The March/April 2006 edition of
Renewable Energy World magazine carries
a project profile of
Beaufort Court - RES's headquarters building, with its wind turbine,
at Kings Langley, just alongside the M25.
It notes that the wind turbine, a 36 metre high 225 kW Vestas V-29 was bought second hand from a wind farm in the Netherlands
for £140,000 (206,000 Euro).
