The Graciosa Project Adios supertankers, ahoy energy autonomy
Basel, 21 February 2012Martin Röder
Inhabitants: 4500
Area: 67 km2
Peak load: ~ 3 MW
Electricity consumption: ~14 GWh
Energy supply: Fossil fuels (85%)Wind power (15%)
Local Utility: EDA
Graciosa Island (Azores)Graciosa Island (Azores)
Graciosa’s current power system
Power station 4200 kW
(Fuel consumption ~ 4 Mio. l/a)
Adios supertankers, ahoy energy autonomy
Project Graciosa: 70-80% renewables
Island Test SiteTo address technical issues in island projects, we set up the Island Test Site to simulate up to 100% renewable energy systems. The grid based system can be configured to use wind, irradiation and load measurements from anywhere.
