Torrent Power Substation Infra
The Torrent Power Substation Infrastructure project involved the engineering, procurement, civil construction, and commissioning of a mission-critical 132kV/33kV high-voltage electrical substation and automated switchyard designed to power expanding heavy manufacturing zones across Western India.
Valoris Turnkey Solutions orchestrated the complete lifecycle from switchyard earthmat design and high-voltage transformer foundations to Gas-Insulated Switchgear (GIS) installations, lightning protection grids, and centralized IEC-61850 compliant SCADA automation dashboards.
Operating in proximity to live grid infrastructure, our electrical engineering desk implemented zero-incident safety protocols, completed rigorous CEIG testing ahead of deadlines, and synchronized the substation seamlessly with the regional state electrical transmission corporation.
Engineering and commissioning a high-voltage 132kV transmission switchyard in a high-density industrial corridor with zero disruption to adjoining municipal power feeds and stringent grid code compliance.
Implemented modular Gas-Insulated Switchgear (GIS) technology to minimize physical footprint by 60%, deployed automated relay protection schemes, and pre-commissioned SCADA telemetry in parallel with civil construction.
