Peninsula Clean Energy is excited to launch this Renewable Energy and Storage Request for Offers (RFO) for Fully Deliverable Renewable Energy and Storage projects.

As part of this RFO, Peninsula Clean Energy seeks renewable energy and/or storage projects that meet the eligibility criteria defined in the CPUC Mid-Term Reliability Procurement Order (MTR Order). Peninsula Clean Energy is seeking 10 MW of capacity that qualifies as Long Duration Storage (8 hour or longer) and can be online by June 1, 2028.
