Substations

We provide Finland’s best substation services from design to commissioning. Our expertise covers the entire substation lifecycle, from preliminary design to the latest modernisations. We ensure that substations meet all technical requirements and are of the highest quality. We have extensive experience and strong know-how in demanding 400 kV high-voltage substation projects.

With our unique substation expertise, we bring our customers’ visions to life every day.
We design, build, maintain and modernise substations for distribution and transmission networks, as well as those connected to wind farms, solar power plants, data centres and Battery Energy Storage Systems (BESS).

Our team has broad expertise in all voltage levels commonly used in Finland, covering the design, construction and maintenance of substations. Our services include all aspects of substation design. We design and build all substations on a turnkey basis – safely, efficiently and in full compliance with all standards.

We always provide a low-emission material option and help our customers reduce their carbon footprint, for example, by using low-emission insulating gas solutions or recycled steel.
