Stem Installs 1 MW Energy Storage on Oahu

September 12, 2014 By Linda Hardesty

stem energy manageStem will deploy one MW of behind-the-meter energy storage in a demonstration project with Hawaiian Electric to support grid response services.

Stem will manage the energy storage system for commercial and industrial customers throughout Oahu. The aggregate portfolio of energy storage customers will provide additional grid capability during periods of variable solar generation and peak demand.

Stem’s technology also leverages the renewable forecasting and monitoring project that Hawaiian Electric currently operates. By participating, Stem customers will receive financial incentives to provide grid responsive power while supporting clean energy on the grid. The deployment will support the transformation of the Hawaii electric grid from one dependent primarily on fossil fuels to one that incorporates large amounts of solar and wind.

Hawaiian Electric and Stem will work together to identify and enlist participation of commercial and industrial customers with rooftop solar systems. All installations are expected to be completed by March 2015.

The program is supported by $1 million in grant funding from Hawaii’s Energy Excelerator, which was created to commercialize game-changing energy technologies.
