Reliability Outlook Sector Participants

Fall Reliability Outlook released

The fall edition of the IESO’s Reliability Outlook presents Ontario’s demand forecast, as well as the adequacy of generation and transmission resources over the next 18 months.

According to the latest outlook, Ontario is well-positioned to meet the demand for electricity for the 18-month forecast period – it is expected that any shortfalls arising during this time will be managed through the rescheduling of outages.

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.
