How do you calculate chain-of-identity equipment energy cost?

Multiply COI connected load in kW by operating hours by your electricity rate. For 1.2 kW over 220 hours at $0.16/kWh, that is 264 kWh costing $42.24.

What is the COI equipment cost per transaction?

Divide total energy cost by transactions supported. At $42.24 across 120 patient batches, energy is about $0.35 per COI transaction — negligible per unit but committed across every lot.

What equipment makes up the COI connected load?

Barcode and 2D scanners, thermal label printers, RFID readers, identity kiosks and the local servers or edge devices running the COI software. Sum their draw for the connected load input.

Why does COI energy cost matter if it's so small?

The dollar value is minor, but the calculation sizes the load that must sit on backup power. A COI outage mid-release can freeze manufacturing, so the kWh figure feeds UPS and generator design more than cost of goods.

How do I lower COI cost per transaction?

Increase transactions through the same hardware rather than chasing efficiency — at a fixed 264 kWh, more patient batches drive the per-transaction cost down. Power management on idle kiosks and printers helps marginally.

Is nameplate load the same as actual COI draw?

No. Scanners and printers spend most time idle, so measured average draw is often 30-60% of the summed nameplate. Use metered data where you have it for a realistic energy figure.

Chain-of-Identity Equipment Workload Calculator

Chain-of-identity (COI) verification is the unbroken digital and physical link tying a patient's apheresis, drug product and infusion together — and it runs on barcode scanners, label printers, RFID readers, kiosks and the servers behind them. This calculator turns the connected load, runtime and facility electricity rate of that COI equipment into a total energy cost and a cost per patient transaction. Manufacturing IT, facilities and CGT operations teams use it to allocate utility overhead to per-patient cost of goods and to right-size backup power, because a COI system that drops mid-transaction can halt a release. The energy per transaction is small, but COI hardware runs near-continuously across every patient lot a facility touches.

What this calculator does

Estimate operating cost for chain-of-identity scanners, labelers, workstations, and verification equipment during production.
a cell therapy operations team is estimating the equipment burden of chain-of-identity verification across patient batches
It computes total COI equipment energy cost as connected load times operating time times rate, plus kWh used and energy cost per patient transaction.

Formula used

COI equipment operating cost = verification equipment connected load × operating time × electricity rate
COI equipment cost per transaction = operating cost ÷ patient batches or COI transactions supported

Inputs explained

COI verification equipment connected load:
COI equipment operating time:
Blended facility electricity rate:
Patient batches or COI transactions supported:

How to use the result

Use it when allocating IT and utility overhead to per-patient cost of goods or sizing UPS coverage for COI-critical equipment.
It assumes a constant connected load, but scanners, printers and kiosks idle most of the time, so average draw is well below the nameplate sum.

Current U.S. benchmarks

As of Apr 2026, industrial electricity averages 8.7 cents per kWh across the U.S. (EIA), up 5.5% from a year earlier. State averages range widely, so plants should confirm against their own tariff.
U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
