GE and Southern California Edison (SCE) have unveiled the world’s first battery-gas turbine hybrid system in Norwalk, California. This system, called the LM6000 Hybrid Electric Gas Turbine (Hybrid EGT) supports SCE’s increasing renewable energy capacity by providing quick start, fast ramping capabilities to balance variable energy supply and demand, especially during the evening peak. The unit integrates a 10 MW, 4,3 MWh battery energy storage system capable of providing instant power on demand using GE’s 50 MW LM6000 aero-derivative gas turbine. The Hybrid EGT uses a control system which seamlessly blends output between the battery and the gas turbine, providing enough time for the gas turbine to start and reach its rated power output. The system does not burn fuel or consume water in stand-by mode. This provides enhanced flexibility, reduces greenhouse gas emissions and air pollution by 60% and saves about 8-million l of water annually while increasing the life of the equipment.
