Electrical Commissioning

Make sure new electrical equipment works as designed before it is energized

What it is

Electrical Commissioning

We provide independent verification that electrical systems have been installed correctly and perform as specified. Our work covers review of test plans and procedures, witnessing or performing acceptance tests on switchgear, transformers, protective relays, and cabling, and a documented handover to the owner.

Typical duration: 2 to 10 weeks depending on project size and the number of systems
Industry: Energy, Utilities & Renewables

The business problem

Why clients need this

Installation errors, loose connections, and incorrect relay settings often stay hidden until equipment is under load, when failures are costly and unsafe.

01
Contractor testing may be incomplete, undocumented, or not independent of the party that installed the equipment.
02
Owners and lenders increasingly ask for independent test records before accepting a project.
03
Baseline test data is not captured, so future maintenance testing has nothing to compare against.

Our approach

How we deliver it

1
Specification & Test Plan Review
Reviewing the project requirements and the contractor's test plan against recognised acceptance testing standards such as NETA.
2
Inspection & Testing
Visual and mechanical inspection, insulation resistance, contact resistance, ratio, and protective relay tests, performed or witnessed by qualified personnel.
3
Functional & Protection Checks
Verifying control schemes, interlocks, and protective relay operation against the approved settings.
4
Punch List & Handover
Documenting deficiencies, tracking corrections to closure, and handing over a clear set of test records and baseline data.

Data & AI

How technology strengthens this service

Test results are captured as structured records, not just scanned forms, so values can be trended against baseline during later maintenance testing and flagged when they drift.

How we use AI across our work

FAQs

Common questions

How is independent commissioning different from the contractor's own testing?+

The contractor tests to prove their own work. An independent party verifies on behalf of the owner, with no stake in passing the installation.

Which standards do you test against?+

We work to the project specification and recognised standards such as NETA acceptance testing specifications, the manufacturer's instructions, and the codes adopted by the local authority.

Can you commission solar and battery storage projects?+

Yes. We cover the electrical balance of plant, including medium-voltage equipment, inverters, and protection, and coordinate with the utility interconnection requirements.
