Fingrid to refurbish one of Finland’s most important substations in Rauma

Fingrid, the Finnish transmission system operator, has decided to overhaul the Rauma substation, which is one of the most important substations in the power system of Finland. Work will begin at the station in 2022. The refurbishment will be completed in 2024 or 2025.

The Rauma substation is one of the most important substations in the power system of Finland in terms of system security. In addition, the substation ensures the security of supply of electricity to the Rauma and Satakunta region.  

The cross-border connections from the Rauma substation (FennoSkan 1 and FennoSkan 2) enable a total of 1,200 MW of electricity to be transferred between Sweden and Finland. The Rauma substation is also important for the functioning of the Olkiluoto nuclear power plant.   

The Rauma substation contains a large amount of ageing equipment and requires modernisation and refurbishment. This will ensure the system security of the main grid in the region in the future. The substation refurbishment will cost a total of EUR 24 million.  

“The substation overhaul project is a large and demanding project that requires good planning. Detailed outage plans must be prepared for the duration of construction and repair works at the substation to ensure that the refurbishment does not disrupt the normal operation of the power system,” says Jarmo Henttinen, Project Manager at Fingrid.   

A reliable main grid is the backbone of Finland and the prerequisite for a functioning society. The project will enable Fingrid to transmit electricity reliably and maintain the balance between electricity consumption and generation.
