Maesgwyn wind farm is located 2-3kms to the north east of Glynneath in Neath Port Talbot County Borough, on the site of several former opencast mines. The site is located within TAN 8 strategic search area E (SSA E).
The site received planning consent in 2008, construction commenced in late 2009 and was completed in mid-2011.
Because of the mining history of the site, ground improvement works were required ahead of construction of the wind farm on opencast backfill materials. The wind farm has a remaining operational life of 19 years.
The wind farm comprises 13 Alstom E80 2MW turbines, which are a mix of 70m and 80m hub heights, which are the most suitable for the rugged topographical conditions on the site. The site can produce up to 26MWe, which is the equivalent of the energy required to supply 12,000 homes. Alstom provide an operation and maintenance service and Pennant Walters provide site management and reporting services.
