High Voltage Construction & Maintenance

Building and maintaining HV, solar and renewable infrastructure to the highest safety standard.

From new private HV networks to solar farm maintenance, our high voltage team keeps critical infrastructure running.

Maintaining electrical infrastructure is vital for safety, reliability and efficiency — particularly for solar and renewable energy installations and private high-voltage (HV) networks. Regular maintenance extends the lifespan of infrastructure, prevents costly breakdowns, and keeps systems compliant with Queensland’s strict electrical safety regulations.

Our HV construction teams design and build new private networks from the ground up — subdivision infrastructure, pad mount transformers, ring main units and switching arrangements — while our maintenance crews carry out the inspections, servicing and fault response that keep existing HV assets, solar farms and battery storage systems performing to specification.

Whether the job is a greenfield HV network for a new industrial estate or a scheduled maintenance visit to an operating solar farm, our approach is the same: documented safe work procedures, qualified HV-endorsed electricians, and thorough compliance testing and reporting at every stage.

Our process

01

Scope & Site Assessment

HV network requirements, load profiles and site conditions are assessed to develop a safe, compliant scope of works.

02

Design & Approvals

Network design and switching arrangements are developed and submitted for the relevant regulatory and network approvals.

03

Construction & Installation

HV-endorsed electricians carry out construction, installation and commissioning under strict isolation and safety procedures.

04

Testing & Compliance

Full compliance testing, load testing and documentation are completed prior to energisation and handover.

05

Ongoing Maintenance

Scheduled inspections, servicing and fault response keep HV, solar and battery storage assets performing safely long-term.
