Obernau wind farm: Citizens criticize plans – first-hand answers!
The Wittgenstein Group recently held an information event in the Siegerlandhalle in Siegen, which provided information about the planned wind farm on the Obernau with a total of twelve wind turbines. Around 250 listeners came together to listen to managing directors Karl Prinz zu Sayn-Wittgenstein-Berleburg and project manager Cliff Reppel. Citizens took the opportunity to ask critical questions, especially about possible impairment of water protection zone 2.
Prince Karl emphasized that the company's responsibility goes beyond the construction of the wind turbines. He promised to reforest the forests and emphasized that over 400 leases already exist. So far, the project has been characterized as well thought out, with a clear focus on climate protection and CO2 reduction. Reppel also informed those present about the planned compensation payments to the Siegen-Wittgenstein district, the city of Netphen and the affected citizens.
Increased wind power expansion in the region
The positive response to the wind farm on the Obernau could become more important as a result of a ruling by the Higher Administrative Court of North Rhine-Westphalia (OVG). Loud wirSiegen.de The Siegen-Wittgenstein district will have to clear the way for 22 new wind turbines in the short term. This comes in the wake of the ruling that the temporary suspension of approval processes for wind turbines not located in preferred areas is likely to be unlawful.
Environment department head Arno Wied explained that it is now crucial that permits for many of these facilities are granted quickly, even without the necessary urban planning consent from the municipalities. This enables the district to issue approval notices, which can then possibly be challenged in court by the municipalities.
The current status of wind power projects
There are currently 44 wind turbines in operation in Siegen-Wittgenstein, and a further 89 systems have been approved - these are to be built in the next two to three years. In addition, 36 wind turbines are undergoing a full process under emissions control law, while 128 systems have received positive preliminary decisions and are therefore considered eligible for approval. In this regard, it is crucial for the approval authorities to follow the legal requirements, as Wied emphasizes.
The wind power companies are also working on further projects in the approval process. Loud UHL wind power The nominal output of these three new wind farms totals 79.2 megawatts. Two of these projects are so-called repowering projects, in which old wind turbines are replaced by more powerful ones.
The careful planning of these projects as well as the intensive exchange with external specialists help those responsible to look optimistically into the future and wait for the approvals with positive expectations.
