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 the island grid to operate in Diesel Off-Mode for up to 10.5 hours, using electricity supplied by the connected PV system and battery storage. In total a 5.9MWh Li-Ion storage facility has been integrated for energy shifting and grid services. The system combines photovoltaic generation, battery storage and automatic generator shutdown to reduce diesel generator operating times. The project has been designed, and implemented by the SMA Sunbelt Energy GmbH.
