The Electric Service Providers (ESPs) on this list are registered with the California Public Utilities Commission (CPUC). Public Utilities Code Section 394 defines an Electric Service Provider (ESP) as a non-utility entity that offers electric service to customers within the service territory of an electric utility. Subparagraph (b) requires each ESP to register with the CPUC and sets forth the registration requirements. The CPUC implemented the framework for ESP registration, specifically applying these requirements to ESPs serving residential and small commercial customers (maximum peak demand less than 20 kilowatts) in Decision no. D.99-05-034 and D.98-03-072. In D.03-12-015, the CPUC extended these requirements to ESPs not previously required to register, as applicable.

Registered ESPs are also required to provide their residential and small commercial customers with a Notice of Terms and Conditions. This is known as a Section 394.5 Notice (P.U. Code section 394.5). You can view a sample notice by clicking on the link.

IMPORTANT! The CPUC has no information that can help in making a decision to invest in an ESP.
