Gresslifoss power plant

The power plant uses water from the Nea watercourse, and has a short headrace tunnel and a long tailrace tunnel.

The power plant's intake reservoir is Lake Gresslidammen; the dam construction itself is a gravity dam.

The gross height of fall is 34 metres.

The power plant was upgraded in 2002. The power plant is equipped with a vertical Kaplan turbine that can take in 80 cubic metres of water per second.

In 1878 one of Norway's largest coin discoveries was made in the area where the power plant is built. During potato harvesting a treasure was uncovered that included 2253 coins, various silver currencies and a gold-plated silver bird broach. The Gressli Bird is an elegant piece of handiwork. The coins originated from around the year 1090. One theory is that the treasure is connected to one of the most important pilgrim routes from medieval times which passes close by where the treasure was found. Pilgrims from the east and west took this route onwards to Nidaros Cathedral.
