Reading diesel yard tugs beside the electricity story
Fuel dockets and tug idle habits belong in the same resource consumption pack as electricity — with different evidence rules.
Electricity tables dominate many assessment packs. Yard diesel often decides whether a logistics site’s resource story is complete. Two tugs idling through a loading peak can outweigh a careful lighting retrofit in cost and fumes — yet the evidence looks different.
Evidence we accept
- Fuel dockets or tank gauge logs with dates
- Supervisor notes on which shifts run which tugs
- Direct observation of idle behaviour during a peak window
We do not convert “busy week” anecdotes into litre totals.
How it appears in the pack
Diesel sits in its own section with litres (or dollars) by period, then a short observation note on idle and staging. Cross-links to electricity appear only when charging of electric yard gear is also in scope — otherwise we keep the resource types separate to avoid muddy comparisons.
Practical tip
If dockets are incomplete, say so early. A portfolio pulse review can still flag the site as diesel-heavy relative to peers using cost shares; a flagship assessment should not invent missing litres.
