A technical problem occurred in wind turbine number 18 at the beginning of June in 2023. Since then, the area around has been cordoned off, while technical personnel from the operator Nordex have assessed the damage and worked on repairs.

As part of the repair process, the gearbox has been removed from the wind turbine. This, along with other special circumstances surrounding the damage and repair work, has led to an unusual risk that the rotor falling could fall off the turbine. On January 27, the rotor became loose and fell off the turbine. Risk analyses had shown that this could happen, the area had been cordoned off and there was no danger to health or safety. This was an isolated incident and no other turbines are affected and will continue to operate normally.

Øyfjellet Wind will conduct a root cause analysis of both the damage in June and the rotor coming loose, in dialogue with the operator, Nordex.

Nordex gives furter details: "During a component exchange in June 2023 the works were postponed for safety reasons due to high wind. During this postponement the rotor moved out of position. Following an evaluation by Nordex Group experts it was decided that a special tool would need to be developed to bring the rotor back to position as this was the only feasible solution from a technical and safety perspective. The rotor unfortunately fell to the ground due to high wind before the special tooling could be installed. 

The turbine was installed in September 2022. The wind farm consists of 72 N149/5.X wind turbines totalling 400 megawatt (MW). 

As soon as the proper disposal of debris and operating materials has been completed, and a full survey of the remaining tower has been undertaken, a replacement rotor can be installed. 

This was an isolated incident and there is no risk to any other of the turbines on the Øyfjellet windfarm or in the wider fleet." 

We expect the tubine to be back in normal operation during the autumn of 2024.

Update 30 January 2024:

The wings are broken, and as soon as the weather permits it, we will cover the various components and start the clearance work.

During a standard gearbox exchange on turbine 18 a technical issue occurred with the rotor. The engineering and support team are currently working on a solution to repair the rotor. The work involves temporarily blocking the road to secure the area around the wind turbine. Øyfjellet Wind will return with more information when the road can be opened again.

Øyfjellet wind park was put into operation in September 2022. Øyfjellet Wind AS has now taken over the wind farm from the developer, Eolus Vind.

Øyfjellet Wind and Eolus Vind have agreed that final implementation, in line with the terms of the agreement for planning and construction of the wind farm (EPCM agreement), has been achieved. The parties also agree on the scope and responsibilities of each party with regard to the remaining works. Furthermore, the parties agree to terminate the agreement on technical and commercial operations. These services are transferred to Øyfjellet Wind AS.

Thus, Øyfjellet Wind AS takes over the wind farm. 

Øyfjellet wind park consists of 72 wind turbines with an installed capacity of 400 MW and an expected annual production of 1.3 TWh.  The wind farm has signed a 15-year power purchase agreement (PPA) with the Alcoa aluminium plant in Mosjøen. This means that the wind park contributes locally produced electricity to important industrial jobs

Turbine number 72 has now been put into operation. This means that all the turbines now have produced energy. - This is a very special milestone in the project, says the CEO of Øyfjellet wind park. 

-Recently, we have been working to put the remaining turbines into operation. Now we are finally at the finish line with this work, which is an important milestone on the way to completing the project. It will reduce emissions and contribute to more renewable energy locally, says Erik Mortensen, CEO of Øyfjellet Wind Park. 

Both the construction phase and the planning of the facility have been extensive. In total, over 100 agreements have been concluded with landowners, private individuals and companies to realize the facility, which will be a long-term contributor to jobs, growth and development in the entire region. 

- There are many people who have been involved in this project in various ways, and thus many who deserve a big thank you today. This applies in particular to the employees, who have worked hard to reach our goal with the commissioning of the facility. They have done a great job, says Mortensen. 

The fact that the wind farm is now operational means that there is no longer a need for NVE to consider an application for an extended deadline. 

Mortensen would like to thank partners and the municipality for their good cooperation and understanding that commissioning was delayed. The reason for the delay is the backlog after the pandemic and delayed deliveries as a result of the war in Ukraine. 

- We have had a good and close dialogue with affected parties during the project, and feel that we have been met with great understanding and goodwill from both partners, the Vefsn municipality and the residents. We are very grateful for that, concludes Mortensen, says Mortensen.
