2024 RFO for Renewable Energy + Storage

Offers due Friday June 28, 2024, at 5 p.m. Pacific Prevailing Time (PPT)


Peninsula Clean Energy is excited to launch this Request for Offers (RFO) for Renewable Energy and Storage projects. Peninsula Clean Energy is soliciting competitive proposals for the purchase of renewable energy and storage contracts to fulfill our energy goals, specifically Peninsula Clean Energy’s goal to serve our customers’ electricity needs with 100% renewable energy by 2030.

The goal of this Request for Offers for Renewable Energy + Storage (“RFO”) is to provide a competitive, objectively administered opportunity for suppliers to propose projects to fulfill Peninsula Clean Energy’s desire for renewable and storage resources that have a commercial on-line date of December 31, 2030 or earlier. Peninsula Clean Energy prefers projects that have received Full Capacity Deliverability Status, or equivalent from CAISO but will consider Energy Only projects as well.

This RFO is intended for projects in CAISO’s Cluster 14 or earlier. Peninsula Clean Energy will NOT consider offers for projects in CAISO’s Cluster 15 as part of this RFO, unless they are WDAT projects not subject to LSE Point Allocation.
