By the late 90s we realised that it was possible to connect more capacity than had been shown in our initial studies for Haverigg I, so the idea of repowering was born. It took a few years to obtain planning consent, secure a connection and obtain a Power Purchase Agreement, but by 2004 everything was in place and construction commenced. The project was commissioned in February 2005.
The Haverigg 3 windcluster uses four Vestas V52 turbines, with a total rating of 3.4 MW. The V52 is one of the workhorses of the industry, with many thousands in operation around the world. They are elegant, efficient and quiet, mixing established design with advanced composites and control systems.
They were selected after detailed landscape and technical assessments. While they are larger than the five V27's which they replace, the overall visual effect is not much changed. They turn more slowly so are more restful to the eye and from a distance appear to be very similar to the four Haverigg II turbines which have remained on the airfield.
Pulling together a project like this requires help and support from many people and organisations. The planning application was prepared by Wind Prospect Ltd with assistance from specialist consultants Woolerton Dodwell Associates, ACIA and SGS Environment.
The wind speed and energy yield were calculated by Garrad Hassan from the original measurements made in 1990 and the long term records from Haverigg 1.
Econnect Ltd advised us on the electrical connection and we worked with United Utilities to make it a reality. Vestas supplied the turbines and appointed Wind Prospect to manage their installation. Triodos Bank provided the debt financing and the remainder of the money came from our faithful shareholders. CO2e helped us to find our Power Purchase Agreement with Centrica and we received valuable legal advice from Wrigleys and Osborne Clarke.
