Siemens Energy wins its first black-start battery storage project for power generation in the U.S.

Traditional emergency back-up systems run on diesel generators or small, fossil fuel industrial turbines.  By contrast, the BESS-based black-start system operates in a carbon-neutral way to start one of the plant’s four combustion turbine generator units.  In addition to the BESS, the project will involve transformers to increase voltage, switch gear to integrate the BESS into the broader Marsh Landing system, electrical, civil and structural engineering and control system modifications.  
“Battery storage systems like this one are capable of fully restarting power on a highly expedited basis,” said Laura Anderson, senior vice president, Controls and Digitalization for Siemens Energy.  “We are excited to lead this project at Marsh Landing because it will not only help to restore power quickly in the event of an outage, but it will reduce emissions over traditional back-up systems.  It will also improve grid reliability in the Bay Area.”
The Marsh Landing Generating Station is a four-unit simple-cycle plant and was one of Siemens Energy’s first “Flex-Power” plants, which are capable of fast starts that minimize emissions while ramping up to full power in only 12 minutes.  It entered commercial operation in 2013 and can provide 720 megawatts of electricity to the California grid, enough to serve up to 650,000 homes.  Siemens Energy supplied the four gas turbines, four generators, the SPPA-T3000 distributed control system and auxiliary and secondary systems for the plant.
 “Battery storage will play an increasingly important role in both securing the power grid and enabling renewable energy generation,” said Chad Plotkin, chief financial officer at Clearway Energy. “We are excited to work with Siemens Energy on this strategically important project at Marsh Landing to deliver long-term grid resilience and continue to act as a source of reliable power supply to the Bay Area.”
Work on the project has already begun, with the project scheduled to commence in early-summer 2021.
