What LOS Gruppen does

LOS Gruppen AS is a privately held Norwegian industrial holding company founded in 1983 and headquartered in Rubbestadneset, Bømlo (Norway), operating 14 wholly-owned and majority-owned subsidiaries across 13 locations. The group delivered 838 MNOK in revenue with 449 employees, organized around five service areas: low-voltage and high-voltage electrical installation, ship service and maritime conversion, machining and metalworking, and solar/heat/charging solutions. Its customer base spans Norwegian government, municipalities, healthcare and education infrastructure (Statsbygg, Bergen Kommune, Helse Bergen, Vestland Fylkeskommune, UiB), power utilities and grid operators (Hafslund Nett, Statkraft, Lyse Elnett, Skagerak Nett), maritime and port operators (NORLED, Bergen Havn, Ålesund Havn, Kristiansund Havn), and emerging data center clients (Kryptovault).

The group's core technology assets are two patented innovations: RockRoller, a proprietary method for routing power cables through bedrock boreholes (3–4 km capability, used in projects such as a 145 kV cable at Leikanger Power Station), and Zinus, a patented autonomous dry-connection shore power system rated for up to 50,000 connections and 7.5 MW charging in Arctic conditions. LOS Power holds in-house 170 kV cable certification from four global manufacturers (LS, Pfisterer, Brugg, NKT, TE), eliminating reliance on third-party specialists for critical high-voltage work. The group is ISO 9001, ISO 14001, and ISO 45001 certified (DNV and Kiwa) and complies with the Norwegian Transparency Act, with these certifications acting as procurement prerequisites for public sector framework contracts.

Revenue is generated primarily through project-based professional services and hardware sales under multi-year framework agreements (rammeavtaler) and competitive tenders with public and private clients. Pricing is quote-based and not publicly disclosed. The go-to-market combines enterprise field sales led by senior leadership for large public and utility accounts with regional subsidiary offices serving mid-market and residential customers (heat pumps, residential electrical, EV charging). Recent strategic activity includes the merger of LOS Cable Solutions and LOS Power Services, the integration of FLM Elektro, Northern Norway expansion, and the Zinus partnership with NORLED covering 7 ferry routes, indicating active consolidation and geographic expansion within Norway's green-transition infrastructure market.
