Suncor Energy doubles production capacity at St. Clair Ethanol Plant

SARNIA, ONTARIO--(Marketwire - March 25, 2011) - Suncor Energy today recognized the completed expansion of its St. Clair Ethanol Plant at an event held on site in the Sarnia–Lambton region. The completion of this project has since doubled the plant's production capacity from 200 to 400 million litres of ethanol per year, confirming it as Canada's largest biofuel production facility.

"The St. Clair Ethanol Plant is the platform for growth of Suncor's biofuels portfolio, and our successful expansion of the plant's capacity not only reinforces our commitment to increasing renewable energy options in Canada but builds on the strength of our relationship with the St. Clair Township and the Sarnia-Lambton Region," said Jim Provias, vice-president, Renewable Energy.

Government representatives joined Suncor executives and local stakeholders at the event recognizing the completion of the $120-million expansion project. The expansion created approximately 250 construction jobs and the plant now supports 63 full time office and operating staff. The St. Clair base plant opened in June 2006.

Suncor is one of the largest players in renewable energy in Canada. The expanded St. Clair Ethanol Plant, along with Suncor's investment in four operating wind power projects across Canada, is expected to displace the equivalent of nearly one million tonnes of carbon dioxide per year – the equivalent of the annual tailpipe emissions of approximately 200,000 cars. Two additional Suncor wind power projects are currently under construction and scheduled for completion in 2011. Construction on the 88 megawatt (MW) Wintering Hills wind power project in Southern Alberta, which began in the second half of 2010, is expected to be completed by the end of 2011. At peak operation the project is expected to generate enough electricity to power approximately 35,000 Alberta homes and displace 200,000 tonnes of carbon dioxide (CO2) per year. In addition, a 20 MW project is currently under construction west of Thamesville, Ontario and is expected to be completed by mid 2011.
