DTGen, the standby power specialist within DCC Energy, has acquired Irish generator maintenance firm Realpower, a deal that matters to energy services providers and large power users because it combines generator installation with maintenance in sectors where backup power underpins business continuity.

DTGen is a Glasgow-headquartered standby power specialist within DCC Energy, with 22 years of experience, sites in Glasgow, Bristol and Northampton, and more than 50 data centre projects delivered worldwide.

Realpower is a County Westmeath generator maintenance specialist based in Moydrum with 16 years of experience in planned preventative maintenance, inspections, servicing and emergency repair of critical power infrastructure.

DCC Energy Ireland is the Irish arm of Dublin-headquartered DCC Energy, offering fuels, power and solar capabilities and announcing the acquisition.

The combined business has more than 110 employees, including 70 engineers, and expects to create at least 10 new jobs. Farrell Spollen has been appointed managing director for Ireland, and Realpower’s customers will continue to receive their existing service. The combined business will offer turnkey solutions from system design and installation through commissioning, maintenance, remote monitoring and lifecycle support.

Nigel Newton, managing director at DTGen, said: “Realpower has established itself as one of Ireland’s most respected maintenance providers, with service capabilities that complement DTGen’s generator project delivery expertise, making it an excellent addition to the DCC Energy Ireland and DTGen group.” Michael Tumulty, owner of Realpower, said: “Joining forces with DTGen, and being backed by DCC Energy Ireland, is a positive step for Realpower.”

Data centres used 23% of Ireland’s metered electricity in 2025, up from 5% in 2015.

Under Irish policy, new data centres must provide dispatchable onsite or nearby generation or storage matching their maximum import capacity and source at least 80% of annual demand from additional Irish renewables.

Maintenance is the operating link: servicing and load-bank testing can help identify faults before a generator is needed during a power outage, including at hospitals and data centres.

For the sector, a group that installs and maintains backup systems under one roof gives large power users a single contact for design, servicing and emergency support across the UK and Ireland.
