The wind farm consists of twelve Vestas V136 Wind Turbine Generators (WTGs) with a capacity of 4.2 MW each. The turbines feature a tip height of 150 m, a rotor diameter of 136 m and a hub height of 82 m. The project also included a 5 km long access road, and internal roads 7.7 km in length, a new ro-ro quay on the sea shore, a substation with control room, and electricity infrastructure including ground cables, switchgears and a 55 MVA transformer. The regional utility, Sogn og Fordane Energi Nett, built a new overhead line to connect the site to the regional grid. The wind farm is expected to generate up to ~174 GWh of electricity yearly. That is enough clean, green energy to power between 8,700 and 10,900 homes (1).
(1) Based on an average consumption per household of 16,000-20,000 kWh/year (Norway Statistisk Sentralbyrå and Energy facts Norway).

Ice throw warning
Based on meteorological data the probability of ice throw at Hennøy windfarm is:
MEDIUM probability*
(updated on November 23, 2020)
* This information is provided to the best of our knowledge but please be aware that weather conditions can rapidly change.
Things to consider before entering the windfarm when there is ice throw risk:
- Avoid entering at all if the ice throw risk is stated as high and/or the road barrier is closed
- Assess weather conditions; is it low cloud cover, fog and temperature around 0 °C?
- Listen; the turbines will often make more noise when there is ice on the blades
- Watch out; if there has recently been icing conditions there may still be ice left, even though the weather has cleared
- Falling ice may drift with the wind
- If you are going near a wind turbine with ice on it, you should do so with the wind in your back
- The wind will most often come from the west during icy conditions

Important information to visitors
Please note:
There may be varying mobile coverage on the mountain
- Pay attention to traffic within the windfarm
- Please note that there are high voltage cables in the ground along the roads and in the air from the substation
- Keep your distance to ongoing works in and around turbines
- Please do not climb turbine stairs or other equipment
- Do not try to enter turbines, substation or control building. Observe rules and signs
- Keep away from wind turbines in bad weather, especially during thunderstorms
- Keep away from wind turbines in cold and wet weather as ice formation may occur on turbine blades. For more information, see "Ice throw warning" page
- Note that there are forestry and agricultural activities in the vicinity
- Respect the environment

Community
We involve local communities as soon as we start planning a new wind farm. We then consult with them at every stage of the development and operations. We set up construction liaison groups for each of our projects to make sure local people are fully involved while the wind farm is being built, so they can let us know about any issues regarding the community. This helps bonding with the local community and makes it possible to address any concerns at an early stage.
Meetings with the local community and local companies were held in August 2017. Local businesses were invited to present their products and services, and received information about the services that will be contracted during the construction phase.
Falck Renewables Vind AS will contribute yearly to a fund for the benefit of the local community. The fund will be made available from the time that commercial operations start and will be administered as agreed with the local communities. Further details will follow once the fund is established.
