The $171,000 Milestone: Why Ontario’s Demand Response Value Just Skyrocketed

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.

The Numbers: From $65k to $171k

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 the Surge? The “Perfect Storm” on the Grid

Why is the IESO suddenly willing to pay a 160% premium for your facility’s flexibility? Three major factors are driving this scarcity:

1. The Gap in Pickering

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.

2. Falling Imports & Supply Restrictions

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.

3. The Transition to “Dual-Peak” Stress

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.

Securing Your $171k Share of the IESO Capacity Auction 2026 results

Revenue is at an all-time high, but participation calls for a strategy. Here’s how to be eligible:

• Firstly, ask yourself, is it possible for your facility to reduce load by at least 100 kW over a four-hour period? Determine which non-essential procedures, HVAC modifications, or battery storage can be put on hold with two hours’ notice.
• Ensure your energy usage is steady enough to meet the IESO’s “High 15 of 20” baseline rules. If your load is too erratic, you may need a specialized strategy to avoid penalties.
• Since winter is now the “premium” season, ensure your facility can curtail load during the winter windows (6–11 AM and 4–9 PM) without compromising safety or critical production.
• Most industrial participants use an aggregator to manage the complex bidding and compliance. With prices this high, choosing a partner with low fees and high performance is critical to your net payout.

The Bottom Line

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.
