What a business battery does for you
A commercial battery rarely pays back on one saving. Here are the six applications a business battery can serve, and how they stack — each with its own sizing, economics, and payback.
Peak Shaving & Demand Management
200–1,000 kWh · 100–500 kW. Red-band DUoS avoidance · Available-capacity (kVA) charge reduction.
Solar-Plus-Storage
100–500 kWh · 50–250 kW. Solar self-consumption uplift · Avoided low-value export.
Energy Arbitrage & Time-of-Use
215–860 kWh · 100–430 kW. Off-peak to peak arbitrage on a time-of-use tariff · Wholesale/day-ahead price spread capture.
Backup Power & Resilience
150–800 kWh · 75–400 kW. Uninterruptible ride-through / islanding · Diesel-genset displacement.
EV Fleet Charging Buffer
200–1,000 kWh · 150–600 kW. Grid-upgrade avoidance for high-power charging · Charging-window arbitrage.
Grid Services & Revenue Stacking
500–2,000 kWh · 250–1,000 kW. Capacity Market agreements · Frequency response (Dynamic Containment/Moderation/Regulation).

What we will not do
- Your details are used only to reply to you. There is no installer partner behind this site and nothing is passed on.
- No marketing list, no newsletter sign-up, no unsolicited calls.
- We do not sell, install or quote for batteries, so there is no system to oversize and no payback to inflate.
