OSHAWA, Ont. — General Motors of Canada is planning to reduce its use of electricity at its Ontario engine plant and lower carbon emissions by harnessing landfill gas.

The Oshawa, Ont.-based automaker is proposing to build a 6.4 megawatt co-generation plant that will use landfill gas as fuel and recover thermal energy to power and heat the St. Catharines Propulsion Plant.

The project is a partnership with Alectra Utilities in Mississauga, which serves municipalities north and west of Toronto; Integrated Gas Recovery Services, a Thorold company that facilitates the use of landfill gas; and the TargetGHG program funded by the Ontario Ministry of Research, Innovation and Science and administered by Ontario Centres of Excellence (OCE).

GM says the proposed project will reduce net greenhouse gas emissions 77% while lowering its electrical costs. When it’s online in mid-2019, this clean energy will power approximately 32% of the St. Catharines’ plant, the most of any of GM’s global population operations worldwide.

The project represents Ontario’s first complete landfill gas co-generation system for industrial users that delivers the gas via pipeline from an offsite landfill source.

The automaker has committed to power all of its global operations’ electricity with 100% renewable energy by 2050.

TargetGHG brings together large industries, cleantech companies and research consortiums to develop new technologies that help lower greenhouse gas emissions.
