AI Data Centre Rules by Region: Singapore, China, Ireland and the Two Levers Every Regime Uses

An earlier briefing mapped the data centre rules taking shape across Germany, the wider EU, Australia and the United States. That was three continents; it was not the whole map. Through 2026 the same shift, from treating data centres as an energy-sector niche to treating them as regulated infrastructure, has reached Asia-Pacific and Ireland, and the regimes there are worth reading in their own right. This piece covers Singapore, China and Ireland, and starts with the shared logic that makes all of these rules easier to parse.

The basics: two levers

Almost every data centre rule in force pulls one of two levers, and increasingly both.

The first lever is energy efficiency. The standard measure is Power Usage Effectiveness, or PUE: the ratio of the total energy a facility draws to the energy that actually reaches the computing equipment. A PUE of 1.0 is the theoretical ideal (every watt reaches the servers); a PUE of 1.5 means half as much again is spent on cooling, power conversion and overhead. Regulators pull this lever with binding PUE caps, requirements to reuse waste heat, and mandatory energy reporting.

The second lever is grid impact. A large AI data centre can draw as much power as a small city, so regulators increasingly control who may connect, whether a site must bring its own generation or renewable supply, and who pays for the network reinforcement. This is where the sharpest recent decisions sit, because it is where data centres and ordinary electricity consumers compete for the same grid.

Read through that lens, the regional regimes below stop looking like a patchwork and start looking like variations on the same two questions: how efficient must you be, and what must you bring to the grid.

Singapore: ration, do not ban

Singapore is land and power constrained, and for several years capped new data centre capacity outright. It has since replaced the freeze with a managed, sustainability-gated allocation. On 30 May 2024 the Infocomm Media Development Authority published its Green Data Centre Roadmap, which aims for all data centres in Singapore to reach a PUE at or below 1.3 at 100 percent IT load over roughly the next decade, close to best-in-class operation.

The roadmap is not a single statute but a package: the BCA-IMDA Green Mark for Data Centres was refreshed on facility-level efficiency by end-2024, with standards for IT equipment efficiency and liquid cooling following. Critically, Singapore released at least 300 MW of additional capacity that operators must compete for, and future capacity allocations require applicants to show viable low-carbon energy plans and best-in-class PUE. In other words, growth is available, but it is rationed to the operators that can prove efficiency and clean supply.

China: national targets, and moving the compute west

China regulates efficiency through national targets rather than a single connection rule. Official policy targets a PUE of 1.25 for large data centres by 2025, sitting within a broader national plan to bring the average data centre PUE below 1.5, and it applies Dual Control targets covering both total energy use and energy intensity, alongside rising renewable-uptake requirements (see the government summary, China sets green targets for data centres, and this Carbon Brief explainer).

The distinctive Chinese lever is spatial. The 2022 East Data West Computing initiative steers new data centre build toward western provinces, where large solar and wind resources sit, while keeping latency-sensitive workloads in the east. For an operator, meeting the PUE and renewable conditions is effectively part of securing project approval, and where a facility is allowed to be built is itself a policy instrument.

Ireland: reopened, with conditions

Ireland is the clearest case of the grid lever. From 2021 the Commission for Regulation of Utilities operated an effective moratorium on new data centre grid connections around Dublin, after EirGrid warned that concentrated load was pushing the system toward its physical limits. In its decision on a new electricity connection policy for data centres, the CRU has now reopened the door, but on strict terms.

Under the new Large Energy Users connection policy, which applies to connection applications submitted after 12 December 2025, a new data centre must meet at least 80 percent of its annual electricity demand with additional renewable generation projects located in the Republic of Ireland, on a six-year glide path for those projects to be built and start generating. It must also hold dispatchable generation or storage, at or near the site, that matches its import capacity, so that it can support rather than strain the grid at peak. Applications already in progress before that date continue under the previous framework.

What it means for AI governance teams

The common thread is that the physical location of AI compute now carries a distinct, and growing, compliance profile. An organisation training or serving models at scale should treat data centre regulation the way it already treats data protection: as something to check per jurisdiction, not assume. Three practical steps follow.

• Put infrastructure on the risk register. Energy efficiency, grid connection terms and water use are now board-reportable dependencies for AI, not just operational detail, exactly as our three-continent briefing argued for Germany, the EU, Australia and the US.
• Ask the location question in vendor due diligence. Where a cloud or colocation provider physically hosts your workloads determines which of these regimes applies, so the region of the data centre belongs in third-party assessments and contracts.
• Track the thresholds, not just the direction. Singapore's PUE target, China's approval conditions and Ireland's renewable and generation requirements all move; confirm the current instrument before relying on a number.

For how this connects to the wider control environment, see our AI GRC guide; for the model-facing side of the same regimes, the EU AI Act explainer and the EU AI Act timeline set out the obligations that attach to the systems running inside these buildings.

General information, not legal advice. Statuses were current at 21 July 2026; Singapore's allocations, China's five-year targets and Ireland's connection policy are all being implemented and refined, so verify the instrument before relying on a threshold.
