Cold Storage & Pack-House Energy & Backup — Loads, Generators, Battery Storage & RFQ
In cold storage a two-hour outage during a heatwave writes off the load. Reciprocating and screw compressors also have brutal starting currents — genset sizing is dominated by inrush, not by kW-average.
Reference figures. Real specs and pricing come from the qualified suppliers that respond to your private RFQ. SeedMatchGroup does not resell equipment.
Core loads: refrigeration compressors, condensers, evaporator fans, cold-room lighting, pre-cooling / forced-air, hydro-coolers, defrost cycles and pack-house handling / weighing / labelling equipment.
Starting current is the sizing driver. Direct-on-line compressors need aggressive derates; soft-starters or VSD compressors dramatically shrink the genset kVA and improve fuel curves.
Typical load assumptions
Continuous vs peak vs critical (must-survive-an-outage) loads by project scale. Motor starting inrush is 4–7× nameplate for direct-on-line and ~1.5–2× on VFDs — genset kVA must cover the worst-case inrush without voltage collapse.
| Project scale | Continuous | Peak / inrush | Critical load | Runtime target |
|---|---|---|---|---|
| 50 t cold room | 8–15 kW | 25–45 kW | 6–10 kW | 24 h+ |
| 500 t cold store | 45–90 kW | 140–240 kW | 35–60 kW | 24 h+ |
| 2000 t cold + pack-house | 180–320 kW | 500–800 kW | 130–220 kW | 24 h+ |
| Multi-chamber DC (5000+ t) | 400–800 kW | 1100–1800 kW | 300–550 kW | 24 h+ |
Recommended generator & storage setups
Vendor-neutral reference stacks — diesel or gas generator, LFP battery storage, optional solar PV, ATS and controls. Hybrid stacks let solar and battery serve daytime load while the genset only starts on demand.
| Scale | Generator | Battery (LFP) | Solar PV | ATS / controls | Notes |
|---|---|---|---|---|---|
| 50 t | 60–80 kVA diesel | 20–40 kWh LFP | 20–40 kWp | ATS + soft-starter | Solar covers noon peak; genset absorbs start inrush. |
| 500 t | 300–400 kVA prime | 80–150 kWh LFP | 120–250 kWp | ATS + EMS + VSD compressors | VSD compressors halve genset size vs DOL. |
| 2000 t + pack-house | 800–1000 kVA prime | 250–500 kWh LFP | 400–800 kWp | Paralleling gear + full EMS | Hybrid pays back fast where grid tariffs peak. |
| 5000+ t DC | 1500–2500 kVA (parallel) | 800–1500 kWh LFP | 1000–2500 kWp | SCADA + EMS + demand response | N+1 compressors and gensets; peak-shaving with battery. |
- Specify VSD compressors — smaller genset, better part-load efficiency, no massive inrush.
- N+1 compressor redundancy on any store above 200 t.
- Solar-first hybrid where daytime grid tariffs are high — cold storage load matches solar profile.
- Battery peak-shaving to cut grid demand charges (often > kWh cost).
- Temperature loggers and door alarms tied into UPS-backed controls.

FAQ
- How are these load assumptions derived?
- Figures are reference values from typical commercial projects — real numbers depend on climate, crop, motor selection (DOL vs VFD), controls topology and outage-risk tolerance. Use them to frame the RFQ; final sizing is confirmed by the winning EPC and OEM as part of the engineered proposal.
- Do these setups include ATS, UPS and controls?
- Yes. Every recommendation assumes an Automatic Transfer Switch on the incoming feed, a UPS on the climate computer / control cabinet, and a supervisory controller (EMS) if a hybrid stack is specified. This is a single, integrated procurement package — not three separate purchases.
- Does SeedMatchGroup sell generators or batteries?
- No. SeedMatchGroup is a human-led global sourcing platform supported by proprietary technology. The full energy stack — generator, battery, inverter, ATS, UPS, EMS — is specified inside your RFQ and opened privately to qualified global suppliers and integrators.
