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.
