Data-centre moratoriums spread from Virginia to Scotland as Congress targets ratepayer costs

Local pauses, a new Brazilian law and a near-unanimous House vote all landed in the same week, aimed at who pays for the power the AI build-out needs.

What happened

The board of Loudoun County in Virginia voted to pause new data-centre applications, introducing a 12-month moratorium in what the industry press calls a data-centre hotspot datacenterdynamics.com. On Wednesday evening the Scottish Parliament passed a pause on new data centres in Scotland, a motion brought by the Scottish Greens; the outlet reporting it noted the measure is watered down against the full moratorium campaigners had sought for months pivot-to-ai.com.

The same pattern is visible elsewhere. Brazil's president signed the ReData data-centre bill into law, after it passed the Senate in September datacenterdynamics.com. In South Africa, local opposition to an American-owned project was summarised by one objection quoted in coverage of the protests: "A massive data center is trying to jump the queue and take our land, water, and energy." restofworld.org

Why it matters to investors

In Washington the fight is over who pays for new generation rather than over whether the buildings go up. The House passed the bipartisan Ratepayer Protection Act by 417 votes to 3, in what Axios called Congress's most significant step yet to shield consumers from the soaring infrastructure costs of the AI boom axios.com. The bill would require state utility regulators to consider rules making data centres cover some of the costs of new power generation, and its passage gives lawmakers a response to an issue that has become a political flashpoint before the midterms axios.com.

A second front targets the tax treatment. Separate legislation has been introduced to stop tax giveaways for data centres, framed against the cost of gas, groceries and housing pappas.house.gov. A companion bill led by McDonald Rivet and Davis would end data-centre tax breaks granted under the One Big Beautiful Bill Act, including 100% bonus depreciation quiverquant.com.

What to watch

Capacity is also running into a labour constraint. Industry research found data-centre expansion is outpacing talent, with more than two-thirds of respondents reporting staffing below operational requirements datacenterdynamics.com.

Three markers follow. The first is whether the Ratepayer Protection Act, which cleared the House by 417 to 3, advances in the Senate, since a near-unanimous vote is unusual for an energy-cost measure axios.com. The second is whether the bonus-depreciation repeal gains support, because it would change project economics rather than siting quiverquant.com. The third is whether local pauses of the Loudoun County type spread to other hotspots, which would move the binding constraint from chips and power to permission datacenterdynamics.compivot-to-ai.com.
