NHOA Energy has announced the commissioning of a 50-megawatt-hour battery energy storage system in Vicari, Sicily. Developed for ERG, a leading independent renewable energy producer, the system integrates modern energy storage technologies with two ERG onshore wind farms (Vicari and Roccapalumba) via ERG’s substation. The system delivers 12.5 MW of power and 50 MWh of storage capacity, enabling four hours of renewable energy availability to support grid stability and renewable integration.
NHOA Energy served as the engineering, procurement, and construction contractor, delivering proprietary power conversion systems and plant control technologies. Following handover, NHOA Energy will manage operations and maintenance under a five-year service agreement.
“This is a significant project that significantly improves the flexibility of the Sicilian power grid,” said Fabrizio Ciaccia, Vice President EMEA, NHOA Energy. “Together with ERG, we have developed a hybrid infrastructure that strengthens the reliability of renewable energy sources, the resilience of the electricity grid and the decarbonisation goals of Italy and the EU. With the Vicari BESS, NHOA Energy underlines its leading role in the transition to a more sustainable and energy-independent future.”
The Vicari project is part of broader national and European initiatives to accelerate renewable energy deployment through advanced storage solutions. It is NHOA Energy’s third installation in Sicily, following the Terna storage laboratory in Ciminna and a fast-reserve facility in Salemi. Hybrid systems like Vicari are essential for stabilizing the grid, overcoming renewable intermittency, and advancing full decarbonization of the energy sector.
Additionally, the project was featured in Legambiente’s national campaign, “I Cantieri della Transizione Ecologica,” as an example of technological innovation and sustainable development in Southern Italy.
