Boiler plant delivered by MW Power inaugurated in Gällivare, Sweden
A new biomass and peat fired power plant was inaugurated on 16 March 2011 in Gällivare, Sweden. The steam boiler with related technology and steel structures was delivered by the Metso-Wärtsilä joint venture MW Power.
When approaching Gällivare, a municipality with around 18,000 inhabitants situated in Swedish Lapland, you can’t miss the new power plant. Rising 30 meters into the sky, the blue-gray landmark represents a major investment for the municipality. With a total investment cost of around EUR 50 million, the plant produces 21 MW of district heat to local residents and 9 MW of electricity to the national grid. With the new plant, Gällivare Energi AB is contributing to both national and international environmental and renewable energy targets.
“Through this investment, we have secured the production of district heat at a reasonable price for local residents and businesses while taking a significant step towards energy production based on renewable fuels,” says Mats Eriksson, whose 30-year-long career as Managing Director of Gällivare Energi AB ended at the inauguration.
“We are very proud of and pleased with our new plant – it secures the energy supply of our municipality for at least 30 years into the future. Among other advantages, the new plant enables operation all year round. In the past, we could only operate the plant from September to June and then we had to shut it down. Now our energy production capacity has doubled. Naturally, we will also need a lot more fuel than before, which is why we will increase the proportion of wood-based biofuels in particular, such as wood chips.”
Founded in 1978, Gällivare Värmeverk AB is fully owned by the municipality. At the inauguration, its name was changed to Gällivare Energi AB. The old plant, constructed 25 years ago, will remain in operation and use peat as its primary fuel, as does the new plant. It was Sweden’s policy in the late 1970s to construct peat-fired power plants in the northern parts of the country. The peat used by the Gällivare plant is still procured from within municipal boundaries. In 2007, however, Gällivare Värmeverk set its sights on the future, and above all on renewable fuels, when it made the decision to invest in a new modern power plant capable of using wood-based biofuels as well. At that time, Metso company, MW Power was selected as the boiler supplier. “The steam boiler of the new plant is based on the same Bubbling Fluidized Bed technology (BFB) as the old one, but of course it is more modern and now enables large production of electricity. Thanks to the new technology, the energy in fuel can be utilized to almost hundred percent,” says Eriksson.
The plant was inaugurated by Sweden’s former Minister of Environment and Energy Olof Johansson. Metso and MW Power were represented at the event by Matti Lönnroth, Project Manager, MW Power Oy and Jarmo Almenoksa, Project Delivery Manager, MW Power Oy. The inauguration ended with a tour of the new plant. An Open House event will be organized in May at the plant for all local residents.
