Norwegian energy company Statkraft has completed and energised a hybrid renewable energy project in County Offaly, Ireland, combining a 55.8 megawatt (MW) wind farm with a 20MW battery energy storage system.
The Cushaling site is the first in Ireland to integrate wind generation and grid-scale battery storage at this scale, according to Statkraft. The battery system has a four-hour duration capability, allowing electricity to be stored during periods of low demand and discharged during peak consumption to support grid stability.
Statkraft said the wind farm includes turbines with tip heights of up to 185 metres, making them the tallest currently in operation in the country.
“This project represents a significant step forward for hybrid renewable energy in Ireland,” the company said in a statement. “The battery system enables renewable electricity to be stored and deployed when it is most needed, supporting grid resilience and enhancing energy security.”
The company added that the development was delivered through close coordination between internal teams focused on development, community engagement, construction and grid integration.
Statkraft said the Cushaling project highlights the growing role of hybrid renewable systems in reducing fossil fuel dependency and accelerating the energy transition.
