A company behind a small wind farm in south Powys is appealing against a decision to refuse planning permission.
Protesters won an eight-year campaign to prevent three turbines, standing at 91m (298ft) tall, from being built at Pentre Tump, near Presteigne.
The original application was submitted in 2002, but it was finally rejected by Powys council at a meeting in February.
Visual impact on the landscape and the effect on public rights of way were among reasons for refusal.
Applicant Cornwall Light and Power said at the time it was "naturally disappointed".
Announcing plans to appeal, the company's development manager Bob Morgan said: "We remain convinced that Pentre Tump is the best site in Powys for a small wind farm and would be happy to discuss with any interested parties why we believe this is the case.
"I've offered to meet with each of the community councils and most local residents to discuss our plans and explain the considerable benefits of the scheme."
If successful in its appeal, Cornwall Light and Power's proposed scheme would meet the energy needs of more than 2,000 homes in Powys.
The council said in February that the development would have an "unacceptable adverse impact on the public rights of way network" and a "visual impact" on the surrounding area and landscape.
There were 979 letters and e-mails, and three petitions with 302 names objecting to the proposal.
But the council also received 58 letters of support for the project.
