Public-lens observation / GB / system-level

Grid Continuity Status Card

What the public grid lenses can say as of 30 June 2026.

Observation date: 30 June 2026Published: 1 July 2026Method: Public Physical Ledger v0.1Author: Pingxin Wang
Public-lens observation status: cross-checks settling. Public lenses were available and observed frequency was near 50 Hz. Some asset-level cross-checks still awaited settled metering. This is not a grid-stability assessment.
Frequency / 30-day public trace49.999 Hz

0.22% outside +/-0.2 Hz; 0.000% outside the statutory band in the observed record.

BM support diversity / 1-HHI167

Effective distinct units bearing accepted BM balancing actions. Descriptive, not network redundancy.

Observed role separation

Storage appeared frequently, but carried a smaller share of instructed energy

Within the observed Balancing Mechanism records, storage represented 35.8% of accepted actions and 3.2% of instructed energy. The observation is a high-frequency, lower-volume public BM role. It is not evidence of asset fatigue, service quality, total revenue, or internal cycling.

Top accepted-action classes: battery storage 35.8%; secondary BMU 24.1%; unidentified 13.4%. The supply body and the balancing-action body are not the same aggregation.

Lens maturity

Nine public lenses clear; data QA remained under review

LensStatusWhat it records
Frequency / BOALF / FUELHHClearObserved system frequency, accepted BM actions, and fuel mix records.
DCP capability / EAC / absence auditClearDeclared capability, contracted-service scope, and public-lens absence checks.
B1610 / REMIT / PNClearLagged metered trace, public outage disclosure, and declared physical intention.
Data QAWarningCross-source timing, identity, revision, and maturity checks were not uniformly settled.
Claim boundary

What this observation cannot establish

Not observed internally

Asset health, degradation, fatigue, thermal state, warranty condition, maintenance need, or cause of any public trace.

Not a decision output

Failure prediction, grid-stability verdict, service-delivery assessment, underwriting, credit, investment, dispatch, or control advice.
