Peak Notification

A tailored solution for Class A load customers in Ontario under the Industrial Conservation Initiative (ICI), helping businesses navigate energy costs and manage demand during critical peak periods.

Ontario daily peak demand, 2025, with the five coincident peak days marked Daily peak Ontario demand through 2025. The five highest days, which set Class A Global Adjustment, are marked. They spanned 651 MW, and the sixth-highest day fell short by only 148 MW. 15,000 20,000 25,000 MW Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 24,862 MW
Ontario daily peak demand through 2025. The five days that set Class A Global Adjustment — Jun 23, Jun 24, Jul 24, Jul 28, Aug 11 — are marked in green, and the band spans them; consecutive dates overlap at this scale. The hollow marker is the sixth-highest day, which did not count.

In the complex and ever-changing landscape of energy management, we offer an innovative approach through our Peak Notification Service. With many years of proven success, we specialize in accurately forecasting Ontario’s top five peak demand events each year.

We provide advanced notifications when there is a potential occurrence of a top five peak demand event. Customers benefit from our expertise in the Ontario energy market. Our team delivers actionable analysis and dedicated support, empowering customers to make informed energy decisions with confidence.

Why the timing is hard

Under the ICI, a consumer’s Global Adjustment charge for the following year is set by its demand during the five coincident peak hours of the base period — the highest hour of each day, ranked, with the top five counting. Only one hour per day can count, so the five peaks land on five separate days scattered across the summer.

The margins are fine. The five days that counted in 2025 spanned 651 MW, under 3%. The sixth-highest day missed the cut by 148 MW: roughly half a percent, and worth nothing at all.

In the moment there is no way to tell those apart. Curtail on every candidate and you disrupt operations all summer; curtail on too few and you carry the Global Adjustment charge for a year.
