Load & tariff modelling
12-month interval data feeds a dispatch model that sizes the BESS against your specific tariff, demand structure and PV profile.

Commercial battery storage, engineered for revenue.
Tier-1 lithium iron phosphate battery storage from 50 kWh to 20 MWh — behind-the-meter or front-of-meter — modelled against demand-charge reduction, FCAS, wholesale arbitrage and Federal + state rebate stacks.
01 — Overview
Commercial battery storage only pays back when it's sized against a real load profile and dispatched against a real revenue stack. ESQ builds BESS business cases from your 12-month interval data — solving for demand-charge shaving, PV self-consumption, wholesale arbitrage, FCAS/PDRS certificate revenue and backup — before we spec hardware. National delivery of Tesla Megapack, Sungrow, PowerPlus, Fluence, BYD and Delta systems.

02 — Capabilities
What ESQ delivers across this practice.
BS-02
Demand-charge reduction
Peak-shaving algorithms target kVA maximum demand, often the fastest ROI lever on commercial tariffs.
BS-03
FCAS & PDRS revenue
Contingency FCAS, Regulation FCAS and NSW Peak Reduction Certificates modelled into every business case where the site qualifies.
BS-04
PV self-consumption & firming
Shift excess PV into evening loads and firm PV output for sites facing curtailment or export limits.
BS-05
Backup & islanding
UPS-grade backup for critical loads with seamless islanding on grid failure — including generator paralleling where required.
BS-06
Financing & PPA structures
CAPEX, operating lease, chattel mortgage, and shared-savings PPA structures via our finance panel — cash-flow-positive from month one for eligible sites.

04 — FAQs
Common technical questions.
- How big should our battery be?
- Battery sizing should always follow the dispatch model, not a rule of thumb. We size against your actual interval data and the revenue streams available at your site — typically resulting in a smaller, faster-payback system than sales-led estimates.
- What's a realistic payback?
- Behind-the-meter BESS with meaningful demand charges typically pay back in 4 – 7 years standalone, and 3 – 5 years when stacked with PDRS, FCAS or VEECs where available.
- Do you offer PPA or financing?
- Yes. CAPEX, chattel mortgage, operating lease and shared-savings PPA structures are available via our finance panel. Many commercial BESS projects are cash-flow-positive from month one.
- Which battery brands do you install?
- Tier-1 LFP only — Tesla Megapack, Sungrow, PowerPlus, Fluence, BYD, Delta, and others. We're brand-agnostic; the right hardware depends on scale, revenue stack and installation footprint.
- Can we participate in a VPP?
- Yes. Where the site's dispatch profile allows, we integrate to major VPPs (AGL, Origin, Amber, Discover Energy, EnergyLocals) so surplus capacity earns revenue when it isn't needed on site.
