour gas-fired power plant on January 1, 2008, and tends to decrease electricity 16 price expectations. Hydro-Québec’s states in its Strategic Plan that “lower-than-expected 17 sales would lower supply costs, and therefore limit projected rate increases.”22 20 Hydro-Québec, Strategic Plan, 2006-2010, Adjusted Version, September 15, 2006, p. 4. 21 “Tender call for 2,000 MW of wind power: Hydro-Québec accepts 15 bids,” Hydro Québec press release, May 5, 2008. 22 Hydro-Québec, Strategic Plan, 2006-2010, Adjusted Version, September 15, 2006, p.52. 34 WRITTEN EVIDENCE OF PAUL R.

The new Green Fund levy on hydrocarbons increases the cost of both natural gas and fuel 4 oil. On an energy equivalent basis, the tax would normally be expected marginally to 5 favour gas over fuel oil, because natural gas is the cleaner fuel. However, the current 6 rates on fuel oil and natural gas are almost identical (the tax is 1.06 ¢/m3 for natural gas 7 and 1.09 ¢/m3 on an energy equivalent basis).23 Furthermore, after adding the Green Fund 8 levy fuel oil is still cheaper than natural gas for industrial customers (see Figure 11 9 above). 23 The rates are so similar because the natural gas tax rate is effectively equal to the emissions from natural gas consumption last year, divided by the estimated volume distributed this year. Since natural gas consumption is declining, the rate is higher than it would be on an emissions-equivalent basis. 35 0.8% 0.7% 1.4% 1.5% 1.4% 1.4% WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 The Green Fund levy will not increase the price of electricity to any significant extent, 2 because almost none of the electricity generated by Hydro-Québec results in greenhouse 3 gas emissions, so Hydro-Québec’s tax bill will be very low. The levy therefore favours 4 electricity over natural gas. 5 Part of the Green Fund is being used to support a program to reduce consumption of fuel 6 oil, and part of this program is aimed at encouraging industrial customers to switch from 7 fuel oil to natural gas (or, for those customers able to burn either fuel, to encourage them 8 to use more gas and less fuel oil). The total amount of support available is relatively 9 small (around $4.5m per year), and I understand that no projects have yet been proposed 10 under the program. The Green Fund levy therefore also increases gas market uncertainty. 11 The Green Fund levy encourages some consumers to switch to gas, but, for the average 12 industrial customers shown in Figure 11, gas is still more expensive than fuel oil. 13 14 D. 15 Q39. How does Gaz Métro’s performance incentive scheme expose Gaz Métro to volume 16 17 EFFECTS OF GAZ MÉTRO’S PERFORMANCE INCENTIVE MECHANISM ON ITS BUSINESS RISK risk? A39. A major source of business risk comes from the fact that Gaz Métro’s performance 18 incentive scheme gives a poor match between costs and revenues when volumes change. 19 Gaz Métro’s revenue cap is a cap on average revenue per unit of gas distributed, because 20 it is derived from the rates in the preceding year, less the X factor, multiplied by forecast 21 volumes distributed. If volumes distributed fall, Gaz Métro’s revenue cap also falls. The 22 reduction in revenue cap is not completely proportional to the fall in volumes because 23 there is partial protection for changes in small and medium load consumption. However, I 24 estimate that only about 30% to 40%24 of total volumes distributed are covered by the 24 Assuming that the number of customers covered by the exogenous volume factor has not changed since 2007. 36 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 volume change exogenous factor. Thus, in respect of more than half of volumes, Gaz 2 Métro is exposed to volume risk. 3 While Gaz Métro’s revenue cap is linked to volumes, most of its costs are fixed. As 4 volumes change over time, therefore, there is highly likely to be a mismatch between 5 costs—mostly fixed—and the revenue cap, which is mostly proportional to volume. 6 If consumption falls, and particularly if consumption by industrial customers falls, Gaz 7 Métro’s revenue cap falls, but its costs will not fall to the same extent. It would as a result 8 be much more difficult for Gaz Métro to out-perform its revenue cap and earn incentive 9 payments. 10 The results of the mechanism support this analysis: in 2008 the forecast productivity 11 gains exceeded the X factor by about $9.6M, whereas in 2009 the forecast gains were 12 only $3.6M above the X factor. 2008 rate case volumes were approximately the same as 13 2007 rate case volumes (an increase of 0.4%), whereas 2009 rate case volumes were 11% 14 below 2008 volumes. 2010 volumes are expected to be lower still.25 Gaz Metro’s 15 marketing forecast for 2010 volumes is about 400 million m3 below the equivalent 2009 16 marketing forecast. Most of the reduction is ascribed by Gaz Métro to the economic 17 downturn, the competitiveness of fuel oil and energy efficiency. Due to major 18 investments Gaz Métro must make in its aging gas network and the decrease in volumes 19 not compensated by the volume change exogenous factor, Gaz Métro expects that there 20 will be little or no productivity gains for 2010. 21 Q40. Why doesn’t the exogenous volume factor protect Gaz Métro from volume risk? 22 A40. First, most of Gaz Métro’s volumes are not covered by the exogenous volume factor at 23 all: the exogenous factor only covers volumes distributed to small and medium load 24 customers that have been supplied since 1999 without intervention by Gaz Métro’s sales 25 Volumes for the 2010 rate case are not yet available. 37 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 team. As of August 1st 2006, that group included 126,235 customers.26 Assuming that no 2 customers have left this group and that the proportion of medium customers included is 3 the same as the proportion of the small customers that are included, I estimate that this 4 group accounts for 30%–40% of volumes. Thus, Gaz Métro is exposed to volume risk 5 with respect to 60%–70%% of volumes.27 6 Second, the exogenous volume factor only partially decouples revenues from volumes: 7 Gaz Métro is still exposed to 10% of the volume risk. For the D1 customer class (which 8 accounts for the majority of the customers and the volumes covered by the exogenous 9 volume factor), Gaz Métro estimates that approximately 96% of its costs to distribute gas 10 to these customers are fixed. 11 Third, Gaz Métro has to pay for the exogenous volume factor. In respect of volumes not 12 covered, Gaz Métro has to achieve productivity improvements of 0.3% per year in order 13 to “stand still”—the revenue cap falls by this amount each year due to the X factor. In 14 respect of the volumes that are covered by the exogenous factor, Gaz Métro has to 15 achieve productivity improvements of 1.07% per year in order to stand still.28 26 “Performance Incentive Mechanism Agreed in Negotiated Settlement Process (NSP) R-3599-2006,” [Translation – Not approved by Participants], April 19, 2007, p. 15, line 29. 27 Gaz Metro is not fully exposed to changes in these volumes because some customers have made volume commitments. However, these commitments do not fully protect Gaz Metro, as shown by the reduced productivity gains in 2009 and 2010 and the reduced volumes in the 2009 rate case. 28 If volumes do not change from year to year, the exogenous volume factor falls by 0.86% x 0.9 = 0.77%. The revenue cap additionally falls by the X factor of 0.3%, so overall productivity must improve by 0.77% + 0.3% = 1.07% in order to stand still if volumes are constant. 38 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q41. How does exposure to volume risk give rise to increased business risk? 2 A41. Investors need to be compensated for bearing risks that they cannot diversify away. An 3 important part of overall returns to Gaz Métro’s investors comes from the operation of its 4 performance incentive mechanism. However, this mechanism includes volume risk: the 5 incentive scheme is much less likely to pay out if volumes fall. Volumes are likely to fall 6 when general economic activity as a whole is falling—for example, gas demand from 7 industrial customers is likely to fall when industrial output is falling. The volume risk in 8 the incentive mechanism is therefore a source of systematic risk, and therefore 9 contributes to Gaz Métro facing increased business risk. Again, the most recent results of 10 the mechanism, at a time when the general economy is performing badly, support this 11 conclusion. 12 13 V. 14 Q42. Have you compared Gaz Métro’s allowed return under the current, formula-based 15 16 GAZ MÉTRO’S BUSINESS RISK COMPARED TO OTHER GAS UTILITIES IN CANADA AND THE UNITED STATES methodology with allowed returns of other companies of comparable risk? A42. Yes. I have compared Gaz Métro’s allowed ROE and total return under the current 17 formula to those of U.S. LDCs. I find that since the formula-based methodology was 18 adopted, Gaz Métro’s allowed ROE and total return have been significantly lower than 19 those granted to U.S. LDCs. I find that this difference in allowed returns cannot be 20 justified based on differences in regulatory treatment or business risk. Indeed, I find that 21 Gaz Métro’s long-term risk tends to be greater than that of typical LDCs in Canada and 22 the U.S. due to Gaz Métro’s unique business environment. 23 Dr. Vilbert relies in part on market returns for a sub sample of U.S. LDCs to estimate the 24 cost of capital for Gaz Métro. I show that the companies in Dr. Vilbert’s sub sample are 25 of lower risk than Gaz Métro. Dr. Kolbe concludes, based in part on my evidence, that 26 Gaz Métro’s ATWACC must be at least as high as the ATWACCs of Dr. Vilbert’s 27 samples. 39 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 2 3 A. Q43. How does Gaz Métro’s allowed return under the current, formula-based 4 5 GAZ MÉTRO’S ALLOWED RETURN COMPARED TO ALLOWED RETURNS FOR U.S. LDCS methodology compare to allowed returns for U.S. LDCs? A43. Gaz Métro’s allowed return on capital under the formula is significantly below the 6 returns allowed by regulators for LDCs in the U.S. I have compared Gaz Métro’s after- 7 tax weighted average return on capital (“ATWACC”) under the Régie’s formula with the 8 allowed returns (ATWACCs) awarded for U.S. LDCs by state regulatory commissions 9 during the period January 1999 – August 2008. The results are shown in Figure 16 below. 10 They show that during the period that the Régie-approved formula has been in place, 11 allowed returns for U.S. LDCs have always been greater than Gaz Métro’s allowed 12 return.

Notes: Assumes a 4.6% after-tax cost of debt. Treats preferred equity as debt. 40 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q44. Is this difference in allowed returns for Gaz Métro and for U.S. LDCs caused by a 2 3 difference in allowed return on equity or a difference in financial risk? A44. Gaz Métro’s allowed return on capital is lower than that of U.S. LDCs because its 4 allowed return on equity is lower than that of U.S. LDCs, and because its equity thickness 5 tends to be lower than that of U.S. LDCs. In Figure 17, I plot the allowed returns on 6 equity against the equity thickness for Gaz Métro and for the U.S. LDCs shown in Figure 7 16. Most U.S. LDCs have equity thicknesses in the range of 40 to 60 percent, implying 8 that their equity investors face lower financial risk than do equity investors in Gaz Métro. 14.00% Figure 17 Gaz Métro's Authorized ROE and Equity Thickness Compared to Authorized ROE and Equity Thickness for US LDCs Jan 1999-Oct 2008 13.00% Authorized ROE for US LDCs Authorized ROE 12.00% 11.00% 10.00% 9.00% Gaz Métro's Authorized ROE 8.00% 30.00% 40.00% 50.00% 60.00% 70.00% 80.00% 90.00% Common Equity % Capital 9 Source: "Regulatory Focus", Regulatory Research Associates, RoE Public Utilities Fortnightly 2006, 2007 and 2008 Surveys, Brattle research. 41 100.00% WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q45. Given the differences in the regulation of local distribution companies between 2 Canada and the U.S., why should the Régie consider comparisons of allowed returns 3 across the two jurisdictions? 4 A45. First, while there are some differences in regulatory procedure between Canada and the 5 U.S., the differences are not so great as to make comparisons in Canadian and U.S. 6 allowed returns irrelevant. When it comes to the element of risk that matters most to 7 investors (i.e., long-term earnings and capital cost recovery), the regulatory regimes on 8 both sides of the border have fundamentally the same design. Under traditional cost of 9 service regulation in both Canada and the U.S., utilities are permitted to recover their 10 invested capital (which is measured as depreciated original cost) plus a reasonable return 11 on their investment. This allowed return should meet three standards. It should be 12 equivalent to returns available for investments of comparable risk, it should be adequate 13 to maintain the utility’s financial integrity, and it should allow the utility to attract capital 14 on reasonable terms. These fundamental similarities between the economics of U.S. and 15 Canadian utilities operating under traditional cost of service, and the way they are 16 regulated, make comparisons of allowed returns between the two jurisdictions highly 17 meaningful. 18 While there are differences in regulatory context between the two countries, these 19 differences primarily affect earnings variability risk and not fundamental capital recovery 20 risks. Canadian utilities are generally subject to annual determinations of their cost of 21 service, and utilize deferral accounts to adjust for differences between forecast and actual 22 revenues and costs between annual rate cases. In the U.S., utility rate cases are relatively 23 infrequent, and utilities typically do not utilize deferral accounts to adjust for deviations 24 in revenues and costs. These differences can cause year-to-year returns on U.S. utilities to 25 be more variable relative to allowed returns than year-to-year returns on Canadian 26 utilities. While U.S. utilities may have higher variability risk because of these differences, 27 undue emphasis should not be placed on variability risk because it is fundamental risk 28 that matters most to investors. This difference in earnings variability risk does not make 29 comparisons between U.S. and Canadian utilities inappropriate. Rather, the similarities in 42 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 fundamental risks and capital recovery make comparisons between U.S. and Canadian 2 utilities appropriate.29 3 Q46. You’ve stated that it is appropriate to compare utilities that operate under 4 traditional cost of service regulation in Canada and the U.S., but Gaz Métro 5 operates under a performance incentive mechanism, not traditional cost of service 6 regulation. How does Gaz Métro’s risk under its Performance Incentive Mechanism 7 compare to the risk of U.S. utilities operating under traditional cost of service 8 regulation? 9 A46. In general, Gaz Métro’s Performance Incentive Mechanism exposes equity investors to 10 greater business risks than would traditional cost of service regulation. This is primarily 11 due to the productivity gains and overearnings sharing and service performance threshold 29 The NEB recently found that U.S. comparisons were highly relevant for determining the allowed return for the TQM pipeline, which serves Québec. The NEB stated: In the Board’s view, global financial markets have evolved significantly since 1994. Canada has witnessed increased flows of capital and implemented tax policy changes that facilitate these flows. As a result, the Board is of the view that Canadian firms are increasingly competing for capital on a global basis. The Board notes that Canada has been diversifying its business partners such that there is currently proportionally less Canadian foreign direct investment in the United States than there was in the 1990’s. Nonetheless, the evidence is also clear that the United States is the single most important recipient of Canadian investments. A fair return on capital should, among other things, be comparable to the return available from the application of the invested capital to other enterprises of like risk and permit incremental capital to be attracted to the regulated company on reasonable terms and conditions. TQM needs to compete for capital in the global market place. The Board has to ensure that TQM is allowed a return that enables TQM to do so. Comparisons to returns in other countries would be useful, but challenging, in terms of differences in business risks and business environment. As a result, the Board is of the view that pipeline companies operating in the U.S. have the potential to act as a useful proxy for the investment opportunities available in the global market place. ****** Overall, the Board finds that the risks resulting from the regulatory environment are higher for U.S. pipelines than for Canadian pipelines, and finds that this was also true in 1994. However, the Board is of the view that the risks faced by TQM and those faced by U.S. pipelines are not so different as to make them inappropriate comparators. The Board accepts that there are many similarities between the risks faced by pipelines in the two countries. This is due to the two regulatory models sharing, to a large extent, the same fundamental principles. Moreover, Canadian and U.S. pipelines operate in what the Board views as an integrated North American natural gas market, which informs the choices made by regulators in the different jurisdictions. See National Energy Board, RH-1-2008, pp. 66-68. 43 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 features of the Performance Incentive Mechanism. How much greater the risk is depends 2 on the particular form of cost of service regulation to which it is being compared. In the 3 U.S., most cost of service regimes do not make extensive use of deferral accounts, and 4 many do not require utilities to file frequent rate cases. Under this approach the regulator 5 is making use of “regulatory lag” (the time between cost-of-service rate cases) as an 6 incentive mechanism, i.e., to the extent the utility is able to reduce costs or increase 7 productivity between rate cases, its earned returns will vary between rate cases because 8 rates do not change between cases. As a result, this approach to cost of service regulation 9 exposes utilities to somewhat greater business risks than does traditional cost of service 10 regulation with “true ups” as often practiced in Canada. 11 Gaz Métro’s Performance Incentive Mechanism exhibits some of the characteristics of 12 cost of service regulation with regulatory lag. However, it is a riskier regime than US- 13 style regulatory lag because the revenue cap includes the effect of projected productivity 14 gains that must be shared with Gaz Métro’s customers before any gains or overearnings 15 accrue to Gaz Métro’s shareholders. As a result, if Gaz Métro performs well under its 16 performance incentive scheme, most of the out-performance is passed on to its customers 17 immediately as reduced rates. Furthermore, when the performance incentive mechanism 18 ends Gaz Métro could be in a position of having to pay off accrued underperformance 19 under the mechanism. 20 Q47. Would it also be meaningful to compare the allowed returns of local distribution 21 22 companies such as Gaz Métro with those of transmission pipelines? A47. Yes. Local distribution companies and transmission pipelines are all asset-intensive, 23 regulated enterprises that are in sufficiently similar businesses that comparing their 24 allowed returns is meaningful. The differences between LDCs and transmission pipelines 25 from a business risk perspective largely involve the level of competition that they face in 26 the markets they serve. Many pipelines face market risk due to competitive bypass 27 because they own transmission or storage assets that serve third parties in competition 28 with other facilities. While most LDCs do not face bypass risk in their franchised service 44 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 territories, some LDCs do face significant market risk, either due to competition from 2 alternative fuels or from the loss of industrial load due to economic conditions, and thus 3 they may face market risk similar to that of transmission pipelines. Gaz Métro certainly 4 falls within that category. 5 Q48. Is there a difference between the allowed returns required for new and existing 6 7 natural gas infrastructure? A48. No there is not. To create a dichotomy between new and existing infrastructure with 8 respect to the allowed return on capital is bad policy and would be economically 9 inefficient. As long as new and existing investments face the same risks over their 10 lifetimes, there is no difference in the market’s required return on capital for such 11 investments. To treat them differently would create a “vintaging” problem, where new 12 investment would be encouraged at the expense of upgrading or expanding existing 13 infrastructure. Such a policy would be inefficient because it will create incentives for 14 suboptimal investment decisions. 15 B. 16 Q49. How does Gaz Métro’s business environment compare to other LDCs in Canada 17 18 GAZ MÉTRO’S UNIQUE BUSINESS ENVIRONMENT and the U.S.? A49. Gaz Métro’s business environment is unique compared to other LDCs in Canada and the 19 U.S. in at least three respects: (1) natural gas has a significantly lower penetration rate in 20 Québec, in Gaz Métro’s service territory, than in the service territories of typical LDCs in 21 Canada and the U.S.; (2) Gaz Métro faces significantly stronger competition from 22 electricity than other LDCs in Canada and the U.S.; and (3) Gaz Métro has a large 23 industrial customer load, an industrial customer load that is larger than the LDCs in Dr. 24 Vilbert’s U.S. LDC sample. 45 WRITTEN EVIDENCE OF PAUL R.

Natural gas usage for home heating is significantly lower in Québec than in all Canadian 5 provinces except the Atlantic provinces. See Figure 18 below, which was compiled using 6 data from Natural Resource Canada for 2006.

Q52. How competitive is natural gas with electricity in other Canadian provinces and in 4 5 Competition from Electricity the U.S.? A52. Electricity rates are significantly higher in most other major cities in Canada and the U.S. 6 than in Québec. Therefore, electricity has a greater competitive advantage compared to 7 natural gas in Québec than in most other major cities in Canada and the U.S. Figure 18 8 uses data from Hydro-Québec to compare residential electricity rates in major North 9 American cities as of April 2008. Figure 22 shows that only residential rates in Winnipeg 10 and Seattle were lower than residential rates in Québec as of April 2008. The pattern is 11 similar for larger commercial and industrial customers. 49 WRITTEN EVIDENCE OF PAUL R.

Notes: Rates are in Canadian dollars and exclude taxes. 1 2 Nashville, TN (Nashville Electric Service) 0 Portland, OR (Pacific Power and Light) 5 competition? A53. The Green Fund levy is paid by energy distributors, including Gaz Métro, and in Gaz 5 Métro’s case the levy is passed through directly to customers. The effect of the levy is to 6 increase the delivered natural gas cost paid by consumers. In particular, the cost of 7 natural gas is increased relative to the cost of electricity. It therefore further increases the 8 pressure on natural gas from competition with electricity. 9 Q54. How does Gaz Métro’s growth rate in the home-heating market compare to other 10 11 jurisdictions? A54. Gaz Métro’s penetration rate in housing starts in Québec is significantly lower than the 12 penetration rate for natural gas in new, single-family homes in the U.S. Gaz Métro 13 supplied natural gas to 12.3% of all housing starts in Québec in 2008 and 8.9% of all 50 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 housing starts in Québec in 2007, while natural gas was used to heat 60% of newly 2 constructed single family homes in the U.S. in 2007.30 Gaz Métro had a lower penetration 3 rate in new residential housing despite its significant spending on advertising and other 4 market initiatives. 5 Despite any success Gaz Métro has had supplying new housing with natural gas, 6 electricity remains the dominant fuel for home heating in Québec. See Figure 18 above 7 (which looks at the fuel mix for home heating in Québec and other Canadian provinces in 8 2006) and Figure 23 below, which looks at the percentage of homes in Québec heated by 9 natural gas during 1997-2007. The share of homes in Québec heated by electricity has 10 been over 70% in recent years, while the share of homes in Québec heated by natural gas 11 has remained fairly steady at only 5-6%. This is in stark contrast to the situation in 12 Ontario, where natural gas is the dominant fuel, or Canada as a whole, where around half 13 of all homes are use gas.

Q55. What portion of Gaz Métro’s load is represented by deliveries to industrial 4 5 Gaz Métro’s Industrial Customer Load customers? A55. In fiscal year 2008, approximately 52% of Gaz Métro’s load (measured on a normalized 6 basis) was deliveries to industrial customers.31 In fiscal year 2007, approximately 57% of 7 Gaz Métro’s load (measured on a normalized basis) was deliveries to industrial 8 customers. 31 Gaz Métro Limited Partnership Annual Information Form, Fiscal Year Ended September 30, 2008, p. 21. 53 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q56. How does Gaz Métro’s industrial load compare to that of other LDCs in the U.S.? 2 A56. Figure 25 below compares Gaz Métro’s industrial load in fiscal year 2007 to the 3 industrial load in calendar year 2007 of the U.S. LDCs in Dr. Vilbert’s pure play U.S. 4 LDC sub sample.32 It shows that Gaz Métro’s industrial load was higher than each of the 5 U.S. LDCs in Dr. Vilbert’s sub sample.

A57. Gaz Métro’s relatively large industrial load increases its business risk. Industrial 10 customers tend to have loads that are more variable and unpredictable than other 11 customer classes. They tend to have a greater ability to switch from natural gas to 32 Attachment B to my testimony describes the LDCs in Dr. Vilbert’s pure play U.S. LDC sub sample in greater detail. 54 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 competing fuels (particularly fuel oil) when natural gas commodity prices rise relative to 2 the prices of competing fuels. Moreover, in recent years many industrial customers have 3 decreased the size of their operations or have shut down in response to macroeconomic 4 conditions and fuel costs. This greater variability in industrial customers’ load is 5 particularly striking when compared to load variations for residential and commercial 6 customers (SML customers). SML customers’ load varies due to changes in weather and 7 to increased energy conservation. However, these more predictable variations can be at 8 least partially addressed through weather normalization mechanisms and through 9 mechanisms like that recently incorporated into Gaz Métro’s Performance Incentive 10 Mechanism that is meant to account for declining customer usage. 11 The 2009 performance incentive mechanism results illustrate how Gaz Métro is exposed 12 to business risk through exposure to declining volumes for industrial customers. 13 14 C. 15 Q58. How does Gaz Métro’s risk compare with the U.S. LDCs included in Dr. Vilbert’s 16 17 GAZ MÉTRO’S LONG-TERM RISK IS GREATER THAN THAT OF THE U.S. LDCS IN DR. VILBERT’S PURE PLAY SUB SAMPLE pure play U.S. LDC sub sample? A58. In my opinion, the eight companies in Dr. Vilbert’s pure play U.S. LDC sub sample are 18 of lower risk than Gaz Métro. The eight companies in this sub sample were selected 19 because they represent relatively “pure play” U.S. LDCs, with operations concentrated in 20 regulated gas distribution and assets largely devoted to traditional LDC service. The 21 fundamental long-term risk of the companies in Dr. Vilbert’s sub sample are lower than 22 Gaz Métro’s because the companies in Dr. Vilbert’s sub sample have smaller industrial 23 load, face less competition and have lower regulatory risk (since their rates are 24 determined using traditional cost of service methodologies and many employ 25 mechanisms like rate decoupling that reduce their short-term revenue variability). 26 I have included a table as Attachment B to this evidence that presents information useful 27 in assessing the risk of the eight U.S. LDCs included in Dr. Vilbert’s sub sample relative 55 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 to Gaz Métro’s risk. The table presents information on business activities by segment 2 (distribution, transmission and storage), distribution service customer mix, and bypass 3 risk for distribution customers. It also presents information on how rates are determined, 4 including the use of decoupling or margin stabilization mechanisms, weather 5 normalization and gas cost adjustment mechanisms. Finally, the table presents 6 information on the diversified (unregulated) activities of the holding companies in Dr. 7 Vilbert’s pure play U.S. LDC sub sample. 8 Q59. Please explain with reference to Attachment B how you reached the conclusion that 9 10 Dr. Vilbert’s U.S. LDC sub sample is a relatively “pure play” LDC sample. A59. The eight companies in Dr. Vilbert’s sub sample have operations concentrated in 11 regulated gas distribution. I base this conclusion on two factors. First, the companies in 12 Dr. Vilbert’s sub sample derive most of their income from regulated gas distribution 13 services. Please refer to the rows labelled “LDC Net Income as a Percentage of the 14 Company’s Net Income in 2008” on pages 2 and 4 of Attachment B. The companies in 15 Dr. Vilbert’s sample derived from 51 percent - 98 percent of their net income from 16 regulated distribution activities in 2008. Similarly, between 76 percent - 97 percent of 17 these companies’ assets were committed to regulated distribution activities in 2008. 18 Second, while six of the eight companies in Dr. Vilbert’s sub sample have lines of 19 business that involve the provision of competitive storage and transportation service, 20 these lines of business represent an insignificant portion of these companies’ overall 21 activities. Please refer to the rows labelled “Interstate Storage and Transportation” on 22 pages 1 and 3 of Attachment B. Finally, unregulated activities make up a small portion of 23 the business activities of the companies in Dr. Vilbert’s sub sample. Please refer to the 24 rows labelled “Diversified Activities” on pages 2 and 4 of Attachment B. Therefore, I 25 conclude that Dr. Vilbert’s U.S. LDC sample represents a “pure play” LDC sample. 56 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q60. Please explain with reference to Attachment B how you reached the conclusion that 2 the companies in Dr. Vilbert’s U.S. LDC sample are exposed to lower fundamental 3 risk than Gaz Métro. 4 A60. I conclude that the companies in Dr. Vilbert’s U.S. pure play LDC sub sample have lower 5 fundamental risk than Gaz Métro because the companies in Dr. Vilbert’s sub sample have 6 smaller industrial load and face a lesser degree of competition than Gaz Métro. The 7 companies in Dr. Vilbert’s sub sample appear to face weaker competition from electricity 8 than Gaz Métro. See the rows labelled “Competition with Electricity” on pages 1 and 3 of 9 Attachment B. In 2007, average residential electric rates in the states in which these 10 companies operate were higher than Hydro-Quebec’s average residential rate. Moreover, 11 their distribution services do not face a great degree of bypass risk. Three of the eight 12 companies in Dr. Vilbert’s sub sample (Laclede Group, Nicor Inc. and WGL Holdings) 13 serve customer bases that largely consist of residential and commercial customers that are 14 not at risk of bypass. Please refer to the rows labeled “Customer Mix” on pages 1 and 3 15 of Attachment B. One additional company (South Jersey Industries) has higher industrial 16 and electric generator throughput, but does not appear to face significant bypass risk; 17 South Jersey does not discuss bypass as one of its risk factors in its annual reports to 18 investors (the SEC Form 10-K). Three of the remaining four companies, (NICOR, Inc., 19 Northwest Natural Gas, Piedmont Natural Gas and Southwest Gas) serve significant 20 industrial and electric generation load. According to their 10-K’s, these companies have 21 been successful at using negotiated rates to prevent bypass of their systems.33 Please refer 22 to the rows labeled “Bypass Risk” on pages 2 and 4 of Attachment B. Thus, I conclude 23 that the companies in Dr. Vilbert’s sample face lower fundamental risk than Gaz Métro 24 since the companies in Dr. Vilbert’s sample are not exposed to competition to the same 25 degree as Gaz Métro. 33 The remaining company, AGL Resources, states in its 2008 SEC Form 10-K that it faces bypass risk, and does not discuss whether it can mitigate this risk through the use of negotiated agreements. 57 WRITTEN EVIDENCE OF PAUL R. CARPENTER 1 Q61. Please explain with reference to Attachment B to your evidence how regulatory risk 2 3 of the companies in Dr. Vilbert’s sample compare to Gaz Métro’s regulatory risk? A61. The LDCs owned by the companies in Dr. Vilbert’s pure play U.S. LDC sub sample tend 4 to have rates set by traditional cost of service methodologies. Many of them (all but 5 Laclede Group and NICOR Inc.) also have decoupling or margin stabilization 6 mechanisms that reduce the short-term variability of their earnings for some of their 7 utility subsidiaries. Please refer to the rows labeled “Decoupling Mechanism” on pages 2 8 and 4 of Attachment B. As I have discussed, Gaz Metro’s Performance Incentive 9 Mechanism is a riskier regime than traditional cost of service regulation as it is employed 10 in the U.S. Thus, Gaz Metro’s regulatory risk is somewhat higher than that of the 11 companies in Dr. Vilbert’s pure play U.S. LDC sub sample. 12 Q62. Please summarize your conclusion regarding the risk of Gaz Métro compared to the 13 14 risk of Dr. Vilbert’s pure play U.S. LDC sub sample. A62. I conclude that Gaz Métro faces more risk than the companies in Dr. Vilbert’s pure play 15 U.S. LDC sub sample. Gaz Métro faces more fundamental risk and somewhat higher 16 regulatory risk than the companies in Dr. Vilbert’s sub sample. 17 Q63. Does this complete your written evidence? 18 A63. Yes. 58
