Plans to build a wind farm at a Powys beauty spot could deter tourists visiting, according to campaigners.
Hendy Wind Farm Ltd said its proposal to build seven turbines at Llandegley near Llandrindod Wells had the support of land owners.
The planning committee has been recommended to approve it on Thursday.
Four of the turbines could be built on a protected public right of way, according to preservation body the Open Spaces Society.
This could make it common land, according to the group set up in 1865 to protect such areas.
Plans would see seven turbines built that would provide energy to power about 10,000 homes.
Kate Ashbrook, general secretary of the Open Spaces Society, called the development “damaging”.
“People visit the area because of its natural beauty, peace and tranquillity,” she said.
“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.”
