The Energy Commission’s Power Source Disclosure program provides consumers a detailed view into the sources of energy purchased by their retail suppliers to power their homes and businesses.
This information is provided through annual Power Content Labels, which resemble nutrition labels, with a breakdown of energy sources such as solar, wind, geothermal, nuclear, large hydroelectric, and natural gas. For comparison, the labels include a summary of California’s energy mix, which is called total system power.
Retail electricity suppliers report their electricity purchases and retail sales to the Energy Commission each year. The reports are used to create the labels for each product offered the prior year.
Tools and resources are available to help retail suppliers meet reporting requirements.
The Power Source Disclosure (PSD) program was established by Senate Bill (SB) 1305 (Stats. 1997, ch. 796) in an effort to provide retail electricity consumers “accurate, reliable, and simple to understand information on the sources of energy that are used to provide electric services.”1 In 2016, the California Energy Commission (Energy Commission) adopted modifications to the regulations to incorporate statutory changes to program rules and reporting requirements as required by Assembly Bill (AB) 162 (Stats. 2009, ch. 313) and AB 2227 (Stats. 2012, ch. 616). AB 1110 (Stats. 2016, ch. 656) modified the PSD Program and Power Content Label by requiring retail suppliers to disclose the greenhouse gas (GHG) emissions intensity (the rate of emissions per unit of electricity) associated with each electricity portfolio beginning in 2020 for the 2019 reporting year. AB 1110 also required the Energy Commission, among other things, to determine a format for disclosing unbundled renewable energy credits (RECs) as a percentage of annual retail sales.
Assembly Bill 1110 (Ting, Chapter 656, Statutes of 2016) calls for significant changes to the program by requiring that retail suppliers disclose greenhouse gas emission intensities for their product offerings in addition to the fuel mix. The rulemaking to implement the changes required by this bill is complete. On May 4, 2020, the Office of Administrative Law approved the AB 1110 regulations and made them effective upon filing to the Secretary of State.
