A public interest investigation — Michael Knox — June 2026
Twenty hyperscale data centres are being waved through Scottish planning. Their combined electricity demand exceeds Scotland’s entire winter peak consumption. The UK Government wants to subsidise their bills. Scottish households will pay — and nobody in government is telling them.
Part One — The Scale of the Problem
Scotland is not dealing with a distant projection. The applications are lodged. The developers are identified. The sites are named. What is absent is any policy framework that ensures Scotland captures a meaningful share of the value these facilities will extract — from Scottish land, renewable energy, freshwater and grid infrastructure.
No government body has published a cumulative impact assessment of this pipeline on Scotland’s grid, energy prices, or household bills. The planning system is processing each application in isolation as if the other sixteen do not exist.

Part Two — What the Planning System Is Not Asking
Every Scottish household faces hidden bill increases of £145–225 per year to fund transmission upgrades, capacity market contracts, and balancing services these facilities require. These costs flow through TNUoS and DUoS charges, socialised across all consumers. No planning application addresses this. No planning authority has been directed to consider it.

A large hyperscale site may draw up to 19 million litres per day in peak summer conditions. No planning authority currently requires a standardised water abstraction assessment. The proposed Auchtertool site in Fife sits on the River Ore catchment. The cumulative summer impact of 15 large facilities drawing simultaneously has never been modelled by any public body.
A ministerial direction to SEPA — not new legislation — could require assessment today
The UK Health Security Agency recommends a 60-metre buffer between homes, schools and hospitals and new overhead high-voltage transmission lines. Each hyperscale facility requires a grid connection equivalent to a small power station, often in rural and semi-rural areas with no existing such infrastructure. No cumulative EMF impact assessment has been published for this pipeline as a whole.

In November 2025, DSIT announced data centres in Scotland would be eligible for reductions of up to £24 per MWh on electricity costs. The stated justification: absorbing surplus renewable energy that cannot flow south due to transmission bottlenecks.
The justification collapses under examination. Hyperscale data centres do not operate flexibly. They draw at full load 24 hours a day, 365 days a year. When the wind stops blowing — as it frequently does in winter — these facilities compete directly with households for expensive dispatchable generation.
| Metric | Current position | Under the Compact |
|---|---|---|
| Household bills | Rise £145–225/yr | Reduced via levy credit |
| Grid costs | Socialised to consumers | Developer-funded |
| Water impact | Unassessed | Capped & published |
| EMF risk | Unassessed | 60m buffers enforced |
| Electricity subsidy | £24/MWh to developers | Withdrawn |
| Permanent jobs | Claimed 3,400; actual ~150–300 | Contractual targets |
Part Three — The Employment Evidence
The Lanarkshire AI Growth Zone announcement on 29 January 2026 carried a specific promise: more than 3,400 jobs. Prime Minister Starmer said it would create “good, well-paid jobs.” Technology Secretary Liz Kendall said the benefits would “be felt locally.”
A Freedom of Information request by Action to Protect Rural Scotland revealed how the figure was constructed. The 3,400 estimate was scaled from the Cambois data centre in Northumberland — estimated at 1,200 construction jobs and 400 operational roles — with employment multipliers of 1.5–1.6 applied.
The problem: 61% of the final figure comes from multiplying up for wider economy roles. And the construction jobs are temporary — 12 to 18 months — counted as if they were permanent local employment. The Cambois source data itself had already been challenged: Labour MP Ian Lavery told the House of Commons the real operational figure was 150, not thousands.
Scottish households are being asked to accept higher electricity bills so that facilities employing fewer permanent staff than a village secondary school can train AI models for clients in California.

Part Four — The Alternative
Built entirely within devolved planning powers. No new primary legislation required. An updated NPF4 and the political will to set the terms of consent — before the first concrete is poured and the argument is lost.
Every facility above 200MW must demonstrate firm, dispatchable power supply for 100% of its maximum demand, independent of the public grid, before consent is granted. The developer must also contract renewable generation plus grid-scale battery storage at 150% of average annual energy demand. Any gas peaking capacity requires a binding phase-out date and carbon capture obligation.
£15 per MWh consumed, ring-fenced in a Community Energy Fund administered by the relevant local authority, applied as direct per-unit credits to all residential electricity accounts in the distribution network area. For a 500MW facility consuming 3,500 GWh per year: £52.5 million per year directly reducing household bills.
Standardised EIA covering maximum daily abstraction, cooling methodology, source water assessment, and catchment impact. Closed-loop or air-side cooling required as standard. Evaporative cooling permitted only where the EIA demonstrates no material impact. SEPA abstraction licence pre-assessment mandatory. Water source must be specified before consent is determined.
Independent cumulative impact assessment of all associated grid infrastructure. Minimum 60-metre exclusion zone from residential properties, schools and hospitals for all new high-voltage transmission lines and substations, consistent with UK Health Security Agency guidance. Full public consultation before consent is determined.
Part Five — Act This Session
Pause all data centre consents above 200MW IT load for twelve months, pending a government-commissioned cumulative impact assessment covering energy, water, grid infrastructure, and consumer bill impact. Ireland, the Netherlands and Singapore have all enacted similar pauses. This is prudent governance, not obstruction.
The Scottish Government should formally and publicly oppose the UK Government’s £24/MWh electricity discount and refuse to facilitate the scheme in Scotland.
The National Planning Framework 4’s designation of all “green” data centres as national developments was designed for a different era. It must be amended to require Compact compliance as baseline for national development status.
SEPA and planning authorities must be directed to require standardised water abstraction and cooling methodology assessments for any application above 50MW, with all results published. A ministerial direction — not legislation — is all that is required.
Commission and publish, within six months, an independent assessment of the cumulative network cost impact of the current planning pipeline on Scottish household electricity bills. The public deserves to know what is being built in their name and at their expense.

SUBJECT: Scottish Data Centre Planning — Four Conditions Holyrood Can Apply Now
Dear [MSP Name],
I am writing as a constituent from [your town/area] with urgent concerns about the environmental impact of hyperscale data centre development in Scotland. Twenty facilities are currently progressing through the planning system, yet not a single cumulative environmental impact assessment has been carried out. Consents are being granted individually, in isolation, with no assessment of their combined effect on Scotland’s water supply, electricity grid, or the health of local communities.
The water risk is immediate. A 500MW facility using evaporative cooling draws up to 19 million litres per day from the water supply system — equivalent to the daily consumption of a city the size of Perth. In Fife, where several sites are proposed, Lomond Hills reservoirs stood at 21% capacity in 2025, the lowest level in 30 years, and the River Eden catchment has had abstraction licences suspended twice due to water scarcity. No developer has been required to declare their cooling system or their true water demand before consent is granted.
The electricity supply position is equally unassessed. The combined demand of the current pipeline exceeds Scotland’s entire winter peak consumption, yet no assessment of grid capacity, infrastructure cost, or household bill impact has been published. Each facility requires grid connection infrastructure on the scale of a small power station — 56-metre steel lattice towers carrying 275kV or 400kV overhead lines, and substations of up to 6 hectares. Published field measurements show that electromagnetic fields from 400kV infrastructure exceed the threshold associated with childhood leukaemia risk in the IARC classification out to 60–80 metres from the conductor at typical operating loads. No cumulative EMF assessment has been required as a condition of any Scottish data centre consent.
The Scottish Energy Compact proposes four planning conditions that address each of these failures directly. Crucially, all four operate within devolved planning powers — they require no Westminster legislation, no reserved-powers override, and no new Act of the Scottish Parliament. They are planning conditions, attachable to consent by ministerial direction under existing powers today:
Condition 1 — Firm Power: The developer must demonstrate a contracted pathway to 100% dispatchable power supply at full cost-reflective grid charges before consent is granted. No grid reinforcement costs may be passed to consumers.
Condition 2 — Community Energy Fund: A mandatory Section 75 planning obligation requiring £15 per MWh consumed to be paid into a ring-fenced local energy fund for bill relief and insulation — entirely within devolved powers, consistent with established wind farm community benefit practice.
Condition 3 — Water and Cooling: Evaporative cooling is prohibited for facilities above 200MW. The developer must declare their cooling system and obtain SEPA Environmental Authorisation for water abstraction before — not after — planning consent is granted.
Condition 4 — EMF Buffer Zone: A mandatory 100-metre planning setback from any new high-voltage transmission conductor or substation to the nearest home, school, or hospital, grounded in published field decay data showing EMF levels approach background at that distance.
I would ask you to raise these conditions in the Scottish Parliament and to press the Cabinet Secretary for Net Zero and Energy to issue a ministerial direction applying them to all applications above 50MW. No primary legislation is required. The full analysis is at scottishenergycompact.co.uk.
