SCE – Public Utility

SCE is an investor-owned public utility primarily engaged in the business of supplying and delivering electricity through SCE's electrical infrastructure to an approximately 50,000 square-mile area of southern California. SCE serves

approximately 5 million customers in its service area. As of December 31, 2023, SCE's total number of customers by class were as follows:

In 2023, SCE's total operating revenue of $16.3 billion was derived as follows: 42.8% commercial customers, 37.4% residential customers, 4.1% public authorities, 2.7% industrial customers, 4.3% agricultural and other, and 8.7% other operating revenue.

CPUC and FERC rates decouple authorized revenue from the volume of electricity sales and the price of energy procured so that SCE has the opportunity to receive revenue equal to amounts authorized by the relevant regulatory agencies. As a result, the volume of electricity sold to customers does not have a direct impact on SCE's financial results. See "SCE—Overview of Ratemaking Process—CPUC" and "—FERC" for further information.
