Ice Energy, NRG Energy deploy thermal energy storage in California

Ice Energy, provider of distributed ice battery storage solutions, in partnership with NRG Energy, will start installing Ice Bear 30 systems on commercial and industrial buildings in Orange County, California in a deal with Southern California Edison (SCE).

The companies will deliver up to 1,800 Ice Energy behind-the-meter ice batteries on a first-come, first-served basis.

“Our distributed ice batteries will solve local grid issues in Orange County while reducing CO2 emissions by up to 200,000 tons over the life of the project,” said Mike Hopkins, CEO of Ice Energy. “Orange County commercial and industrial customers that qualify for the program will get free use of Ice Bears, lowering electric bills and further extending the life of their HVAC systems.”

The Ice Bears will provide a total of up to 25.6 MW of peak storage capacity to SCE under 20-year power purchase agreements. The installations are part of SCE’s 250 MW energy storage procurement.

Ice Bears deliver peak capacity to the grid while reducing cooling costs for businesses. Freezing water when demand for power is low, Ice Bears use the energy stored in ice to cool buildings during peak hours without using power-intensive conventional AC compressors.

Air conditioning units that are equipped with Ice Bears consume up to 95 percent less electricity during peak hours, reducing air conditioning bills by up to 40 percent.

SCE customers not participating in this procurement program can take advantage of rebate programs, such as the Self-Generation Incentive Program (SGIP), to upgrade their air conditioning units and install Ice Bears with little or no upfront investment. SGIP provides rebates up to the total eligible project cost.
