When customers start their electrical service, they automatically benefit from our CleanStart service. For those dedicated to making an impact on the climate crisis, our EverGreen service delivers 100% clean power that’s produced locally. Customers can reduce their carbon footprint and help create healthy communities. No extra effort required.

Building local, renewable energy

Our community is powering success with ProFIT, our now fully subscribed feed-in-tariff program that offered a new market for developers to sell energy to SCP with standard rules, contracts, and a set price. Although the queue is full and the budget fully subscribed, if you’re interested in selling power to SCP in the future, please subscribe to “Long-Term Renewable Suppliers” email updates on our website.

Completed ProFIT projects

With four ProFIT projects online, we are now generating local, renewable energy for our EverGreen customers. All our ProFIT projects are built in Sonoma and Mendocino counties, with one solar facility located in unincorporated Willits, one in unincorporated Cloverdale, and two located in rural Petaluma.

Thanks to our EverGreen customers, we have two more ProFIT projects in the queue, both located in Petaluma. The more SCP customers that upgrade to EverGreen, the more local renewable sources we can build!

FAQs

Q

Are Sonoma Clean Power’s default CleanStart service and premium EverGreen service really greener than PG&E?

A

Yes. By contracting with cleaner generating sources SCP is able to offer electricity that has fewer greenhouse gas emissions compared to PG&E’s mix.

SCP’s CleanStart service is 49% renewable and 91% carbon-free, from sources considered renewable under California’s regulations, like wind, solar, biomass, and geothermal, and 42% from large hydropower facilities. The remaining power comes from “system power,” which is largely natural gas, but may include some renewables.

EverGreen is 100% renewable power from geothermal and solar generated in SCP’s service territory. The premium for EverGreen is 2.5 cents per kilowatt-hour or about $13 more per month for the average residential customer. For those who want to help pioneer a clean energy economy, you can switch to EverGreen at any time! Learn more.

Q

What are the sources of SCP's electricity?

A

Sonoma Clean Power is committed to increasing renewable energy, supporting the local economy, and providing competitively priced service. That’s quite a few goals, and no one power source can deliver all of them, which is why we use a combination of sources. You can view a breakdown of our current mix on our Power Sources page.
