Project fact file

By the end of the 4th quarter 2021, the installation of 72 Nordex N149/5.x MW turbines – with a hub height of 105 metres and a rotor diameter of 149 metres – should be completed. These employ the very latest wind turbine technology and provide renewable energy with no CO2 emissions and the least possible impact on the surrounding natural environment.

Øyfjellet Wind Park will annually produce around 1,200 GWh, or 1.2 TWh. This is enough energy for 36% of Alcoa’s annual electricity needs, or for 75,000 households, around 162,000 people. This corresponds to 67% of all those who live in Nordland.

Aluminium producer Alcoa, which is Mosjøen’s cornerstone industry, has purchased all power production from the wind park for the next 15 years. This guarantees opportunities for growth and contributes to safeguarding 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. The roads, turbines and buildings to be constructed are estimated to cover 2-3% of the licenced area. Concentration of the turbines means excellent utilisation of the area, and adjustments and improvements have continuously been made in line with feedback from the local community.


Construction begins

Construction of internal roads, crane pads and turbine foundations.

Construction of transmission line

Construction of 132 kV transmission line between the wind park and Marka substation.

Construction of switchgear

Construction of 132 kV switchgear for connecting the wind park to Marka substation.

Objection review from NVE

NVE decides not to recognise the received objections to the ETC plan for the Øyfjellet wind power installation. NVE states that the assessments conducted have been carried out in compliance with the relevant regulations and the established assessment programme. The case has been submitted to the Ministry of Petroleum and Energy for the final decision.


Detailed plans approved

The detailed plans for realising the wind park – the environment, transport and construction (ETC) plans – are submitted. The plans are designed to ensure the least invasive development possible. Øyfjellet is taken out of the planning area after local consultation. The plans are approved by NVE in December 2019.

Main contractor

Veidekke is selected as the main contractor, alongside a number of local businesses as sub-contractors.

Road construction begins

Construction of the access road and improvements to Tveråveien begin.

Supplier of transmission line

Linka, from the Municipality of Inderøy, is selected to supply the 132 kV transmission line between the wind park and Marka substation.

Supplier of the interface between transmission line and substation

Helgeland Kraft, with headquarters in Mosjøen, is selected to supply the interface between the transmission line and Marka substation. This involves the delivery of 132kV main breaker to Marka substation.

Supplier of operations and maintenance of turbines

Nordex is selected as supplier of operations and maintenance of turbines, and is set to become a long-term member of the local business community.


Long-term power purchasing agreement

In order to secure access to local power, a long-term power purchasing agreement is agreed to the effect that all wind power produced for the next 15 years will go to the Alcoa aluminium works in Mosjøen.


NVE grants permission for 400 megawatt capacity.


Final authorization

The Ministry of Petroleum and Energy grants final authorization for the project.


Application submitted

Licence application submitted.

Support from the Municipal Council

Vefsn Municipal Council supports the application. Following dialogue with the local community, it is decided that the Øyfjellet area around Stortuva should not be developed.

License for construction given

The license for the construction of the wind park is given by NVE.


Project agreement

Local landowners and industry agree to the project to provide more green energy to industry.
