What is the Power Content Label? 

California State legislation (SB 1305) requires all energy service providers, such as Silicon Valley Power, to annually inform their customers of the source of power they are being sold. Such information is provided in the form of a Power Content Label.  Think of the Power Content Label as a “nutrition label” for electricity. This label provides reliable information about the energy resources used to generate electricity, enabling you to easily compare the power “content” of one electricity product with that of another.
