Gain Fuel Canada*/C.A.T. Inc.

Project Background:

C.A.T. Inc. contracted U.S. Venture Gain Fuel Canada to design, build, own and operate a GAIN Clean Fuel compressed natural gas (CNG) refuelling station in Coteau-du-Lac, Quebec to serve 100 CNG sleeper tractors in its delivery fleet. Together the two companies decided that the project should include additional retail fuelling lanes for third party fleets.

Challenges and Solutions:

Commitments to commercial clients required a fast-track approach for the project’s design and permitting. Change Energy’s team (Change Energy Services, Change Energy West, GHD) was contracted by Gain Fuel Canada* to deliver the full scope of engineering, permits and approvals for the project.

The facility’s compression system needed to serve 24/7 operations for the trucking fleet requirements. Change Energy West worked with Gain Fuel Canada*/C.A.T. and equipment manufacturers to design a system that would operate automatically with minimal maintenance and repairs.
