The Portlands Energy Centre is a 550-megawatt natural gas electrical generating station in Toronto, Ontario.

It is located in the Port Lands area of the Toronto waterfront at 470 Unwin Avenue, adjacent to the site of the decommissioned Hearn Generating Station.

[3] The technical specifications of the plant in the original submission of the environmental review report (a less rigorous form of a full environmental assessment) to the Ministry of the Environment in November 2003 have been significantly altered.

This proposed configuration was capable of producing over 272,000 per hour of steam for district heating.

On September 18, 2006, TransCanada issued a press release[5] announcing that Portlands Energy Centre L.P. had signed a 20-year Accelerated Clean Energy Supply (ACES) contract with the Ontario Power Authority for the power output of the PEC.
