Core Transport Agents
Core Transport Agents (CTAs) are non-utility suppliers that purchase natural gas on behalf of residential and small business customers, offering an alternative to utility gas supply from companies such as PG&E, SoCalGas, SDG&E, and Southwest Gas. Customers who choose CTA service continue to receive gas delivery through their local utility’s pipelines and pay the utility for delivery services.
In 1991, the California Public Utilities Commission (CPUC) opened the natural gas procurement market to competition, allowing customers to choose who supplies their natural gas. Additional CTA registration and consumer-protection requirements were established in 2013 through Senate Bill 656. CTAs must demonstrate operational, technical, and financial qualifications to register in California. While the CPUC does not regulate CTA rates, it monitors marketing practices and customer complaints and may impose penalties for violations of applicable requirements.
The CPUC also compiles and publishes information on CTA complaints and prices to assist customers in comparing service options. Customers are encouraged to review and compare CTA offers, prices, and terms with those of other CTAs and their local utility before enrolling.
