What Tensio does
Tensio AS is a privately held Norwegian electricity distribution system operator (nettselskap) that operates and maintains the regional power grid across Trøndelag, serving approximately 280,000 customers and 500,000 residents through 29,000 km of lines and cables, 100 transformer stations, and 13,000 network stations. The company delivered 9.9 TWh of electricity in 2025 with 99.90% uptime and completed 87,069 maintenance operations despite three major extreme weather events. Its core technology stack includes 132 kV high-voltage transmission lines, drone-based line inspections (via Airpelago), LiDAR/helicopter-driven vegetation management, and integrations with national infrastructure systems (Elhub, Elsmart, Geomatikk).
Tensio generates revenue primarily through regulated network tariffs (nettleie) set by the Norwegian Energy Regulatory Authority, supplemented by one-time connection fees, grid-relocation charges, and emerging energy-coordination advisory services. It serves four customer segments: residential households (primary), electrical installers and contractors (via a professional partner portal and Elsmart), large commercial and industrial customers requiring >1 MW connections (data centers, hydrogen, aquaculture), and municipalities engaged in energy planning. The group operates through Tensio AS (parent, headquartered in Stjørdal) and two wholly-owned operating subsidiaries—Tensio TS AS (South Trøndelag, Trondheim) and Tensio TN AS (North Trøndelag, Steinkjer)—with 537 employees distributed across 20 regional locations. Ownership is split between NTE (40%), TrønderEnergi (40%), and KLP (20%), with Audhild Kvam as CEO and Jan Arve Haugan as Board Chair. Strategic positioning centers on the Norwegian energy transition: Tensio participates in the Enova-funded Euroflex flexibility-market consortium (2024–2026) and pilots a regional energy coordinator function with peer DSOs Elvia and Lnett.

Revenue model
- Network tariffs (nettleie): Charges for electricity transmission through the power grid. Customers pay for the cost of building, operating, monitoring, and maintaining the power network. Tariffs are regulated by national authorities and vary by customer type (apartment, single-family home) and region (North Trøndelag vs South Trøndelag). From January 2026, annual network tariff for apartment customers in North Trøndelag: 7,860 kr (down from 9,471 kr in 2025); for single-family homes in North Trøndelag: 15,108 kr (down from 18,276 kr in 2025).
- Connection fees and facility contributions: Charges for new connections to the power grid and contributions for grid reinforcement when existing capacity is insufficient. Customers must pay all or part of the connection costs based on their location and capacity requirements.
- Service charges for grid relocation: Fees charged when customers request relocation of grid infrastructure (poles, cables, transformer stations) due to construction projects or other needs. Based on actual costs with maximum 15% adjustment from estimated amounts.
- Energy coordination services: Regional energy coordination pilot project with Elvia and Lnett (2024-2026), funded partly by Enova. Provides guidance to municipalities and businesses on energy system utilization and limitations.
