The Sidney Frank Foundation has provided a $250,000 grant to analyze how to power the San Francisco’s 950 MW peak energy use with only renewable energy by 2020.

The city’s Sunset Reservoir Solar Project, a 5 MW solar photovoltaic system on top of the city’s largest reservoir, is almost completed, with that project alone tripling San Francisco’s municipal solar generation.

Utility provider PG&E currently produces 16% of its energy from renewable sources, and has plans to expand. San Francisco plans to launch a 1 MW to 3 MW wave energy project in 2011, which may be the precursor to a larger 30 MW to 100 MW wave project. The city also produces 3.5 MW of biogas and 10 MW of distributed solar.
