Excerpt:

Renewable energy sources, such as solar and wind, can be intermittent, but through energy storage technology, the energy can be used at any time, To test the benefits of energy storage, Alameda Municipal Power (AMP) is partnering with Amber Kinetics, a clean energy technology company. AMP serves 34,000 customers in the city of Alameda, California.

Amber Kinetics invented a technology that extends the duration and the efficiency of flywheel systems from minutes to four hours. Also, the system has no degradation or wear and tear over time unlike lithium ion energy storage systems, and it can be recycled after its 30-year life. As a result, the Kinetic Energy Storage System (KESS) can be used for a variety of utility-scale applications.

For the project, Amber Kinetics is connecting the KESS to AMP's electricity grid in Alameda Point. AMP’s partnership with Amber Kinetics allows the company to demonstrate the energy storage system on an active distribution system, according to the company.
