Storåselva - Norway

In December 2015, Nord-Trøndelag Elektrisitetsverk AS (NTE) awarded a contract to ANDRITZ HYDRO for the supply of electro-mechanical equipment for the Storåselva hydropower plant in central Norway.

Owned by North Trøndelag County Council, NTE is a utility focusing on production and distribution of electrical energy. In total the company operates 29 hydropower plants and two wind parks.

The new Storåselva underground power station will be built inside the Skro­moen Mountain, with an intake about 1km west of Mollansetra, 16 km  from the city of Snåsa and near the  Blåfjella-Skækerfjella Nasjonalpark.

ANDRITZ HYDRO will supply three horizontal 8.85 MW Francis turbines, associated generators, automation system and electrical power systems, inlet pipes, and cooling systems. Engi­neering, procurement, and manufacturing of the core components were finished in late 2016. Assembly of the generator is now ongoing. The Fac­tory Acceptance Test is scheduled for January 2017.

After commissioning in 2018, HPP Storåselva will deliver about 75 GWh of electrical energy per year.
