Increased Light Pollution?
Viking Energy has received approval to increase the size of the proposed 103 Turbines it hopes to erect across the central mainland. Instead of 145 m it plans to increase them to 155 m tall and also increase the height of the rotas by 5 m to keep within the 35 m ground clearance. The rota diameter will also increase by 10 m to 155 m. The M.O.D have made an objection to this increase but I am not sure whether they have followed this up.
This is bad enough for any landscape photographers but for astrophotographers in Shetland it will mean a red glow from the warning lights at the top of the turbines so an increase in light pollution. You can see this from the 2 photos showing Burradale wind farm just outside Lerwick.
If the Viking wind farm gets the ok with the next bids, (confirmation due out soon) the floodgates will open and we will see 180 + new turbines erected in Shetland, which will all add to the red glow in our skies. So not just the central mainland but also in Yell, and down to Cunningsburgh in the south mainland.
The glow from the flares at Sullom Voe has already destroyed the dark site in the north mainland, its glow even can be seen from Eshaness on the west coast.
I have spoken to many visitors who come to Shetland to escape the turbines that blight the landscape in the south, they come north to see un-spoilt landscapes, wildlife and the chance of an Aurora or seeing the milky.
Wind Turbines , its a big no from me on so many counts. We don't want too loose our chance to see or photograph the stars or Aurora. There is every indication the red glow from the warning lights on the turbines in the central mainland will spoil the view north from Tingwall, in fact they will be seen around 25 miles away
Here is the full list of turbines so far, erected (in place) and the rest proposed
- 5 above Burradale (in place)
- 103 Viking Central mainland (155m) 13.3% of the mainland
- 29 Energy Isles , Yell North West (200m) 10.5% of Yell
- 17 Peel Energy Yell Beaw Fields (145m) 5.3% of Yell
- 5 Nth Yell Council, Yell , Garth (In place)
- 12 Peel Energy Mossyhill (Lerwick- Scalloway)(145m) 1% of the mainland
- 15 Bridge end, Burra
This is virtually a 70km unbroken chain of wind turbines. Total wind farm footprint area(On active peat bog) 172.42 Sq Km, total area of Shetland 1468km, that's 11.7 % of the total land area of Shetland. (Allen Fraser)
EIA Report Viking Energy November 2018
4.8.1 A review of the proposed varied development has found that there would be no changes to the degree of landscape and visual effects (including cumulative landscape and visual effects) between the consented Viking Wind Farm and the proposed varied development excluding the effects of turbine lighting.
Effects of Turbine Lighting •
An assessment of turbine lighting undertaken for 13 viewpoints identified that the visual effect of a medium intensity light on every turbine, as required by CAA guidelines, would be significant from all but one of the VPs considered. Those VPs receiving significant effects are within 10 km of the proposed varied development with VP5 (Knab Road, Lerwick), located over 15 km from the proposed varied development, being the only VP likely to be not significant. It was therefore concluded that when taking turbine lighting into consideration, the inclusion of a medium intensity light on every turbine would result in significant effects during low light and night time conditions.
However, the Applicant proposes to engage with aviation stakeholders to agree a lighting solution which may result in a reduced visual effect. Discussions would include consideration of the following: Potential reduction of lighting intensity during good meteorological visibility; (No update as yet)
• Radar activated lighting (should this be approved for use); and
• Potential for cardinal or strategic lighting on selected turbines.

Work on the Viking Wind farm started on 18 July 2019 with (https://www.shetnews.co.uk/2019/07/18/wind-farm-ground-investigation-work-gets-underway/) with ground investigations , however construction type activities have taken place (Roads ) without full planning permission.
If they get the Government funding and the inter connector goes ahead they expect to finish by 30 June 2024.
The Yell Wind Farm will have turbines 200m high to the blade tip, that's higher than the cliffs of Noss. Again these will have red aircraft warning lights fitted.
So viewing the Aurora, milky way or stars might become a thing of the past in these areas and to areas where the red light spreads, which is about 25 miles away.
Some of the spots I use will be affected and you have to feel sorry for Aurora Hunters in the north Mainland and in Yell.

Why not participate in the Globe at Night campaign, its a great way to help our understanding of Sky glow and its impact. No special tools required and observations can be easily reported by Smartphone or computer.
Its also possible to use a smartphone to make night sky measurements. The Dark Meter App makes use of the iPhone camera to record the brightness of the night sky, while Loss of the Night app walks the user through the sky as measurements are made.
