Myllykoski Heat and Power Plant – supplies Myllykoski Paper Mill with electricity and heat

Myllykoski Paper’s history goes back more than 100 years. Nowadays Myllykoski Paper is owned by the Myllykoski Corporation and M-Real. With 500 employees, the paper mill produces 500,000 tonnes of paper annually. Myllykoski Heat and Power Plant, owned by Vattenfall, is connected to the mill.

Vattenfall Oy took over ownership of Myllykoski Heat and Power Plant in February 2001. The partnership agreement stipulates that Vattenfall will supply electricity and heat to the mill for 17 years. Following the acquisition, Vattenfall began by modernising the heat and power plant. 

Modernisations – investing in efficiency

After taking over the heat and power plant, Vattenfall invested in a new solid-fuel boiler that burns bark, waste sludge, purchased biomass and peat, and in two gas-fired boilers between 2000 and 2001. In 2009 Vattenfall invested in a new back-pressure turbine. 

As well as providing power and heat to the mill, the plant produces heating for the village of Myllykoski in Kouvola. The power plant also supplies the nearby pigment factory with flue gas. 

Protecting the environment

Since acquiring the plant, Vattenfall has reduced several of the plant’s various emissions to the air. The airborne emissions have decreased due to the introduction of cleaner fuels (coal has been replaced with biomass fuels and natural gas), power plant investments and improved gas cleaning techniques. Flue gases are now cleaned using a fabric filter and gas scrubber system. Some examples of emission reductions since the year 2000 are:

• sulphur dioxide and particle emissions cut by 90% 

• carbon dioxide cut by 40–60%

• nitrogen oxides cut by 25%.

• CO2 emissions cut by 50%
