14. True-Up of interim Rates

By Ruling dated December 23, 2009, we found it in the public interest to grant interim rate relief to Golden State for the two regions in this GRC proceeding. Consistent with Section 455.2, the interim rate increase is based on the rate of inflation as compared to existing rates for each region, is subject to refund, and will be adjusted upward or downward, back to January 1, 2010, based on the final rates adopted by the Commission in this decision.²⁵

Based on our decision today, there will be a surcharge for each region for the period since January 1, 2010. Golden State should recover the surcharge for each region over the remainder of this rate case cycle.

²⁵ The rate of inflation is to be calculated using the most recent Consumer Price Index maintained by the U.S. Department of Labor.
