Service Overview
Power Transmission
Power Tech Infra delivers end-to-end EPC and O&M solutions for Extra High Voltage (EHV) transmission systems — engineered for long-distance power transfer, maximum efficiency, and uncompromising safety. From initial survey and design to energization and long-term maintenance, we bring single-point accountability to every transmission project we undertake.
Our teams have executed projects across 33 kV to 400 kV voltage levels, working with State Transmission Utilities (STUs), DISCOMs, and private developers across Northern India. Every project is delivered on schedule, within budget, and to the highest standards of quality and safety.
