Ontario's First Local Electricity Market Corporate IESO

Ontario's First Local Electricity Market

In an effort to save costs and find affordable alternatives to building new transmission infrastructure, Ontario’s first ever local electricity market is launching in York Region.

The local electricity market will allow resources like solar panels, energy storage, and consumers capable of reducing their electricity use to compete to be available during periods of high demand. Leveraging existing local resources could help avoid the need to invest in new transmission lines and stations, while competition will drive down costs.
