PGCIL commissions Khavda Phase IV Part E4 transmission project

Power Grid Corporation of India Limited (PGCIL) has commissioned the “Transmission System for Evacuation of Power from potential RE zone in Khavda Area of Gujarat under Phase IV (7 GW) – Part E4” with effect from June 21, 2026.

The company received the Declaration of Commercial Operation (DOCO) dated July 13, 2026, through email on July 14, 2026. 

Project scope

The project has been implemented under the Regulated Tariff Mechanism (RTM) at an estimated cost of Rs 235 crore, with a scheduled implementation period of 24 months from the date of allocation.

Part E4 primarily involved augmentation of transformation capacity at the Padghe (PG) Gas Insulated Substation (GIS). As part of the project, PGCIL commissioned one 1,500 MVA, 765/400 kV interconnecting transformer (ICT), taking the number of such transformers at the substation to four.

The scope also included the commissioning of two 765 kV bays and two 400 kV bays, with one bay at each voltage level provided for completion of the substation’s diameter arrangement under the one-and-a-half breaker configuration.

In addition, the project involved the installation of approximately 510 metres of 765 kV GIS duct and around 500 metres of 400 kV GIS duct, along with associated support structures.

Renewable integration

The project forms part of the broader Khavda Phase IV transmission scheme, which has been planned to facilitate evacuation of up to 7 GW of renewable energy from the Khavda renewable energy zone in Gujarat.

The augmentation of transformation capacity at Padghe is expected to strengthen the transmission corridor for integrating renewable power from western India into the national grid.

Khavda has emerged as one of India’s largest renewable energy development zones and is expected to contribute significantly to the country’s solar and wind energy capacity additions over the coming years.
