December 10 (SeeNews) - US renewables developer SunEdison Inc (NYSE:SUNE) has inked a 10-year deal with Ontario's Independent Electricity System Operator (IESO) to deliver 5 MW, or 20 MWh, of battery storage to the Canadian province.

SunEdison’s first commercial large scale grid-connected energy storage project will help the Ontario IESO analyse how storage can be utilised to smooth the power flow from wind and solar and defer or even avoid expensive system upgrades. The project has the potential to transform how it operates the power system, said Tim Derrick, SunEdison's general manager of Advanced Solutions.

The US company plans to begin construction work during the first half of 2017 and expects to complete the project later that year. It will use Imergy’s vanadium redox flow battery technology for the purpose of storing energy.

Upon completion, SunEdison Services will operate and maintain the system.
