Responding to California’s Aliso Canyon gas supply constraints, the key power provider Southern California Edison (SCE) has decided to install a battery energy storage system from Current, powered by GE’s LM6000 Hybrid EGT package.
Faced with electricity shortages over the summer due to gas supply constraints, Southern California increasingly relied on wind and solar power, combined with electricity import. Rising intermittent power supply now makes the deployment of hybrid energy storage a necessity to keep the power grid in balance.
SCE hence has asked for a LM6000 Hybrid EGT s to be deployed at two SCE sites in the coming months. This solution will qualify for California’s Independent System Operator’s tariff for contingency reserve.
The LM6000 Hybrid EGT product integrates a 10 MW battery energy storage system from Current and an existing GE LM6000 aeroderivative gas turbine with control system upgrades. According to GE, the system will allow the turbine to operate in standby mode without using fuel and enable immediate response to changing energy dispatch needs.
Offers ancillary and grid support, the LM6000 Hybrid EGT can provide 50 MW of emission-free spinning reserve, flexible capacity, and peaking energy; 25 MW of high-quality regulation; and 10 MVA of reactive voltage support and primary frequency response when not online.
Eric Gebhardt, Chief Platforms & Operations Officer for Current called the solution a “truly a best-in-class joint effort by Southern California Edison, our partners at Wellhead Power Solutions, and multiple GE businesses.” GE now seeks to bring the same technology to other GE gas turbine customers around the world.
