Terra-Gen and Mortenson have announced the full substantial completion of the Edwards & Sanborn Solar + Energy Storage project, the largest solar plus energy storage project in the United States. Mortenson was the full Engineering, Procurement, and Construction (EPC) contractor on both the solar and energy storage scopes for this vanguard project in the energy industry.

This project stretches over 4,600 acres and includes more than 1.9 million First Solar modules. In total, the project generates 875 MWdc of solar energy and has 3,287 megawatt-hours of energy storage with a total interconnection capacity of 1,300 megawatts. The project supplies power to the city of San Jose, Southern California Edison, Pacific Gas & Electric Co. and the Clean Power Alliance, and Starbucks, among others. A portion of the project is situated on the Edwards Air Force Base and was the largest public-private collaboration in U.S. Department of Defense history. The project uses LG Chem, Samsung, and BYD batteries.

• Fractal EMS provided full EMS controls for a BESS commissioned as a non-wires alternativeAUSTIN, Texas, Jan. 26, 2023 /PRNewswire/ — Fractal EMS Inc (Fractal EMS) and You.On have completed the integration of Brazil’s largest battery energy storage system (BESS). The BESS will discharge during high load periods and defer the cost of building an additional transmission line (non-wires alternative) by delivering power at the end of a congested line. Fractal EMS is equipment agnostic, You.On chose Kehua inverters paired with CATL liquid-cooled batteries. You.On was the system integrator and was selected through a competitive process. The project is located in Registro, Brazil and is owned by ISA CTEEP. The 30 MW / 60 MWh BESS will improve the resilience of the ISA owned transmission line and will reduce the need to import electricity from peaker plants. Fractal provided the controls, HMI, historian, networking and SCADA.Daniel Crotzer, CEO of Fractal EMS, said: “The energy storage market in Brazil represents a significant growth opportunity. Brazil is the world’s leader in renewable energy, battery storage could propel Brazil to 100% clean energy.”
