Trimark Awarded SCADA for World’s Largest PV+BESS Project

The Edwards & Sanborn project redefines the utility-scale PV+Storage landscape.

Folsom, CA, February 17, 2021 Trimark Associates, Inc. is proud to announce our involvement in the Edwards & Sanborn project, the world’s largest solar-plus-storage (PV+BESS) project currently under construction. Located in Kern County, California, the project weighs in at 1,118 megawatts (MW) of solar and 2,165 megawatt-hours (MWh) of energy storage.

The project is owned by Terra-Gen, while Mortenson Construction acts as the Engineering, Procurement, and Construction (EPC) contractor for both the solar and storage. Terra-Gen and Mortenson selected Trimark as a subcontractor for the SCADA portion of the project, which also includes meteorological (“Met”) stations, networking equipment, and a Dynamic Loss Compensation (DLC) system to address Power Purchase Agreement (PPA) requirements. Trimark will also provide complex metering, including CAISO-compliant revenue meters (under a separate contract with Electrical Consultants Inc.).

The latest in a long line of utility-scale PV+BESS SCADA installations under Trimark’s care, Edwards & Sanborn is a massive undertaking, but one that Trimark’s talents are perfectly suited for. Mark Morosky, Trimark’s President and CEO, is excited for Trimark’s involvement: “We’re very proud that Terra-Gen has placed their confidence in Trimark to provide our expertise and skills to control and monitor Edwards-Sanborn, which will be the largest project of its kind in the world. Terra-Gen has relied on Trimark for the last twenty years, and can rely on our team to make them a success for the next twenty.”

The design phase is already underway, with installation planned for the beginning of June. The process will be a long haul, more so than most: site construction just started this month, and is expected to be completed sometime in Q4 of 2022.

Selecting a SCADA system for a utility-scale generation site is no simple decision—especially when that site happens to be the largest PV+BESS site ever constructed. However, both Terra-Gen and Mortenson knew they could count on Trimark’s reputation for quality work, having worked with us on other large scale utility projects.
