Rauma Harbour 400 kV Transmission Link for E-Fuels Facility

Leverer 500 MW strømtilkobling

Omexom in Finland is leading the design of a complex 400 kV transmission link to supply approximately 500 MW of power to Norsk e-fuel’s new e-fuels production facility at Rauma Harbour. This facility is planned to produce around 80,000 tonnes of e-fuels annually, with about 80% designated as sustainable aviation fuel (SAF), making it Finland's most significant industrial energy project to date. The project involves creating a reliable high-capacity connection between the harbour and Fingrid’s Rauma substation to meet the facility’s considerable electricity demand.

11,5 km krevende nettrute

The transmission link spans approximately 11.5 kilometers and consists of three distinct segments: 1.5 km of overhead lines, 7.5 km of underground cables, and 2.5 km of subsea cables leading into the harbour. The design process required navigating challenging land use constraints, environmental considerations, and technically demanding terrain. Early planning established route options and technical solutions to ensure a technically sound and economically viable design within these limitations. Fortum, supporting the grid connection planning and implementation, has appointed Omexom following its earlier involvement in the preliminary planning phase.

Ferdigstilling og betydning 2027-31

Scheduled to complete the general design by 2027, the project supports the e-fuels facility's expected operational start in 2031. This transmission connection forms the energy backbone enabling large-scale electrification at Rauma Harbour and underpins Norsk e-fuel’s project through its development, construction, and operational phases. The project exemplifies how complex, multi-segment transmission infrastructure can facilitate the energy transition in industrial settings and sets a precedent for similar electrification efforts in ports and industrial zones across Europe.
