California suspended deregulation on September 20th, 2001. Customers who had already switched to an alternative supplier (called an Electric Service Provider or ESP in California) retained the ability to choose even if they returned to “bundled service” with Pacific Gas & Electric, Southern California Edison, or San Diego Gas & Electric. If the customer returned to the utility for supply, they are required to give the utility six months advance notice before they can leave again for an alternative energy provider. California reintroduced limited deregulation in 2010. Participation in alternative supply was capped of less than 25,000,000 megawatt hours (MWh) with the first scheduled opening on April 16, 2010 and the second on July 16, 2010. In each case, the cap was hit within less than a minute after registration opened. Only 835,000 MWh (about 10% of the cap) are left to be implemented for delivery in 2013.

Customers can choose a different company to supply them with their gas supply. Customers choosing an alternate gas supplier have their gas supply delivered by the local utility. If customers do not shop for an alternate gas supplier, they receive default sales service from their utility. Sales service is structured depends on the size of the customer. California has split customers into “core customers” and “non-core customers”. Core customers include commercial customers with annual loads below 250,000 therms, and those commercial customers with annual loads above 250,000 therms who elect to receive the higher reliability associated with core service. Non-core customers include all cogeneration customers, regardless of load size, and those commercial customers with annual loads above 250,000 therms. Under default sales service, customers pay a supply charge called “gas energy charge” which varies monthly.
