Securing Long-Term, Reliable Power in Ontario

Province Negotiates New Contract with Ottawa Generator

Ontario has negotiated a new agreement between the Ontario Power Authority (OPA) and TransAlta Corporation to secure electricity production for the next 20 years.

The contract will guarantee TransAlta's natural gas-fired cogeneration facility in Ottawa will provide electricity to the provincial grid and reduce the need to build new generation. Locally, the plant provides heating and cooling to the Ottawa Health Sciences Centre, which includes the National Defence Medical Centre and the Rideau Veterans Health Centre.

Ontario's new structure for negotiating rates for thermal non-utility generators will result in cost and reliability benefits for Ontario's electricity customers. The TransAlta plant is one of the first contracts negotiated under the new structure.

Building a reliable electricity system is part of the government's economic plan that is creating jobs for today and tomorrow. The comprehensive plan and its six priorities focus on Ontario's greatest strengths - its people and strategic partnerships.

Quick Facts

  • Non-utility generators are independent electricity generating facilities that supply electricity to the Ontario grid.
  • In 2012, non-utility generators produced 9.8 TWh of power, making up 6.5 per cent of the province’s electricity demand.
  • TransAlta’s 74 MW gas-fired Ottawa cogeneration plant began operating under its new OPA contract on January 1, 2014.
  • The plant also supplies electricity to the provincial grid under its long-term contract with the OPA.

“Non-Utility Generators have a role to play in the province's safe, clean, and reliable electricity supply. Renegotiating only the contracts that will provide cost and reliability benefits to Ontario consumers will be prudent in meeting the changing demand projections from across the province.”
