Aurajoki Oy Joins Fingrid and Enersense in Low-Emission Steel Pilot Project
Enersense, a provider of zero-emission energy solutions, won a contract in Fingrid’s public bidding process at the beginning of the year for the construction of three new 110 kV substations in the Harjavalta area. As part of the project, Enersense’s delivery includes all steel structures to be built in the substation area, requiring a total of 76,000 kg of steel.
In the manufacturing of these steel structures, Enersense relies on domestic expertise, with Aurajoki handling the production and surface treatment of the structures. The structures consist of 110 kV transmission line portals to be built in the substation area, with delivery scheduled for the fall of 2025. There will be substation portals for connecting a total of fourteen transmission lines.
“The green transition and the use of low-emission materials related to it will become more common in the future, so it’s particularly exciting to be part of such a pilot project at this stage. Aurajoki’s commitment to carbon neutrality also strongly supports sustainable steel construction,” says Timo Tuominen, Director of Steel Structures of Aurajoki.
Through its partners, Enersense procures all the steel structures in question as low-emission steel. In this project, low-emission steel means that the structures to be delivered are made of recycled steel and their carbon dioxide emissions are, on average, approximately 40% lower compared to structures manufactured using iron ore-based production methods. The project is Fingrid’s first of this scale in Finland where all steel structures in the substation area will be delivered made of low-emission steel.
“We have invested heavily in sustainability and its continuous improvement in our operations. It’s fantastic to participate in such a pioneering project, which not only promotes sustainable development but also strengthens our role as a leader in sustainability within our industry,” Tuominen adds.
