Commercial battery storage for Australian sites
If your site spends more than AUD 5,000 per month on electricity — or runs on a tariff with a peak demand charge — battery storage can shift load, cap demand and reduce bill exposure. Raylin Energy is the EPC general contractor for commercial battery storage projects in Australia, and assesses sites from 200 kWh to 10 MWh. We sign the project contract and remain your single accountable party for equipment, design, operations and after-sales. Construction is delivered by qualified, licensed Australian subcontractors we select and manage.
Three ways a battery changes your electricity bill
The exact savings depend on your tariff, load profile and operating hours. We outline the three mechanisms we see most often on Australian commercial sites.
On most Australian commercial tariffs, the peak demand charge is the single largest line item. By discharging the battery during your highest-demand window, the grid-drawn peak is capped. The effect is largest on sites with a clear single shift or a recurring process peak — for example, a cold storage load, a packaging line, or a charger cluster.
On time-of-use tariffs, the difference between off-peak and peak rates is often 2–4×. A battery charged from the grid (or your own solar) during the cheap window and discharged during the peak window moves consumption to the cheapest hours. Most effective for sites with steady daytime load and little night operation.
For sites where a short outage costs product, downtime, or safety risk — cold storage, food processing, manufacturing controls — a battery in UPS-mode keeps the critical sub-panel running through a brief grid event without waiting for a diesel to start.
Real savings depend on your specific tariff, your load profile and your operating hours. We will not give you a percentage figure before we have seen a recent bill. A free assessment starts with that.
A starting range, not a final number
Every site is different. The ranges below are where most of our commercial battery enquiries land. Below 200 kWh or above 10 MWh we still talk to you, but the assessment is more involved.
Small factories, retail cold rooms, light manufacturing. Often paired with existing rooftop solar. Common starting point for sites that already pay demand charges above 80 kVA.
Food processing, plastics, packaging, warehousing, building materials. Usually sized to cover the 3–6 hour peak demand window. Often combined with rooftop or ground-mount solar.
Cold storage, meat processing, continuous manufacturing, large industrial facilities. Requires detailed network connection review and benefits from solar co-design.
261 kWh modular liquid-cooled cabinet
Our C&I platform is built around a 261 kWh all-in-one liquid-cooled cabinet. It is the unit we quote, configure and warranty-manage — scaled by cabinet count rather than by a different product per site size.
261 kWh per cabinet
Nominal DC energy per cabinet. Indicative usable values are based on 95% operating depth of discharge and exclude auxiliary consumption.
125 kW AC per cabinet
Rated AC output per cabinet through the integrated PCS. Power and energy scale independently, so a site can take more cabinets at the same peak or more peak at the same energy.
Liquid-cooled enclosure
Liquid cooling manages cell temperature across the full charge/discharge window, which is what allows sustained output on a hot summer afternoon in NSW and QLD.
Three common cabinet configurations
Indicative project ranges only. Final system configuration and usable energy are subject to project-specific engineering and assessment.
Commercial buildings, hotels and hospitality facilities. Typically paired with existing rooftop solar or used for tariff peak management on a single-phase-derived supply.
Factories, logistics centres and agricultural facilities. Sized to cover a multi-hour demand window rather than a single peak event.
Large industrial sites, logistics hubs and business campuses. Requires a full network connection study, protection coordination and staged commissioning plan.
A single product platform scales to 20 cabinets (~5 MWh). Projects above that — up to 10 MWh — are delivered across multiple platforms on the same architecture, which is why we quote to 10 MWh rather than stopping at one cabinet family. Indicative energy values do not constitute a final program usable-capacity determination; that is confirmed per project after engineering review.
High electricity load, time-sensitive production
Battery storage pays back fastest where electricity is a significant operating cost and there is some flexibility in when that electricity is consumed.
Food processing
Refrigeration, mixers, packaging lines. Long operating hours and demand charges make load shifting attractive.
Meat processing
Continuous refrigeration load. Strong candidate for battery backup and demand-cap.
Cold storage
24/7 refrigeration load. Backup power protects product and avoids costly restart cycles.
Manufacturing
Shifts, motors, processes. Demand charges dominate the bill; load shifting and peak shaving both apply.
Packaging
High-throughput lines with predictable load profiles. Battery sized to the consistent daily peak.
Plastics
Process heating, extruders, injection moulding. Energy intensity makes storage + solar highly relevant.
Building materials
Crushing, kilns, batching. Heavy demand charges — even small peaks matter at scale.
Warehousing
Material handling, charging, lighting. Battery + solar covers daytime loads; backup for racking / WMS.
From enquiry to commissioning, in six steps
The exact timeline depends on your site, network connection requirements and equipment availability. This is the typical shape of a 200 kWh–10 MWh project. The role for each step is named so you know who is doing what.
You submit
You complete the assessment form — about five minutes. Your latest electricity bill, site address, operating hours, and optional photo or one-line description of the site.
Charlene replies
Charlene (our lead engineer, Sydney) reads your enquiry and replies from charlene@raylin-energy.com within one business day with a sizing range and any follow-up questions.
We assess your bill
We analyse your tariff, demand profile, and operating hours. If a full assessment is not justified at this stage, we tell you — and explain what would change that.
We send a written proposal
After a short call, we provide a sizing recommendation, indicative pricing, published-program incentive guidance, and a project timeline. All in writing so you can compare.
We supply + your installer installs
Once terms are agreed, we mobilise the equipment and our selected Australian construction subcontractor. Network connection approval is managed end-to-end (Ausgrid / Endeavour / Essential Energy in NSW, Citipower / United in VIC, Energex / Ergon in QLD). You deal with one contract — ours.
Commission & handover
Commissioning, documentation, and handover. We do not employ in-house Australian installation crews — site work is done by accredited local partners under your project.

Only an accredited party can lodge and warrant the application; we prepare and manage the evidence, EcoVantage holds the accreditation and makes the submission. We will tell you which applies to your project before you commit to anything.
EPC general contractor, accredited partners
Raylin Energy is the EPC general contractor for the project. We sign the project contract and remain your single accountable party. Our scope covers equipment supply, system design, network connection approval, long-term operation and after-sales support. Construction is delivered by qualified, licensed Australian subcontractors — typically CEC-accredited solar and battery installers and licensed electricians — that we select and manage. We do not employ in-house Australian installation crews; every project is built by accredited local trade partners under our direction.
6 across Australia
Sydney · Melbourne · Brisbane · Adelaide · Perth · Townsville. Stock and dispatch are quoted per warehouse so freight and lead time are clear before order.
ISO 9001 quality management
Our supply and warehouse operations are run under an ISO 9001 quality management system. Equipment is CE / IEC / AS-NZS compliant and traceable to source.
CEC-accredited installer network
Site work is done by licensed electricians and CEC-accredited solar / battery installers in your state. We do not employ in-house installation crews.
One contract with us, three accredited parties working under it
A commercial storage project touches parties who each hold a separate statutory responsibility. We are the prime contractor and hold the contract with you; the other parties do their own accredited scope and keep their own obligations.
Your single point of accountability
Project origination and scoping, product and solution coordination, supply chain and commercial management, manufacturer interface, warranty and technical escalation. One contract, one project manager, one escalation path.
Licensed, on your site
Site preparation, mechanical and electrical installation, protection settings, testing and commissioning. Carried out by licensed electricians and CEC-accredited installers holding their own licences and insurance.
EcoVantage — ACP for NSW PDRS
Product pre-eligibility assessment, evidence review, audit and certificate processing under the NSW PDRS or other applicable scheme. We prepare and manage the technical evidence; only the accredited party can lodge it.
Network connection is submitted to and approved by your network service provider — no party can shortcut that. Each accredited party retains its own statutory responsibilities; being under our contract does not transfer their licensing obligations, and we do not represent otherwise.
The 261 kWh cabinet, deployed at scale
These sites were delivered by our manufacturing partner on the same 261 kWh liquid-cooled platform we supply and warranty-manage in Australia. The configuration ladder runs from a single cabinet at 100 kW to 28-cabinet systems in the multi-megawatt-hour range, with the same enclosure family in between.
How to read these images. They are reference projects on the same 261 kWh platform our Australian customers receive — delivered by our manufacturing partner, supplied and warranty-managed in Australia by Raylin Energy. We do not present them as Raylin's own delivered projects. If you are evaluating us and would like an Australian reference call in your industry, email Charlene and we will arrange one.
Two arrangements that shorten the path from enquiry to commissioning
These are not product features — they are two external arrangements we have set up around the project, so customers do not have to find them separately.
EcoVantage handles BESS5 certificates
Where an NSW PDRS BESS5 certificate applies to your project, EcoVantage is the accredited certificate provider on our side. They handle product pre-eligibility review, evidence assembly, audit and certificate processing. We prepare and coordinate the technical evidence on your behalf; EcoVantage makes the submission under their accreditation. You receive one project manager on the Raylin side, and one accountable ACP across the certificate path.
EcoVantage is one of the accredited certificate providers registered under the NSW PDRS. Where a project does not qualify under BESS5, or where a different scheme applies, we tell you up front rather than lodging under the wrong category.
Official policy references. The Peak Shifting (BESS5) category is published on the NSW Energy Savings Scheme site: Peak Shifting (BESS5) · PDRS Rule and BESS5 requirements. Check these for the current criteria, capacity window, and any rule changes since our last update.
Westpac finance pathway on referral
For commercial customers who want to finance the project rather than pay upfront, we have an arrangement with Westpac through which we refer eligible customers directly to the bank. Westpac assesses each customer on its own terms — the project, the customer, the cash-flow case, the security position. Finance is at the bank's discretion; approval is not guaranteed, and we do not represent otherwise.
This is a referral arrangement, not a co-marketed finance product. If a customer's situation does not suit the Westpac pathway, we can still proceed on direct purchase or on the customer's own finance.
What you should know before we talk
We would rather not work with you than mislead you. These are the things we will not say.
- We do not claim to employ in-house Australian installation crews. On-site installation is delivered by accredited local partners.
- We do not guarantee government incentive, grant or rebate outcomes. We will tell you what is currently published and help you assess eligibility — the application and approval are between you and the program administrator.
- We do not guarantee specific savings, payback periods or return on investment. Those numbers depend on your tariff, your load profile, your operating hours and your future electricity prices. We will not give you a payback figure before we have seen your bill.
- We do not publish project case studies or customer reviews that we cannot verify with the named customer.
Common questions from commercial sites
What size battery storage do I need?
Sizing depends on your average load, peak demand, tariff structure and operating hours. A typical starting point is matching the battery power (kW) to your peak demand window and the energy (kWh) to the duration you need to shift. We assess your bill and load profile to recommend a starting range before any site visit.
Do you install the systems yourselves?
Raylin Energy signs the EPC general contract. We take single-point accountability for the project including equipment, design, network connection approval and long-term operation. Construction is delivered by qualified, licensed Australian subcontractors — electricians and CEC-accredited installers — that we select and manage. We do not employ in-house installation crews; every site is built by accredited local partners working under our project management.
How long does a commercial battery project take from approval to commissioning?
Typical lead times for a 200 kWh – 10 MWh project range from 10 to 26 weeks once supply terms are agreed, depending on equipment availability, network connection requirements and site readiness. We provide a project timeline after the assessment.
Can you help with NSW or federal government incentives?
We provide guidance on currently published NSW, federal and ARENA-related programs that may apply to your project. Final eligibility, application and approval are between you and the relevant program administrator. Raylin does not guarantee funding outcomes.
What information do you need for an assessment?
A recent electricity bill (PDF or photo), your operating hours and approximate load profile, your site address and any existing solar PV information. The assessment form on this site collects the essentials; we follow up for any detail we still need.
Will you share my information with advertising platforms?
No. We do not upload your enquiry data to Google Ads or other third-party advertising audiences. Aggregated, anonymous conversion counts may flow to Google Ads for measurement only, with no personal data attached.
