Customer Choice Gas Suppliers/ Core Transport Agent (CTA's)



At SoCalGas® we believe that customer choice can result in lower prices and better service. That’s why we want to be sure you are aware of your natural gas purchase options. The CAT program provides core customers using 250,000 therms or less per year, residential customers, and natural gas vehicle customers the option to purchase gas from gas marketers, also known as aggregators.

SoCalGas will continue to provide the same high-quality transportation services for gas purchased from aggregators. Participating customers will pay the aggregator’s gas commodity charges and SoCalGas’ transportation charges.

Aggregators are individuals, companies, or consortiums that arrange for the procurement of natural gas on behalf of customers. Aggregators purchase gas from producers, arrange transportation of the gas (with SoCalGas for the intrastate transportation), and balance gas delivery, storage, and consumption. CAT customers may or may not realize cost savings depending on the contract terms negotiated between the customer and the aggregator compared with SoCalGas’ core customer rates. See the Monthly Savings Estimator for a quick tool that allows customers to estimate the financial outcome in a given month that may be realized from participating in CAT.

SoCalGas' Monthly Gas Procurement Rates may serve as a useful benchmark in evaluating your natural gas procurement options.
