SDG&E’s Fall 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) E-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 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 program (“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.

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 (EJ) areas.  These EJ areas are top 20% disadvantaged communities as determined by CalEnviroScreen.  SDG&E has held four solicitations for GT and four solicitations for ECR, this solicitation marks SDG&E’s fifth solicitation for both programs.  To date, SDG&E has procured 40 MW for EcoChoice and 2.4 MW for EcoShare.  To date, no projects procured or bid into previous solicitations have qualified for EJ.

SDG&E is directed to hold two ECR solicitations per  year through 2018 if program capacity remains.  Of SDG&E’s 59 MW capacity target, 16.6 MW of capacity remains.  In this Fall 2018 GTSR solicitation, SDG&E seeks .5 up to 13 MW of capacity for EcoShare, .5 up to 5 MW of capacity for EcoChoice, and .5 up to 10 MW of EJ capacity.  

SDG&E seeks new renewable energy located within SDG&E’s service territory or Imperial Valley, with PPA delivery terms of 10-years, 15-years or 20-years.  Qualifying criteria for new energy being solicited is outlined in SDG&E’s Protocol documents.
