How balancing work is organised in the public GB record

Supply role

Transmission-level FUELHH supply shares. These categories describe recorded supply, not balancing participation.

Gas

28.5%

Wind

24.0%

Nuclear

15.5%

Interconnect

17.9%

Balancing role

Two views of the same registered high-confidence storage lens in the public BM record.

Accepted-action count

36.4%

Instructed-trajectory energy

3.3%

Same population identity; different denominators and units. Side by side, not subtractable. The storage lens is not an estimate of every GB battery asset.

Distribution across participants

Accepted actions were distributed across the observed BM-unit population as follows.

Effective units (1/HHI)

153

Units with accepted actions

504

The effective count is 1/HHI over accepted-action shares. It does not establish ownership diversity, operational resilience or physical redundancy.

Public visibility boundary

Dispatch causality, condition, reliability, credit or future outcome.

Trace and lawful extension

Every displayed value is copied verbatim from a claim listed by the dated handoff. LFR retains a claim-level trace for every value, including its population identity, numerator, denominator, observable role and unsupported readings. The method summary is available via the contact below; the Field Report expands the same daily handoff.

This card renders, verbatim, claim values computed by frozen, versioned procedures from public records of the GB balancing mechanism and independently re-audited each night, at whole-system level with zero named units. Headings are framing; numbers are observations. Freshness is declared per channel. It expresses no assurance and no opinion. It is not asset condition assessment, not dispatch causality, not underwriting or credit advice, and it offers no view of any future outcome. Whether these procedures are sufficient for any purpose is solely the reader's determination.
