Quick answer
The return on a cold storage energy upgrade depends mainly on the measured baseline consumption, electricity tariff, running hours, how much of the load the measure actually affects, interaction with other measures, installed cost including downtime, and how savings will be verified. Use measured site data, state every assumption, and agree a measurement and verification method before purchasing.
Key takeaways
- What payback should a cold storage energy upgrade have? There is no universal figure.
- Can I add up savings from several measures? No.
- Does ColdMatch guarantee energy savings? No.

Energy upgrades in existing facilities are often sold with a headline payback. That figure is only as good as the assumptions behind it. This guide lists the assumptions to check and gives an original comparison table for common upgrade options.

Simple payback and its limits
Simple payback (years) = installed cost ÷ annual net savings
Annual energy savings = baseline kWh affected by the measure × expected reduction fraction × tariff
Simple payback ignores financing, maintenance changes, equipment life and the time value of money. For larger projects, use net present value or lifecycle cost as well.
The assumptions that matter
| Assumption | Why it matters | Where to get it |
|---|
|---|---|---|
| Baseline consumption | Savings are a share of real use, not nameplate | Sub-meters, utility bills, controller logs |
|---|
| Tariff and demand charges | Savings value varies by time of use | Utility contract |
|---|
| Running hours and seasonality | Measures save only when equipment runs | Controller data across a full season |
|---|
| Share of load affected | A door upgrade affects infiltration, not product load | Load breakdown from your engineer |
|---|
| Interaction between measures | Savings from two measures do not simply add up | Model packages together |
|---|
| Installed cost including downtime | Lost operating time is a real cost | Supplier quotes plus operations input |
|---|
| Maintenance change | Some measures add or remove service needs | Supplier and maintenance contractor |
|---|
Comparing common upgrade options
| Option | What it addresses | Main dependency | Verification idea |
|---|
|---|---|---|---|
| Controls and setpoint optimisation | Head pressure, suction, defrost logic | Plant can operate at revised settings safely | Compare normalised kWh before and after |
|---|
| Variable speed drives on compressors or fans | Part-load efficiency | Load profile with long part-load periods | Sub-meter the drive circuit |
|---|
| Condenser upgrade or cleaning | High condensing pressure | Ambient conditions and current condenser state | Trend condensing pressure vs ambient |
|---|
| Rapid doors, dock seals, air curtains | Infiltration and frost | Door traffic and dock activity | Door counters, defrost frequency, room stability |
|---|
| Insulation or panel repair | Envelope gains, moisture | Extent of damage | Thermal survey before and after |
|---|
| Heat recovery | Uses rejected heat on site | A real nearby heat demand | Meter recovered heat |
|---|
This table describes dependencies, not expected savings; results vary by site and must be estimated from your own data.
Verify savings after installation
Agree before purchase how savings will be measured. The International Performance Measurement and Verification Protocol (IPMVP) describes recognised options for measuring savings, including adjusting for weather and throughput. An ISO 50001 energy management system helps keep the baseline maintained over time.
Questions to ask suppliers
- Which baseline data did you use, and over what period?
- What share of site consumption does this measure affect?
- How were interactions with other measures handled?
- What downtime does installation require?
- How will savings be measured, and who pays for measurement?
