Power Source Disclosure
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.
Signed by Governor Brown in September 2016, AB 1110 (Ting, Chapter 656, Statues of 2016), requires that retail suppliers of electricity additionallly disclose to consumers the greenhouse gas emissions intensity of the supplier's electric service products. This modification to the program will improve transparency for consumers and strengthen the Power Source Disclosure program's relevance to California's climate change activities. The Energy Commission has begun rulemaking procedures to update the Power Source Disclosure regulations to comply with AB 1110. Greenhouse gas emissions data will be included in the Power Content Label beginning in 2020.
