Scotland requires impact assessments for data centers above 50MW
The 16 September planning direction is the second move on large data centers from Scottish ministers in a month, after councils were told to report every such application
- Edinburgh sites named in August: Wester Hermiston (EIA direction) and Redheughs Avenue (appeal recalled)
- Council notification window, from August: seven days after validation
- Scientific input: the Scottish Science Advisory Council
- Instrument: the Town and Country Planning (Environmental Impact Assessment) (Data Centres exceeding 50MW Power Capacity) (Scotland) Direction 2026
Businesses counting on new large-scale data center capacity in Scotland should expect it to arrive later than early announcements suggested, as a mandatory assessment is likely to add time to every big application. Before signing for Scottish-hosted or sovereign cloud services on a site not yet built, customers should ask about its planning status and whether the contract allows exit if delivery slips. Operators already running capacity in Scotland look likely to gain pricing power in the meantime.
“Ensuring that an Environmental Impact Assessment is always part of the application process will create a level playing field for developers and will ensure potentially significant environmental effects are considered from the outset.”Hannah Mary Goodlad, public finance minister, Scottish Government
The Scottish Government published a planning direction on 16 September that requires an environmental impact assessment (EIA) for every new data center with power capacity above 50MW. Developers must submit the assessment during planning, rather than wait for a case-by-case decision on whether one is needed.
It follows a direction issued on 17 August by public finance minister Hannah Mary Goodlad, which made planning authorities notify Scottish ministers of new data center applications above 50MW. The government said that step would help it monitor the pipeline of applications and the implications for wider infrastructure. At the same time, Goodlad recalled a planning appeal on a proposed data center in Edinburgh so that ministers take the final decision, and required EIAs at sites in Fife and Edinburgh.
Applications below the threshold still fall under existing EIA regulations, where the need for an assessment is decided case by case. The government describes data centers as a sector attracting a broad range of views and concerns, and says the evidence on their environmental impact is still developing.
