Key takeaway

NERC's data-centre reliability standards cleared a first ballot but still need a final vote and FERC filing.

The North American Electric Reliability Corporation, or NERC (which writes the binding reliability standards for the continent's grid), saw its first computational load (CLO) standards pass their initial industry ballot on 18 September⁠¹. The ballots on CLO-001, CLO-002 and CLO-003, alongside two revised facility-connection standards, opened on 9 September, and all five passed.

The CLO standards would apply to sites with at least 50 MW of load connected at 100 kV or above. The Federal Energy Regulatory Commission, or FERC (the federal grid regulator), left NERC to draw that line in a July order⁠². Above it, a data centre would carry reliability duties rather than connect as an ordinary customer.

An initial ballot does not approve a standard. A final ballot follows in November and board adoption in December, ahead of a 31 December filing deadline at FERC. Five grid operators already hold abeyance at FERC on their own large-load answers until November.

Deep Analysis

In plain English

NERC, the body that writes electric-grid reliability rules for the United States and Canada, has three new standards, CLO-001, 002 and 003, that just passed their first industry vote. They would apply to data centres of at least 50 megawatts connected at high-voltage points of 100 kV or more. This is an early step, not a final rule. The standards still need further approval before they take effect, but they are the first NERC rules written specifically to manage computing load rather than power generation.

Deep Analysis

Root Causes

NERC standards only bind utilities and grid operators once they clear a multi-stage ballot and gain approval from federal regulators, a process that can take years.

Passing the initial industry ballot is an early step, not adoption, but it is the first continent-wide reliability standard written specifically for computational load rather than for generation or transmission equipment.

NERC large-load rules pass first ballot

If adopted, the standards would give large data centres reliability duties on the North American grid instead of treating them as ordinary customers.

Different Perspectives

Chilean data-centre developers

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.

An Coimisiun Pleanala

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.

Housing Assembly and Foxglove

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.

Brazil (President Lula, signing Redata)

Lula signed Lei 15.504 on 15 September, creating the Redata tax programme and keeping the Senate's water cap with no veto, while Aneel authorised Scala's AI City to join the national grid from January 2028. Brazil is recruiting capacity other markets are now turning away.

Aragon regional government (Eva Valle)

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.

Texas Governor Greg Abbott

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.
