Background

The 160 MW subcritical coal plant began operating in 1984.[2]

In 2015, the plant was converted to burn both coal and wood pellets.[3]

In December 2021, the Finnish capital announced that its energy company Helen was ready to shut down its plant ahead of schedule. More specifically, it would phase out coal more than 5 years earlier than initially planned, with the plant’s doors officially closing on April 1, 2024.[4][5]

In February 2023, the planned retirement was delayed by one year. Salmisaaari B would be decommissioned in April 2025.[6]

On April 1, 2025, the 177 MW unit was retired at Salmisaari power station.[7]
