These two plants use Canadian Solar’sCS6X-305P modules, and are part of a sales agreement whereby Canadian Solar will sell a total of three utility-scale solar power plants from its Ontario pipeline to RET.

DiscoveryLight is located in the town of Beaverton, while FotoLight is located in the Township of Prince Edward County. The electricity generated by these two power plants, both currently in commercial operation, will be sold to Hydro One under a 20-year Ontario Power Authority feed-in-tariff contract.

Canadian Solar provided turnkey engineering, procurement and construction services, and will also provide operations and maintenance services. A third 10 MW AC power plant (“CityLights”) is scheduled to begin commercial operation in the first quarter of 2015 with closing occurring post commercial operation.
