Biomass Power Plant

The Williams Lake station is the largest biomass power plant in North America. The overall plant configuration is based on a conventional power cycle used in typical utility thermal plants.

The major equipment includes a boiler to produce steam, a steam turbine to extract the thermal energy for conversion to electric power, a condenser to convert the exhaust steam to water, a high voltage step up transformer, a solid fuel handling system, an ash removal/handling system and other steam cycle auxiliary equipment.

This state-of-the-art facility is also equipped with combustion and emission controls, including multiple cyclones and an electrostatic precipitator. The plant has been designed to surpass the air emissions permit levels that are already five times tighter than existing regulations for wood-waste-fired boilers.

The electricity produced by the plant is sold at fixed terms under a long-term contract to BC Hydro. The terms of the power purchase contract extend to 2018.

When the plant was originally constructed, it provided a solution to a long-standing air quality problem in the area. Utilizing wood waste from local sawmills enabled those mills to close their beehive burners, which in turn reduced particulate emissions in the area by over 90%. The Williams Lake plant solves a major solid waste disposal problem for local sawmills, and improves their competitiveness and stability within the local economy.
