Helen has a long track record of developing efficient energy platforms. Helen has created pioneering solutions for producing, storing and optimising energy in demanding urban environments. Helen’s energy production has been awarded as the most efficient in the world, and our current target is 100% carbon neutrality by 2030.

Helen is a forerunner in new energy solutions. The first two-way V2G charging point for electric vehicles in Finland was installed by Helen. It is also the first company in Finland to offer solar panels and energy storage for consumers.
