Grid Innovation Fund Get Involved

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.

Market Renewal Sector Participants

MRP High-Level Designs Released

After extensive stakeholder consultation, the IESO has released high-level designs for the Market Renewal Program’s day-ahead market (DAM) and enhanced real-time unit commitment  (ERUC) initiatives.

The DAM will provide greater operational and financial certainty, while lowering the cost of producing electricity. The ERUC will help ensure the most cost-effective set of resources are used to meet demand as it changes from day-ahead to real-time. Feedback on both designs is due February 28, 2019.
