This report summarises operating experience and analyses the economics of a small grid-connected wind turbine generator. The analysis is based on 33-month performance data from the demonstration project on the Shetland Islands, to provide wind generated electricity to tourist, isolated and island communities. A Vestas 55 / 11kW, 15m rotor diameter wind turbine generator was installed and has been operating satisfactorily. A user oriented approach is adopted to calculate the cost savings as a direct result of installing the wind turbine. The implications for the special terms of supply of electricity to small private generators by the electricity authority in the area are considered. A comparison is made with various tariff structures operated within the Board's diesel and non-diesel areas for domestic, farm and general consumers. Availability of the machine over the reporting period was over 97%. During this period the WTG produced a total of 368,103 Kwh of energy. At the nearby Lerwick Meteorological Station the average recorded annual wind speeds in 1986/7 were 7.42 m/s and 6.51 m/s respectively with the long term average of 7.19 m/s.
