NVE has decided to rectify and stop the Vardfjellet wind farm, due to disruptions in the digital terrestrial network for TV.
Shortly after the first turbines in the Vardafjellet wind farm produced electricity, reports were received by RiksTV and NTV about disturbances in the signals. NVE has also received notifications from end users about disturbances.
Norges Televisjon AS (NTV) is a licensee for the digital terrestrial network for television. NRK and RiksTV are distributed on this platform.
Plan to recover the signals
On behalf of NTV, Telenor has carried out measurements that confirm that there are disturbances in the digital terrestrial network due to interference from the wind power plant. The report specifically points to two turbines as the cause of the disturbances. On 30 September 2020, NVE sent a notification of a decision on rectification and shutdown to the Vardafjellet wind farm. On 20.10.2020, NVE received a response to the warning, with an action plan to restore the signals.
After an assessment of the action plan and NTV's input in the case, NVE decided to rectify and stop due to disturbances of the TV signals during the establishment of the Vardafjellet wind farm.
The decision states the following:
The licensee shall, in collaboration with NTV, establish two new permanent DTT broadcasting stations as soon as possible to ensure end users access to the digital terrestrial network.
The licensee shall, in collaboration with NTV, as soon as possible establish temporary solutions such as broadband or satellite for end users who are affected by interference from the wind turbine. Temporary solutions must be in place by November 6, 2020 at 12:00. The temporary solutions will be removed when the permanent DTT transmitting stations are operational.
If the temporary solutions for end users are not in place by November 6, 2020 at 12:00, the licensee shall immediately stop turbines 1 and 3. The turbines shall be shut down until temporary solutions have been established at the end users who are affected by interference. NVE may order further shutdown of turbines if shutdown of turbines 1 and 3 is not sufficient to restore the TV signals.
The entire decision on rectification and stoppage , as well as other important case documents for the Vardafjellet wind farm, can be found on NVE's website.
