West Fraser Timber Company will generate 13 MW of power for its British Columbia plant and the province as a whole, using wood chips converted to biomass fuel.
The wood products company has signed a deal with Pratt & Whitney Power Systems, which will deliver a biomass heat recovery power plant, comprising two Turboden 65 HRS Organic Rankine Cycle (ORC) turbogenerators, to West Fraser’s Chetwynd Forest Industries plant. The timber company has a 20-year electricity purchase agreement to sell 180 GWh/year of wood biomass, from two sites, to utility company BC Hydro.
Turboden is a company of Pratt & Whitney, a subsidiary of United Technologies Corp.
The Chetwynd plant produces 280 MMfbm of lumber products annually, and the ORC units will use thermal oil from a new biomass system installed to burn the plant’s residual hog fuel. About 50% to 60% of biomass fuel for the ORC units will come from local sawmill operations, and the timber company will buy the rest in the form of logging residues.
The two Turboden systems will be delivered to West Fraser by the end of 2013, with installation and commissioning expected in 2014. Commercial operation is planned by the second quarter of 2014.B.C. biomass plant, BC Hydro, biomass heat recovery power plant, British Columbia biomass plant, Chetwynd Forest Industries, logging residues, Organic Rankine Cycle, Pratt & Whitney Power Systems, sawmill residues, Turboden, United Technologies Corp., West Fraser Timber Company
