Techno-economic analysis of non-firm grid connections.

Focused grid-risk analysis, scoped to the decision.

Targeted review, project investigation, portfolio comparison, second opinion or transaction support. The right depth for the question, not a generic report.

Operating model

Senior expertise. Tech-enabled throughput. Without the traditional consultancy overhead.

A proprietary engine that reconstructs GB connection queues project by project. Queue reconstruction, build-out probability and reinforcement realisation engineered into the workflow. Senior judgement where it matters.

Early-stage analysis

Pre-application origination of new developments. Where capacity is or will become available, before sites are formally in the queue.

Technical troubleshooting

Get under the skin of constraints, queue concerns and curtailment claims that don't add up.

Retained

Fractional grid-commercial expert

Embedded senior capacity for funds, platforms and developers. Sits in the team. The in-house grid-commercial function without the overhead.

The approach

Four steps.

1

Frame the decision

What needs to be supported. Proceed, pause, renegotiate, prioritise, challenge, originate?

2

Build the evidence base

Public data, queue, curtailment evidence, connection documents, client material. Sources cited, gaps flagged.

3

Test the assumptions

Queue reconstruction with build-out probability for every project ahead. Reinforcement realisation: committed versus planned. Attrition shock testing. Constraint shape, non-firm terms, revenue sensitivity.

4

Translate into action

Findings, sensitivities, mitigants, next steps. In the language used at IC, board, lender or vendor meetings.

Engagement types

Typical shapes of work.

Targeted review

Short, focused work on a specific issue. Often 2 to 5 days of senior time.

Project investigation

Deeper analysis of one site or connection. 1 to 3 weeks.

Portfolio review

Multiple projects, one consistent methodology. Build-out probability and reinforcement testing applied across the pipeline.

Transaction or IC support

Decision-ready analysis for a live process, on a deal timetable.

Second opinion

Independent stress-test of third-party studies, vendor or sponsor claims.

Fractional grid-commercial expert

Retained senior capacity. Embedded in the team without the overhead.

What you receive

Outputs designed to be used.

  • Short note or full report, depending on scope
  • Assumption register. Sources cited, uncertainty stated
  • Queue reconstruction with build-out probability for every project ahead
  • Reinforcement view: committed versus planned, with timing risk attached
  • Constraint and queue findings. Binding constraint identified
  • Sensitivity cases. Energy-, revenue- and BESS dispatch-weighted
  • Configuration sensitivity. Capacity, duration, overbuild, dispatch shape
  • Commercial implications. Valuation, mitigants, monitoring triggers
  • Questions worth pressing on DNO / NESO / seller / sponsor / adviser
  • Verbal walk-through where useful
Useful starting evidence

What to bring to a scoping call.

  • Connection offer or modification
  • Any existing curtailment assessment or third-party study
  • Project capacity, technology, target operating date
  • Target GSP / substation
  • Queue position if known
  • Vendor or sponsor materials, where transaction-related
  • Financial model assumptions, where value sensitivity matters
  • Decision deadline

Not all of this is needed. It just helps a first call land productively.

Pricing

Scoped to the decision.

Time-charge for ad-hoc developer questions. Fixed fees and named-adviser appointments for institutional, lender, IC and transaction work. Clear question, clear deliverable, clear fee.

Senior delivery throughout

You deal directly with the person doing the work.

Transparent assumptions

Traceable methodology, sources cited, no black box.

Confidential

NDA cover where required. Data-room appointments available.

Honest scope

When to use someone else.

Quantail is razor-focused on the techno-economic analysis of non-firm grid connections in GB. Excellent firms cover work outside that scope. We will say so.

Geographic scope

GB-focused. The same published data and methodological approaches apply in other markets. We have experience in mainland Europe and are happy to consider non-GB work on a case-by-case basis.
