Price the fear in the connection queue.
£100bn+ of clean energy and data centre infrastructure sits stranded behind grid connection queues. QueueQuant turns queue-delay uncertainty into bankable capital decisions.
Your site, through our engine. Independent, under NDA.
We don't just find the expected case — we price the tail.
GB connection queue — mid-2026
firm connection date
queue over six months
capital gated by the queue
Queue figure derived from the NESO Transmission Entry Capacity register, June 2026: 743 GW contracted to connect, of which 81 GW is built and energised.
A pricing problem, not a mapping problem.
Mapping tools tell you where the grid is constrained. They can't tell you what to do about it. Under TMO4+, Gate 2, and monthly reissued assessments, the queue is a moving target — and deterministic studies price a single future that never arrives. Developers sign non-firm connections blind to curtailment, or over-build firm capacity they'll never use. Either way, capital freezes.
The moving target
Connection assessments are reissued on a rolling basis. Last month's optimal decision is this month's stranded capex.
The curtailment blind spot
A fast non-firm connection can be curtailed 2% of the year — or 35%. Unpriced, that gap is the difference between a strong IRR and insolvency.
The capex paradox
Self-build HV, private wire, and co-located BESS bypass the queue — but demand large, hard-to-reverse capital commitments made under deep uncertainty.
Decision intelligence, not another static report.
QueueQuant integrates machine-learning forecasting across price, curtailment, and queue-timing risks with multi-stage stochastic mixed-integer optimisation under full recourse.
Co-Optimised Capital Sizing
Solves MW capacity, BESS duration, private wire, contestable ICP works, and backup generation together — to structurally minimise stranded capex under queue uncertainty.
Downside Tail Protection (CVaR)
Quantifies the 1-in-20 downside, protecting investment committees from catastrophic delays and unpriced curtailment volatility.
Switching-Boundary Intelligence
Pinpoints the exact inflection points where queue slip or curtailment flips the optimal pathway between Gate 2, non-firm, private wire, and off-grid.
Quantified Decision Alpha (VSS)
Evaluates counterfactuals and regret surfaces to uncover the hidden option value that deterministic studies overlook.
Three stages, from raw uncertainty to a definitive call.
Forecast
Multi-dimensional ML forecasting across price, curtailment, and queue-timing risk generates a probability-weighted scenario tree over the full asset horizon.
Optimise
A multi-stage stochastic MIP solver co-optimises structural decisions today against operational recourse across every scenario — sizing, dispatch, and pathway.
Decide
A capex-versus-risk frontier, tail-risk metrics, and a single recommended pathway — recalculated whenever the network registers change.
Institutional-grade answers for the capital at stake.
We're built for the decision that comes after the search. Once a site is in play, the question stops being “where is there capacity?” and becomes “which pathway, at what risk, sized how?” — a question worth tens of millions more. It's the one we've automated.
Data Centres & Industrial Loads
Compress energisation timelines with hybrid private wire, BESS, and flexible grid sizing — and know what each route costs you before you commit the capital.
Clean Energy IPPs & Storage Developers
Co-optimise BESS power and duration, and price the curtailment exposure in a non-firm offer against the wait for Gate 2 — in numbers, not judgement.
Energy Transition & Infrastructure Funds
Tail-risk (CVaR) underwriting and portfolio valuation your investment committee can interrogate, with every figure traceable to a stated assumption.
years of specialised expertise in stochastic mixed-integer programming, machine-learning forecasting, and energy systems — the foundation QueueQuant is built on. We turn that depth into an enterprise deep-tech SaaS platform: rigorous, repeatable decision-intelligence for the connection queue, delivered as software that re-runs, not a study that ages.
Bring us your hardest connection decision.
Every developer has one: the offer where signing and walking away both look defensible, and nobody in the room can say which is right. Send us that site and we'll show you what each pathway is actually worth — independently, under NDA.
- The switching boundary. The exact curtailment and delay levels at which the optimal pathway flips between Gate 2, non-firm, private wire and off-grid.
- Your one-in-twenty. The CVaR tail on each pathway: what the worst 5% of queue and curtailment outcomes actually cost you, in IRR and in stranded capex.
- Co-optimised sizing. MW, BESS power and duration, private wire and contestable works solved together rather than one after another — the difference between a defensible number and an over-built one.
- The value of not guessing. What you'd have left on the table by planning around one assumed future, quantified.
Every figure traces to a stated assumption, and we tell you plainly which assumptions would change the answer. It's built to go in front of an investment committee, not into a drawer.
£7,500 for your first site — invoiced on delivery. If you go on to license the platform, the full amount comes off your first-year fee.
A study of comparable depth from a specialist consultancy is a £30k–£75k engagement running over two to four months. A consultant prices one future, and the registers move underneath it — so the study can be stale before it lands. Our engine re-solves your site across a thousand futures in minutes, which is why analysis at this price can be refreshed when your queue position changes, and run across a portfolio rather than the two or three sites you can currently afford to study properly.
One 45-minute call, your site capacity and capex envelope, and your connection offer if you have one — or the application you're weighing up if you don't. Most useful when there's a decision with a date on it, so tell us the deadline you're working to.
