GE to install hybrid gas-turbine and battery storage combination in two SCE locations

On October 4, GE and Southern California Edison announced the utility would install a battery storage and gas turbine hybrid in two locations.

The two-project solution first calls for installation of a battery energy storage system from Current, a GE subsidiary, followed by upgrades to a GE LM6000 gas turbine to integrate the two systems.

The LM6000 Hybrid EGT, which is scheduled to be deployed at two SCE sites in the coming months, was developed in response to changing regulations and grid requirements in the wake of California’s Aliso Canyon energy crisis earlier this year and will ultimately support increasing renewable energy capacity on the California grid.

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 greenhouse gas emissions.

The resulting power generator, which will qualify for California’s Independent System Operator’s tariff for contingency reserve, answers a critical need for Southern California, where regulations on natural gas usage and storage are changing in the wake of the state’s Aliso Canyon energy crisis earlier this year.

GE’s Power Services and Current businesses worked to develop the joint solution in a competitive offer in collaboration with Wellhead Power Solutions, LLC.

Phil Herrington, Vice President of Generation for Southern California Edison noted:

“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.”

Eric Gebhardt, Chief Platforms & Operations Officer for Current observed: “This was truly a best-in-class joint effort by Southern California Edison, our partners at Wellhead Power Solutions, and multiple GE businesses to enhance our technology and add Current’s battery storage system to existing GE turbines. As a team, we worked together to quickly provide a complete scope of the challenge and find a solution in a very short time frame. Now we can bring this same technology to other GE gas turbine customers around the world.”

Paul McElhinney, President and CEO of GE’s Power Services commented: “We are excited to launch this innovative hybrid solution to provide immediate power, increase the flexibility of our gas turbines, leverage new software controls solutions and increase customer competitiveness. With our total plant solutions capabilities, we are able to help California increase its grid efficiency and help SCE deliver more affordable energy in a changing marketplace.”
