OSHAWA, Ont.  —  General Motors Canada has completed a $28 million investment in cogeneration at its St. Catharines Propulsion plant.

The automaker forecasts cogeneration will reduce net greenhouse gas emissions by approximately 70% while buffering  the engine and transmission plant from rising electricity and carbon costs.

The 6.4-megawatt project uses renewable landfill gas delivered by pipeline from the nearby Walker landfill working with partner Integrated Gas Recovery Services (IGRS) to generate electricity from newly installed engines at the plant. GM will also recover the thermal energy typically considered waste to power and heat the plant.

Instead of using natural gas, the new engines are adapted to run on the renewable landfill gas delivered to the plant through a short pipeline. The landfill collects the gas instead of it being emitted as methane or flared into the environment.

The project involves partnerships with Alectra Utilities and the Ontario Centres of Excellence. It’s the first complete renewable landfill gas industrial cogeneration system in Ontario delivering 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.

The facility will be running at full capacity by Oct. 31.
