Why BESS pays for itself

Three reasons your CFO will say yes

30%+ peak charge reduction

Charge from cheap off-peak grid (or your own solar), discharge during expensive peak windows. Slash your kVA demand bill from month one.

Load shedding becomes a non-event

BESS sized for arbitrage gives you backup capacity for free — operations continue through Stage 4+ without diesel spend.

5-7 year payback, 15-20 year life

Modern LFP cells deliver 6,000+ cycles. Properly designed systems pay for themselves before mid-life and run another decade.

How energy arbitrage works

Buy low. Use high. Save the spread.

South Africa’s time-of-use tariffs and kVA demand charges create a gap of R1.50–R3.00/kWh between off-peak and peak rates. A properly sized BESS lets you trade that gap, every weekday, for 15+ years.

1

Charge cheap

Off-peak grid power (or daytime solar surplus) tops the battery up at low R/kWh rates.

2

Discharge expensive

Peak-period tariffs and kVA demand spikes pull from the battery instead of the grid.

3

Pocket the difference

Arbitrage spread × cycles per day × days per year = the saving line on your P&L.

Stibium Mine 5MW ground-mount solar installation

Real installation

5,068 kWp at Stibium Mine, Limpopo

SolarXgen’s largest project to date — a 5MW ground-mount solar array with diesel-displacement strategy for 24/7 mining operations. Generates over 8.7 GWh annually with an 83.1% performance ratio. Mining loads, peak-demand exposure and the tariff escalation curve are exactly the conditions where BESS arbitrage delivers the strongest ROI.
