Wood processing

La Granaudière at Saint-Michel-des-Saints


Electrical and control systems for the new wood pellet production plant at Saint-Michel-des-Saints

The Granaudière project involved the construction of an integrated modern production plant covering all phases of the process from log intake to shipping of high-energy pellets. The plant has a capacity of 200,000 tons and mainly exports to Europe.

Project description

Wood pellets have a high energy content. Made from forest biomass (sorting residues, pulpwood, and wood scraps), which is a renewable resource, this green energy fuel is in demand world-wide by industries and power plants. The production process involves increasing the wood fibre density while reducing its moisture content. The Granaudière project has involved the construction of an integrated modern plant covering all phases of the process from log intake to shipping of high-energy pellets. The plant has a capacity of 200,000 tons per year, which is mostly exported to Europe. 

Our involvement – Process areas covered 

In this project, we were involved in the electrical and control aspects of the following process areas:

  • Log receiving.
  • Preparation (debarking, cut to length).
  • Chip production.
  • Fibre mixing.
  • Bark management.
  • Boiler feed.
  • Fibre drying (interface only).
  • Fibre conditioning.
  • Pelletizing.
  • Storage.
  • Filling of transport trucks.
  • Fire extinction system (connection and interface).

Our contributions to the project 

Management at La Granaudière entrusted to us the electrical and control portions of their brand-new plant at St-Michel-des-Saints. We took responsibility for the service entrance and distribution as well as full automation of the system. The following list presents the services included in this mandate. 

  • Electrical engineering (power, control, and networking).
  • Fabrication of power, control, and network panels.
  • Electrical installation (35KV feeder, 4.2KV and 600V distribution, motor feeders, connections to control systems, instrumentation, and networks).
  • Programming of PLCs and operator interface systems.
  • Integration with the controllers of certain stand-alone equipment.
  • Start-up and production monitoring.
  • Optimization.
