North American wood companies have the world largest ORC-based biomass power plants

New power systems have a total power capacity of 13 MW at each site to supply electricity to BC Hydro.

Turboden, a group company of Mitsubishi Heavy Industries (MHI), leader in Organic Rankine Cycle (ORC) power systems for distributed generation from renewable sources and waste heat is commercial operating two biomass-fed ORC units supplied to West Fraser, a leading integrated wood products company based in the Canadian province of British Columbia.

A successful proponent under BC Hydro’s Phase 2 Bioenergy call, West Fraser’s four 6.5 MW ORC turbogenerators are installed at Fraser Lake and Chetwynd sawmills. The power systems have a total power capacity of 13 MW at each site to supply electricity to BC Hydro.

In the West Fraser projects, the heat of flue gas from biomass combustion is conveyed in a closed-loop system to the ORC unit which converts thermal energy into electricity. The lower temperature waste heat is released to the environment by means of evaporative cooling towers.

In addition to West Fraser’s plants, Turboden is starting up the world largest biomass-fed ORC power unit, supplied to Maine Woods Pellet Company for its pellet production facility in Athens, Maine. The ORC system will produce 8 MW by converting the heat of thermal oil generated by wood residues from debarking and chipping operations. The start-up of the plant is scheduled for March 2016. Maine Woods Pellet is the second project in the United States for Turboden, after the 1 MW ORC unit installed at Albany County Sewer District in Menands, New York.

West Fraser and Maine Wood Pellet plants are important milestones for Turboden’s advancement in the North American market. Currently, the company is present with 6 references in Canada and 2 in the United States.

The growth path in North America - with a series of projects where Turboden ORCs were selected thanks to a track record of efficiency, reliability, ease of operation and low maintenance costs - was marked by the first unit installed and operating in Rosetown, Saskatchewan, in Canada, in November 2011. Peak performance of the West Fraser ORC systems has exceeded the design.

Along this path, Turboden received orders from several power systems in North America with an overall capacity to date of about 45 MW. Furthermore, important power systems equipped with a Turboden ORC are installed in other prestigious wood product companies in Canada. A 2.2 MW ORC unit is operating in Vanderhoof, British Columbia at Nechako Lumber (Sinclar Group) since February 2013, a 3 MW ORC converts heat to power at Manning Diversified Forest Product (MDFP) wood residue biomass plant in Northern Alberta since the beginning of 2015, another 3 MW ORC module is under construction for Canfor Corporation in Chetwynd, British Columbia. This is a pellet plant that will be operated in partnership with Pacific Bioenergy Corporation.
