India’s minister of state for power and officials from Power Grid Corp. of India unveiled a 1,200 kV substation at Bina, a north-central Indian town of 120,000 that is already home to several refineries and power plants.

The 1,200 kV substation is based on technology developed by Power Grid Corp. of India and will function at an ultra high voltage alternating current.

The substation would supply electricity to Guna, Indore and Gwalior, besides other metropolitan cities of India. Substations of 220, 400 and 765 kV already exist in Bina.

The project is an example of public-private partnership in which all UHV appliances have been developed by the Indian manufacturers’ consortium with the Power Grid making available adequate resources, basic systems design and specifications. The manufacturers have developed appropriate facilities for designing, manufacture and testing of various appliances.

The will help transmission over long distances from remote production centers to load centers. It would also ensure economical development of wholesale power transmission corridors in the country.
