India’s inter-regional transmission capacity is planned to reach 143 gigawatts (GW) by 2027 to strengthen the national power grid.
The capacity was about 120 GW in 2025 and will be expanded to 143 GW (2027) and 168 GW (2032) to ensure smooth electricity flow across regions.
The expansion is part of the National Electricity Plan (NEP) to improve reliability and integrate renewable energy sources.
India’s peak electricity demand is projected to reach around 388 GW by 2032, requiring a strong transmission network.
The plan also includes expansion of transmission lines to 6.48 lakh circuit kilometres (ckm) and transformation capacity to 2,345 GVA (Giga Volt Ampere), improving overall grid capacity and efficiency.
