The installation of 72 Nordex N149/5.x MW turbines – with a hub height of 105 metres and a rotor diameter of 149 metres – uses the very latest wind turbine technology and provides renewable energy with no CO₂ emissions and the least possible impact on the surrounding natural environment.
Øyfjellet Wind Park will annually produce around 1.3 TWh. This is enough energy for 39% of Alcoa's annual electricity needs, or for 82,500 households, around 178,200 people – corresponding to 73% of everyone who lives in Nordland.
Annual expected production is based on many years of weather data collected from measurement masts placed in the area. For wind power, it is common practice to calculate P50, P75 and P90 figures. At ØWAS, the calculations are: P50 indicates 1.3 TWh, P70 indicates 1.2 TWh, P90 indicates 1.14 TWh.
Aluminium producer Alcoa, Mosjøen's cornerstone industry, has purchased all power produced by the wind park for 15 years. This guarantees opportunities for growth and helps safeguard hundreds of Norwegian jobs.
The Municipality of Vefsn covers an area of 1,849 km². The licenced area covers 40 km², around 2% of the municipality. Roads, turbines and buildings cover roughly 2–3% of the licenced area.
