What Oneco does
OneCo is a privately held Norwegian industrial group (konsern) headquartered in Kristiansand, operating across telecom, electrical power, transport infrastructure, building and industrial automation, and welfare technology. The company delivers complete electrotechnical systems — from design through installation to ongoing operations and maintenance — for critical infrastructure including power grids, tunnels, railways, mobile networks, and public buildings. Its portfolio spans active DAS indoor mobile coverage, high-voltage work up to 420 kV, power-line construction and maintenance, building automation (SD-anlegg, EOS energy monitoring), and an ISO 27001-certified, medical-device-approved AI fall-detection product (OneCo MultiSensor) priced at 5,000 NOK/month for three sensors.
The business model is primarily project-based enterprise contracting combined with recurring frame-agreement maintenance. OneCo acts as main contractor or subcontractor to a concentrated set of large Norwegian counterparties including Telenor, Bane NOR, Statens vegvesen, Glitre Nett, Norgesnett, Elvia, Equinor, and Oslo Airport Gardermoen, with notable contract values such as approximately 72 million NOK for the Drammen Station electrotechnical installation. Distribution is direct enterprise sales supported by five regional offices across Norway and a Sweden operation. The company has wholly owned subsidiaries OneCo Networks (telecom) and OneCo Infra (road and rail).
Ownership rests with Norwegian holding company Aars, and the company has undergone multiple restructurings of its telecom subsidiary (January 2024 and April 2026) due to a declining telecom market. In May 2026 Kristin Folge was appointed CEO, succeeding Tore Sjursen who continues as board chairman; this leadership change signals a strategic emphasis on construction and property verticals. OneCo is also one of Norway's largest apprenticeship companies, training skilled workers across electrical, automation, and telecom trades, and has accumulated more than 100 completed tunnel projects and collaborations with over 40 grid companies.
