Thanet Extension Offshore Wind Farm

Received 12 September 2018
From Ministry of Defence


I write to confirm the safeguarding positon of the Ministry of Defence (MOD) in relation to the above application to construct and operate the propsoed Thanet Extension Offshore wind farm.

I am writing to tell you that the MOD has no objection to the proposal.

The application is for 34 turbines at 250.00 metres to blade tip. This has been assessed using the grid references below for the boundary outline as based upon the coordinates detailed in the application documentation:

Turbine Easting Northing
1 656,669 181,338
2 658,777 179,199
3 656,879 170,961
4 650,579 171,197
5 649,998 171,787
6 648,983 172,817
7 646,312 175,599
8 646,432 179,616
9 647,608 180,705
10 652,279 173,381
11 656,466 173,384
12 656,342 175,996
13 652,489 179,863
14 650,119 179,748
15 648,019 177,656

The turbines and some of the associated tall ancillary offshore structures will affect military low flying training activities conducted in this area. As such it will be necessary for these structures to be fitted with appropriate aviation warning lighting to maintain the navigational safety of military aviation.

The MOD has assessed the effects of the proposed wind farm development upon the effective operation of its air traffic and air defence radars. It has been confirmed that the proposed wind turbines will not be in line of sight or detectable to MOD air traffic radars and are not expected to impact upon the operation of air defence radars. However, the MOD has recently identified that in certain conditions the performance of air defence radars may be adversely affected by large scale offshore wind farm developments when they become operational. Based upon the technical evidence currently available the MOD does not identify a need for any form of mitigatory measures to address this potential issue to be implemented in relation to the scheme for which consent is currently sought.

If consent is given the MOD will need to be advised of the following prior to commencement of construction;

• the date construction starts and ends;
• the maximum height of construction equipment;
• the latitude and longitude of every turbine.

This information is vital as it will be plotted on aviation charts which are used in the management of military low flying activities conducted in the area.

I hope this adequately explains our position on the matter. If you require further information or would like to discuss this matter further, please do not hesitate to contact me.
