Abstract

The principal aim of this project was to demonstrate that in a site with a medium wind speed of c. 5.5 m/sec. not fed by the national grid, it is possible constantly to feed consumers with industrial needs, using only electrical or thermal renewable energy produced by wind generators and co-generators. Three wind-turbines of 42 kVA each have been installed in a fish farm near Marsala (Sicily); one of them operates in parallel with a gas co-generator while the two gas co-generators with the other two WECs are in parallel with a national electric grid. The electricity and the heat are used for the energy needs of the Italittica fish farm. In the context of the project three horizontal-axis, upwind turbines, manufactured by Aeroman-ISEA with a nominal power of 33kW each and three gas co-generators manufactured by Teledyne-ISEA with a nominal power of 30 kW electric and 40 kW thermal each, were installed and commissioned in two months. During the eight months of the demonstration phase the plant produced 279 280 kWh of electrical energy and 282 960 kWh of thermal energy with an investment cost of LIt 613 million and a saving of LIt 28 million per year; therefore the pay-back period will be 22 years. The cost per energy unit is LIt 61 for the aeolic kWh and LIt 61 for the co-generation kWh. The same plant, but in isolated areas, that is to say not connected to a national electric grid, could cost LIt 450 million with a cost saving of LIt 50 million each year, therefore in this case the pay-back period could be nine years, i.e. the same as the initial appraisal of this project.
