The performance of locally manufactured small wind turbines is rarely measured, let alone with any degree of accuracy. This study is the first in a series that aim to use the international standards for power performance testing to obtain reliable measurements of the behaviour of these machines. A 1.8m diameter machine was monitored for 4 months on the Scottish peninsula, Scoraig, and a power curve produced. Peak power for the machine was found to be 267W at 13.5m/s and the rated annual energy production (on a 5m/s average wind speed site) is predicted to be 495kWh. Results are in strong agreement with wind tunnel tests performed in a separate study, up until furling begins.
