From P. Browne, Electricity Corporation of New Zealand
Last year the Electricity Corporation of New Zealand (ECNZ) erected a Vestas V27 225 kW turbine on the hills overlooking the capital city of Wellington for research and demonstration purposes. It was commissioned on March 11 and took a year and three days to generate its first million kWh. Bearing in mind that commissioning tests interfered with generation in March last year, it was decided to measure output over the year ending March 31 1994. The millionth kWh was generated today, March 28, with three days of the year to spare, giving a capacity factor for the year of over 51%. From contact with Vestas in Denmark it appears this may constitute a world record for a 27m diameter fixed speed variable pitch horizontal axis wind turbine and we should be interested if any readers can confirm this or, alternatively, inform us of a better result.
