Scottish Hydro Electric Transmission (SHE Transmission) and SP Energy Networks have completed a project to develop a 220km power line between the Highlands and the Central Belt.

The 400 kilovolt overhead Beauly-Denny line is supported by 615 steel towers and replaces over 800 pre-existing 132 kilovolt towers built in the early 1950's.

More than 2,000 jobs were created during the projects seven-year period.

Simultaneously, wires were renewed on the main existing overhead line between the Highlands and Aberdeenshire.

So far, the new line as enabled the connection of 80 additional wind, hydro and solar generation developments in the north of Scotland.

Pearse Murray, Transmission Director at SP Energy Networks, said: "This is one of the most important upgrades to Scotland's electricity infrastructure in over half a century. A team of more than 2,000 people have come together to successfully deliver this project on time and on budget. Beauly to Denny will support Scotland's ambitious renewable energy targets, and will serve the entire country for at least the next 60 years."

Dave Gardner, Director of Transmission at SHE Transmission, added: "The full energisation of Beauly-Denny represents an extraordinary achievement by a cast of hundreds who have worked all year round, often in challenging conditions, to get the job done. It is a remarkable feat of engineering and a testament to their commitment and skill."

The north-south spine of Scotland's electricity network is the longest transmission line to be built anywhere in the UK in recent times.
