The contract involves Amey refurbishing and renewing 92,000km of overhead power lines across WPD’s network until 2018.
The network serves the South West, South Wales and Midlands regions and is the largest in the UK, providing 7.8m customers with electricity.
The contract builds on an existing relationship that has involved Enterprise providing services across some of WPD’s network since 2003. Amey acquired Enterprise in April 2013.
Amey chief executive Mel Ewell said: “This latest partnership with Western Power Distribution builds on a successful period for Amey across the utilities sector and we are pleased that the utilities proposition formed off the back of our Enterprise acquisition earlier this year has been received so positively by our customers.”
In recent weeks Amey has also won contracts with Welsh Water, United Utilities and Severn Trent Water to provide clean and waste water services.
In other markets, Amey has won a further seven highway maintenance contracts with Gloucestershire County Council, Liverpool City Council, Transport Scotland, the New South Wales state government agency in Australia, the Queensland Government Department in Australia and ASC 6 and ASC 8 with the Highways Agency.
