What we do

One team across the power & energy lifecycle

Specialist high-voltage engineering and complete assets care — engineer, design, procure and install through to test, commission, maintain and clean.

HV testing & commissioning

FAT & SAT, protection systems, primary injection, HIPOT and energisation for substations and power stations up to 500kV.

Solar cleaning & maintenance

Scheduled cleaning, inspection and preventative maintenance that recovers lost generation for farms and buildings.

Solar installation & T&C

Design, install, test and commission solar farms and rooftop systems — protection relay and anti-islanding proving included.

Protection & secondary systems

Relays, SCADA/DCS, metering, IEC 61850/GOOSE, protection studies, settings and scheme testing.

Energy management

Industrial & commercial energy audits, power factor correction, harmonics and demand management.

Engineering & EDPC

Engineer, design, procure and construct — plus design review, project management and substation earth grids.

Our work

Two decades on critical infrastructure

Our crews have tested and commissioned switchyards, substations and power stations for the biggest names in energy and resources — and that same discipline keeps solar assets performing.

  • Tier-one deliverySamsung, Siemens, Schneider Electric, SP-AusNet, EPC and more.
  • Up to 500kV, onshore & offshoreSubstations, GIS, transmission lines, power stations and LNG.
  • Full safety & QAJHA / JSEA / SWMS, ITPs and as-tested documentation on every job.

For solar farm & commercial owners

Protect your investment, maximise every kilowatt

Soiling and undetected faults quietly erode returns. Our programs keep your array clean, diagnosed and producing — with the engineering muscle to fix whatever we find.

  • Recover lost yieldScheduled cleaning brings generation back from one of solar's biggest avoidable losses.
  • Catch faults earlyInspection and protection testing flag failing strings and relays before they become downtime.
  • One accountable partnerCleaning, inspection, electrical and civil works under one roof — proven for Glen Eira & Braeside councils.

Why maintenance pays

Soiling can quietly erode generation

Dust, pollen and bird droppings are among the largest avoidable losses in solar. On exposed or agricultural sites, neglected panels can lose a significant share of their output — scheduled cleaning brings it back.

*Illustrative industry estimate; actual losses and recovery vary by site, climate and schedule.
