Companies in Aarhus

Vestas began in 1898 as Vestjysk Staelteknik, a Danish metalworking shop that made agricultural equipment — and only entered wind power in 1979, when the oil crisis made Denmark look seriously at renewable energy. That late pivot turned out brilliantly: Vestas is now the world's largest wind turbine manufacturer, having installed more wind capacity than any company in history, with over 170 GW of turbines spinning across the globe. The company's turbines range from onshore models in the 2-6 MW class to offshore giants like the V236-15.0 MW — a machine with a rotor diameter of 236 meters, taller than the Eiffel Tower, capable of powering roughly 20,000 European households per turbine. Vestas also operates one of the wind industry's largest service fleets, maintaining turbines across 80+ countries, and its software platform monitors thousands of machines in real time. With about 30,000 employees and annual revenue near €15 billion, Vestas has survived the wind industry's boom-bust cycles by vertical integration — designing its own blades, towers, and control systems — and by treating service revenue as a core business, not an afterthought. For project developers, Vestas offers the industry's longest track record and the largest installed base.
