Finland’s Fortum has won a contract to install what it says is the Nordic countries’ largest rooftop solar system.  

The system is planned for installation on around 40 commercial buildings belonging to Finnish retail giant S Group and will have a total capacity of 10 MW.

Fortum said it will handle the planning, management and equipment procurement for the project. Installation is scheduled to begin this spring at sites across Finland and to finish in the autumn, with the exception of a few new sites.

The installations will boost Finland’s solar PV output by around 30 per cent from its current total installed capacity of close to 35 MW (data from the end of 2017).

Mikko Halonen, managing director of utility S-Voima, said the overall S Group, which operates around 1600 facilities cross Finland, “has a shared goal to use our own renewable energy to produce 80 per cent of the electricity we consume in 2025.

“Our sites’ electricity consumption peaks during summer, right when the sunlight lasts longer and is more intense. In the best cases, during summer we can produce enough solar energy to satisfy 100 per cent of the electricity needs of one building.”

And Tatu Kulla, Fortum’s head of business development, said: “Realizing our vision – for a cleaner world – isn’t easy nor can it be accomplished overnight. Fortunately, it is a goal that is also shared by many other companies and communities, and this S Group project to utilize solar energy in their commercial buildings is a prime example of that.”
