Making grid complexity investable.

Quantail translates GB grid constraints, LIFO queue dynamics, and curtailment risk into investment-grade intelligence. Fast, affordable, and built for the people making capital allocation decisions.

What we do

Three pillars of grid investment intelligence.

1

Grid load flow analysis

Published network operator data, combined with proprietary simulation tools, to model how power actually flows across the network. Thermal limits, boundary transfers, and constraint patterns mapped to your specific connection point.

2

Queue and competitor analysis

Full LIFO queue reconstruction showing every project ahead of you, their technology, capacity, development status, and likelihood of proceeding. Attrition scenario modelling shows how your position improves as projects drop out.

3

Financial interpretation

Curtailment risk translated into future cashflows and the metrics that matter for investment committees: revenue sensitivity, NPV impact, DSCR stress testing, and bankable assumption registers. Formatted for IC papers and credit memos.

Stage 1 output

IC-ready screening intelligence in days.

Our Stage 1 screening delivers the key numbers and assumptions your investment committee needs to evaluate curtailment risk. This is not a data dump. It is investment-grade analysis formatted for decision-makers, with transparent methodology, scenario testing, and clear confidence levels.

Queue pos.

Key finding: Headline curtailment at Indian Queens GSP is 20% under firm export rules. However, attrition of projects ahead (particularly St Peter's BESS, which faces delivery risk) reduces effective curtailment to 3-6% by your operational year.

Temporal analysis

When constraints bite matters more than how much.

Curtailment is not evenly distributed across the year. It clusters in winter, peaks during cold snaps, and depends on wind and solar output patterns. Understanding the temporal profile of your curtailment risk is essential for bankable financial modelling.

LIFO queue analysis

Who is ahead of you, and will they still be there?

Energy networks operate on first-in-first-out (LIFO) principles. Curtailment is calculated assuming all projects ahead of you in the queue still exist. But many do not. Projects drop out due to economics, planning delays, supply chain issues, or changing corporate strategy.

Our queue reconstruction models each project's likelihood of proceeding, giving you an attrition-adjusted view of your actual curtailment exposure. It is the difference between a conservative forecast and an investable one.

Where we fit

Not another subscription.

Grid technical consultancies

Traditional grid technical consultancies produce deep grid studies. Thorough, but typically £10k-£30k+ per site and 6-12 weeks. When you are screening 20 sites, that is not feasible. Quantail delivers screening-grade intelligence in days at a fraction of the cost, so you know which sites are worth the full study.

Quantail

Fast, affordable screening intelligence. Stage 1 is £850 fixed fee and 2-day delivery. You get site-specific LIFO analysis and curtailment risk assessment without the full consultant cost. Perfect for pipeline screening.

Economic forecasters

Economic forecasters provide valuable market-level data. But they show regional trends, not site-specific LIFO queue dynamics. They cannot model how attrition in your specific queue changes your curtailment. We take their data further, combining it with queue reconstruction and constraint physics.

Quantail

We integrate market data with site-specific queue analysis. You get regional context plus the local LIFO factors that actually matter for your asset. Economic forecasters show trends. We show your project specific reality.

Corporate Finance Advisors

Information memoranda from corporate finance advisors typically include curtailment estimates. These are often generic, outdated, or based on a single scenario. We independently validate those numbers with site-specific LIFO analysis, temporal profiling, and attrition scenarios. The result often differs materially from the headline.

Quantail

Independent validation of curtailment assumptions. We work backwards from agent claims to check methodology, test scenarios, and flag risks. It is the due diligence that due diligence on agents should include.

In-house teams

Some larger funds build internal grid analysis capability. That takes time, specialist hires, and ongoing data costs. Quantail gives you specialist-grade output without the overhead, ideal for funds that need grid intelligence but are not ready to build a full in-house team.

Quantail

Outsource grid analysis without losing control. Transparent methodology, detailed assumption registers, and direct access to the analyst. Build your in-house capability alongside our work.
