Substation Construction

We build new 33/11 kV substations and extend or upgrade existing ones for state power utilities, taking the work from foundations to commissioning.

Substation Construction

Overview

A substation has to be right in every detail: layout, foundations, equipment erection, protection wiring and earthing. Our teams handle the civil and electrical scope together, so the utility deals with one contractor from site preparation to energisation.

Every substation is built to the utility's approved drawings and specifications, inspected at each stage and tested before it is handed over.

Scope of work

  • Site survey, levelling and layout marking
  • Equipment and structure foundations
  • Control room building, cable trenches and fencing
  • Erection of structures, bus bars and gantries
  • Erection of power transformers, breakers, isolators, CTs, PTs and lightning arresters
  • Control and relay panel installation and wiring
  • Earth mat laying and earthing of all equipment
  • Pre-commissioning tests, energisation and handover

How we deliver

Survey & plan

Joint site survey with the utility, then drawings, materials and schedule for approval.

Execute safely

Skilled crews carry out the works under safety supervision and stage-wise quality checks.

Test & hand over

Every installation is tested, inspected and commissioned before formal handover.

Common questions

Do you take up both civil and electrical works?
Yes. We handle the civil works and the electrical erection together, so the substation is delivered by a single contractor.
Can you extend an existing substation?
Yes. We take up bay extensions and capacity upgrades at live substations, planned around the utility's shutdown schedule.
