As hyperscalers scale outward, secondary cities now court projects by guaranteeing land, natural-gas access, and fast-track permits.

AI/ML Workloads: Redefining Power Density Requirements

Generative AI servers in Ireland draw three to four times the power of legacy CPU racks, accelerating a shift to liquid cooling and busbar-based distribution. The International Energy Agency warns that global data center demand could touch 945 TWh by 2030, with AI workloads representing one-fifth of that total^{.[1]International Energy Agency / Ifri, “AI, Data Centers and Energy Demand,” ifri.org} Irish operators now specify rack densities above 70 kW, driving adoption of smart PDUs that report circuit-level draw in real time. Liquid-to-chip cooling loops are being paired with heat-recovery skids that supply district networks, exemplified by the Tallaght scheme that taps AWS waste heat to warm municipal buildings.

CRU On-Site Generation Mandate: Catalyzing Microgrid Development

Since 2025, new Irish data centers must match imported power with on-site generation or storage, effectively turning each campus into a micro-utility. Developers now integrate gas turbines, solar arrays, and battery energy storage systems (BESS) into the base design to satisfy the rule. Eaton and Siemens Energy’s modular 500 MW plant concept illustrates how packaged gas-plus-hydrogen solutions can be dropped into constrained grids and later converted to zero-carbon fuels.^{[2]Eaton Corporation, “Eaton, Siemens Energy Join Forces to Provide Power and Technology,” stocktitan.net} Financing structures reward plants that trade surplus generation into the wholesale market, giving operators a hedge against volatile tariffs. The mandate also spurs collaboration with utilities to align dispatch schedules with national renewable peaks, minimizing curtailment.

Grid-Interactive UPS: Turning Loads into Grid Assets

Microsoft proved that a modern UPS fleet can deliver frequency-response capacity without jeopardizing uptime, unlocking new income via the DS3 ancillary-services program. A single 50 MW campus can dedicate up to 20% of its power budget to system-stabilization calls, a critical lever as data centers now represent 21% of Ireland’s electricity load and could hit 30% by 2030.^{[3]Commission for Regulation of Utilities, “Large Energy Users Connection Policy Proposed Decision Paper,” cru.ie} Vendors such as ABB and Vertiv embed grid-support logic into new UPS frames, synchronizing discharge windows with EirGrid’s dispatch signals. Participation allows operators to offset higher energy costs tied to AI racks while bolstering national grid resilience.

Dublin Grid Moratorium: Reshaping Development Patterns

EirGrid’s freeze on new megawatt-scale connections in Dublin through 2028 affects the 82 facilities that already dominate national capacity. Operators lacking signed agreements are diverting budgets to counties Wicklow and Westmeath, where land banks can be coupled with private gas feeds. Echelon’s EUR 3.5 billion Wicklow campus showcases this pivot, combining wind PPAs and embedded generation to bypass urban bottlenecks. The moratorium also accelerates interest in subsea connectivity projects that anchor outside the capital, such as Amazon’s Cork landing station linking Ireland to the US.

Pending Diesel-Genset Phase-Out: Accelerating Backup Innovation

Ireland’s forthcoming rules that curb diesel standby units are pushing operators toward gas-fired sets, hydrogen-ready turbines, and battery energy storage. Lithium-ion prices now justify installing BESS blocks sized to ride through typical outage windows, complemented by renewable firming during off-peak hours. Some operators trial hydrotreated vegetable oil (HVO) in existing diesel fleets to cut emissions ahead of formal deadlines. Schneider Electric’s microgrid controller orchestrates these hybrids, ensuring seamless failover while reporting real-time emissions to meet compulsory annual disclosures.

Segment Analysis

By Component: Shift Toward Intelligent Power Platforms

UPS systems generated 32% of 2024 revenue, anchoring the Ireland data center power market as operators prize proven ride-through capability. The newest frames add lithium-ion batteries and grid-interactive controls, turning traditional backup into dispatchable capacity that earns ancillary-service fees. Vendors such as Eaton bundle predictive analytics that flag battery degradation early, cutting maintenance spend and averting unplanned outages. Intelligent bypass features also let technicians isolate modules without dropping load, a key factor for Tier IV contracts driving zero-downtime service-level agreements.

PDUs represent the fastest-growing slice, expanding at 17.35% CAGR as sensors and branch-circuit monitoring become compulsory in AI halls. Granular insight into sub-rack consumption supports dynamic load placement, helping to shave peaks that would otherwise trigger expensive grid-capacity charges.

By Data Center Type: Colocation Dominance Meets Hyperscale Momentum

Colocation vendors held 35.2% of 2024 revenue, capturing enterprises that prefer opex-friendly footprints over greenfield builds. Established grid contracts give these incumbents bargaining power in a constrained market, allowing them to resell capacity to newer entrants that lack permits in Dublin. Inter-connection density within carrier-neutral halls also attracts content providers that need low-latency hand-offs, making colocation a durable pillar of the Ireland data center power market.

Hyperscale operators, however, post the steepest growth at 20.1% CAGR to 2030 as generative AI drives server refresh cycles. Cloud giants increasingly co-locate dedicated power substations on campus to meet CRU’s one-to-one import rules, effectively securing control over their energy destiny. Many pairs of on-site turbines with wind PPAs to meet corporate carbon targets while navigating curtailment risks. This self-sufficiency model is reshaping supplier negotiations, with hyperscalers insisting on modular power skids that arrive pre-wired to compress deployment timelines.
