WIND DIESEL ELECTRICITY SUPPLY FOR ANHOLT ISLAND

Obiettivo

To demonstrate that a mass produced standard wind turbine can be combined with diesel generators in an isolated electricity supply system and contribute to the energy supply of the area. The savings in fuel, the economy of the combined system and the reduction of the pollution shall be evaluated. The estimated yearly energy production is 70,000 kWh or equivalent 19 TOE.
The wind turbine was installed in January 1989 and was in operation in March 1989. During a total period of 20153 hours, it produced 116421 KWh. The availability of the system was low (about 58%) due to a damage caused by lightning and the operational limits imposed by the local utility. The project now is ripe for commercialisation.
A mass produced standard wind turbine has been connected with the diesel generators of the island of Anholt (Denmark) in order to contribute to the 660 KW (1 x 160 + 2 x 250) installed power of the local grid and to evaluate the savings in fuel, the economy of the combined system as well as the reduction in pollution. The wind turbine has a nominal power of 55 KW and the mean electricity production at the site is estimated to be 100 MWh/yr.
Due to the combination with the diesel generators the annual yield is expected to be reduced to 70 MWh. The total estimated diesel fuel saving is 19 Tons per year. The estimated payback period is 14 years. The cost per KWh is 2.74 DKR/yr while the cost of the diesel generated KWh is 1.88 DKR/yr.
Remarks : the percentage of the dumped energy is 30% which seems to be high enough. Maybe a different way of combining the wind turbine and the diesel generators could show better results.
