Power Transmission & Distribution

Strengthening India's power grid, end to end.

High-voltage transmission lines, substations and distribution networks — connecting generation to consumption with reliability and precision.

Rayax Infra LLP is building its Transmission & Distribution vertical to support India's power grid — from high-voltage transmission lines to substations and distribution networks. As a new entrant to this sector, we are structuring our teams and processes around the technical and regulatory standards this work demands, from 66kV feeder lines to 765kV transmission corridors.

T&D projects span long, geographically dispersed corridors and require precise route engineering, RoW management and specialised tower-erection and stringing capability. We are assembling in-house line-design engineers and experienced site crews, and building working relationships with state transmission utilities and DISCOMs, so we can deliver evacuation infrastructure reliably from our very first project.

Scope of Work

End-to-end power infrastructure capabilities across transmission, substations, distribution networks and renewable grid connectivity.

Transmission Lines

  • 66kV to 765kV transmission line EPC
  • Tower erection and foundation work
  • OPGW and conductor stringing
  • Route survey, RoW clearance and line engineering
  • Tower testing, aerial patrolling and line-maintenance support

Substations

  • AIS and GIS substation construction and commissioning
  • Switchyard civil and structural works
  • Transformer installation and protection systems
  • Substation automation and SCADA integration
  • Relay panel wiring, testing and commissioning

Distribution Networks

  • HT/LT distribution line construction
  • Rural electrification and last-mile connectivity
  • Distribution transformer installation
  • Smart metering and grid-modernisation support
  • Underground cabling for urban distribution networks

Renewable Grid Connectivity

  • Grid-tie infrastructure for solar and wind plants
  • Pooling substations for renewable energy parks
  • Interconnection engineering and synchronisation support

Our project delivery process

Five stages, one accountable delivery process, from route survey and engineering to testing and energisation.

01

Route survey & engineering

Line survey, tower spotting and detailed engineering for the transmission or distribution route.

02

RoW & clearances

Right-of-way acquisition support and statutory forest/environmental clearances.

03

Foundation & tower erection

Tower foundation construction followed by structural erection to design specification.

04

Stringing & substation works

Conductor/OPGW stringing and parallel substation civil, electrical and automation works.

05

Testing & energisation

Protection-system testing, line/substation commissioning and energisation with the utility.

Standards

Technical standards & compliance

Every project in this vertical is engineered and executed in line with the following codes, standards and regulatory frameworks.

  • Central Electricity Authority (CEA) construction and safety regulations
  • IS 802 for transmission-line tower design
  • IEC/IS standards for substation equipment and switchgear
  • State transmission utility and DISCOM technical specifications
  • Grid code compliance for interconnection and synchronisation
  • Statutory RoW, forest and environmental clearance processes
