Scotland’s parliament has voted to halt approvals for new hyperscale data centres for up to a year, giving the government time to draw up national planning rules for an industry that has expanded faster than the system meant to govern it. The motion passed on September 16 and responds to a rush of proposals for the large computing sites that power artificial intelligence and cloud services.
More than 20 major data centre projects are waiting for decisions across the country, according to parliament. One proposed development in Fife could rank among the largest in the world. Sites of this size can draw tens of megawatts to run and cool thousands of servers, and critics argue that the demands they place on local grids, land and water have outpaced the rules written for a smaller era. The boom in artificial intelligence has added to the pressure, since training and running the latest models calls for ever larger clusters of computing power.
During the pause, which is meant to last no longer than 12 months, ministers will consult on a national framework for how future applications are judged. Under the plan, any facility with a capacity above 50 megawatts would have to complete a mandatory environmental impact assessment before it could proceed. Supporters say clearer and more consistent standards would let residents understand what a project means for their area before construction starts.
Environmental groups welcomed the vote. “There’s much still to be done, but this is a huge step forward,” said Kat Jones of Action to Protect Rural Scotland. Her organization has argued that the planning system was never built for computing sites of this scale, and that communities have had little say over where they are placed or how much power and water they consume once running.
Others urged caution against turning developers away. Daniel Johnson, economy spokesperson for Scottish Labour, said the country needed to weigh the jobs and investment such centres can bring against their effect on the environment, communities and energy supply. The debate mirrors arguments playing out across Europe, including in the Nordic countries that have courted data centres for their cool climates and clean power. Scotland’s government is expected to publish its guidance before the freeze runs out.
