Techno-economic analysis of non-firm grid connections.

Public network data, used carefully.

Public network and queue data. Disclosed methodology. Sponsor materials where provided. Assumptions traceable. Limitations stated. Decision support under uncertainty, not a black-box answer.

Data sources

What goes in.

Connection queues

Embedded Capacity Registers, Reform Outcomes datasets, queue position registers.

Network data

LTDS, CIM-format network models, sensitivity factors, pre-event limits, branch loadings.

Constraint & curtailment

Published curtailment evidence, reinforcement plans, ANM scheme parameters, T/D boundary technical limits.

Generation profiles

Empirical, technology-specific half-hourly profiles published by network operators.

Client materials

Connection offers, third-party studies, financial assumptions, transaction context shared under NDA.

Public market data

Public price and dispatch references for revenue sensitivity. Not proprietary forecasts.

From data to decision

Four steps.

Input

Evidence base

Connection offer, queue, network data, constraint info, client materials.

Analysis

Constraint & queue

Reconstruction, binding-constraint identification, temporal shape, attrition, configuration sensitivity.

Translation

Commercial framing

Revenue sensitivity, valuation, downside, configuration trade-offs, assumption register.

Decision

Action

Proceed / pause / reprioritise / renegotiate / challenge / monitor.

Geographic scope

GB-focused. Principles travel where the evidence base supports it.

Quantail’s home market is GB. Non-GB work is considered case-by-case, depending on the availability of network data, queue information, curtailment rules and regulatory context. The underlying data formats Quantail relies on (the IEC’s CIM family of standards) are international, so where local network operators publish CIM-compatible data the same approach can in principle apply, the practical question is whether the local evidence base is rich enough to support a credible view.

Honest scope

What Quantail does and does not do.

Does: Independent grid-risk interpretation, scenario testing, second-opinion review, decision-ready translation, portfolio comparison, transaction support, configuration sensitivity. Public network data, traceable methodology, senior judgement.

Does not: Replace formal G99 / G100 connection compliance studies. Replace DNO- or NESO-stamped filings. Provide volumetric merchant revenue forecasting. Provide regulatory or legal advice. Imply private network operator data where none is held.
