Community Choice Aggregation (CCA) was passed as California state law in 2002, to enable local communities to stop purchasing power from for-profit utilities, and instead assume the role themselves of providing electricity to their residents and businesses.

It allows us, the people of San Francisco, to form our own nonprofit cooperative for buying and generating electricity.

Using this new state granted authority, the San Francisco Board of Supervisors voted on June 19, 2007 for a bold project, called Clean Power SF, which will shift San Francisco immediately to large scale renewable energy, and soon end our dependence on PG&E's polluting and high priced fossil fuel electricity.

The project will provide cheaper, more reliable energy through development of solar, wind power, efficiency, and conservation measures to meet 50% of the City's electricity needs within the next decade, and at the same or lower rates than PG&E.

Clean Power SF will become the largest green energy project for any single city in the world, and lead the planet toward rapid and real solutions to the climate crisis.
