The two-phase project will first install a battery energy storage system from Current, followed by upgrades to a GE LM6000 gas turbine to integrate the two systems.
The combined system, known as the LM6000 Hybrid EGT, will be deployed at two SCE sites in the near future.
In a press release, GE said the system was developed in response to changing regulations and grid requirements in the wake of California’s Aliso Canyon energy crisis earlier this year.
“GE’s new LM6000 Hybrid EGT product fits well with SCE's objective of providing cost–effective, innovative solutions that enhance grid reliability, flexibility, and fast response for our customers,” said Phil Herrington, Vice President of Generation for Southern California Edison.
GE’s Power Services and Current businesses worked to develop the joint solution in a competitive offer in collaboration with Wellhead Power Solutions, LLC.
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 provided by GE’s Power Services. The system will allow the turbine to operate in standby mode without using fuel and enable immediate response to changing energy dispatch needs.
By eliminating the need to constantly run the turbines at minimum loads to maintain spinning reserves, the LM6000 Hybrid EGT will save fuel, reduce maintenance costs and cut down on carbon emissions.
The LM6000 Hybrid EGT offers ancillary and grid support at a lower cost and smaller carbon footprint than traditional resources, plus it 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.
