A medical technology manufacturer in County Galway is installing one of Ireland's most sophisticated energy resilience systems, combining multiple renewable technologies to ensure uninterrupted production whilst advancing decarbonisation objectives, the Galway Advertiser reports.

Ohk Energy is delivering an 11.25 MW integrated power installation for Dexcom's Athenry manufacturing facility, blending solar photovoltaic arrays, long-duration battery storage and HVO biofuel generators into a unified system designed to maintain operations under all grid conditions.

The configuration comprises 1.25 MW of rooftop solar across 2,016 panels spanning 178,000 square feet—exceeding Croke Park's footprint—alongside a 6 MW/6 MWh battery energy storage system and 4 MW of HVO-fuelled backup generation capacity. The solar component alone matches power consumption of approximately 340 homes.

The installation targets 30 per cent of Dexcom's daytime annual electricity demand whilst ensuring full operational continuity during grid disruptions. The battery system can participate in EirGrid's DS3 programme during grid events, creating additional revenue streams through stability services.

Brian Healy, commercial managing director at Ohk Energy, characterised the project as demonstrating what Irish industry can achieve. "It shows what's possible – and what's coming next – for Irish industry. It proves that multinational manufacturers can integrate world-class renewable and resilience technologies, support Ireland's grid, hit ESG goals, and enhance the country's position as a hub for sustainable industry," Healy said.

Adrian Furey, vice president of operations at Dexcom, said: "This project represents a major step forward for Dexcom – for our business, for our people, and for the planet."

The system expects 2.5 to 3-year return on investment with full commissioning scheduled for July 2026.
