Tarsk pauses new data-centre grid connections in Brennmark for 18 months
STEP 01
Start here
The grid authority says the Brennmark North substation is near its limit as data centres reach 31% of local demand. Industry and a union-funded think tank disagree sharply on how many jobs are at stake.
In one paragraph
The Tarsk Grid Authority will accept no new data-centre connection applications in the Brennmark zone for 18 months from 1 December; 14 pending applications totalling 2.3 gigawatts are suspended.1 Data centres used 31% of the zone's electricity in the year to September, up from 12% in 2021, and the energy minister says the main substation is near its limit at peak times.23 An industry body says about 5,900 jobs are at risk; a union-funded think tank puts permanent jobs at about 600.56 Some operators are talking to Lunevian officials about moving projects near Vessen.7

How we got here
Background, from the study guide
2021
12% of demand

2023
Four applications
The Brennmark connection queue holds four data-centre applications.
2026
31% and 14 applications
Data centres reach 31% of zone demand; 14 applications totalling 2.3 gigawatts are waiting.
1 December 2026
Pause begins
An 18-month pause on new data-centre connection applications in Brennmark takes effect.
2028
New capacity due
The earliest date the energy minister gives for new capacity at Brennmark North.

The Grid Authority announces an 18-month pause on new data-centre connections.1
Energy minister backs the pause, citing limits at Brennmark North.3
Industry body says about 5,900 jobs are at risk.5
Northgate Policy Institute estimates about 600 permanent jobs.6
Operators reported to be in talks about sites near Vessen.7
An anonymous channel claims one large project will be let through.11
The Authority says no exemptions have been granted.13
STEP 06
Agreed and disputed
Of 7 key facts: 2 official statement, 5 reported.
How many jobs the pause puts at risk
- Tarsk Digital Infrastructure Association (industry body): About 4,800 construction jobs and 1,100 permanent jobs across the 14 suspended projects.5
- Northgate Policy Institute (think tank; part-funded by trade unions): About 600 permanent jobs, roughly 40 per site, based on operators' planning filings; construction jobs are temporary.6
Whether a pause is the right response
- The Lantern Review (commentary): The constraint was foreseeable, and freezing investment penalises companies for slow grid building.10
- Civic Ledger (commentary): With data-centre demand rising from 12% to 31% in five years, pausing is a grid operator doing the arithmetic in public.12
- Harbour Quarterly (analysis): The pause buys time, but without a published ranking method the queue may simply re-form when it ends.14
STEP 07
Open questions
- How many jobs are at stake. The industry figure of about 5,900 and the think tank's estimate of about 600 permanent jobs count different things, and neither has been independently checked.56
- How the Authority will rank applications when the pause ends. It has not published a method.114
- A claim that a 600-megawatt Halden Compute project will be let through comes from a single anonymous channel with no documents. It is uncorroborated, and the Authority says no exemptions have been granted.1113
- Whether Lunevia could take the projects. Its officials say its own grid is tight and its connection rules are under review.78
