Over the next two years, a large-scale cogeneration facility will be built on site at Thurso that will allow for much of the energy and steam used in the pulping process to be converted into energy and outsourced to the Quebec power grid.
Fortress Paper Ltd. – the owner of the Thurso mill says their large-scale cogeneration will export 18.8 megawatts (of a possible 25 megawatts) to the province of Quebec. Fortress currently has a 15-year contract with the province for this energy.
There can be several types of cogeneration, but the most common is called Combined Heat and Power (CHP) cogeneration which takes the by-product heat used in manufacturing and converts it to energy.
This helpful video details how this by-product heat gets converted into energy and electricity:
