Windflow Passes Major IEC Milestone
All of the documentation for IEC certification of the Windflow 500 turbine has been submitted to Lloyds Register, the
certifying body based in the UK. The final document was lodged at the end of July for review by Lloyds Register, which
is likely to take a few more months.
Windflow has provided its customer, NZ Windfarms, with regular reports on the progress towards this and on the minor
design improvements made in order to meet the IEC requirements. There are no known issues to prevent certification of
the latest version of the Windflow 500.
The five Stage 1 Windflow 500 turbines have been operating at NZ Windfarms' Te Rere Hau wind farm site near Palmerston
North since September 2006 and in the following years NZ Windfarms placed orders for a further 92 turbines for this wind
farm, knowing at the time of each order that the work required for IEC certification had not been completed. As a result
the turbines installed at and under construction for Te Rere Hau are slightly different from the latest version
submitted for certification.
The Windflow 500 turbines supplied and being supplied for the Te Rere Hau site are fit for purpose and Windflow
Technology is working with NZ Windfarms to demonstrate that fact. More than 50 turbines have been commissioned at Te
Rere Hau and they are meeting or exceeding their warranted availability and power output.
