volt Engineering Pty Ltd

Power systems engineering that takes generation from potential to possible.

Substations. Automation. Control centres. Telecoms.
Vendor-independent engineering across the whole asset — feasibility, design, construction, commissioning and the contract that holds it together.

Capabilities

The primary plant, the control system, and everything in between.

Most of what goes wrong on a power project happens at the boundaries — between the switchyard and the control room, between the protection engineer and the comms vendor, between the design and the contract. We work across all of them, vendor-independent, so those boundaries are ours to manage rather than yours.

Power

Substation engineering

Primary and secondary design from concept to energisation, with the feasibility work that sets the scope before it.

  • Concept & feasibility studies
  • Primary plant, layout & earthing
  • Protection & control design
Automation

Substation automation & RTU

IEC 61850 station architecture, and the RTUs and IEDs that make a substation observable and controllable from anywhere.

  • SAS architecture & specification
  • RTU design & integration
  • Station bus, GOOSE & interlocking
Control centre

SCADA, EMS, GMS & DMS

Control-centre platforms configured around how the room actually runs, not how the manual assumes it does.

  • System design & feasibility studies
  • Network, generation & distribution models
  • Multi-vendor integration & migration
Operators

HMI design & configuration

Displays and alarms built so an operator sees the problem at three in the morning, not the decoration around it.

  • Display hierarchy & navigation
  • Alarm rationalisation & philosophy
  • Historians, trends & reporting
Telecoms

Telecommunications networks

The transport layer that carries protection signalling and telemetry between sites, designed for the latency protection actually needs.

  • SDH, MPLS & DWDM networks
  • Power line carrier (PLC)
  • Microwave links & path surveys
Voice

PABX & operational voice

Operational telephony that keeps working when the network doesn't — control room, depot and switchyard on one system.

  • PABX design & replacement
  • Operator & dispatch telephony
  • Integration with control-room systems
Auxiliary

DC & auxiliary power

The supplies everything else quietly depends on. When a substation fails to trip, this is often why.

  • 48 V DC & 110/125 V DC systems
  • Battery & charger sizing, UPS
  • Ancillary & auxiliary AC supplies
Convergence

IT/OT solutions

Operational networks, data platforms, and a defensible security boundary between the two domains.

  • OT network architecture
  • Data integration & historians
  • OT cyber-security hardening
Delivery

Substation & line construction

Construction engineering and site delivery for substations, overhead lines and cable routes.

  • Construction packages
  • Site engineering & supervision
  • Testing, commissioning & energisation
Across every discipline

Troubleshooting & technical investigation

When a system misbehaves, we go and find out why — nuisance alarms and bad data, protection that operated when it shouldn't have, comms that drop under load, a migration that stalled halfway. Independent investigation, a documented root cause, and the fix. We are just as willing to conclude that the problem isn't where everyone assumed it was.

How we deliver

One party accountable for the whole lifecycle.

We can take a scope from first feasibility study through to a warranty period — carrying the contract administration, cost control, programme and risk alongside the engineering. That means one commercial relationship and one throat to choke, instead of you coordinating a designer, a contractor, a comms vendor and a SCADA integrator who each blame the others.

01

Feasibility

Options studies, concept design, cost estimates and business-case input.

02

Detailed design

Full design packages, specifications, drawings and studies for construction.

03

Procurement

Tender documentation, vendor evaluation, contract negotiation and award.

04

Construction

Site engineering, supervision, quality assurance and progress reporting.

05

Commissioning

FAT and SAT, protection testing, energisation and handover documentation.

06

Support

As-builts, operator training, defect resolution and ongoing investigation.

The team

Engineers who have sat on every side of the table.

Volt Engineering is a team of power systems engineers delivering SCADA, substation automation and grid modernisation — from a single protection scheme to a national programme. We have worked inside transmission utilities, inside turbine manufacturers, and inside EPC and consulting firms, which is why the interfaces between those parties are the part of a project we are most comfortable owning.

Work at national scale

Our team currently leads a nationwide SCADA and Energy Management System rollout for a national transmission operator — more than 200 grid stations and 170 RTU sites, among the largest transmission-grid modernisation programmes in South Asia. That includes the control centre itself: SCADA and EMS at both the national and backup control centres, giving operators real-time visibility of power flows across the transmission operator, the distribution companies and the bulk power consumers.

Around it sits the infrastructure that makes it possible — 4,000 km of OPGW fibre, a national microwave backbone, SDH and digital power line carrier integration, revenue metering, and 48 V DC backup systems across more than 200 sites. Legacy donor-funded SCADA infrastructure was folded into the new system with no disruption to national grid operations.

We carry that work with full technical, commercial and contractual accountability — the engineering and the contract, not one without the other.

A first for the Australian market

Earlier in our history, our engineers built the first dedicated IEC 61850 test-bed system in the Australian energy market, laying the technical foundation for utility-wide rollout of next-generation substation automation. Five years inside a state transmission utility followed — commissioning RTU and HMI systems, integrating protection relay schemes, and keeping SCADA alive through station rebuilds on a critical state-wide network.

Renewables, end to end

On the generation side, we have owned wind farm SCADA across its whole life — pre-sales and design, through configuration and commissioning, to long-term servicing. Park controllers, balance-of-plant substation RTUs, and the grid-compliance testing with market and network operators that turns a finished wind farm into a connected one.

That work has run in parallel with global R&D teams, adapting SCADA platforms to regional grid codes rather than forcing one template onto every market.

Why it matters to you

Having worked every seat, we know how a grid operator thinks about risk, how a vendor scopes a contract, and how a contractor prices ambiguity. We are hard to surprise.

It also means we are genuinely vendor-independent. We do not resell anyone's platform, so the recommendation you get is the one that suits your network — including, often, keeping what you already own and making it work properly.

The team is Master's-qualified in power systems, automation, control and communications, and works to Australian standards and market-operator compliance as a matter of course.

Different regulators, different grid codes, different site realities. Projects that assume one country's assumptions travel badly — we have learned where they break, and we design for the network in front of us.

Problems found in a design review are cheap. Problems found at energisation are not.

We don't resell anyone's platform, so the recommendation you get is the one that fits your network — including the option of keeping what you already own.
