Sterlite Power brings first 400 kV Gas-Insulated Substation (GIS) in Goa

Sterlite Power has successfully completed the Goa-Tamnar Transmission Project, implemented through its Special Purpose Vehicle, Goa-Tamnar Transmission Project Limited (GTTPL).

Sterlite Power, a leading global power products and solutions business, has successfully completed the Goa-Tamnar Transmission Project, implemented through its Special Purpose Vehicle, Goa-Tamnar Transmission Project Limited (GTTPL). The project strengthens Goa’s power infrastructure with four vital elements, three of which have now been successfully commissioned and the final component, the Xeldem-Narendra transmission line, is set to commence soon. This project brings Goa’s first 400 kV Gas-Insulated Substation (GIS) at Dharbandora live, providing a high-quality power supply that reaches South Goa at 400 kV for the first time.

Commenting on the development, Arun Sharma, CEO, Infrastructure Business, Sterlite Power said, “This project is a crucial step forward in strengthening Goa’s power infrastructure. By addressing key gaps and bringing advanced technology like the GIS substation to the state, we are ensuring a more stable and reliable power supply for the people and businesses of Goa, which will further boost tourism and add to the economy. It’s a proud moment for our team, and a reminder of what’s possible when vision and collaboration come together.”

The new infrastructure will stabilize power delivery, minimising outages, especially in South Goa, and will enable high-quality power supply across industrial, commercial, and residential segments. The enhanced transmission capacity will also provide a direct feed from the new Dharbandora substation to South Goa, reducing the load on existing substations and making the network more resilient against fluctuations. This is particularly crucial for Goa’s economic hubs, including its tourism and hospitality sectors, which have long been burdened by reliance on costly diesel generators to manage frequent power outages.
