SDG&E’s 2018 RFO Seeking Green Tariff Shared Renewable Program Power Purchase Agreements

In accordance with Decision (D.)16-05-006, D.15-01-051, D.17-07-007 and Resolution (R-)4734 (together the GTSR Decisions) issued by the California Public Utilities Commission (CPUC or Commission), San Diego Gas & Electric Company (SDG&E) is issuing this Green Tariff Shared Renewables (GTSR) Program joint RFO seeking contracts with facilities that produce Renewable Portfolio Standard (RPS)-eligible energy for the purpose of implementing its Enhanced Community Renewables and Green Tariff programs, as described below. 

The GTSR Decisions mandate SDG&E to implement the GTSR Program, which includes two components: (1) a Green Tariff (GT) program (“EcoChoice”), allowing customers to choose a higher percentage of renewable generation than they already get from SDG&E; and, (2) an Enhanced Community Renewables (“EcoShare”), allowing customers to participate in community-based projects. 

The programs are intended to:  1) make clean, renewable energy available to bundled utility customers, whether they own a home and/or can afford a significant capital investment; (2) increase the overall volume of renewable energy in the San Diego area; and (3) increase options for institutional, commercial and residential customers to meet their renewable energy goals.  Overall, SDG&E’s GTSR program is designed to ensure sufficient eligible capacity is available to meet customer demand of up to 59 MW, with 10 MW of the total program capacity being set aside for projects located in designated Environmental Justice areas.

SDG&E will hold two EcoShare auctions in 2018, or until all available GTSR capacity is reserved subject to customer participation in these programs.  In this Spring 2018 GTSR solicitation, SDG&E seeks between .5 - 16 MW of capacity for EcoShare, .5 - 29 MW of capacity for EcoChoice, and .5 – 10 MW of EJ capacity.  Distributed Energy Resource Providers (DERP) participating in the EcoShare program can aggregate resources to meet the CAISO 0.5 MW minimum size requirement to bid into the market.   Offers consisting of DERP resources are eligible to bid into this solicitation provided they meet the other requirements outlined in the EcoShare solicitation document.   This solicitation is not requesting bids for feed-in-tariff projects (e.g. Re-MAT, Bio-MAT), BioRAM, or other RAM or RPS procurement activities that currently exist or are being contemplated.
