Entegro Group has acquired ACEL Energy, a Monaghan-based renewable energy specialist, for an undisclosed sum, simultaneously establishing Entegro Energy to combine renewable generation, battery storage and high-voltage infrastructure capabilities; the transaction is the second acquisition in Entegro's multi-utility build-out, following the Nahanagan Electrical partnership earlier in 2026.

Entegro Group Holdings Ltd is a Kilkenny-headquartered infrastructure engineering group, majority-owned by Kyntus Group, the French communications infrastructure group that acquired a majority stake in August 2024. Entegro employs approximately 200 people, targeting 300 over the next two to three years, and reported revenue of more than €60 million, targeting €100 million in the coming years. It is a delivery partner in the National Broadband Ireland programme, specialising in the design, build and operation of fibre and telecommunications infrastructure across Ireland, the UK and the US.

ACEL Energy is a Monaghan-based engineering-led renewable energy company specialising in solar PV, battery energy storage systems and demand management, led by CEO Barry Sherry. ACEL's revenue and EBITDA are not publicly disclosed.

The structural driver is the convergence of fibre telecommunications infrastructure and energy infrastructure into a single engineering discipline in Ireland's data centre and grid modernisation buildout. Data centres require both high-capacity fibre connectivity and reliable on-site power and BESS infrastructure; grid operators require both high-voltage engineering and data communications capability for smart network management.

Entegro's existing fibre engineering expertise, combined with Nahanagan's high and medium voltage capability and ACEL's solar PV and BESS expertise, creates an end-to-end multi-utility engineering platform capable of designing, commissioning and operating power and communications systems from a single Irish base.

The Kyntus ownership context is commercially relevant. Kyntus is one of France's leading telecommunications network infrastructure services groups, built through acquisition of specialist engineering businesses; Entegro's multi-utility acquisition strategy mirrors the Kyntus consolidation model applied to the Irish infrastructure market.

For the sector, the Entegro-ACEL deal confirms that Irish engineering services consolidation is accelerating around the convergence of power and communications infrastructure, creating multi-capability contractors capable of serving the data centre, renewable energy and grid modernisation sectors simultaneously.
