Southern California Gas

What Southern California Gas does

Southern California Gas Company (SoCalGas) is the largest natural gas distribution utility in the United States, serving over 21 million residential, commercial, and industrial consumers across Central and Southern California. Founded in 1867 and headquartered in Los Angeles, SoCalGas operates as a wholly-owned subsidiary of Sempra (NYSE: SRE) under an exclusive service territory franchise regulated by the California Public Utilities Commission (CPUC). The company distributes natural gas through an integrated transmission and distribution pipeline network complemented by four underground storage fields that can supply nearly 60% of system demand during peak events. SoCalGas serves residential customers for heating, cooking, and hot water, as well as commercial, industrial, agricultural, and natural gas vehicle customers across 38 cities and 9 counties.

SoCalGas's technology stack centers on physical pipeline and storage infrastructure, advanced metering systems, and emerging clean energy platforms. Notable technology assets include the H2 Innovation Experience — a first-of-its-kind hydrogen microgrid in Downey, CA featuring solar arrays, battery storage, and an electrolyzer for producing renewable hydrogen from solar energy. The company completed a year-long hydrogen blending demonstration using Bloom Energy's solid oxide electrolyzer at Caltech's Pasadena campus in November 2025, is interconnecting landfill-sourced renewable natural gas (RNG) into its pipeline — beginning with WM Simi Valley in January 2026 — and is pursuing Angeles Link, a proposed hydrogen pipeline system intended to be the nation's largest. SoCalGas is also a partner in a DOE-funded regional direct air capture hub in Kern County targeting one million metric tons of CO2 removal annually, and it filed a joint CPUC petition with SDG&E and Southwest Gas to enable up to 5% hydrogen blending in existing pipelines.

SoCalGas earns revenue through CPUC-regulated rates from residential, commercial, and industrial gas distribution, with the cost of gas passed through to customers without markup. Its revenue model is supplemented by backbone transportation services, natural gas storage capacity rights, Core Aggregation Transportation services for non-core customers, and more than 70 CPUC-approved energy efficiency programs that delivered $106 million in customer savings in 2025 and $1.41 in total customer value per $1 invested. The customer base is dominated by residential users, with the CARE program offering 20% discounts to income-qualified households. Over 20 Core Transportation Agents (including BP Energy, Shell Energy, and Chevron Natural Gas) and 40+ non-core suppliers operate as channel partners. Because SoCalGas operates as a regulated monopoly, revenue and rate changes require CPUC approval, which constrains pricing flexibility but provides regulatory stability and exclusive franchise protection.
