Renewable energy development company SunEdison has signed a 10-year agreement to provide 5MW of vanadium redox flow battery storage in Canada.
The US company will supply the 20 MW/h battery storage to Ontario following the deal with Ontario’s Independent Electricity System Operator (IESO).
The project will use flow battery technology leader Imergy’s vanadium redox flow battery technology.
This project will be SunEdison’s first commercial large scale grid-connected energy storage project, and is one of the first commercial applications of flow batteries in Canada.
The IESO will be used to test the ability of batteries to smooth the flow of renewable energy from wind and solar and shape the future of its grid.
Tim Derrick, SunEdison’s general manager of Advanced Solutions, said: “Batteries can be used to reduce grid congestion, smooth out power flow from solar and wind sources, and may help the IESO defer or avoid expensive upgrades to the grid.”
SunEdison plans to start construction of the project during the first half of 2017, with completion targeted for later that year.
