50kW engineered for Cold Storage Facilities in Welkom
High Eskom tariffs and power instability directly affect cold storage facilities operations across Welkom, Lejweleputswa. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Welkom sit on the N1 and R30 corridor, where cold-chain spoilage risk during outages make generation on site the lowest-risk hedge available.
End-to-end Small-Scale Embedded Generation applications with your municipality or Eskom distribution office. Cold Storage Facilities carry a load profile dominated by 24/7 refrigeration compressors with high startup currents, which is exactly where solar generation overlaps hardest with your billing peaks.
Pair your cooling, refrigeration and commercial aircon systems directly with solar PV generation to cut high peak-demand electrical charges. Thermal pre-cooling during peak irradiance hours shifts chiller demand off the Matjhabeng Municipality account entirely.
Local grid and industrial context
- Distribution authority: Matjhabeng Municipality, feeder capacity confirmed before design freeze
- Industrial corridor: N1 and R30 corridor
- Goldfields mining belt
- HVAC and refrigeration load coupling assessed on every cold storage facility audit

Questions from Welkom operators
How long does a 50kW installation in Welkom take?
A 50kW plant on a cold storage facility in Welkom typically takes 4 to 10 weeks from signed order, including structural assessment, Matjhabeng Municipality SSEG paperwork and commissioning.
Do we need approval from Matjhabeng Municipality?
Yes. Any grid-connected embedded generation in Welkom, Lejweleputswa must be registered as SSEG. Reyds handles the full application, professional engineer sign-off and NRS 097-2-1 compliance documentation.
Can the system run our aircon and refrigeration during load shedding?
With hybrid inverters and LFP storage, cooling, refrigeration and commercial aircon can be carried through outages while also clipping peak-demand charges on your cold storage facility account.
