NOTICE OF APPLICATION SOUTHERN CALIFORNIA GAS COMPANY REQUEST TO INCREASE RATES AND REVENUES FOR LAKESIDE PIPELINE LLC’S DAIRY BIOMETHANE PILOT PROJECT APPLICATION FILING 25-08-009 Why am I receiving this notice? On August 15, 2025, Southern California Gas Company (SoCalGas®) and Lakeside Pipeline LLC filed Application 25-04-009 for Lakeside Pipeline LLC’s Senate Bill (SB) 1383 Dairy Biomethane Pilot Project Reasonableness Review with the California Public Utilities Commission (CPUC). The application is requesting a total increase of $ 14.5 million in revenue to recover costs above the approved project estimate of $ 20.2 million, to total $34.7 million. If the CPUC approves this request, SoCalGas will recover the recorded project developer costs in gas rates over a 1-year period beginning after approval of the application and SoCalGas’s costs over the life of the facility. This will increase your monthly bill. Why is SoCalGas requesting this rate increase? The CPUC authorized the Dairy Biomethane Pilot program to implement six dairy biomethane pilot projects pursuant to Senate Bill (SB) 1383 to produce Renewable Natural Gas (RNG) and to demonstrate interconnection to the utilities’ natural gas pipeline system. RNG is an important component of California’s strategy to reduce greenhouse gas (GHG) emissions and achieve climate goals. These Dairy Biomethane Pilot projects support the development and integration of RNG into the state’s energy system. The Dairy Biomethane Pilot projects include SoCalGas facility upgrades and pilot project developer costs. For this application, facility and projects costs were expended by SoCalGas and Lakeside Pipeline LLC (pilot project developer). The project was completed and exceeded its initial forecasts of RNG production and carbon reductions. SoCalGas and Lakeside Pipeline LLC requests the CPUC approve the costs as reasonable and prudent to successfully demonstrate this Dairy Biomethane Pilot project consistent with the goals of SB 1383. How could this affect my monthly gas rates? If SoCalGas’s request is approved by the CPUC, SoCalGas’s rates for gas service will increase. The average residential gas monthly bill using 36 therms per month would increase by approximately $0.12 or 0.1% per month in 2026. The table below does not necessarily reflect the changes that you may see on your bill. Changes in individual bills will also depend on how much electricity or gas each customer uses.
