Singapore picked four proposals from twenty on 21 August, giving Digital Realty, Equinix, Keppel Data Centres and ST Telemedia Global Data Centres 50 MW each.

Key takeaway

Singapore's four winners hold provisional 50 MW allocations, with Digital Realty's tied to more than 50% green power.

Four proposals were selected from twenty by Singapore's Economic Development Board and the Infocomm Media Development Authority on 21 August, under the country's second Data Centre Call for Application⁠1. Digital Realty, Equinix, Keppel Data Centres and ST Telemedia Global Data Centres each hold a provisional allocation of 50 MW, 200 MW in total, and the agencies will decide within 18 to 24 months whether to run a third call.

Singapore hands out data-centre capacity through competitive calls rather than granting it to whoever applies, which is why twenty proposals were chasing a fixed pool. A provisional allocation is a right to build up to a stated load, not a commissioned hall, and none of the 200 MW is running.

Digital Realty then published detail the joint announcement omitted. Its 50 MW sits at Jurong Island's low-carbon data centre park, conditioned on sourcing more than 50% of that capacity through green power pathways and on meeting the authority's efficiency standard under the call. No commissioning date was given⁠2.

Bidders were therefore pricing a green-power obligation into their proposals before a single building went up. Elsewhere the same arguments about power sourcing and efficiency arrive after consent is granted, when a project is already sunk and a regulator is negotiating with a built asset. Taiwan put a generation obligation on its largest electricity users in early August, a condition of the same kind imposed on operators already drawing power. Singapore has put them at the front, where the cost of the condition lands on the bid rather than on a retrofit.

Deep Analysis

In plain English

Singapore does not have much space or spare electricity, so instead of letting anyone build a data centre who wants to, the government runs a competition for a fixed amount of new capacity. This time, four companies won a share each, and one of them, Digital Realty, only gets to keep its allocation if more than half the power it uses comes from green sources.

Deep Analysis
Root Causes

Singapore has limited land and a power grid that cannot absorb unconstrained data-centre growth, so it rations new capacity through periodic calls rather than approving every credible application.

Conditioning Digital Realty's allocation on sourcing more than half its power from green sources reflects the same constraint from the emissions side: the city-state is using scarce new capacity as leverage to shape the fuel mix of what does get built, rather than regulating existing sites after the fact.

Seven projects, one linked to Google, asked SEA this month for rulings that they fall outside full environmental review; four declared diesel-storage volumes just under the review-triggering tonnage, mirroring the mechanism Alto Jahuel used in July. The clustering suggests the threshold is being engineered, not sized to need.

Ireland's planning appeals body refused the €1.5bn Killala data centre on 17 September, overturning Mayo County Council's 2025 grant for lack of a fixed grid-connection agreement and no corporate renewable power-purchase agreement. The ruling makes matched-power evidence, not planning consent alone, the deciding factor.

The two groups' 6 August appeal, filed through the Legal Resources Centre, kept Cape Town's approval of Equinix's data centre suspended through this window over missing water, emissions, noise and diesel-generator data. Deputy Mayor Eddie Andrews confirmed on 20-21 September that the suspension holds.

Aragon's economy chief Eva Valle said on 11 September that Spain's draft decree, requiring 80% hourly-matched renewables via a 10-year power-purchase agreement, is unmeetable by any project and threatens Blackstone, Azora and Microsoft builds already under way. Aragon holds 3,600 MW of granted grid access against 108 MW built.

Abbott ordered TCEQ on 21 September to halt every pending data-centre permit until projects pay their own way and complete ERCOT and Texas Water Development Board audits. Texas built the country's most permissive data-centre market; freezing it signals even that market has hit its grid limit.
