Sarnia Photovoltaic Power Plant near Sarnia, Ontario, is Canada's largest photovoltaic plant with an installed capacity of 97 MW<sub>P</sub> (80 MW<sub>AC</sub>).
In 2009, Ontario introduced a feed-in tariff renewable energy payments program paying up to CDN 44.3 cents per kW÷h for large ground arrays such as the Sarnia plant. This makes Ontario's one of the top feed in tariff programs in the world.
Phase I (for 20 MW) was completed in December 2009. Phase II (60 MW) was completed in September 2010 at a cost of C$300 million. The project was developed by Enbridge.
First Solar developed, engineered, and constructed the facility, and it will operate the Sarnia Solar Project for Enbridge under a long-term contract. Enbridge will sell the power output of the facility to the Ontario Power Authority pursuant to 20-year power purchase agreements under the terms of the Ontario government's Renewable Energy Standard Offer Program.
The plant covers and contains about of modules, which is about 1.3 million thin-film panels. At the completion of Phase II it was the largest solar power station in the world, a title it held until the 2011 opening of Huanghe Hydropower Golmud Solar Park in China. The expected annual energy yield is about 120,000 MW÷h, which if produced in a coal-fired plant, would require emission of 39,000 tonnes of CO<sub>2</sub>.
