30kW engineered for Filling Stations in Welkom
High Eskom tariffs and power instability directly affect filling stations 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 lost trade the moment supply drops make generation on site the lowest-risk hedge available.
Zero-capex Power Purchase Agreements and rental structures - you pay only for the solar kWh you consume. Filling Stations carry a load profile dominated by fuel pumps, forecourt lighting and convenience refrigeration, 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

Questions from Welkom operators
How long does a 30kW installation in Welkom take?
A 30kW plant on a filling station 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 filling station account.
