Biopower

Electricity produced from biomass is called biopower. Biopower is today, after nuclear- and hydropower, the third largest source of electricity in Sweden. Compared to wind power bio-power is a three times as large source of electricity!
Biopower is produced by biomass, usually wood fuels, burning in a furnace connected to a boiler. This occurs in a CHP-plant. The heat generated is used to heat the water vapor which in turn makes the turbine rotate, and electricity can be generated. The excess heat is distributed through a district heating network to homes and industrial users. It is as easy as it sounds - Bioenergy delivers electricity and heat!
Simultaneous production of electricity and heat is called cogeneration. A CHP-plant is different from a heating plant by both electricity and heat produced. In Sweden there are about 160 co-generation facilities.
