Turbine manufacturer Doosan Škoda Power has delivered a 270MW steam turbine for the Metsä Group’s bioproduct mill in Kemi, Finland.
The Kemi bioproduct mill produces 1.5 million tonnes of softwood and hardwood pulp per year, as well as other bioproducts. The new mill will produce 2.0TWh of renewable electricity every year, equivalent to about 2.5% of Finland’s total electricity production.
The mill will have an electricity self-sufficiency rate of 250%, will operate without using any fossil fuels will supply surplus electricity to the national grid.
As part of the contract, Doosan Škoda Power will also deliver a generator, condenser, and rest of the accessories for the steam turbine.

The turbine itself has a tailor-made condensing turbine section solution and is equipped with two steam bleed connections of different pressure levels.
“The engineering, procurement and manufacturing phase of the project has been a challenge due to the COVID-19 restrictions, which caused significant delays together with increase in the raw material costs. Despite all these challenges and thanks to the extraordinary effort, our team managed to deliver in full as per the client requirements.
“Heavy lifts have currently been carried out on the construction site, mechanical assembly continues, and commissioning will follow. We are staying focused to keeping up the good work,“ said Jindřich Závodný, project manager at Doosan Škoda Power.
“We have set high material, energy and environmental targets for the Kemi bioproduct mill. Only the best available technology will be used. That is why we require that also our partners provide the technically most reliable solutions. Based on our experience, Doosan Skoda Power solutions fits into this category,” said Jari-Pekka Johansson, director of the bioproduct mill project at Metsä Fibre.
The new mill will replace the current Metsä Group pulp mill in Kemi and will be the largest wood processing plant in the northern hemisphere, according to the Group.
