Coverage & definitions

Transmission-metered domestic generation excludes embedded estimates, pumped storage and imports. Other may include batteries. Renewable share includes wind, natural hydro and biomass, not nuclear; biomass is not zero-emission.

Demand and carbon use separate intervals. Five-minute snapshots are not half-hour averages. Methods and source definitions

WHAT CHANGED / EVIDENCE FIRST

What changed?

Explore network constraints ↗

Comparable completed half-hours are unavailable. Missing readings are not converted into trends.

Forecast network context

No time-valid day-ahead boundary periods are available in the cached source. This is a separate forecast window, not measured congestion or an explanation of the earlier generation changes.

Unused capacity, a forecast exceedance, or a schedule/output difference is not a curtailment estimate.

Deterministic comparisons of official evidence. No generated causal claims. Source revisions are available in the network evidence view. Contains BMRS data © Elexon Limited copyright and database right 2026. Supported by National Energy SO Open Data.

Carbon outlook

Lowest-carbon 2-hour window

Loading the carbon forecast…

Forecast, not a guarantee. Lower carbon does not necessarily mean a lower bill.

Forecast evidence

Carbon Intensity API · retrieved time unavailable. Upstream issue time not supplied.

Only contiguous future periods covering the selected duration qualify. Rank by duration-weighted average; ties choose the earliest start. No historical lows or actual values substitute for missing forecasts.

Half-hour forecasts, gCO₂/kWh
All charts & controls

Historical measured generation has different embedded-source coverage from the live mix. Gaps and incomplete periods are not observations.

THE GRID BRIEF / 2026-09-29

A dated report.
A different perspective.

Generation, changing renewables and gas, with the limits of the evidence in view.

THE EXPLAINER / CLEANER ELECTRICITY

When is electricity
actually cleaner?

Why the answer changes with the weather—and why clean and cheap are not the same thing.

Every number has a source. Inspect this snapshot.

Scope: Great Britain, excluding Northern Ireland. Demand is initial national demand outturn (INDO), with the source’s transmission-system boundary. Biomass is included in renewable share; storage is excluded. Individual inputs can cover different intervals.

Definitions and limitations · Source directory · How to cite

Carbon and enrichment readings unavailable. Generation and demand have separate source status above.
