Wind Turbine 4G Interference

Case Study 17: Wind Turbine Development, England

Pager Power looked into a new wind turbine development in South Yorkshire when local residents complained of television (TV) reception interference. Following two Post-Construction Television Reception Surveys, it was still predicted that the wind turbines were unlikely to be the cause. After conducting a further Television Interference Investigation, Pager Power concluded that 4G signals were much more likely to be the cause of the TV reception interference. This finding removed the wind developer’s obligation to provide costly mitigation solutions, and potential future issues with the local planning authority.

MoD Radar Wind Farm Case Study

Case Study 05: New Albion Wind Farm, England

Virtually unobstructed; 30km from the Primary Surveillance Radar (PSR) at RAF Cottesmore to the proposed wind farm, there were potentially significant planning issues. This was later to be confirmed by the Ministry of Defence (MOD). Incorporating all factors into their line of sight model we were able to determine that the height of the radar relative to the turbines, combined with the distance, the earth’s curvature, and likely radar signal attenuation meant that radar detection would be marginal at worse. The MOD withdrew its concerns.

Wind Turbines & Unmanned Aerial Systems (UAS)

Case Study 04: Pen Y Bryn Wind Turbine, Wales

We were involved in a wind turbine public inquiry in Wales regarding interference caused by wind turbines on Unmanned Aerial Vehicles (UAVs). Following the public inquiry the wind turbine was given the go ahead and is now operational. The appeal was quite unusual because the turbine was small and had already been built. Situated next to the runway at West Wales Airport where Unmanned Aerial Vehicles are tested, the turbine was also in range of MOD radar at their Aberporth test facility run by QinetiQ.

Offshore Radar Case Study Sheringham Shoal Wind Farm

Case Study 02: Sheringham Shoal Wind Farm, England

The proposal for 88 offshore turbines in an area where low flying military fast jets operate, not surprisingly, was the cause of some concern. The operator of Cromer secondary surveillance radar (SSR) objected on the grounds that there would be a technical impact on the radar, and the development was stopped. Using our custom built software, we were able to assess radar detectability and the shielding effect of the towers. We determined it highly unlikely that low flying aircraft would not be detected as a result of the wind farm. Wind farm and radar now safely coexist.
