The oldest systems on the site needed modernization to improve their reliability, capacity, and safety. To achieve this, the Finnish main grid operator, Fingrid Oyj, constructed a new building to house a 110 kV Gas-Insulated Switchgear (GIS) system, replacing an extensive, ageing air-insulated switchyard. The project also included the construction of new powerline structures, fences, a backup power generator, extensive landscaping, and fresh greenery. The construction process was carefully phased to minimize disruptions to ongoing substation and grid operations, and to ensure a smooth transition. The project also allows for future expansion of the substation's capacity, future-proofing it for the growing need for electricity.

The new heat pump building sits next to two dominating architectural landmarks: Vuosaari Power Plant A from 1987 and Vuosaari Power Plant B, built in 1998, both of which were designed by Virkkunen & Co Architects.

The project extends over two tributaries of the river Vuoksi and the culturally significant landscape of Imatrankoski rapids. The rapids were harnessed for power generation in the 1920s when the Imatra hydropower plant was constructed. This landmark industrial site was also the starting point of the first part of the Finnish main power grid. The historical significance of the area was why our client, the main grid operator Fingrid Oyj, pursued an exceptional substation facility.

It consists of two buildings housing transformers and a switchgear building, all in in-situ white concrete and clad over by an aluminum graffiti fence and an architectural steel mesh. The location is a central, urban site between the former Suvilahti power station that has been transformed into a cultural center and the still-functional Hanasaari power station. The site is located by one of the main traffic arteries leading to the city center.
