The Minister for Climate, Environment and Energy, Darragh O’Brien TD, today visited BnM’s Cloncreen Battery Energy Storage System (BESS) in County Offaly—one of a growing suite of energy projects that form part of the company’s 5GW pipeline of renewable energy developments.
Co-located with the 75 MW Cloncreen Wind Farm, the BESS is central to BnM’s strategy of delivering large‑scale, flexible renewable infrastructure across its national landbank. By capturing surplus wind energy during periods of high generation and releasing it back to the grid when demand peaks, the system helps stabilise Ireland’s electricity network and supports the integration of increasing volumes of renewable power.
Minister Darragh O’Brien TD said:
“It is encouraging to see BnM delivering real, on‑the‑ground solutions that strengthen our renewable energy system today while building out a substantial pipeline for tomorrow. This Cloncreen BESS is not only improving grid stability in the Midlands—it demonstrates the type of flexible, modern infrastructure we will need as Ireland’s renewable capacity continues to grow.
BnM’s 5GW pipeline of wind, solar and storage projects represent a significant contribution to Ireland’s climate ambitions, regional development and long‑term energy security. Today’s visit shows the positive impact these projects can have—supporting jobs, communities and our national transition to clean energy.”
BnM Chief Executive Tom Donnellan said:
“Cloncreen BESS is an important milestone within our 5GW development pipeline and reflects BnM’s commitment to delivering the flexible infrastructure required for a decarbonised electricity system. As we expand our portfolio of wind, solar and energy storage projects, systems like Cloncreen will ensure that renewable energy is available when it is needed most.
This project shows how our landbank and long‑term investment strategy are enabling Ireland’s transition to a low‑carbon future. We will continue to scale our renewable energy pipeline and deploy innovative technologies that support grid stability, economic growth and energy security.”
