Industrial Transformer & Power Upgrades Sydney
Pad-mount, pole-mount and kiosk transformer installations, kVA capacity upgrades and network-approved power connections for Sydney factories, warehouses, construction sites and commercial developments.
⚡ Quick Answers: Industrial Transformer & Power Upgrades
- What is an industrial transformer upgrade? It increases the electrical capacity feeding your site, usually via a dedicated pad-mount, pole-mount or kiosk transformer rated in kVA.
- Do I need network or council approval? Yes, a design and connection approval from Ausgrid, Endeavour Energy or Essential Energy is required, and some sites also need council development approval.
- What's the difference between pad-mount and pole-mount? Pad-mount units suit higher capacities (315 kVA+) on ground-level sites, while pole-mount units suit smaller, single-tenant sites up to around 315 kVA with no ground compound required.
- Can High Demand Electrical manage the full connection? Yes, as a Level 2 ASP (Licence 397193C) we work directly on network assets, including transformer connections, service mains and metering, without waiting on distributor crews.
- How long does an upgrade take? Network design approval typically takes several weeks, and physical installation ranges from a few days for a pole-mount connection to several weeks for a pad-mount or kiosk substation with civil works.
- How much does it cost? Cost depends on transformer capacity, whether the connection is overhead or underground, network augmentation charges and civil works, and a maximum demand assessment gives you a fixed, itemised quote.

Industrial Transformer & Power Upgrades Sydney
When a Sydney business outgrows its electrical supply, whether that's a factory adding production lines, a warehouse fitting out an EV fleet, or a mixed-use development with rooftop plant, the fix usually isn't a bigger switchboard. It's more capacity coming into the site in the first place.
High Demand Electrical designs and installs industrial transformer and power upgrades across Sydney, working as an accredited Level 2 ASP (Licence 397193C) on everything from pad-mount and pole-mount transformer connections to 200A and 400A supply upgrades, service mains installation, and the switchboard work that has to happen behind them.
We coordinate directly with Ausgrid, Endeavour Energy and Essential Energy, so the network approval, the physical installation and the compliance paperwork move as one project instead of three.

Why Sydney Sites Need More Than A Switchboard Fix

Rising load demand
New machinery, EV fleets, cool rooms and extra tenancies draw more than a standard supply can handle.

Compliance & insurance

Industrial Transformer & Power Upgrades
What an Industrial Transformer & Power Upgrade Involves
Maximum Demand Assessment
Pad-mount, pole-mount or kiosk substation, matched to the load and site constraints, and pole-mount connections often pair with a private power pole installation.
Every upgrade starts with an accurate maximum demand assessment, so the new transformer is sized to the site's real load rather than a rough guess.
Transformer Selection & Supply
Pad-mount, pole-mount or kiosk substation, matched to the load and site constraints, and pole-mount connections often pair with a private power pole installation.
Network Coordination
Design submission and connection offer management with Ausgrid, Endeavour Energy or Essential Energy, handled directly by our Level 2 ASP team.
Supply & Service Mains
200A and 400A supply upgrades, plus underground or overhead service mains and consumer mains installation sized to the new transformer output.
Switchboard & Switchgear
Main switchboard and switchgear upgraded to match the new capacity. See our dedicated switchboard upgrades page for scope and typical timeframes.
Many transformer jobs run alongside a full switchboard and service mains upgrade, so downstream boards can handle the extra capacity too.
Certification & Sign-off
Testing, energisation and full commercial electrical compliance documentation, so the site is audit-ready from day one.

Which Transformer Type Fits Your Site
Ground-level
Pad-Mount
A fenced, ground-level unit for sites with room for a compound. The default choice for larger industrial loads.
Capacity
315–2500 kVA
Best for
Industrial estates, large warehouses
Pole-mounted
Pole-Mount
Mounted on a dedicated private power pole, with no ground compound required, and suited to tighter or single-tenant sites.
Capacity
25–315 kVA
Best for
Single-tenant factories, fringe-industrial sites
Enclosed
Kiosk Substation
A compact, secure enclosure suited to multi-tenant sites, and common on strata and commercial developments where space and noise matter.
Capacity
500–2500 kVA
Best for
Strata, shopping centres, mixed-use sites

How It Runs
Our Industrial Power Upgrade Process
Site Assessment & Maximum Demand Calculation
We measure existing load, model projected growth, and confirm the transformer capacity the site actually needs.
Network Application & Design Approval
Design submission and connection offer negotiated with Ausgrid, Endeavour Energy or Essential Energy on your behalf.
We manage the full network application and design approval process directly with your distributor, so there is no back and forth on your end.
Transformer Procurement & Civil Works
Pad, pole or kiosk works prepared to network and council specification ahead of delivery.
Level 2 ASP Installation & Connection
Physical installation and network-side connection carried out under our own Level 2 accreditation, with no waiting on distributor crews for every step.
Switchboard & Service Mains Upgrade
Downstream switchboard, switchgear and mains upgraded to safely carry the new supply.
Testing, Certification & Energisation
Full compliance sign-off, with documentation that heads off future defect notices, not just a working meter.
Every job wraps up with full testing, certification and energisation, so the paperwork is ready if your insurer or the network operator asks for it.

Why High Demand Electrical
Accredited for the Network-Side Work, Not Just the Switchboard
As a Level 2 ASP (Licence 397193C), we're accredited to work directly on and near network assets, which is the part of a transformer upgrade most electricians have to subcontract out. That means one point of contact for design, connection and switchboard work, and one Level 2 team responsible for getting it certified.
If undersized supply has already led to a compliance issue, our defect notice rectification service can bring the site back into line as part of the same project.
Frequently Asked Questions
FAQs
What is an industrial transformer upgrade and when do I need one?
It increases the electrical capacity feeding your site, usually via a dedicated pad-mount, pole-mount or kiosk transformer rated in kVA. You need one when new machinery, EV fleets, cool rooms or extra tenancies push demand past what your current supply can safely carry.
How much does an industrial power upgrade cost in Sydney?
Cost depends on the transformer capacity, whether the connection is overhead or underground, network augmentation charges, and civil works. A maximum demand assessment gives you a fixed, itemised quote.
Do I need network or council approval for a transformer upgrade?
Yes, a design and connection approval from Ausgrid, Endeavour Energy or Essential Energy is required, and some sites also need council development approval. We manage this process as part of the project.
Not sure which network area your site sits in? You can check your network area in seconds with our postcode network checker.
How long does an industrial transformer installation take?
Network design approval typically takes several weeks; physical installation ranges from a few days for a pole-mount connection to several weeks for a pad-mount or kiosk substation with civil works.
What's the difference between a pad-mount and pole-mount transformer?
Pad-mount units sit in a fenced ground-level enclosure and suit higher capacities (315 kVA+), typically industrial estates and large warehouses. Pole-mount units are smaller (up to ~315 kVA) and suit single-tenant factories and smaller commercial sites.
Can High Demand Electrical manage the full connection as a Level 2 ASP?
Yes. Our Level 2 ASP accreditation (Licence 397193C) lets us work directly on and near network assets, including transformer connections, service mains and metering, without waiting on distributor crews for every step.
