Extremely high winds have once again been recorded at Cemmaes wind farm in mid-Wales. Gusts of up to 59.5 m/s were recorded on December 8 -- one year to the day when storm force winds caused havoc among the site's 24 WEG turbines. In December 1993 strong gusts destroyed the rotors of four turbines and damaged several other machines. The manufacturer of the turbines, the Wind Energy Group, has since carried out a retrofit to the pitch linkage system of all its MS-3 turbines which have a designed survival wind speed of 60 m/s. In contrast to the damage sustained a year ago, all WEG machines at Cemmaes survived this year's blast unscathed.
