Investing in Grid Innovation

The IESO’s Grid Innovation Fund advances innovative opportunities to achieve electricity bill savings for Ontario ratepayers by funding projects that either enable customers to better manage their energy consumption or that reduce the costs associated with maintaining the reliable operation of the province's grid.

Applications for projects designed to pilot, and in some cases develop, innovative technologies, practices, services, programs and research are being accepted from March 1 to March 31, 2019.
