Background
The Naantali CHP power station was originally a three-unit, 375 MWt combined heating and power station built between 1960 and 1972. It included one 116 MW unit and two 125 MW units. The plant was fueled with bituminous coal, oil, refinery off-gas, biomass, and oil. Coal was imported via the attached coal port. In addition to electricity, the plant produced district heat for the Turku regional district heating network and steam for nearby industrial facilities. Aggregate electrical output was 145 MW.[8][9]
In July 2020, the coal-fired Unit 1 and Unit 2 were decommissioned.[10] As of November 2022, Unit 3 was only operating for part of the year.[11] Unit 3 was expected to be fully decommissioned by 2027.[12]
In June 2024, Unit 3 was mothballed. The unit was expected to be fully decommissioned in December 2024.[13]
Retrofit and conversion to biomass
In April 2014 it was reported that TSME planned to entirely replace the existing plant with a biomass and waste plant. The new CHP plant was to have an installed capacity of 244MW of heat, 145MW of electricity and 50MW of steam. Construction was to begin in 2015, with the new unit coming online in 2017. Although original plans were for the plant to be co-fired by coal, TSME later said it planned for the unit to be fueled 100% by biomass and waste.[14][15]
The new unit (Unit 4) was commissioned in December 2017[16], fueled by a mix of "biomass from forests, thinning logs, chipped poles, stumps, and industrial by-products such as bark and sawdust, straw and coal."[17] Unit 4 has a generating capacity of 253 MW.[18]
