Power Source Disclosure

Sample Power Content Label

The Power Source Disclosure program was established to provide "accurate, reliable, and simple-to-understand information on the sources of energy that are used to provide electric services" to California consumers (Public Utilities Code Section 398.1(b)).

Enacted in 1997 (Senate Bill 1305, Sher, Statutes of 1997), the law requires that electricity retail suppliers to disclose to consumers which types of resources are used to generate electricity being sold. The suppliers are required to use a format developed by the Energy Commission called the Power Content Label. An example of a Power Content Label is shown on the right. The law also requires retail suppliers to submit a detailed report of their resource mix to the Energy Commission. These reports are available to the public upon request.

The program was significantly changed by Assembly Bill (AB) 162 (Ruskin, Statutes of 2009,) in response to many changes in the electricity market since 1997, including the development of the Renewables Portfolio Standard (RPS), which currently requires California’s electricity mix to be 33 percent renewable by 2020, and 50 percent renewable by 2030.

As of July 2016, the Energy Commission adopted modifications to the existing regulations for the Power Source Disclosure program to incorporate changes made by AB 162. The effective date for the adopted regulations is tentatively set for January 1, 2017. All retail suppliers of electricity should use the AB 162-compliant annual report schedules and the power content label template provided below to complete each year's reporting.
