Where commercial batteries pay back fastest
Peak-demand reduction
Capacity charges of $15–$45/kVA/month can dominate a C&I bill. Batteries shave the peak and save thousands monthly.
Time-of-use arbitrage
Charge from solar or off-peak grid, discharge during shoulder/peak rates to capture a 20–40 c/kWh spread.
Backup & resilience
Refrigeration, POS, EFTPOS and lighting stay live during grid outages — protecting stock and revenue.
