Norhard AS, established in 2007, is a full-service provider for full profile directional drilling and lining of penstocks for hydropower plants. It enables environmentally friendly solutions through game changing drilling technology based on in-house development and production. Many hydropower plants with pressure shafts from Norhard and with a total production capacity of about 250 GWh of clean renewable energy are now in operation all over Norway.
Norhard`s office and workshop are located in the small village Tonstad about 110 km south west of Stavanger.
