The move marks a new stage for Entegro. Since 2018, the company has built its reputation designing, building and operating fibre and telecoms networks in Ireland, the UK and the US. With Entegro Energy, it can now take the same end-to-end approach to the energy infrastructure that businesses, public bodies and utilities increasingly depend on. ## About ACEL Energy ACEL Energy was founded in 2022 by Barry Sherry and Declan McDonald, who both join Entegro. The company designs and delivers solar PV, battery energy storage systems (BESS) and demand management for commercial, industrial and public sector clients. Its projects include a 1.2MW ground-mounted solar PV system with Shannon Airport Group, and it has more than 200MW of projects in its pipeline. ## One partner, from generation to grid The deal follows Entegro's acquisition of a majority stake in Nahanagan Electrical Engineering Services in January 2026. Based in Enniscorthy, Nahanagan is a high-voltage specialist that supplies, installs, commissions, operates and maintains HV and MV systems for more than 100 clients, in sectors such as renewables, pharmaceuticals, transport and manufacturing. Entegro Energy brings ACEL's renewable expertise together with Nahanagan's high- and medium-voltage engineering. Together, they cover the full life of an energy project: - **Generation:** design and installation of solar PV - **Storage:** battery energy storage systems - **Grid:** high- and medium-voltage engineering, through to grid connection and energisation - **Operation:** ongoing maintenance and 24/7 fault response for HV sites For clients, this means one partner responsible for the whole project, rather than several contractors working separately. ## 100 new jobs The move supports Entegro's growth as a multi-utility infrastructure business. Entegro plans to create 100 new jobs, growing its team from around 200 to nearly 300 people. John Rooney, Group CEO of Entegro, welcomed the ACEL team and described the deal as “another milestone for Entegro as we continue to build a multi-utility business” across telecoms, power and infrastructure. Barry Sherry, CEO of ACEL Energy, said he and Declan McDonald built ACEL on engineering-led renewable generation and storage, and that “joining Entegro lets us do that at a scale we could not reach alone.” ## About Entegro Entegro is an infrastructure engineering group headquartered in Kilkenny, with operations in Ireland, the UK and the US. Founded in 2018, it designs, builds and operates telecoms and energy infrastructure, and is a delivery partner in the National Broadband Ireland programme. Entegro has been part of Kyntus Group since 2024. ## Related insights ![Shannon Airport solar farm](https://entegro.com/hs-fs/hubfs/News_Shannon-Airport_solar%202.webp?width=400&height=300&name=News_Shannon-Airport_solar%202.webp) News ### Shannon Airport solar farm Shannon Airport Group is generating a large share of its own electricity on site, thanks to a 1.2MW ground-mounted solar PV system ...
