Summary
On September 1, 2016, Edison International's subsidiary, Southern California Edison (SCE), filed its 2018 General Rate Case (GRC) application with the California Public Utilities Commission (CPUC) for the three-year period 2018-2020. SCE is requesting an increase in its authorized revenue requirement, starting with $5.885 billion for Test Year 2018, representing a 2.7% increase over 2017 authorized rates. The application also proposes revenue requirement increases of 4.2% in 2019 and 5.2% in 2020, totaling significant requested increases over the three-year period. The primary drivers for this request are substantial investments needed in electric infrastructure to replace aging equipment, enhance capacity for customer and load growth, improve safety and reliability, and integrate increasing amounts of distributed energy resources (DER). SCE projects a total capital program of $23.3 billion from 2016 through 2020, with a forecast weighted-average rate base increasing to $35.1 billion by 2020, reflecting an 8.5% compound annual growth rate. Notably, a significant portion of the capital expenditure request, approximately $2.1 billion, is dedicated to grid modernization.
