A company that is commercializing new technology for storing energy has won a contract to deliver a two Megawatts flywheel energy storage facility for Ontario's independent electricity system operator.

For NRStor Inc. it will be the first commercial test in Canada of flywheel technology, a mechanical battery that stores electricity as kinetic motion in a spinning rotor levitated on magnetic bearings.

NRStor sees a big future in energy storage, as a way for the manager of an electrical grid to match supply and demand, says Annette Verschuren, chair and CEO of the company.

"There is a lot of energy coming in off the grid and the grid needs to manage it," said Verschuren in an interview with CBC's The Lang & O'Leary Exchange.
