PV-Diesel-Hybrid-System St. Eustatius, Karibik

Large-Scale Island Electrification, St. Eustatius

Hybrid Energy System – NL Antilles, 2017

Today, solar energy covers 46% of St. Eustatius’ total electricity need. Grid Forming SCS 2200 inverters allow to operate the island grid for 10.5 hours in Diesel Off-Mode operation with 100% Solar Power Fraction. In total a 5.9MWh Li-Ion storage facility has been integrated for energy shifting and grid services. Thanks to the SMA Fuel Solution about 4,560 tons CO2 per year can be saved. The project has been designed, and implemented by the SMA Sunbelt Energy GmbH.
