A public exhibition is being held about plans to fit special 'harmonic filters' to an electricity substation.

The 18m-high devices need to be added to the Salle Electricity Substation, where power from Sheringham Shoal wind farm is transferred to the national grid.

Work will be carried out between the first week of February and the end of November. The exhibition is being held at Cawston Village Hall on Wednesday, January 21 (11am - 7.30pm).

Bjørn Mo Ostgren, general manager of the wind farm, said: 'We extend a warm welcome to everyone to drop in to the exhibition on 21st January, to give us the chance to explain the reasons behind this very necessary operation and to reassure them that we will make every effort to minimise the effects of the installation work on local residents.'
