Infrastructure group Balfour Beatty has won a GBP290m ($465m) transmission line deal that forms the bulk of the controversial Beauly-Denny project in Scotland.

The Beauly-Denny scheme will see overhead lines between Inverness and Stirling replaced, with work to remove the first of 300 pylons beginning last month. Most of the 220 km line is owned by SSE, with Scottish Power responsible for 20 km.

Balfour Beatty has been awarded the contract by Scottish Hydro Electric Transmission, a subsidiary of SSE, to replace the line between Beauly and Wharry Burn, which is 20 km north of Denny.

The contract involves the development, design, provision and installation of a 200 km double circuit, 400 kV overhead electricity transmission line to replace the existing 132 kV line, with work set to be completed in 2015.

The project is being carried out to link Scotland’s growing number of renewable energy projects to the national grid. Mike Sparrow, Balfour Beatty’s utility solutions managing director, said the contract “will ensure Scotland has the robust electricity network necessary to enable it to become a European leader in decarbonisation, through connection of its targeted growth in renewable generation”.
