In early 2004, the UK's largest and most powerful (at that time) wind turbines were installed at three sites across County Durham. Holmside, Harehill and Highvolts, collectively known as 3H's, were commissioned in Spring 2004.

Construction began at the end of July 2003. A locally based company, AMEC Wind Services, initially developed the site and also provided project management during the construction phase. In October 2003, the wind turbines were delivered by ship to Hartlepool docks and then transported in sections by road to the sites in delivery vehicles up to 50m long - around the length of five London buses.

The wind farm at Holmside generates enough renewable energy to supply nearly 3,000 homes and displace the emission of over 11,000 tonnes of carbon dioxide.

Putting the Holmside Turbines into Perspective...

Here are some well-known tall structures, in comparison with the turbines at Holmside Wind Farm:

• Nelson’s Column - 56m high.
• 3H turbine hub height - 60m.
• The Rotunda (Birmingham) - 81m.
• The Statue of Liberty - 93m.
• Big Ben - 96m.
• 3H turbine height to blade tip - 100m.
