Make in India | Gas-Insulated Substation

Alstom T&D India (globally known as Alstom Grid), is a market leader in the Indian power transmission sector. It has over 100 years of expertise in building the transmission infrastructure for the country. Alstom has a strong portfolio of products, solutions and services, comprising the entire range of transmission equipment up to Extra and Ultra High Voltages (765 kV and beyond) including air-insulated switchgear (AIS) and locally manufactured power transformers and gas-insulated switchgear (GIS).

It also provides power electronics solutions (HVDC, FACTS) to create super highways and offers highly advanced power management Smart Grid solutions for transmission and distribution including renewable energies integration. With around 3,500 employees and eight world class manufacturing units, Alstom T&D India is future ready to support the rapidly evolving transmission sector in India.
Alstom T&D India has recently got the contract worth INR 2266 million by Power Grid Corporation of India Ltd to supply two Gas-Insulated Substations (GIS). The two substations will be located at Betul in Madhya Pradesh and Navsari in Gujarat. Both substations will be completely manufactured in India, making this Power Grid´s first ´Make in India´ 400 kV GIS.

The first 400/220 kV GIS substation constructed at Betul will transmit power generated from the Mouda Super Thermal Power Plant ´ II. The second installation at Navsari, will carry power generated at the Kakrapar Atomic Power Station. Both substations will feed power to the national grid.
The contract scope includes design, engineering, manu­fac­turing, installation and commissioning of the GIS at Betul including supply and erection of two 400/220/33 kV, 315 MVA auto transformers. The Navsari substation, which curre­n­tly has eleven GIS bays, will be extended to include two additional bays. All equipment will be manufactured and supplied from Alstom T&D India´s manufacturing facilities in India.
GIS is gaining popularity as the preferred technology in India. It is compact and encapsulated, ideal for use in restricted areas. It is also suitable to be used in locations with severe weather conditions (high temperatures, altitudes, near the sea) and industrial environments (toxic areas or corrosive environments). The footprint of a typical GIS is generally 10 times smaller than an Air-Insulated Substation (AIS). As land becomes scarce in India, GIS has become a more commercially viable solution.

Rathin Basu, Managing Director, Alstom T&D India
had said, ´Since building the first local GIS manufacturing plant at Chennai in 2009, we have supplied over 300 bays, the largest number of GIS equipment made in India, to Indian customers. It is good to see Power Grid adopting the ´Make in India´ programme, awarding its first made in India GIS order to Alstom.´
