Edwards Sanborn

SBES

Project Type: 810MW AC Hybrid Site (Solar + BESS) comprised of seven separate resouces
Location: Mojave, CA
Client/EPC: Terra-Gen

Trimark delivered and commissioned plant controls for all resources in Edwards-Sanborn Phase 1A – the world’s largest capacity solar-plus-storage project. The seven resources included in the Mojave-based Phase 1A have a nameplate capacity of 810 MW (LGIA limit of 634 MW).

Each resource is managed by Trimark’s intelligent power plant controller (PPC), a utility-scale SCADA system designed to optimize the profitability of photovoltaic (PV) and battery energy storage system (BESS) resources that participate in California’s open energy markets.

To maximize output and support stable power at the point of deliver, each resource’s PPC considers the losses introduced by any of the five hybrid (PV+BESS) and/or two BESS resources. Trimark’s Dynamic Loss Compensator (DLC) calculates energy losses for each resource and applies the value as a control point to the affiliated PPC. Each PPC then adjusts generation, charge and discharge decisions in real time to ensure that its resource delivers the maximum power allowed by the LGIA or the ISO’s target value.
