Rajarhat 400/220kV substation, being established by Power Grid Corporation of India Limited (POWERGRID) with 1000MVA capacity, is critical to supply of power in Kolkata and surrounding areas. This substation is being connected to Farakka and Purnea so that it not only receives the power from Thermal Generating Power Stations in Farakka and Sagardighi but also hydro power from North Eastern Hydro Stations.
This substation is created with a State-of-the-Art Gas Insulated Switchgear (GIS) Technology, which requires about 1/4th of the land as compared to conventional substation. GIS technology is safe, reliable and requires less maintenance. This technology is a proven technology with more than 5000 High Voltage GIS Installations world-wide already in use; including in developed countries like Japan, UK, China, Russia, USA etc. Even in India, more than 30 High Voltage GIS Installations are working as on date.
The construction works of Rajarhat 400/220 kV Substation are undergoing for the last 2-3 years and is on the verge of completion. Government of West Bengal is all along supporting POWERGRID in the early completion of this important project. Considering the advantages of the project as mentioned above, POWERGRID solicits cooperation from all stakeholders.
