Deployment of the wind
Sweden (2007) : 1 % of the country’s net electricity consumption
Corresponds to 1.4 TWh
Political decision (2002):
Production of 30
TWh prior to 2020
Germany: 7,5 % (Source: GWEC, Global Wind Energy Council)
Spain:
11 %
Impact on radiosystems
Conducted studies confirms that fixed systems like Radar-, RadioRelay,
Brodcasting-systems and RAS may experience disturbances due to
obstruction and/or reflection caused by turbines.
In the case of Radars, shadowing and/or reflexions is the main problem
when considering off-shore windturbines vs coastal surveillance radars.
The potential for these disturbances depends on the size of the turbine,
material, location in relation to the ”victim” etc
 For RAS, even EMC caused by the generator may cause disturbance in
case the separation distance is not sufficiently large.
Protection
Exclusion zone around the RAS-site may provide
sufficient protection if the zone is large enough.
Guidance on this zone, given by international
recommendation(s), would be useful?
Responsibility of the Swedish agency
 Provide, to the operator of wind turbines, a list of potentially
concerned operators of radiosystems in a certain geographical area.
The intention with this procedur is to establish a ”marriage” between
concerned operators with the objective to create a fruitful environment
for coordination.
 It should be noted that the agency is not responsible for the licensing
of turbines. This issue is handled by the local authorities.
The agency is responsible for the protection of radio services only.
Web-site Vindlov (www.vindlov.se)
- Swedish Energy Agency responsible for this site
developed in cooperation with 20 authorities
(incl the telecom agency)
- The objective is to provide information covering all
aspects of the complicated process of licensing
Permission/licensing process
-Classification of wind turbines
