General Motors Canada (GM) has announced the completion of a $28-million cogeneration investment at the GM St. Catharines, Ontario propulsion plant. The cogeneration project is expected to reduce net greenhouse gas emissions by approximately 70% while protecting the engine and transmission plant from rising electricity and carbon costs.
The St. Catharines plant makes engines and transmissions for GM factories across North America.
The 6.4-megawatt cogeneration project uses landfill gas delivered by pipeline from the nearby Walker landfill to power four 1.6 MW engines that will provide approximately 35% of the plant’s electrical power needs. Waste heat produced by the engines will be captured and used by the existing industrial boilers that provide heat and power throughout the plant.
Landfill gas, which otherwise would have been emitted as methane or flared to the environment, is now being received at the St. Catharines propulsion plant, and the engines are in the process of being commissioned. The cogeneration project will be running at full capacity by October 31, 2020.
“This cogeneration project demonstrates the power of local partnerships to deliver results that improve the bottom line, protect the environment and meet our sustainability targets,” said GM St. Catharines Plant Director Carolyne Watts in a statement.
GM says its St. Catharines cogeneration project is the first complete renewable landfill gas industrial cogeneration system in Ontario that uses renewable landfill gas from an offsite source.
GM has committed to power all of its global operations’ electricity needs with 100% renewable energy by 2040.
