The 2017 Power Content Labels are available.

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.

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 in progress.
