SDG&E’s Fall 2020 RFO Seeking Community Solar Green Tariff Shared Renewable Program Power Purchase Agreements

In accordance with Decision (D.)18-06-027, D.18-10-007, and Resolution E-4999 issued by the California Public Utilities Commission (CPUC or Commission), San Diego Gas & Electric Company (SDG&E) is issuing this Community Solar Green Tariff (“CSGT”) Request for Offers (RFO or the solicitation) seeking contracts with solar generating facilities that produce Renewable Portfolio Standard (RPS)-eligible energy for the purpose of implementing its CSGT program.    

Pub. Util. Code § 2827.1 required the Commission to develop specific alternatives designed to increase adoption of renewable generation in disadvantaged communities (DACs). 

The CSGT program is intended to provide low-income households located in a census tract that is in the top 25% statewide disadvantaged communities or in the highest 5% of CalEnviroScreen’s Pollution Burden that do not have a CalEnviroScreen Score, as well as contain a border that is within 5 miles of a designated CSGT renewable generating facility, to meet 100% of residential electric needs through local renewable generation and receive a 20% bill discount from their current electric rate.  Community sponsors can also receive up to 25% of the project’s generation capacity.

This solicitation is not requesting bids for feed-in-tariff projects (e.g. Re-MAT, Bio-MAT), BioRAM, EcoChoice, Disadvantaged Community Green Tariff or other RPS procurement activities that currently exist or are being contemplated.

Overall, SDG&E’s CSGT program is designed to ensure sufficient eligible capacity is available to meet customer demand of up to 5 MW.  SDG&E is soliciting CSGT projects that are classified as eligible renewable resources.  Projects must be located within SDG&E’s service territory, as well as within a top 25% of disadvantaged communities or in the highest 5% of CalEnviroScreen’s Pollution Burden that do not have a CalEnviroScreen Score.  For purposes of CSGT, a DAC is a community that is identified, by using CalEnviroScreen 3.0, as among the top 25% of communities statewide, as well as census tracts in the highest 5% of CalEnviroScreen’s Pollution Burden that do not have a CalEnviroScreen Score.  CalEnviroScreen identifies California communities that are most effected by and vulnerable to sources of pollution.
