QUESTION 2:

Please provide 10 years of historical data (2013-2004) showing the MMcfd and MMbtu curtailed on the Southern System due to the inability of SCG to move gas from the Northern System to the Southern System.

SoCalGas/SDG&E have no such analysis.

7 SAN DIEGO GAS & ELECTRIC COMPANY SOUTHERN CALIFORNIA GAS COMPANY NORTH-SOUTH PROJECT REVENUE REQUIREMENT (A.13-12-013) (1ST DATA REQUEST FROM TURN) ______

QUESTION 8:

In Figure 1 of SCG's application, pg. 14, it shows in the legend "FOREIGN PIPELINE". Please provide a map showing these foreign pipelines and indicate which foreign country owns these pipelines.

RESPONSE 8:

The term “FOREIGN PIPELINE” in Figure 1 of Mr. Bisi’s Prepared Direct Testimony does not indicate ownership by a foreign country. Rather, the term indicates pipelines which neither SoCalGas nor SDG&E own or operate. Those foreign pipelines shown in Figure 1 are: the Mojave Pipeline; the Kern River Pipeline; the Kern/Mojave common pipeline; the North Baja Pipeline; and the PG&E Baja Path transmission pipelines. Maps of these pipelines are equally available to TURN.

QUESTION 10:

Please provide the California Gas Report based historical data for the Southern System for core, noncore firm and noncore interruptible load and separate EG from other noncore.

RESPONSE 10:

SoCalGas and SDG&E object to this question on the grounds that it requests confidential customer-specific information.

10 SAN DIEGO GAS & ELECTRIC COMPANY SOUTHERN CALIFORNIA GAS COMPANY NORTH-SOUTH PROJECT REVENUE REQUIREMENT (A.13-12-013) (1ST DATA REQUEST FROM TURN) ______

QUESTION 11:

Please provide data in machine readable form showing the curtailment of noncore customers on the Southern System by firm and interruptible and EG and non-EG firm and nonfarm customers if the River Route alternative is chosen instead of the proposed route.

RESPONSE 11:

There is no such data.

11 SAN DIEGO GAS & ELECTRIC COMPANY SOUTHERN CALIFORNIA GAS COMPANY NORTH-SOUTH PROJECT REVENUE REQUIREMENT (A.13-12-013) (1ST DATA REQUEST FROM TURN) ______

QUESTION 12:

If SoCalGas/SDG&E were to impose a minimum flow obligation as an alternative method of meeting Southern System minimum flow requirements, please explain what level of flow (for example, as a percentage of deliveries from different customer classes) would be required and how often would such a minimum flow obligation be required based on existing forecasts for 5 and10 years in the future.

RESPONSE 12:

SoCalGas/SDG&E cannot answer this question because the answer would depend on future flows that we are not able to model. However, given that sometimes there is sufficient supply at Blythe and other times there is a Southern System minimum of 800 MMcfd with no market-supplies at Blythe, one can assume the percentage would range from zero to 35 percent (800 divided by a low sendout of 2300 MMcf/d).

There are no such studies.

14 SAN DIEGO GAS & ELECTRIC COMPANY SOUTHERN CALIFORNIA GAS COMPANY NORTH-SOUTH PROJECT REVENUE REQUIREMENT (A.13-12-013) (1ST DATA REQUEST FROM TURN) ______

QUESTION 15:

Re Musich, p. 2:11 – Why is it not “in the economic interest” of shippers to deliver into the Southern System? Please provide any historical price data or future price forecasts that explain this behavior.

RESPONSE 15:

The table below compares the average ICE day-ahead price at Ehrenberg with the average prices at SoCalGas’ other receipt points on the days in which the other receipt points traded. (Unlike Ehrenberg, the other points do not trade every day). The table shows a significant and growing price disadvantage at Ehrenberg vis-à-vis all the other points. This means that on most days of the year, Ehrenberg is the last point that suppliers want to use to meet their Southern California customers’ needs. This explains why customers’ supplies at Ehrenberg keep declining each year.

QUESTION 16:

Re. Musich, p. 5, Figure 1 – Please explain the causes of the increase in the minimum requirements since 2008, identifying all relevant factors that contribute to the increase. Please quantify the impact(s) of any factor(s) if possible.

RESPONSE 16:

Southern System electric generation has increased since the SONGS outage. See slide 4 from the May 8, 2014 Customer Forum (provided below for convenience). In addition, pipeline maintenance over the last several years has occasionally reduced SoCalGas’ normal ability to flow 150-300 MMcfd of Northern supplies to the Southern system.

QUESTION 17:

Re Musich, p. 17:14-20 – Does Ms. Musich contend that if SCG/SDG&E contracted for firm supply and capacity, the situation for Southern System minimum flow would be unchanged? Is it possible to solve the minimum flow requirement by holding capacity and supply to Blythe, aside from any operational problems along the relevant El Paso pipeline and associated supply basins?

RESPONSE 17:

No, Ms. Musich contends that the minimum flow requirement itself would be unchanged. No, the minimum flow requirement is not a function of interstate capacity holdings.
