New Clement steel windows for Scottish site of national architectural importance

The Lanark Hydro Electric Scheme is a remarkable project. When it was completed in 1927 it was the first of its kind in the United Kingdom. The Scheme refers to two hydroelectric plants in Clydesdale, South Lanarkshire, Scotland: Bonnington and Stonebyres’ Power Stations. They both take water from the beautiful Falls of Clyde. Bonnington’s water comes from just above the Linn in New Lanark and Stonebyres from above Stonebyres Linn near Kirkfieldbank.

The abundant supply of water from the River Clyde continuously spins the power stations’ turbines providing a reliable and sustainable source of renewable electricity. Combined, they create enough electricity to power over 17,000 homes in the UK.

The two stations have been exquisitely refurbished by our client Drax, who acquired them as part of a £702 million deal. Both Bonnington and Stonebyres are category ‘A’ Listed Buildings, the highest possible grading, as a site of national architectural importance. This means it was imperative the new steel windows were as close a match as possible to the originals.

The Clement W20 steel window range with genuine T bars, was chosen for the two Power Stations. Polyester powder painted in striking RAL 6005 Moss Green. Lodsworth handles complement the windows with matching peg stays in Antique Bronze finish. Clement made around 120 steel windows for the projects, including nearly 400 individual fixed lights, but the most beautiful is perhaps the enormous curved head windows on both sides of the buildings, which look spectacular and let in masses of natural light.

Drax Group senior civil engineer Anne Kerr said “We are delighted with the service and quality of windows supplied and fitted by Clement. The new steel windows fitted in the refurbished building look stunning and exceed our expectations."
