This natural gas-fired power plant cost 730 million and is state of the art. It provides clean, safe, efficient and reliable energy. The Doors Open tour was very informative as our knowledgable guide explained how efficient this plant was compared to the closed coal power plant next door. It provides up to 550 megawatts of power, enough to serve approximately 500,000 homes in central Toronto. It is fueled by natural gas which is one of the most efficient and cleanest fuels for generating electricity.
Portlands Energy Centre is a combined cycle power plant, where natural gas is burned to produce electricity in two ways (or cycles). In Cycle 1, natural gas is piped into the plant and combusted to turn a gas turbine, producing the first cycle of energy. In Cycle 2, the heat created by burning gas is captured to produce steam which turns a steam turbine, producing the second cycle of energy. Adding the second cycle increases the amount of electricity produced by the natural gas. This translates into lower fuel usage and lower emissions for every kilowatt of electricity produced.
The powerhouse building is 37 metres tall and covers 12,561 square metres. It has two independent but equally rated identical combined cycle, cogeneration power plant systems. It is environment friendly and they even have bee hives on the property.
