Summary
- The Dublin deployment includes a 10MW / 20MWh BESS, a power plant controller, and SCADA system.
- Pure DC’s campus is designed around a microgrid with three energy centres, battery storage, and future grid integration.
- The project turns Ireland’s grid constraint into a facility design issue, with storage, controls, and on-site power built into the campus.
Ingeteam has supplied a 10MW / 20MWh battery energy storage system for Pure DC’s Dublin data centre campus, adding grid-forming storage to a microgrid designed for hyperscale operations in a constrained Irish power market.
The system includes Ingeteam’s power plant controller and SCADA equipment, and forms part of Pure DC’s Orion Phase 1 development. The company says the battery has been commissioned and integrated with the site’s power stations and energy management system.
The permanent campus arrangement will combine three energy centres with on-site battery storage, taking total installed capacity to 110MW. Ingeteam says the microgrid can operate independently from the national grid while retaining flexibility to connect when grid capacity becomes available.
Power architecture shaped by constraint
Ireland’s data centre market has spent years under pressure from connection limits, demand forecasts, and political concern about large electricity loads. Pure DC’s Dublin project pushes part of that pressure inside the fence line, where batteries, controls, inverters, temporary energy centres, and permanent plant become part of the delivery model.
A microgrid does not remove the electricity requirement. It changes how the facility manages supply, stability, and future connection. Battery storage can smooth load fluctuations, support power quality, provide reserve, and help bridge the move from temporary power arrangements to a more permanent grid-connected model.
Grid-forming capability gives the storage system a more active role than conventional backup. Ingeteam says the installation uses liquid-cooled INGECON SUN STORAGE C Series inverters to create a 10MVA grid-forming system without power derating. That type of architecture becomes more valuable as AI and cloud loads create sharper demand profiles and greater sensitivity to voltage and frequency stability.
Microgrids move into data centre delivery
Data centres in Ireland have often been discussed through the national grid queue. The Dublin deployment shows a more complex campus model, where on-site energy infrastructure is designed alongside the data halls rather than treated as a temporary workaround.
That approach brings its own planning and operational burden. Energy centres can create emissions, fuel, noise, maintenance, and safety questions. Battery systems require fire strategy, monitoring, spacing, controls, and emergency planning. The campus must operate as both a critical digital facility and an energy asset.
Power electronics suppliers are being pulled deeper into data centre development as a result. UPS, switchgear, and generation remain central, but grid-forming batteries, SCADA, plant controllers, and energy management systems are becoming part of the same critical-power conversation. AI loads are accelerating that shift because connection timing and power stability now drive commercial delivery.
The Dublin campus gives Ireland a live example of how hyperscale capacity can be staged when grid access is delayed or limited. If the model performs reliably, similar architectures may appear in other constrained European markets where developers cannot wait for traditional connection timelines but still need a path back to the grid.
