11 serial developers have connected
every project they've ever started.
1,116 sponsors have never connected a single one.

Both groups are competing for the same grid capacity. Manathric maps which projects, sponsors and substations will determine where AI infrastructure actually lands — before the market knows.

661 GW In queue. 67 GW expected to deliver.
17 AI datacenter projects mapped (8,000 MW)
11 GSPs under AI demand stress

Constraint Intelligence — UK, 2026

Physical constraints the queue data reveals before they appear in financial analysis.

Critical
0 MW
Energy storage in the NESO queue near Cambridge GSP — while Microsoft and ARM bring 1,250 MW of AI demand by 2028.
Queue entry deadline: September 2026 · 3 months from now
Critical
80.6%
Withdrawal rate in May 2026. 104 of 129 project movements were withdrawals — 35 sigma above the 3-month baseline of 1.6%.
Source: NESO transition events, Q2 2026
Signal
£11.8bn
Provisional development capital committed behind sponsors with zero delivery history. Recovery probability: below 10%.
589 GW × £20k/MW central estimate · Low: £8.8bn · High: £14.7bn
Confirmed
92.7%
Survival rate for sponsors with 3+ previously connected projects — versus ~45% for first-time developers. Confirmed at p < 0.0001 on 82 observations.

UK queue — larger than PJM (320 GW) despite being 1/10th the territory. The UK constraint is the global prototype.

Why 79% of UK Energy Storage Projects Never Reach Connection
1,516 active energy storage projects. 86 ever connected. Our model estimates fewer than 150 will ever connect. The rest — 417 GW of capacity — are phantom projects keeping real capital in suspension. This note maps the exact failure modes: GSP congestion, project size, and sponsor quality.

GRID ANALYSIS · QUEUE INTELLIGENCE · UK
The UK Grid Queue Is Much Smaller Than Investors Think
Of 661 GW in the UK grid queue, our model estimates only 67 GW has a realistic chance of ever connecting. The rest exists on paper. Telis Energy holds 17.1 GW in queue — more than total installed UK battery capacity — and has connected zero megawatts.

SPONSOR INTELLIGENCE · TRACK RECORD · UK
Why Sponsor Quality Matters More Than Technology
89 companies have ever connected a significant energy project to the UK grid. 1,367 are trying. 11 serial developers — SSE, ScottishPower, Uniper, RWE — have connected every project they've ever started, at 100% completion rate. £11.8bn in provisional capital sits behind sponsors with zero delivery history.

Independent Infrastructure Research

Manathric builds data systems that track physical infrastructure at a granularity that public reporting does not reach. We cross-reference the NESO TEC Register, REPD planning data, Companies House ownership records, AI datacenter expansion pipelines and transmission upgrade plans.

The goal is not a dashboard. The goal is to reduce structural uncertainty for professionals who make real infrastructure decisions — before that uncertainty becomes consensus.

No access fees. No data sales. No advertising. Research notes are published when findings are solid enough to be useful.

Data before narrative
Every claim is sourced, quantified and methodologically documented. Assumptions are stated explicitly.
Physical over financial
Grid congestion, queue depth ratios and substation capacity constraints are the upstream signal. Price follows.
UK as wedge, not ceiling
The UK grid queue is the sharpest prototype for global AI infrastructure constraints. Europe and the US follow the same pattern at 5–30× scale.
Corrections welcome
Contradictions, field observations and data corrections improve the model. We track methodological versions.
Are we missing something?

Contradictions, corrections and field observations are welcome. If you work in battery development, grid consultancy, infrastructure finance or energy data — and you are trying to answer questions about what is actually buildable — we are probably researching the same things you need.
