Sectors — Food & Agro-processing
The cold chain is the product. Everything else is negotiable.
A processing plant is a temperature obligation with machinery attached. Refrigeration runs whether or not the line does, and the moment it falters the loss is not a kilowatt-hour — it is stock. Metering the chain stage by stage shows you what it costs to hold and gives you warning before it slips.

- Cold storageNever stops
- DispatchRuns on loading
Chilling and cold storage cannot be moved at all. Knowing what each of them costs to hold, and which of the rest can be shifted, is where every other decision in a processing plant starts.
Metered stage by stage, from the gate to the truck
Each stage carries a different load, a different risk, and a different reason to be measured on its own.
Intake and reception
What draws power
Reception chillers, plate coolers, wash-down water heating, weighbridge and offloading.
What is at stake
Raw material arrives warm and on somebody else’s schedule. If chilling capacity is not there at the moment of arrival, the clock on the product has already started.
Watch: Demand spike at intake against the hour deliveries actually land
Chilling and holding
What draws power
Compressors, condensers, glycol and chilled-water circuits, bulk tanks.
What is at stake
This is the load that must never stop. It also runs continuously, which makes it the single largest line on most processing bills and the easiest one to stop noticing.
Watch: Compressor run-hours, cycling frequency, and creeping current draw
Processing
What draws power
Pasteurisers, homogenisers, dryers, mills, boilers, CIP cleaning cycles.
What is at stake
The heaviest and most schedulable load in the plant. It is also the one most often run at whatever hour the shift has always run it, rather than the hour it costs least.
Watch: Energy per batch, and how much of each run lands in the peak tariff band
Cold storage
What draws power
Cold rooms, blast freezers, door heaters, evaporator fans, defrost cycles.
What is at stake
Finished stock sits here with the full value of everything upstream already in it. A refrigeration failure over a weekend is not an energy problem; it is a write-off.
Watch: Overnight and weekend baseline, and any upward drift in it
Dispatch
What draws power
Loading bay refrigeration, dock doors, vehicle pre-cooling, standby and backup supply.
What is at stake
The last point where the chain can break, and the one most exposed to doors held open and supply interruptions during loading.
Watch: Bay refrigeration draw during loading windows, and standby changeover events
Refrigeration tells you it is failing long before it fails
A compressor working harder to hold the same temperature draws more current, cycles more often and runs for longer. None of that is visible on a monthly bill, and none of it is visible to a person walking past a cold room that still feels cold. It is plainly visible in a load profile.
So the same meters that tell you what refrigeration costs also tell you when something in it has changed — while there is still time to schedule a service rather than absorb a loss.
- Rising baselineOvernight consumption creeping up week on week with no change in stock or ambient conditions.
- Shortening cyclesA compressor restarting more frequently to hold the same setpoint — often the first sign of a refrigerant or seal problem.
- Weekend anomaliesConsumption on days with no production, when the only thing running should be the cold chain itself.
- Supply eventsVoltage dips, phase loss and interruptions logged with a timestamp — the record you need when a batch is questioned.
The first three are found by comparing the plant against itself. The fourth is the one a processor is most often asked for by somebody else.

Once the chain is measured, capital stops being a guess
Jesa was about to buy a solar system sized against estimated consumption. Nineteen meters across the New and Old Plant transformers and the major loads established what the plant actually draws, and when. The proposed system was larger than the site needed.
The same data set showed raw milk was being processed at hours that cost more than they had to. Both findings came out of one deployment, because both questions turn on the same measurement.

Cut from the solar investment
Measured daytime demand replaced the estimate the proposal had been sized on.

Lost to processing hours
Raw milk processed in expensive hours, found in the same data, fixed by scheduling.
Measure the chain before you commit the capital
An assessment establishes what your plant draws, stage by stage and hour by hour. That record is what a solar decision, a refrigeration upgrade and a tariff review should all be built on. Building that record is what sub-metering does, stage by stage from intake to despatch.
Where a buyer, a lender or a certification body wants the position in writing at a point in time, the same circuits are measured temporarily instead and reported as an energy audit.
