A two year, £70m scheme to upgrade a high-voltage electricity line across north Wales will start this summer, National Grid (NG) has said.

Equipment will be replaced on 200 pylons along a 40 mile (64 km) route between Trawsfynydd, Gwynedd, and Treuddyn in Flintshire.

NG says fittings like insulators and cables are coming to the end of their working life.

About 70 engineers will be involved and power will not be disrupted, NG says.

The existing electricity line has been supplying power since 1961, but is coming to the end of its operational life.

New pylons will not be needed, NG says, and the project is expected to be completed by late 2014.

Phillip Roberts, of Electricity Alliance, a partnership between NG and construction companies, said: "The work on the Trawsfynydd-Treuddyn overhead line is part of our scheduled national maintenance programme.

"It will ensure we can continue to provide reliable electricity supplies across the region and the country as a whole, now and for the future."
