Looking to the future

Our history dates back to the establishment of energy-intensive industry and energy production in Norway at the end of the 19th century. Today, we are a fast-moving technology company that, on the back of our experience and our established position, is creating new opportunities in renewable energy production for small and medium-sized power plants in Norway, Indonesia, and the Balkans.

Every day, we work to help our customers secure a sustainable small power plant that is financially profitable, and that safeguards values that are important for people, communities, nature and the environment.


Tinfos and World Heritage

Our power plants in Notodden and our head office are centrally located by the Tinnelva river in Notodden, in Tinfo’s cultural environment.

This is a protected area with three generations of hydropower plants that offers a cultural-historical perspective on industrial beginnings that were based on hydropower, and a perspective on social development in Norway, in the late 1800s and early 1900s.

Ever since Tinfos was established in 1894, we have stayed in the area – and left our mark on it. Now, modern business and lifestyle are combined with culture and tradition. The area is an important part of UNESCO’s Rjukan – Notodden World Heritage Site.
