Calculator, commercial battery payback
Commercial Battery Payback Calculator
Estimate an indicative payback range for a commercial battery from peak demand-charge reduction and tariff arbitrage.
Assumptions
Indicative installed cost ≈$6,000/kW of battery power capacity · demand-charge rate ≈$12/kW/month · achievable peak reduction 20–40% depending on load shape · tariff-structure multiplier applied. Real figures require your interval and tariff data.

02Methodology
How we estimate battery payback for commercial clients.
We size an indicative battery against your peak demand, apply a typical demand-charge rate and achievable peak-reduction range, adjust for your tariff structure, then compute payback. Arbitrage and additional VPP or PDRS value can further shorten payback.
