Trillium Power Wind 1 (TPW1) is a proposed 450 to 500 megawatt (MW) far-offshore wind farm in the Canadian waters of northeastern Lake Ontario at least 17 to 28 km from the nearest mainland. This renewable energy project is being developed by Trillium Power Wind Corporation, a privately held, Canadian-owned company headquartered in Toronto, Ontario. The project was placed in moratorium by the Ontario government on February 11, 2011 at exactly the same hour that Trillium Power was completing a $26 Million financing. A larger follow on equity investment of $400 Million was in discussion with two large global pension funds at the time. Had it not been placed in abeyance, TPW1 would have been the first offshore wind farm built in the Great Lakes. Recently, on January 19, 2023, the Ontario Court of Appeal heard an appeal by Trillium Power, focusing on evidence provided by Trillium Power of spoliation in an ongoing litigation by the Ontario Government.
