The Portlands Energy Centre is a 550-megawatt natural gas electrical generating station that is nearing completion on the Toronto waterfront at 440 Unwin Avenue – the site of the decommissioned Hearn Generating Station .

[edit] Corporate Support

The Portlands Energy Centre is being funded by a joint partnership between Ontario Power Generation and TransCanada Energy.

[edit] Technical specifications of the proposed plant

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 Ontario Ministry of the Environment in November 2003 have been significantly altered. This was due to the government instructing Ontario Power Generation to stop participating in projects which use more environmentally acceptable generations systems, such as co-generation [1]. Originally, the plant was described as two identical 275 MW power train systems, each comprising a 175 MW GE 7FA gas turbine generator, and other equipment. This proposed configuration was capable of producing over 272,000 kilograms per hour of steam for district heating. This design would, according to a PEC newsletter, allow for the efficiency of the plant to be “about 55% compared to 35% for a typical fossil power plant” There were also plans to include “Canada’s largest solar array” capable of producing “hundreds of kilowatts” though no actual specification seems to have ever been given[citation needed].

[edit] Local Opposition

[edit] Environmental Issues

The original design met with some community resistance and many local residents, all local politicians and a number of significant City of Toronto departments including the Works Department and the Board of Health. These groups called for a full Environmental Assessment (EA) as a way to resolve some of the technical and health related issues with the plant. The Ontario Liberal Government denied a full EA. Over time, the plan was altered significantly in a way that reduced the efficiency and aesthetic virtues of the plant. In November 2004, the proponents hosted a meeting to tell the community that the generation of steam for district heating was no longer going to happen and that the solar panels were no longer going to be included. It was also noted that the attempts to make the exterior of the plant aesthetically pleasing had been dropped in favour of a shed type design[citation needed].

[edit] Location Issues

The plant was met with considerable local opposition, since it was to be sited on the Waterfront, which is currently undergoing a revitalization process, and has been striving to be a “world leader in sustainable design” (according to the Corporation Chair, Robert Fung). The Ontario Liberal Government decided that, despite the opposition of local citizens, their elected representatives and the City of Toronto, the project would be allowed to move forward without a full Environmental Assessment. The Toronto Waterfront Revitalization Corporation played a more neutral role, offering criticism of the plant but falling short of calling on one of its political masters to change plans.

[edit] Power Purchase Agreement, Timing and Capital Costs

On September 18, 2006, TransCanada issued a press release [2] 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.

The plant is scheduled to start delivering 340 MW of power to the City of Toronto in June 2008 in single-cycle operation and ramp up to full output at 550 MW by the second-quarter 2009[3]. Total capital costs are expected to reach $730MM.
