WORLDKINGS - Worldkings News - Europe Records Institute (EURI) Alholmens Kraft: Largest biomass cogeneration power station in the world

31-05-2022

(WorldKings.org) The power station has an installed capacity of 265 MW of electrical power. In addition, it provides 60 MW district heating for the city of Jakobstad and 100 MW process steam and heat for the UPM-Kymmene paper mill.

The Alholmens Kraft Power Station (also known as Jakobstad Power Station or Pietarsaari Power Station) is a biomass power station in Alholmen, Jakobstad in Ostrobothnia region, Finland. It is the largest biomass cogeneration power station in the world.

Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat because otherwise-wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover otherwise wasted thermal energy for heating.

The power station was commissioned in 2001. It was built next to the existing, now decommissioned power station. The power station is located slightly north of UPM-Kymmene Wisaforest pulp and paper mill in Alholmen. The decommissioned power station had two black liquor recovery boilers, one oil-fired package boiler, one bark boiler as well as several steam turbines with an electrical output of 75 MW.

The new power station was designed by Metso and its boiler was manufactured by Kværner. It employs 400 people. The power station has an installed capacity of 265 MW of electrical power. In addition, it provides 60 MW of district heating for the city of Jakobstad and 100 MW of process steam and heat for the UPM-Kymmene paper mill.

The new power station uses wood-based biofuels (forest residues) as the main fuel. Peat is also used while coal is a reserve fuel. It burns about 300,000 bales of forest residues per year. The power station is equipped with a circulating fluidized bed boiler with a capacity of 500 MWth, which is the largest biomass-fired CFB boiler in the world. The operating temperature of the boiler is 545 °C and the operating pressure is 165 bars (16,500 kPa).
