The reservoir was created by the flooding of marshlands in 1966 and it supplies 35 million litres of water a day to the northern half of the island. Llyn Alaw Wind Farm is situated to the north of the small village of Llanbabo which is close to the reservoir’s eastern shore.
Construction work on Llyn Alaw Wind Farm began in 1996 and it opened in October 1997. The site, which was originally developed by West Coast Energy, has 44 turbines rated at 600kW, giving the wind farm an installed capacity of 20.4MW and the ability to generate enough energy to power 11,324 homes*.
