Plans to remove a section of overhead pylons in Dorset's Area of Outstanding Natural Beauty (AONB) have been approved.
National Grid will remove 22 pylons along a five-mile (8km) stretch of the county near the villages of Martinstown and Winterbourne Abbas.
Overhead power lines will then be buried in the area.
The aim is to reduce their visual impact on the AONB, according to the utility company.
The plans, which were approved by West Dorset District Council, are subject to a legal agreement to secure money for ecological and landscape enhancements.
The preferred route of the underground cables was designed to avoid properties and known archaeology, National Grid said.
The work is expected to take up to three years to complete.
Dorset's AONB was designated in 1959 and covers just over 40% of the county, from Lyme Regis to Poole Harbour and inland as far as Blandford Forum.
