Current electricity contracts

As an important part of our mandate, the OPA has procured a portfolio of various generation technologies and capacities for the province of Ontario.

Information displayed, including capacity data, is accurate to the end of September 30, 2013.

Q3 2013 Update

As of September 30, 2013, the OPA held contracts for 22,368 megawatts (MW) of electricity supply generation based on average contract capacity.

Total contract capacity for Q3 2013 - 22,368 MW

The total capacity under contract included:

  • 8,170 MW of renewable non-hydroelectric;
  • 2,390 MW of renewable hydroelectric;
  • 8,809 MW of natural gas and other fuel sources; and,
  • 3,000 MW of nuclear.

Of this total capacity, 15,743 MW were in commercial operation or 70.4 percent of the OPA’s total contracted capacity. The remaining 6,678 MW of the OPA’s contracted capacity were in various stages of developmental status. See the chart below for details.

Within the total renewable generation capacity, about 1,710 MW were contracted with Aboriginal participation and 209 MW were contracted with community and municipal participation. This represented about 8.6 percent of the OPA’s total procured generation capacity.

We are committed to encouraging additional Aboriginal community participation in our renewable energy programs through the Aboriginal Energy Partnerships Program (AEPP). Efforts to improve community and municipal engagement in renewable energy development programs continue.

On this website, information on individual contracted facilities, both in commercial operation and in development, are grouped by technology type or fuel source, and can be found in the menu below the table or in the menu on the left side of this page.
