The Hornepayne Power Cogeneration Plant was completed in 2014.
The Cogeneration Plant is a biomass fuel-fired cogeneration facility located adjacent to the lumber manufacturing facilities of the Hornpayne Lumber Company. The facility has a total nameplate capacity of 15.0 MW, of which 8.0 MW is contracted to the Ontario Power Authority. In addition to electricity production, the plant provides steam to the mill for lumber drying and space heating purposes. The plant consumes 175,000 to 200,000 tonnes of sawmill wood by-products annually.
Major equipment for the facility consists of an inclined grate-fired boiler burning biomass to produce high pressure steam that is fed into a single extraction/condensing steam turbine generator.
We harvest a mix of trees, approximately 50% of which is processed into manufactured lumber. The other 50% becomes byproduct residuals and waste streams that are collectively called “residuals” and have significant value in their energy potential. Residuals include in-forest fibre from the harvesting process — tree tops, branches, low grade logs damaged by insects or disease, hog fuel (bark), shavings, sawdust, and trim blocks from the lumber manufacturing process.
Sawmill residuals and in-forest fibre in Ontario are required to be either utilized or burnt as a waste management measure, to reduce fire hazard and to avoid the risk of disease and pest infestation. Finding opportunities to use this former waste material contributes to Ontario’s health, greenhouse gas reduction, and economic value objectives.
In Ontario, forests are managed provincially. 95% of provincial lands are publicly owned and managed through a comprehensive regulatory framework for land and resource use planning, which includes direction for the establishment of protected areas and operational forest planning. Our forest regulations are rated among the most stringent in the world and our fibre sourcing and forest products are certified sustainable through the independent and globally recognized Sustainable Forest Initiative.
Feedstock or fuel for the Becker Power Plant is supplied by both sawmill operations, and may be a blend of a variety of residual by-products from forestry and sawmill operations, including shavings, sawdust, trim blocks and hog fuel (bark).
While the power plant primarily uses hog fuel and dry shavings from our sawmill facilities, Hornepayne Power will continue to look to the most cost-efficient supply for operation. This may include lower-value residuals from nearby sawmill operations and potentially in-forest residues (tree tops, branches, and low-grade logs damaged by insects or disease,) left behind in the harvesting process.
