Generator diesel at Ochrefield Tower (synthetic)
Held out of filing: Open material finding on this figure.
Why this tier
Measured (V2): the figure is built on your own meter, the tank probe.
It stays at V2 while the fuel records and the probe are further apart than their combined uncertainty explains. Records that disagree are never averaged.
How to move this up
Decide the open finding: was the 5,600 L difference stock left in the tank, or fuel that did not arrive?
Who to check it with
Bulk fuel supplier (synthetic): ask for the nine delivery notes and whether the litres were corrected for temperature.
What could we add
Ask O. Haddad (synthetic) for tank level readings at the start and end of the quarter, and either side of 14 to 27 May. Opening stock and closing stock: Not known, because the level readings are not held. This whole difference may be stock.
Chain of evidence
The tier describes only the quantity. The factor has its own band, carried into the figure’s band.
Quantity
- Tank probe TP-07: 36,400 L, GSD 1.04
- Gap 14 to 27 May stated, not filled
- Tested against fuel records: z 2.91 against 2.58, PROPOSED
Factor
- EF.DIESEL.STAT.2026: 2.68 kgCO2e per L (2.47 to 2.90, P5 to P95), GSD 1.05
- Geography GLOBAL: a combustion constant bound at this parameter’s own level, not a fallback

Set aside
- Run-hours: Hours are not litres, so they explain use but are never added to the quantity.
- Instrument slot: held
- Practitioner slot: empty. No assurance engagement is recorded for this period.

What should we add next?
Pick something you could add and whose it would be. The answer is the engine’s.
Nothing is picked yet.
What is missing to clear V3
- Held: an instrument reading, Tank probe, version 2
- Not held: a second party who independently agrees, A fuel delivery docket signed at the tank
The cheapest second party: Bulk fuel supplier (synthetic), who already produce a docket. With both, this figure could clear V3.
Band over time
Not known, because this figure has only one computed band this period.
