Alstom T&D India has been awarded two contracts with a total value of INR 2983 million (€38 million) to supply two 400/220/66 kV gas-insulated substations (GIS) at Wangtoo and Gumma in Himachal Pradesh. The projects respectively received from Larsen & Toubro (L&T) and HP Power Transmission Corporation Limited (HPPTCL), respectively, aim to improve the power transmission capacity of HPPTCL for the transport of electricity generated by hydropower sources across the state.
The scope of the Wangtoo project, worth approximately INR 1550 million (€18 million), covers the design, engineering, manufacture, supply, testing, and commissioning of 400 kV, 220 kV and 66 kV gas-insulated switchgear, power transformers, instrument transformers and substation automation system.
The Gumma project, worth INR 1433 million (€20 million), includes design, engineering, manufacture, supply, erection, testing, commissioning and covers civil works of 400 kV and 220 kV GIS substation on a turnkey basis. All key equipment for both the projects will be produced by Alstom’s state-of-the-art manufacturing facilities across India.
Rathin Basu, Managing Director, Alstom T&D India says, “With these dual contract wins for HPPTCL, Alstom is pleased to earn the confidence of its customer for the provision of advanced GIS solutions at the Wangtoo and Gumma substations. Alstom is the leader in India’s GIS activity and has so far supplied over 500 GIS bays in India, covering a range of voltages from 66kV to 400kV. Over 50% of the supplied solutions are produced in India.”
Alstom has been the pioneer in localizing GIS manufacturing activity in India since 2009 at its facility in Padappai near Chennai. GIS is the preferred technology for hydropower plants and coastal areas: its compact and enclosed design makes it ideal for smaller footprint and low maintenance application. It is well-adapted for areas where space is scarce, such as cities and regions where cost of land is high.
Himachal Pradesh is one of the few states in India with almost 100% electrification. The Wangtoo and Gumma projects will provide additional hydropower. Once complete, this additional power provided by the Wangtoo & Gumma projects will serve the state’s growing demand, and the national grid through interstate power transmission.
 HP Power Transmission Corporation Limited (HPPTCL) was established on 27, August, 2008 to work on the transmission Master Plan of the Himachal Pradesh State
