Peak Day Partners

Ensuring grid reliability together 

During extreme warm weather, the electric grid in California can be strained due to high demand.  This can lead to the use of dirtier energy or even rotating power outages. 

Through Peak Day Partners, businesses and CleanPowerSF can work together to support grid reliability during extreme weather events. Participants who take action on Event Days can benefit from financial incentives -- risk-free. 

Together, we have the power to make a difference.


We developed a multi-pronged approach to conserve energy – everything from turning off unnecessary lights, to adjusting temperature settings, and running the chiller earlier in the day. All these tasks are done manually, so we developed a checklist. We also communicated with our tenants, who were eager to reduce their energy load. All the coordination was well worth making a positive impact and lessening the strain on California’s electric grid – that’s our main motivator.”
— Stephen Francisco, Chief Engineer of 555 California
