The information memorandum states a high annual capacity. The plant tour shows rows of machines. The seller’s narrative is confident. Independent checks of electricity consumption, despatch history and machine operating logs tell a quieter story—or refuse to line up at all.

technical due diligence for investorsWhen a seller claims high production capacity, nameplate ratings and brochure figures are not proof. Electricity bills, dispatch records and machine logs are among the few operational traces that can corroborate—or contradict—what the plant has actually been producing. As part of , these records can be cross-checked with production data and on-site equipment assessments to evaluate whether claimed capacity is supported by operational evidence.

What Capacity Claims Often Mean—and What They Do Not

Sellers may mean:

Installed or nameplate capacity of equipment
A theoretical maximum on ideal shifts and product mix
A peak month annualised
Capacity after a planned expansion that is not yet running

Buyers and investors need something different: sustained, saleable output the plant has actually achieved under real conditions—and whether that level is available for the business case being bought.

Why Capacity Claims Drift From Reality

1. Nameplate is confused with effective output

Machines have design rates. Changeovers, rejects, maintenance, material shortages and quality holds reduce saleable hours. High installed capacity can coexist with modest shipped volume.

2. Peak months are presented as normal run-rate

One strong quarter is extrapolated to a full year. Seasonality, order book gaps and planned shutdowns disappear from the narrative.

3. Product mix is ignored

Capacity on a simple SKU does not transfer to a complex mix. Claimed tonnes or units may assume a mix the plant has never sustained.

4. Documents are siloed

Production reports, utility bills and despatch data are held in different systems. Without reconciliation, each can be explained in isolation.

5. Idle or underused assets still count in the story

Equipment on the floor is counted as capacity even when utilisation logs show long idle periods.

What Each Evidence Stream Can Prove

Electricity bills

Industrial energy use often correlates with operating hours and load. Bills (or utility statements) over 12–24 months can show:

Whether consumption is consistent with high utilisation or with intermittent running
Seasonal patterns that match—or conflict with—claimed steady output
Step-changes that align with new lines, shutdowns or under-loading

Electricity alone does not equal output. Efficient plants and idle plants both need interpretation. It is a constraint check: very high claimed output with persistently low energy use is a red flag that needs explanation.

Dispatch records

Invoices, e-way bills, despatch registers or ERP shipment history show what left the factory gate:

Actual volumes and values over time
Concentration in few months versus steady flow
Customer and product mix behind the volume

Despatch is closer to “sold and shipped” than to theoretical capacity. It does not capture all finished goods if stock built in the warehouse—but sustained high capacity with weak despatch history still demands a clear inventory and order-book explanation.

Machine logs

SCADA, PLC run-hour logs, production counters, shift reports or OEE records (where reliable) show:

Running hours versus calendar hours
Stops, speed losses and quality losses
Whether bottleneck equipment was actually loaded

Logs vary in quality. Paper shift reports can be optimistic; automated run-hour data is harder to invent consistently. The test is consistency across machines, shifts and months—not a single perfect day.

How to Use the Three Together

Ask for the same period across all three
Align electricity, despatch and production/machine data on the same 12–24 months so patterns can be compared.
Reconcile output to energy and to shipments
High claimed production should leave traces in energy (for energy-intensive processes) and in goods leaving the plant. Large gaps need documented WIP, FG stock or tolling explanations.
Separate nameplate from demonstrated run-rate
Calculate effective monthly or annual output from despatch and verified production records. Compare that to the capacity number in the pitch.
Inspect bottleneck assets on the floor
Walk the constraint process. Match what you see (shifts, crews, queues) to the logs and to the claimed rate.
Test product-mix sensitivity
Confirm whether historical volume was on easy products. Future capacity for your mix may be lower.
Treat missing or inconsistent data as a finding
Refusal to share utility history, despatch detail or machine run data is itself information about transparency and control.
Do not rely on a single proxy
Strong bills with weak despatch, or strong despatch with idle critical machines, each point to different problems—stock building, trading activity, or mis-stated capacity.

Practical Scenarios

Scenario A: High nameplate, flat electricity

Claimed near-full utilisation. Year-long power bills look like single-shift, moderate load. Demonstrated capacity is far below the brochure.

Scenario B: Strong despatch, thin machine hours

Shipments look healthy. Bottleneck machine logs show limited run time. Volume may include traded or outsourced product counted as own capacity.

Scenario C: One peak quarter

Three strong months of despatch and energy use. The remaining nine months are soft. Annual capacity claim is an annualisation of the peak.

Scenario D: Data will not align

Production reports, bills and e-way totals cannot be reconciled without large unexplained adjustments. Confidence in any single capacity number should fall.

Decision Point: Accept the Claim, Rebase It, or Walk Away?

Ask:

What annual output is proven by despatch over a full year?
Do electricity and machine logs support that level of operation?
Is the gap explained by inventory, tolling or product mix—or left unexplained?
Does the investment or supply case still work on demonstrated capacity?

If the case only works on nameplate, the risk sits with the buyer.

Capacity Corroboration Checklist

Capacity definition clarified (nameplate vs demonstrated vs available)
Electricity statements for 12–24 months reviewed
Despatch / invoice / e-way history for the same period reviewed
Machine or line run-hour / production logs sampled
Output, energy and shipments reconciled at a high level
Peak vs sustained run-rate distinguished
Product mix behind historical volume understood
Bottleneck equipment inspected against claimed rates
Gaps documented as findings, not ignored

When This Verification Matters Most

Apply the triad:

before acquiring or financing a plant on capacity-led valuations
before awarding large contract-manufacturing volume on “available capacity”
when expanding orders with a supplier whose plant you have not stress-tested
when the information memo leans on installed capacity rather than shipment history

After the deal or the annual PO is signed, leverage to demand raw operational data drops sharply.

How IMARC Engineering Can Help

IMARC Engineering supports investors and acquirers who need plant capacity claims tested against operational evidence—not only against seller presentations. Technical due diligence can include reconciliation of production, utilities and despatch data with on-site assessment of equipment and bottlenecks.

Relevant support can include independent plant assessment through technical due diligence for investors.

Talk to IMARC Engineering if a seller’s capacity claim is central to your decision and you need electricity, despatch and machine evidence reviewed before you rely on the number: https://www.imarcengineering.com/contact?service=technical-due-diligence-for-investors

Conclusion

Electricity bills, dispatch records and machine logs cannot invent capacity—but they can expose when claimed capacity has not been lived. Used on the same time base and read against bottleneck reality, they turn a marketing figure into a demonstrated run-rate—or show that the figure does not hold.

Buyers who insist on this corroboration price and structure deals on what the plant has actually done. Buyers who accept nameplate at face value discover the shortfall in the first years of ownership or supply.

The practical takeaway is clear: do not ask only what capacity the seller claims. Ask what a full year of power use, shipments and machine operation can support—and treat unexplained gaps as risk, not as detail.
