On April 16, 2010, TransCanada Power Marketing, Ltd. (“TransCanda”) filed suit in the U.S. District Court for the Central District of Massachusetts arguing that Massachusetts is unconstitutionally discriminating against out-of-state renewable energy producers. TransCanada purchases energy from generators and resells it to distribution companies and retail customers in the northeast United States. It is a U.S.-based subsidiary of TransCanada Corporation, a Canadian entity that, among other things, owns significant pieces of energy infrastructure in Canada and the United States, including power generation facilities. TransCanada’s suit challenges two Massachusetts programs that it claims benefit in-state economic interests while burdening out-of-state interests in violation of the U.S. Constitution’s Commerce Clause. It is seeking declaratory and injunctive relief as well as damages under 42 USC § 1983.
