The St. Clair Energy Centre is a 570 MW natural gas fuelled combined cycle project under construction in St. Clair Township near Sarnia, Ontario. The project’s output will be sold into the power market administered by the Independent Electricity System Operator pursuant to a clean energy supply contract with the Ontario Power Authority. The St. Clair Energy Centre was selected following the Ontario Ministry of Energy's 2004 open and competitive RFP (request for proposal) process for new, clean energy in Ontario.

The project is comprised of two GE 7FA combustion turbines configured in a combined cycle with two heat recovery steam generators and two steam turbines. The St. Clair Energy Centre was the subject of extensive environmental analysis in accordance with the Ministry of the Environment’s guidelines.  The environmental assessment documents are available upon request.  The project is expected to commence commercial operations by the end of 2008.
