Battery Energy Storage Systems (BESS)

ONE LOOP ENGINEERING

Who It's For

Commercial and industrial facilities looking to reduce energy costs and unlock new revenue streams.

  • Manufacturing plants and industrial facilities with high demand charges
  • Businesses with existing solar looking to add storage
  • Sites requiring backup power or power quality support
  • C&I operators seeking FCAS and wholesale market participation.

Typical System Size (Energy Capacity)

200 kWH–20 MWh

Our BESS solutions go beyond simple battery installation. We engineer complete energy storage systems with advanced control algorithms designed for optimal grid interaction, revenue stacking, and long-term performance — from initial design through grid connection approval and ongoing optimisation.

CORE CAPABILITIES

System architecture

Connection Interface & Compliance Delivery

Designs the grid interface and compliance pathway for C&I DER installations. Includes settings, test plans, commissioning evidence, and documentation aligned to DNSP requirements, ensuring predictable approvals and safe ongoing operation.

Demand Charge & Peak Management

Engineers behind-the-meter control strategies to cap maximum demand, manage peak events, and stabilize site import/export. Includes metering architecture, control setpoints, and dispatch logic aligned to tariff structure and operational constraints.

VPP + FCAS Market Enablement

Designs the controls, metering, and telemetry stack required for VPP orchestration and FCAS participation. Includes dispatch interfaces, response-time tuning, availability and constraint logic, and compliance-aligned testing to support market registration and ongoing performance verification (subject to aggregator and AEMO requirements).

STRATEGIC IMPACT

Value Delivered

Cost Savings

Lower your energy bills by using solar and storage to reduce peak demand, shift consumption, and smooth price volatility, without disrupting operations.

A critical facility remains brightly lit during a storm-driven power outage, highlighting reliable backup power and continuity.

Resilience

Keep critical loads running through outages with seamless backup and intelligent load prioritisation, designed around your uptime requirements.

Revenue Generation

Turn flexible capacity into a cash-flow asset through VPP services and ancillary market participation pathways, where eligible and approved.

Delivery Scope

  • Site assessment, load profiling, and financial modelling.
  • System design, equipment procurement, and installation coordination.
  • Grid connection management and regulatory approvals.
  • Control system integration (Amber or hardware-agnostic alternatives).
  • Ongoing performance monitoring and revenue reporting.
Why One Loop

Why One Loop

Most battery installers stop at the hardware. We don't. One Loop engineers the complete system — control logic, grid interaction strategy, and revenue stacking — so your BESS works harder from day one.

We're hardware-agnostic and market-fluent. Whether you're targeting FCAS, wholesale arbitrage, or demand charge reduction, we design the strategy around your site, not around a product catalogue.

FAQ

Frequently Asked Questions

Can you work with equipment or systems we already have on site?

In most cases, yes. We assess your existing assets first and design the most cost-effective integration path rather than recommending a full replacement by default.

Do you manage grid connection and regulatory approvals?

Yes. We handle the full compliance pathway — DNSP approvals, commissioning documentation, and any market registration required for your system to operate legally and optimally.

Do you only work with specific equipment brands?

No. We are hardware-agnostic. We select equipment based on your site requirements, performance specifications, and budget — not supplier agreements.

How do you determine the right system size for our site?

We start with your load data, energy bills, and operational requirements. Every system is sized through detailed modelling and simulation before any equipment is specified.

What does ongoing support look like after commissioning?

We provide performance monitoring, operational reporting, and strategy optimisation as an ongoing service — because a system that isn't continuously tuned rarely performs to its full potential.
