NRG Energy and Ice Energy have announced a partnership deal designed to reduce peak energy demand through a novel energy storage technology.
With 20 year long-term contracts in place to provide 25.6 MW of behind-the-meter energy storage, the companies will use Ice Energy’s proprietary Ice Bear technology for Southern California Edison (SCE).
Subject to final approval from the California Public Utilities Commission, approximately 1800 Ice Bear units will be installed in Orange County beginning in early 2016.
Attaching to one or more standard 5-20 ton rooftop commercial AC units, the Ice Bear freezes water at night when demand for power is low and capacity is abundant. It then uses this stored ice during the day to provide cooling instead of using power-intensive AC compressors. Each Ice Bear can reduce CO2 emissions by up to four tons per year, the company claims.
Mike Hopkins, CEO of Ice Energy, commented: ‘Energy storage, particularly the distributed and efficient storage capacity provided by our Ice Bears, reduces reliance on fossil fuels and helps better integrate renewable energy sources into a smarter electric grid.’
Financial terms of the agreement were not disclosed.
