Fact Sheet #19 - Meeting Toronto's Electricity Supply Needs: A comparison of the Portlands Energy Centre and the Toronto Waterfront Clean Energy Centre Toronto is highly reliant on large centralized electricity supply sources outside of the city, such as the Pickering and Darlington nuclear stations and the giant Nanticoke coal-fired station on Lake Erie. However, efforts are underway to locate new generation capacity within the city, while also improving overall energy efficiency. There are two proposals to build new generation facilities on the eastern waterfront: the Portlands Energy Centre and the Toronto Waterfront Clean Energy Centre.
