GUELPH, Ontario, Canada, Aug. 31, 2015 -- Canadian Solar Inc. (the "Company", or "Canadian Solar") (NASDAQ: CSIQ), one of the world's largest solar power companies, today announced that its wholly owned subsidiary, Recurrent Energy, one of North America's largest solar project developers, signed an agreement with Southern Power, a subsidiary of Southern Company (NYSE: SO). Southern Power will acquire a controlling interest in the 200-megawatt (MW) Tranquillity Solar Power Project in California. The project, developed by Recurrent Energy, is currently under construction.

Under the terms of the agreement, Southern Power will acquire approximately 51% of the solar generation project. Canadian Solar will retain 49% ownership and contribute its share of the investment required to complete the construction of the project, which the Company has fully financed through a construction and back-leveraged loan facility with a syndicate of six banks.

The Tranquillity project, covering an area of 1,900 acres in Fresno County, is expected to reach commercial operation in the fourth quarter of 2016 with Signal Energy Constructors as the provider of engineering, procurement, and construction services.
