TURLOCK, California, June 4, 2024: Turlock Irrigation District (TID), a publicly owned irrigation district, announces a request for proposals to meet its California Renewable Portfolio Standards (RPS) and reliability goals. Through the Ascend Analytics Energy Exchange (AEX), TID aims to procure new or existing clean energy projects delivering either directly into TID’s BA, or to CAISO. Offers may be structured as all-in PPAs, bundled RECs (fixed price or Index+), or ownership offers. All offers must have a minimum nameplate capacity of 50 MW or annual renewable generation of at least 150,000 MWh. Acceptable commercial operation dates are no later than December 31, 2030.  

TID seeks proposals for PCC1 eligible renewable generation (including solar photovoltaic, wind, biomass, biofuel, small hydroelectric generation, and geothermal) or PCC1 renewable generation plus storage (hybrid). Storage discharge duration must be at least 4 hours. Offers are grouped in two categories:  

  1. Group A: Proposals for direct delivery to TID's BA system:
    • Power Purchase Agreements (All-In): All-in PPAs must have a term length between 10 and 30 years.
    • Ownership Options: EPC contracts for turnkey projects with the option of offering a long-term service agreement (LTSA).

    • Power Purchase Agreements (All-in, Energy + RECs, Index+): All-in PPAs must have a term length between 10 and 30 years and bundled RECs (fixed price or Index+) must be between 10 and 20 years. Ownership offers will not be considered for Group B projects.
