Data Centres in Scotland: Operating Sites, Pipeline and Planning Rules

What is operating and what is only proposed?

The gap between the two is the story. Fifteen operating facilities, the biggest of them 12 MW, sit beside proposals measured in hundreds of megawatts. The proposals are applications, not capacity: several have no published size, some have already fallen away, and none can be counted as supply until they are consented, connected and built.

Proposal (reported)	Area	Size (MW)
Blackdog	Near Aberdeen	600
Auchtertool	Fife	600
Two Ravenscraig schemes	North Lanarkshire	1,050 combined
Two Chapelhall schemes	North Lanarkshire	1,000 combined
Hurlford	East Ayrshire	540

The planning rules changed in September 2026

• National Planning Framework 4 (NPF4) designates green data centres as national developments, which streamlines consent in principle (Harper Macleod, March 2026). The framework does not define "green data centre" in detail.
• Environmental impact assessment: a Direction from the Scottish Government's Chief Planner, dated 16 September 2026 and in force from 17 September 2026, requires an EIA for new data centres with a power capacity above 50 MW. Smaller schemes are still screened case by case (Scottish Government).
• Hyperscale pause: in mid-September 2026 the Scottish Parliament voted for new hyperscale data centre approvals to pause while national planning guidance is developed. Reporting says ministers are expected to report on guidance by the end of 2026 and publish it within 12 months; the exact reach of the pause has not been confirmed (Computing, Euronews). Check the current position before relying on it.

The Lanarkshire AI Growth Zone

The UK Government designated North Lanarkshire as Scotland's first AI Growth Zone in January 2026; coverage of the zone says it could unlock up to 500 MW of data centre capacity (DCD). DataVita's proposed DV4 campus at Chapelhall is part of it and has been submitted to North Lanarkshire Council. The September 2026 EIA Direction applies to any new data centre above 50 MW.

Where Scotland's data centres sit on the grid

The distribution networks are SSEN Distribution in the north of Scotland and SP Energy Networks in the central belt, with transmission owned by SP Transmission and SSEN Transmission. Scotland is rich in renewable generation: Harper Macleod reports that Scotland generated the equivalent of 113% of its own electricity consumption from renewables in 2022. The constraint is moving that power to where proposed campuses are, which is why grid capacity, not generation, is the delay in most proposals.

What Scotland means for on-site solar

Rooftop yield is lower in Scotland than in southern England. Using PVGIS 5.2 (EU Joint Research Centre) for a flat roof tilted 10 degrees facing south with 14% losses, modelled output is 816 kWh per kWp in Edinburgh, 775 in Glasgow and 788 in Lanarkshire (Motherwell), against 928 at Slough. That is 12% to 17% less energy per panel. Because a data centre's load is flat and continuous, nearly all of it is still self-consumed and avoids imported power, so the case turns on roof area, structure and import price rather than export income.

Panels on an existing building are a different route from the new-build hyperscale schemes above: it is not a new data centre application, but structure, fire safety and grid-connection requirements still apply. Sizes, costs and the G99 process are the same as elsewhere in Great Britain; see data centre solar costs, G99 for data centres and the city pages for Edinburgh and Glasgow.
