Key takeaways
- Label targets and realised activity as different measures.
- Compare compatible products, units and reporting periods.
- Do not infer live availability from unused theoretical capacity.
- Use policy developments to guide questions, not manufacture current quotations.
A policy objective is a future-oriented statement
Shanghai's published 2024 fuel-transition plan sets development objectives for its green-fuel supply system. Shanghai fuel-transition plan
The plan's existence does not establish that every objective has been achieved. A monitor should retain the publication's policy status and seek separate evidence before describing actual commissioned facilities or completed sales.
For a current transaction, the capacity-and-activity review is not provided; obtain current verified information. Record each observation's measure, product, unit, period, development status and limitations, with current availability left to an actual supplier confirmation.
Distinguish the stages behind a capacity claim
A policy target describes an intended outcome. A project announcement describes a proposed or developing asset. Commissioned capacity describes an established capability on a stated basis. Actual sales describe recorded activity over a period.
Do not move an observation from one category to another because its announcement is old or the project appears prominent. The monitor needs evidence of the relevant stage.
Where the capacity definition is unclear, preserve that limit. Nameplate, permitted, contracted and practically available capacity may refer to different propositions; use the source's actual term rather than assuming equivalence.
Keep the product and unit attached
Different fuel series may be published in different units or describe different product categories. Do not add or compare them without an appropriate supported basis.
A volume measure and a mass measure do not become interchangeable because both concern marine fuel. Any analytical conversion needs the relevant qualified inputs and a clear explanation of its purpose.
The same caution applies to a broad alternative-fuel category. Capacity associated with one product does not establish supply of another product meeting the buyer's accepted specification.
ILLUSTRATIVE: utilisation does not reveal an available parcel
ILLUSTRATIVE fictional figures, not Shanghai statistics or policy targets. Assume a clearly defined facility has annual capacity of 1,000,000 tonnes and recorded annual sales of 600,000 tonnes on the same product and measurement basis.
The simple annual sales-to-capacity ratio is 60%, leaving an arithmetic difference of 400,000 tonnes between the two annual figures. That difference is not evidence that 400,000 tonnes are currently in stock or available to a particular buyer.
The figures do not identify timing, existing commitments, suitable product inventory or a feasible delivery appointment. The ratio can describe the defined historical comparison without answering those separate transaction questions.
Interpret utilisation only within its stated boundary
A ratio can be useful if its numerator and denominator concern the same product, geography, time basis and capacity definition. If those conditions do not hold, the result can look meaningful while comparing incompatible quantities.
Even a valid annual ratio can conceal concentration in particular periods. Do not infer the availability of a short service window from an annual total.
The monitor should explain what the calculation establishes and what it leaves open. It should not fill those gaps with assumed operating schedules, inventory levels or supplier commitments.
A capacity-monitoring decision table
| Published item | Correct status | Evidence needed for a stronger conclusion |
|---|---|---|
| Policy objective | Intended future development | Verified implementation outcome |
| Project announcement | Proposed or developing capability | Actual commissioning and scope |
| Reported capacity | Defined capability on the published basis | Compatible activity data for utilisation analysis |
| Recorded sales | Activity over a specified period | Current stock and commitment evidence for availability |
| Unused arithmetic difference | Difference between defined annual figures | Actual transaction-specific supply confirmation |
| Supplier quotation | Bounded current commercial proposition | Acceptance and remaining service conditions |
Fictional case: a target becomes a procurement assumption
A fictional buyer reads a Shanghai fuel-development plan and treats its future capacity objective as evidence that the desired product will be readily available for an upcoming call. The buying schedule therefore postpones the actual supplier enquiry.
A reviewer separates the policy objective from current supply evidence. The desk obtains a proposition for the real quantity, specification and service window instead of using the target as a substitute.
The development plan remains relevant to longer-term market research. It simply does not provide the missing current commitment. This distinction prevents a strategic observation from being mistaken for an operational purchase basis.
Keep the weekly note focused on verified change
Report whether new evidence changes the status of a project, the definition of a capacity figure or the observed activity series. Do not repeat a target as new market supply each time it appears in another announcement.
For the immediate buying decision, maintain separate current offer and availability information. If no public source establishes it, record that limitation and use authorised transaction confirmations.
A useful monitor connects evidence to a specific next question. It does not need to predict future prices or assume that planned infrastructure will remove every service constraint.
Common mistakes
Avoid treating policy objectives as completed capacity, adding incompatible fuel units and describing the difference between capacity and sales as available stock. Other errors include inferring a delivery window from an annual ratio or delaying a necessary enquiry because a development announcement sounds reassuring.

Frequently asked questions
Does planned capacity prove current supply?
No. Establish the actual development stage and obtain a current supplier proposition.
Can a utilisation ratio be useful?
Yes, when its product, unit, period and capacity basis are compatible and its limits are explicit.
Is unused annual capacity the same as available inventory?
No. It does not identify current stock, commitments or delivery feasibility.
What belongs in the monitoring slot?
Record measure, product, unit, period, development status, evidence and the limits of the interpretation.
