Phase IFoundation

Background

Overview

Crucial for India's energy security, integrating renewable energy into the national grid, reducing transmission and distribution losses, supporting economic growth, and achieving climate change mitigation targets.

India's rapidly growing energy demand, driven by industrialization and the expansion of renewable energy sources, necessitates continuous modernization and expansion of its power transmission and distribution infrastructure to ensure efficient and reliable electricity supply. This involves adopting advanced technologies like high-capacity conductors and high-voltage transmission lines to minimize losses and enhance power density.

Facts & tables

Key facts

Conductor Capacity

HTLS conductors carry about four times the load of conventional ones without replacing transmission towers.

High Voltage Lines

Importance of 400 kV and 765 kV lines increasing for enhanced power density and reduced losses.

Market Growth

Conductor market size expected to reach ₹23,000-₹25,000 crore by FY30.

Technology Adoption

Indian firms are forming tech tie-ups (e.g., Laser Power & Infra Ltd with TS Conductor Corp.) for local production of advanced conductors.
