With a 192-megawatt capacity, Finland’s biggest hydropower plant is now producing carbon dioxide-free energy for electricity users.
Refurbishment of the number four unit started at the beginning of March and was completed on schedule. The project modernised the unit’s turbine, generator, and electrical and automation systems. At the same time, other auxiliary systems were also upgraded and repairs were made to the unit’s water channels. The power plant’s number three unit had previously underwent similar refurbishment.
“The power plant’s number three and number four units have been in use for 85 years; their modernisation was successful and carried out according to the planned schedule. A refurbishment project of the magnitude of the one now completed has never before been done at a Fortum hydropower plant in Finland,” says Project Manager Juha Tella from Fortum.
