Lumcloon Energy and Hanwha Energy open Ireland's first hybridised grid-stabilisation system

The official opening of the Shannonbridge B project on 2026-03-06 introduces Ireland's inaugural hybridised grid-stabilisation system, a critical development for the nation's energy infrastructure. This facility uniquely integrates a 4000MVA synchronous condenser with a 180MWh battery energy storage system, offering a sophisticated solution beyond conventional battery storage. The commercial logic centers on providing essential grid services, such as inertia and fault current, which are traditionally supplied by fossil fuel generators but are increasingly scarce with higher renewable penetration in Ireland. This dual-technology approach by Lumcloon Energy and Hanwha Energy directly addresses the complex stability challenges faced by EirGrid, ensuring reliable power delivery across the Irish network. The project's hybrid design is engineered to maintain system strength and frequency control, crucial for supporting Ireland's transition to a decarbonized electricity system. This combination allows the system to contribute both instantaneous power and longer-duration stability, a key differentiator for the Irish grid. Hanwha Energy, a South Korea-based subsidiary of Hanwha Group, leverages its specialized expertise in energy storage systems (ESS) for this Irish venture, expanding its European footprint in advanced grid solutions. Lumcloon Energy, an Irish renewable energy developer, delivers this project as a significant addition to its portfolio, which already encompasses over 1 GW of utility-scale battery storage, solar PV, and onshore wind projects across Ireland. This collaboration allows Lumcloon Energy to solidify its position as a leading developer of innovative energy infrastructure within its home market. For Hanwha Energy, the Shannonbridge B project demonstrates its capability to deploy complex hybrid systems, moving beyond solely solar power plants and standalone ESS. The successful operation of this 180MWh BESS and synchronous condenser system in Ireland provides both counterparts with a tangible track record in pioneering grid stability technology.
