CONSULTANT JOHN Large ignored advice about the location of a wind turbine, which then only produced 27p worth of electricity in three weeks, installer Sundog said this week.
The installer and manufacturer of the turbine said Large was warned that his site was unsuitable for the effective use of the wind turbine he had ordered and that the height of the mast was too low.
They were hitting back at Large's criticisms of the Proven Energy WTR2500 installed at his Woolwich Common premises in south east London (News last week).
'Sundog made clear on several occasions our serious reservations about the suitability of Mr Large's site for the proposed wind turbine, ' said Sundog director Ali Ross.
'We expressed concern both about wind speed at the site and the numerous trees and buildings in the close vicinity that would adversely affect the output and performance of the turbine. We also stated that we did not consider that the 6.5m mast speci ed by Mr Large would be adequate in this situation and that even an 11m mast may not be tall enough to overcome the effects of obstacles, ' said a Proven Energy spokesman.
We very specically explained these concerns by both email and by telephone to Mr Large and gave him the opportunity to withdraw his order, which he declined to do.' Large refuted the idea that his site was not windy enough, 'I've had my roof blown off twice so I know how good the wind is here', he said.
Sundog managing director Martin Cotterell said that urban conditions were often inappropriate for wind turbines because turbulence caused by surrounding buildings makes it dif cult to harness the wind power.
A Proven Energy spokesman added: 'Our turbines perform exceptionally well in windy conditions such as the North Sea, the Arctic and the Saudi Arabian desert.'
