About St. Clair Energy Centre

The St. Clair Energy Centre is a 584-megawatt combined-cycle natural gas turbine generation facility. The Energy Centre is located in St. Clair Township, in the province of Ontario, Canada and began operations in 2009. Power generated from the facility is transported to the provincial electrical transmission network through an onsite transformer station, where it is eventually delivered and utilized by consumers.

St. Clair Energy Centre is proposing modernization upgrades and an expansion of the facility. The upgrades and expansion would an additional 180 megawatts of electricity generation capacity and assist the province of Ontario’s emerging electricity system needs.

Need for Electrical Generation

According to the Independent Electricity System Operator (IESO), which is responsible for overseeing Ontario’s power system, the province is entering a period of increasing demand for electricity, driven by more consumer usage, and the retirement of existing power plants.

To accommodate growing demand for electricity, the IESO is undertaking a procurement process to acquire additional electrical generation capacity from both new power plants and the expansion of eligible existing ones. Two procurement streams are being undertaken including:

Expedited Long-Term Request for Proposal (E-LT1 RFP), which require the successful facility to be operational as early as 2025 and
Long-Term Request for Proposal (LT1 RFP), which requires the successful facility to be operational in 2027, or earlier.

The E-LT1 RFP is intended to competitively procure up to 1,500 MW of electrical capacity, of which 900 megawatts (MW) are targeted to be procured from electricity storage facilities and 600 MW from resources other than electricity storage facilities. For the LT1 RFP, the IESO is expected to procure approximately 2,500 MW of electricity reliability services from new build and eligible expansion electricity resources.
