Quietly harnessing Sweden’s wind resource

The first two EWT wind turbines in Sweden were installed in the parish of Tarstad, just west of Svalov. They are owned by three local farmers; Christer Laurell and brothers Håkan and Thomas Palsson.

The wind turbine model is the EWT DirectWind54-900kW with a hub height of 75m and a tip height of 102m.

The turbine is a direct drive machine, which means that it operates without a gearbox. Due to having fewer moving parts than the conventional, gearbox-fitted model, the direct drive technology is widely acclaimed to be the quietest available. This proved a key feature in meeting strict planning regulations on noise, which the turbines achieved with a good margin. The project was tested thoroughly in the planning process, standing up to intense scrutiny time after time and proving robust without fail.

The EWT DirectWind54 direct drive turbine model provides higher efficiency, lower noise levels, less downtime and requires less maintenance than conventional gearbox technology.

Project partner Håkan Palsson said: “This turbine is the quietest and best on the market. With EWT, we have found a solution that gives us the best operational performance and is sympathetic to our neighbours at the same time.”
