The Ontario electricity market has presented a substantial financial opportunity for those who run a large industrial or commercial facility.
The December 2025 IESO Capacity Auction 2026 results have been made public, and they are truly historic. The value of Demand Response (DR) has skyrocketed to $171,319 per MW-year for the upcoming May 2026–April 2027 season—a startling 163% increase from the levels of the previous year.
For years, the Ontario Capacity Auction provided a steady, predictable revenue stream of approximately $60,000 to $75,000 per megawatt. Those days are over. Tightening supply and shifting grid dynamics have pushed prices to their highest levels since the auction’s inception.
| Obligation Period | Summer Clearing Price | Winter Clearing Price | Annual Value (per MW) |
|---|---|---|---|
| May 2026 – April 2027 | $645.24/day | $725.31/day | ~$171,319 |
For the first time ever, winter capacity is now more valuable than summer capacity, signaling a major shift in how the Independent Electricity System Operator (IESO) views grid reliability.
Why is the IESO suddenly willing to pay a 160% premium for your facility’s flexibility? Three major factors are driving this scarcity:
The Pickering “B” Nuclear Generating Station is slated to shut down for renovations by the end of 2026. More than 2,000 MW of baseload power, enough to power two million homes, will be removed from the grid as a result. The IESO is actively encouraging local, adaptable resources like yours to close this gap.
In the past, Ontario relied on imports during times of extreme strain from nearby states like New York and Quebec. However, import availability is decreasing as those areas deal with their own electrification issues. In order to guarantee that businesses in Ontario can make up the difference, the IESO is now required to pay a premium.
These days, Ontario is more than just a “summer-peaking” province. Winter demand is catching up to summer cooling peaks due to the quick uptake of EVs and electric heating (heat pumps). The grid is now under tremendous strain during the cold months, which explains why winter clearing prices skyrocketed to $725.31 per day.
Revenue is at an all-time high, but participation calls for a strategy. Here’s how to be eligible:
The 163% jump in DR revenue is a clear signal from the province: your facility is now a vital part of Ontario’s energy infrastructure. At $171,319 per MW, the business case for Demand Response has never been stronger. However, with record prices comes increased competition—and the IESO’s capacity targets are filling up fast.
