Construction is underway on a fully automated 3.2 MWh intelligent battery park on the Portuguese island of Graciosa in the Azores, according to intelligent energy storage grid solutions provider Younicos. The Berlin-based company provides software for grid-connected battery storage, which includes optimizing solutions for solar-diesel hybrids. The planned system will use lithium-ion cells from Leclanché, and will allow the island to be powered by wind and solar energy.

This will allow the island to replace two-thirds of its fossil fuel needs with renewable energy. Fossil fuels will only be needed for back-up power during prolonged periods of unfavorable weather. A 1 MW photovoltaic power plant has already been installed, and is supplying power to the small island. A 4.5 MW wind park is currently being installed. These will be supported by an automated 3.2 MWh intelligent battery park that will balance short-term power fluctuations.

A Dutch renewable energy investor has acquired a 50.1% stake in the project, valued at €24 million ($26.6 million).
