Power Sources

Sonoma Clean Power is committed to reducing greenhouse gas emissions, supporting our local economy and providing competitively priced service. That’s a lot of goals, and no one power source can deliver all of them.

That’s why we use a combination of sources.  42% of the energy delivered through SCP’s default CleanStart service currently comes from renewable sources, and that’s growing quickly to 50% by 2020.

Since inception, SCP has saved 420,790 metric tons of carbon dioxide.  This is equivalent to planting nearly 11 million tree seedlings and letting them grow for a decade!

 

 

Qualifying sources (wind, solar, geothermal, etc.): 42%
Large hydropower (also carbon free): 49%
General systems power (diverse source mix): 10%
Local renewable power (starting with geothermal): 100%

For CleanStart, we keep costs competitive by buying a mix of hydropower, geothermal, solar, biomass and wind, and we still use some natural gas sources. We’re aiming to continue reducing our use of fossil sources over time, but we’ve already got a great start. EverGreen uses only 100% local renewable resources, without the use of unbundled renewable energy credits.

 

Geothermal

SCP currently has 30 MW of local geothermal power from the Calpine Geysers facility in Northern Sonoma and Southern Lake Counties which will grow to 50 MW in 2018. We are proud to have the Geysers in our backyard because it is one of the world’s largest geothermal energy fields, which began producing power in 1960.

NetGreen

NetGreen is Sonoma Clean Power’s Net Energy Metering (NEM) program that allows customers to make their meter “spin backward” and offset their electrical usage by installing a generating system (e.g. a rooftop solar system or a wind turbine). SCP’s program has unique benefits to incentivize more local renewable power!

Feed-In Tariff

ProFIT promotes the development of new small-scale wholesale renewable energy facilities in SCP’s service territory by creating a new market for developers to sell energy to SCP with standard rules, standard contract, and a known price.
