Number of windmills: approx. 50
Output: 300 MW
Production: 990 GWh
Equivalent to the consumption of: approx. 60,000 households
Project status: Report sent to NVE
The project is located in the mountain area south west of Tonstad, west of Lake Sirdal in the municipality of Sirdal in Vest-Agder and the municipality of Lund in Rogaland. The area has very good conditions for the development of wind power, with an average median wind of approximately 8-8.5 m/s at a height of 120 m above ground.
It may be relatively easily to connect the project to the existing power grid in the area, which is located in the vicinity of the Tonstad power plant, Norway's biggest hydro power plant with a reservoir. Technically speaking, wind and hydro power is a favorable combination due to production patterns and, with connection into the Ertsmyra key power node, the power from the Bergeheia wind farm will be distributed to other parts of Southern Norway, which is a region where demand for power will increase.
The main access will be from the municipality of Lund and county road 3/985. An overall assessment shows that it should be possible to bring in the necessary equipment without making improvements that are too extensive to the public road network.
The connection to Ertsmyra is also favourable in view of the proximity to foreign connections. This proximity enables export to, inter alia, Germany, where power from Norway can replace coal, gas and nuclear power.
Norsk Vind has entered into agreements with all landowners that will be directly affected by the project. A landowner group has also been established with a committee that will work with us to safeguard the interests of the landowners through the planning and eventual construction of the project.
Publicly available information and existing databases of important types of nature and endangered species indicate that the wind power plant may be realised without major conflicts with respect to biodiversity. The delimitation of the project is based on objectives for sufficient distance to existing buildings to make the visual impact of the project acceptable and to enable fulfilment of the guidelines for noise and shadow casting.
In addition to the initial mapping of the biodiversity already carried out, an extensive impact study will be conducted to significantly increase the knowledge base of biodiversity in the area. This will be an important factor when considering whether a permit for wind power in this area should be granted or not.
31. January 2020:
The turbine installation works are slowly but steadingly progressing and the half-way mark (35 installed turbines) was passed in the middle of January. 20 turbines at Eikeland-Steinsland are now completly installed, i.e. in total 38 completed turbines including Skinansfjellet wind farm.
The main cranes are expected to start installation at Gravdal wind farm in March and hopefully complete the last turbine in May.
