Stirling-based Windflow has introduced its new 45-500 turbine design to the UK market following installation and operation of the first prototype in Texas, USA.
Windflow UK is part of the New Zealand-based, publicly-listed Windflow Technology group, which has more than 500 turbine-years operating experience with the predecessor 33-500 turbine, one of which was installed at Hammer Farm on Westray in the Orkney Islands two years ago.
Windflow’s first UK project, the 33-500 turbine was successfully installed in one of the most remote parts of the UK, with a severe wind regime in the middle of winter storms.
The new Windflow 45-500 has a 45m (148 ft) rotor diameter and sweeps out an area of 1,590 square metres, equivalent to nearly one-third of a football field.
This is an 80% increase over the Windflow 33-500, and dramatically improves energy capture at low wind speeds. The Windflow 45-500 is designed for sites with average wind speeds up to 8.5 m/s.
