Energy

A sulphate pulp mill produces energy - heat and electricity - from the wood raw material surplus of the bark and wood dissolved in the cooking solution. The amount of energy the Botnia mills produce exceeds their own consumption considerably. The surplus electricity is sold to the electricity grid, and the heat can be utilised by other converting industry mills as process heat or, alternately, the heat can be sold as district heat.

Energy sources for electricity in 2008

In 2008, Botnia generated a total of  2,147,385 MWh.  In addition, it procured 209,750 MWh of electricity through its shareholding in Pohjolan Voima Oy.

The total of 2,357,135 MWh of electricity was generated as follows:

• 92.0% from renewable energy sources
• 5.9% from nuclear power
• 2.2% from fossil energy sources and peat

 

Specific carbon dioxide emissions from the use of fossil fuels to generate electricity procured by Botnia in 2008 were 3,3 g/kWh. The amount of spent nuclear fuel resulting from the electricity procured by Botnia was 0.16 mg/kWh.

This amount of spent nuclear fuel has been calculated using the coefficient 2.7 mg/kWh. More information on the recycling of fuel from nuclear power generation can be obtained from Radiation and Nuclear Safety Authority Finland, address www.stuk.fi/english/
