The world’s first megawatt-scale renewable energy plus storage system, currently being built on the island of Graciosa in the Azores (Portugal), will set new standards for islands worldwide. Furthermore, by stabilizing the grid without the rotating mass of a conventional thermal engine, the system will enable the grid to be fully powered by wind and solar energy. The centerpiece of the system is a fully automated, intelligently managed 2.8 megawatt battery park integrated into the intelligent energy management system developed by Younicos. In addition, the system will incorporate wind (4.5 MW) and solar (1 MW) power resources, and intelligent inverters. The renewable energy-powered grid will boost the island’s annual share of renewable energies, from a previous limit of 15 percent to up to 65 percent and thus allow the island to reduce its dependence on fuel imports.
