Wind Prospect

Powys wind farms: Pentre Tump, Mynydd-y-CEMMAES refused
Schemes for 12 turbines at Mynydd-y-CEMMAES, near Llanbrynmair, and three at Pentre Tump, near New Radnor, were recommended for refusal.

Proposal for turbines revealed
Acciona Energy has announced today (june2007) it intends to submit planning applications to Powys County Council for permission to generate electricity from wind at Waun Garno and Mynydd y CEMMAES.

Fears over more windfarms
Acciona Energy UK wants to construct 23 turbines at Waun Garno windfarm, near Trefeglwys, and Mynydd Y CEMMAES, near CEMMAES.
