  • EDA seems the ideal partner because the people are concerned about their islands and well aware of their dependence. Therefore they are already maximizing the use of renewables. Together with EDA we identified Graciosa as the ideal candidate, because it has good wind and sun resource and no other options like hydro or geothermal. This is an overview of the islands main characteristics. 1200 people plus tourists consumed about 5.3 GWh in 2004 and will approximately consume 6.7 GWh in 2008 which we took as the base year for our calculations. The load peaks in summer which fortunatly consides with the renewable energy potential on the island
  • There engines might look familiar to you. This is the main source of electricity today. 85% of the islands needs are generated by CAT diesel generators

    • 2. Graciosa Island ( Azores)Inhabitants: 4500Area: 67 km2Peak load: ~ 3 MWElectricity consumption:~14 G h WEnergy supply:Fossil fuels (85%)W power (15%) indLocal Utility: EDA
    • 3. Graciosa’s current power system Power station 4200 kW (Fuel consumption ~ 4 Mio. l/ a)
    • 4. Adios supertankers, ahoy energy autonomy
    • 5. Project Graciosa: 70-80% renewables
    • 6. Island Test SiteTo address technical issues in island projects, we set up the Island Test Site to simulate upto 100% renewable energy systems. The grid based system can be configured to use wind,irradiation and load measurements from anywhere.
