Preliminary Estimate of Efficiency Vermont's ISO-NE Forward Capacity Market Net Revenue 2006 to 2015 Date: 1/1/2008 Author: Michael J. Wickenden, EEU Contract Administrator Net revenue estimates (See EVT ISO-NE FCM Net Revenue Estimate 2006 to 2015 1-1-08.xls) are dependent upon assumptions that all experience uncertainty. The following summarizes the major uncertainties. Revenue Estimates of EVT's Forward Capacity Market (FCM) Revenue are primarily based upon Energy Efficiency Utility (EEU) budget assumptions for 2009 through 2011. The VT Public Service Board authorized EVT to use year 2008 funding ($30,750,000) for years 2009 - 2011 for the purpose of calculating ISO-NE forward capacity market transition period revenue as well as for preparing the documentation for participation in ISO-NE's FCM Auctions (FCMA) #1 and #2. The Board will hold a proceeding in 2008 to formally consider and adopt EEU budgets for 2009 - 2011. If the Board adopts budgets that are less than $30,750,000, and/or if the Board directs EVT to pursue significantly different energy efficiency objectives, the FCM revenue estimates will need to be adjusted downward. Estimates of EVT's net capacity reductions are based upon EVT's best estimates of kW reduction per dollar. If conditions were to change that significantly altered that yield rate, such as new federal or state efficiency standards or substantive changes to the Vermont's economic landscape, that yield could decrease resulting in lower revenue estimates. EVT's claims of net capacity reductions are subject to a rigorous measurement and verification process. Although many aspects of this process have been previously employed, there is no certainty that all claims will be validated or that ISO-NE will accept VT's findings at full value. If there are significant reductions from EVT's claims, the resulting revenue will be lower than estimated. FCM Auction (FCMA) #1 takes place in early February 2008. It now appears that there may be more supply than needed. In that case, decisions will be made that could decrease revenue. Given current information, I have reduced initial revenue estimates by 10% to reflect this oversupply. A more precise estimate will be available after the auction closes in mid-February, 2008. FCMA #2 will take place in early 2009 resulting in an additional revenue stream starting in June of 2011. Currently, no attempt has been made here to include a quantification of that revenue stream. It is evident that the capacity reductions bid into FCMA #2 will occur over a much shorter time frame and thus, will be less (given all else is equal) and, because the expected base price per kW reduction will also be less than that received in FCMA #1, it is expected that the additional annual revenue will be significantly less than that being anticipated from FCMA #1. Costs Estimates of EVT's and the Department of Public Service's (DPS) Measurement and Verification (M&V) costs contain a high degree of variability because several required M&V activities have not been employed to the degree now required. Consequently, a conservatively high cost estimate has been used. However, until EVT and the DPS have more experience with the new requirements, there can be no assurance that the cost estimates are too high. FCMA participants are required to post "Financial Assurance" to protect ISO-NE in case of a participant failing to deliver bid capacity. If EVT was unable to provide the capacity reductions in 2010 that it bid in FCMA #1, EVT would forfeit a predetermined amount per kw shortfall. Thus, the revenue estimate would be lower, due to the kW shortfall, and a predetermined penalty would be assessed to enable ISO-NE to purchase kw equal to the shortfall.
