Grid Continuity Status Card
What the public grid lenses can say today
GB · 2026-07-11
public · system-level
Public frequency trace near 50Hz · asset-level checks settling
Most public lenses current and frequency near 50Hz in the public trace; some single-asset cross-checks still await settled metering.
vs previous card (2026-07-10): 3 of 6 headline figures moved at the precision shown. Consecutive cards share ~29 of 30 window days — near-identical days are expected on a calm grid; every figure is recomputed and independently hashed each day.
This window: 283,081 accepted balancing actions across 530 active units, 30 days.

The shock-absorber, not the energy-carrier
In the balancing mechanism, storage takes
35.4% of accepted actions but only
3.2% of instructed energy — high frequency, low volume.
A boring baseline (permutation null) would put storage at 10.0% [6.4–14.0%] of actions — the observed share sits far outside it (distance from boring, not a verdict).
Top BM bearing classes: battery_storage 35.4% · secondary_bmu 24.0% · unidentified 13.7% · supply body ≠ balancing body.
Who supplies is not who balances
| class |
share of supply (FUELHH) |
share of BM balancing |
| wind | 25.6% | 8.0% |
| gas | 36.4% | 6.4% |
| nuclear | 13.0% | 0.0% |
| interconnector imports | 13.7% | 0.0% |
| battery storage | — | 35.4% |
| supplier / demand-side layer | — | 24.0% |
Different measures (national MW output vs count of accepted
balancing actions) — not subtractable. "—" = no FUELHH category, not zero generation. FUELHH is transmission-level
(no solar / embedded generation). Co-occurrence, not causality.

Lens degraded: data QA WARN
Data QA note: 33 active units have no capacity denominator (excluded from normalisation); 16 units with <2 acceptances (gap geometry undefined). Headline action counts remain recompute-gated (claim_audit PASS).

Every figure above reproduces from public raw data + frozen code
(independent reproduction harness). No named assets. No operator identification. Naming an asset needs
authorisation — that is a separate, private evidence pack.
Public grid data already contains an external duty mirror.
Most reports show revenue.
This shows the public physical role behind it.
