Heat and power – combined strength
CHP production with an energy-efficiency of 85% reduces emissions, as well as the demand for electricity from the grid. For instance, CHP accounts for 73% of the energy consumed at Norrsundet Pulp Mill, 63% at the integrated Veitsiluoto Mill, and 59% at Sachsen Mill, which produces newspaper. A modern non-integrated chemical pulp mill such as Enocell produces from its own fuels 53% more electricity than it uses in pulp production.
Several Stora Enso mills provide energy for local district heating schemes. The 25 000 residents of the town of Varkaus are kept warm throughout the year mainly thanks to secondary heat from Stora Enso's Varkaus Mill. The towns and villages of Heinola, Kotka, Nymölla and Skutskär are also heated through similar schemes.
