Powys Council is considering plans to build a wind farm at known beauty spot, prompting campaigners to warn the move could deter tourists visiting the region.
The proposal was submitted by Hendy Wind Farm Ltd and involves plans to build seven turbines at Llandegley near Llandrindod Wells had the support of land owners.
The planning committee has been recommended to approve the plans, with campaign group the Open Spaces Society warning that four of the turbines could be built on a protected public right of way.
If the move goes ahead, the construction would see seven turbines built that would provide energy to power about 10,000 homes.
Kate Ashbrook, general secretary of the Open Spaces Society, claimed the development was ‘damaging’: "People visit the area because of its natural beauty, peace and tranquillity.
"The turbines could deter them from coming and that would result in a serious loss of tourist income to the community."
A spokesman for Hendy Wind Farm Ltd said: "The proposal is of course put forward with support of all the relevant land owners, and we are comfortable that we have all the rights required for the planning application."
