THE FUTURE of microgeneration was thrown into question this week after one engineeing consultant calculated that his newly installed wind turbine would take 2,457 years to pay for itself.
A row is ongoing between London based engineering consultant Large & Associates and wind turbine installer Sundog after the consultant generated just 27p worth of electricity in the first three weeks of operating the new turbine at its Woolwich Common premises.
Sundog installed the £11,500 Proven Energy WTR2500 wind turbine early last month.
Disgruntled Large & Associates director John Large said: 'We went through a great deal of bureaucracy to install this unit - planning, grant applications, deals with the electricity supply company - and, the result for all of this hufng?
- very little puff.
'To date, over three weeks and including the storm two weeks ago, we have generated just over 27p of electricity.
'There are several sets of performance characteristics here - the turbine has to be matched to its wind performance, that [matched] to its generator, then [matched] to its power control unit to stop it stalling at low wind velocities, and then to the grid connect inverter to protect the grid - the result seems to be a real mishmash of transfer functions.' roven Energy business advisor Peter Tindt said that the expected loss of energy between the turbine and the National Grid should be no more than 10%. The company is now investigating the wind speeds powering the turbine in January.
Tidnt added 'typically the turbine is vastly better than this; it loves wind and is extremely robust. It is either badly located or badly installed.' Sundog declined to comment.
