______________________________________________________________________
QUESTION 1:
On page 3 of his testimony Mr. Anderson notes that “The gas commodity price used in
this forecast is discussed in the testimony of Mr. Emmrich.” Is this the same WACOG
price show on Table 10 (p. 14) of Mr. Emmrich’s Gas Throughput forecasting
workpapers.
RESPONSE 1:
The gas commodity price used is the California Border Spot Price Forecast (page 343 in
the Workpapers of Herbert S. Emmrich Demand Forecast 1 of 2). The WACOG price on
Table 10 is for Retail Core Customers. The difference between the two forecasts is less
than $0.03/Dth.

QUESTION 2:
On page 3 of his testimony Mr. Anderson explains that: “In addition to existing
generation, plants were added to the supply. In Southern California, plants were
selected as part of recent Investor Owned Utility (IOU) Requests for Offers (RFO) are
also assumed to be added even though they are currently not under construction”.
Please explain the rationale for including these plants not under construction in Electric
Generation Gas demand forecast.
RESPONSE 2:
The units added, that were not under construction, were three combustion turbine (CT)
facilities which the IOU’s announced as winners in their RFO process. We based the in
service dates on the dates from IOU’s applications for approval with the CPUC. We
included these units because CT facilities can be licensed, built and be in service during
the BCAP period even though they are currently not under construction.

QUESTION 3:
Please quantify the impact on Electric Generation Gas demand of excluding plants not
under construction in the BCAP forecast period.
RESPONSE 3:
By excluding plants not under construction, the overall net impact would be less than 1
MMdTh each year over the BCAP period. This impact is small because the power that
would be generated by these new plants would still need to be generated. The
replacement power would likely come from other existing gas plants.

QUESTION 4:
What is the probability that “the Sunrise Powerlink will be in service by 2011.” (Direct
Prepared Testimony of Robert Anderson, San Diego Gas & Electric Company and
Southern California Gas Company, July 2, 2008).
RESPONSE 4:
The probability rests solely upon the CPUC decision expected later in 2008.

QUESTION 5:
Please quantify the impact on Electric Generation Gas demand if the Sunrise Powerlink
does not come on line in 2011.
RESPONSE 5:
If the Sunrise Powerlink does not come on line in 2011, the EG forecast would be 8
MMdTh more in 2011. Over the BCAP period of 2009 - 2011, the average impact would
be 2.7 MMdTh more per year.
