Ontario's average wholesale price by month, 2025. HOEP settled wholesale bills until the market renewed on 1 May 2025; the Ontario Price has settled them since, and May is partial because the new series begins on the 3rd. Verifying an invoice across that boundary means checking two different prices.

With a focus on the challenges presented by an unpredictable market, we offer wholesale settlement services and invoice-monitoring strategies to assist market participants with the verification of their IESO invoices.

Renewables Settlement and Consulting

Our in-depth knowledge of the Ontario energy market provides customers with a wide range of service offerings. Our flexible solutions include settlement audits, customized reporting, and detailed consumption and cost analysis.

We currently assist Ontario wind generators with managing their revenues by performing daily data retrieval, web-posting of reports, and verification of all IESO data.

For customers that have internal generation capabilities or are exploring new installations, we provide analysis to help maximize those assets and support sound business decisions. We will start by assisting your organization with the initial IESO registration.

If you require assistance in understanding the complexities of Ontario’s energy market and their impact on your generation facility, we can help.
