TENSIO TS AS

Overview

Tensio TS AS operates as a regional grid company with 18 active concession cases focused almost exclusively on transmission infrastructure — transformer stations, high-voltage cables, and power line upgrades across central Norway. The company's portfolio reflects a systematic effort to reinforce and expand the 66–145 kV grid to meet growing industrial and consumer demand, including a dedicated 132 kV line to serve the Holla smelter and a new submarine cable connection to the islands of Frøya and Hitra. With no Statnett queue presence, Tensio's role is squarely on the distribution and regional transmission side rather than generation.

Active Regions

Strategic Focus

Tensio TS AS is a regional transmission system operator focused on reinforcing and expanding the high-voltage grid across Trøndelag to meet rising industrial and consumption demand. Key themes include voltage upgrades (66 kV to 132/145 kV), new transformer stations in urban and coastal areas, island grid reinforcement (Frøya, Hitra), and dedicated capacity lines for heavy industry such as the Holla smelter. The company is not active in generation or the Statnett queue, confirming its pure infrastructure operator role.

Recent Activity

August 2026 saw meaningful progress on two significant grid projects: the 132 kV Orkdal–Gjølme line entered public hearing (Høring) on 12 August, and the 132 kV Aura–Driva modification at Nisja advanced to formal application (Søknad) stage on the same date — indicating active regulatory processing of major transmission investments.
