What Hywer does

Hywer AS is a Norwegian total-solutions provider to the small and medium hydropower industry, operating as a wholly-owned subsidiary of Saint-Gobain since its 2020 spin-out from BD Vasskraft. The company delivers end-to-end project services — from concession planning and in-house engineering through construction and commissioning to ongoing operations and maintenance — for hydropower developers and large Norwegian utilities, with a disclosed reference base of 80+ completed small hydro plants and 600+ project deliveries.

Its core offerings span six integrated product lines: waterway components (gates, pipes, steel constructions, valves); turnkey construction and rehabilitation; in-house engineering; specialized drilling and pipe-lining using owned capital equipment (TBM 'Snøhvit', Herrenknecht HK250C directional drill, customized PPP380 pipe-pushing rig); operations and maintenance via the proprietary DK Kraft digital monitoring platform; and low/high-voltage electrical services through a dedicated Electro department established in 2025. Notable technical differentiators include TBM-based waterway tunneling — demonstrated on the 9.9 MW Mork kraftverk project where it replaced conventional driving with an estimated 700-tonne CO2-equivalent reduction — and proprietary intake/gate designs including the Fossekallen Coanda-effect system.

Hywer operates on a project-based, sales-led go-to-market serving both small hydropower developers and major energy companies (Statkraft, Hafslund E-co, Hydro Energi, Lyse Kraft, SFE, Eviny), with revenue mix spanning one-time component and project revenue plus recurring managed-services revenue from DK Kraft monitoring. Revenue is disclosed at approximately 650 million NOK (~USD 60M) against a workforce of 44-45 employees across headquarters in Dale i Sunnfjord and a regional office in Oslo. Customer concentration is moderate and split between large enterprise utilities and smaller independent developers, with no public listing, no disclosed funding rounds, and no AI/ML capabilities identified in the available evidence.
