Manufacturer: Beacon Power

Beacon Power is a pioneer and technology leader in the design, development, and commercial deployment of grid-scale flywheel energy storage. They are known for their world-renowned Carbon Fiber Flywheel. Beacon’s flywheel is essentially a mechanical battery that stores kinetic energy in a rotating mass. Advanced power electronics and a motor/generator convert that kinetic energy to electric energy, making it instantly available when needed. Their patented flywheel systems are modular and can be configured to meet the power capacity demands of a variety of applications, from 100 kW to multi-MW systems.

Beacon Power is the global leader in the development and commercialization of fast response flywheel-based energy storage systems, offering proven solutions at the utility-scale for power grid efficiency, frequency regulation, grid reliability, renewable power integration and other ancillary services. Beacon’s proprietary designs are at the heart of a cost-effective and durable energy storage device that enables grids to operate more reliably.

Beacon Power is committed to providing utilities and system operators the best flywheel-based energy storage resources to help maintain a reliable, cost-effective and stable power grid. Beacon currently operates three commercial flywheel plants ranging in capacity up to 20 MW in three different U.S. markets and their flywheel system has delivered over 7 million operating hours. The company’s headquarters and manufacturing facility are in Tyngsboro, Massachusetts.
