Grid Inefficiencies

Tracking clean-energy pressure, exports and storage load using existing Live Grid Data feeds.

Pressure index 37 /100

Higher means the grid is showing stronger clean-energy delivery pressure.

Clean export estimate 0.00 GW

Exports weighted by current clean generation share.

Pumped storage load 0.00 GW

Power being absorbed by pumped storage.

Clean pressure 3.92 GW

Estimated clean-pressure signal above a cautious 55% clean-share baseline.

Methodology note: this page combines your modelled grid-pressure signal with reported Elexon system-price and NESO constraint-breakdown layers where available. It is still not a direct wind-curtailment monitor, so modelled and reported figures are labelled separately.

What this page is showing

When clean output is high and demand is low, the grid may need to export power, absorb it into storage, reduce output, or rebalance elsewhere. This page starts with the parts your site can already calculate safely.

How the calculations work

Plain-English methodology for visitors.

Clean export estimateexports × clean share

Shows how much exported power is likely to be clean, based on the current clean generation mix.

Storage absorptionpumped-storage load × clean share

Shows how much storage loading is likely absorbing clean electricity at that moment.

Clean-energy pressuremax(0, clean share - 55%) × GB demand

A cautious pressure signal that starts only when clean generation share is high.

Pressure indexclean share + exports + storage + low demand + pressure

A 0–100 score. It helps compare periods but does not claim confirmed curtailment.

Why this matters

Useful context without overstating the data.

Not all pressure is waste

High renewable pressure can mean exports, storage charging, transmission congestion, balancing actions or market-driven reductions.

Modelled vs reported

Pressure and curtailment-risk signals are modelled. Price and constraint cards are labelled as reported only when a source is readable.

Curtailment comes next

Confirmed curtailment should be introduced only when balancing actions can be classified and explained transparently.

Grid inefficiencies are the moments when available electricity cannot be used in the most efficient way because of demand, storage, transmission, market or balancing limits.

Why start with this version?

The safest first version is not to estimate direct wind curtailment until the proper constraint and balancing feeds are wired in. Instead, this page highlights visible pressure signals already present in your live data.

How to read the numbers

Clean export estimate means exports weighted by clean generation share. Storage absorption means pumped-storage load weighted by clean generation share. Clean pressure means clean output above estimated GB demand. These are useful signals, not settlement-grade waste figures.

What this update adds

This version adds the operational timeline, live event stream and curtailment-risk layer, while keeping modelled signals separate from reported price and NESO constraint data.

What can be added next?

The next stage is direct wind-curtailment classification from balancing actions. Until then, constraint cost and constraint volume remain reported system-level indicators, not direct wind-waste claims.
