State-owned power transmission major, Power Grid Corp of India Ltd (POWERGRID) has sought co-operation from all stakeholders for completion of the 1000 MVA Rajarhat 400/220kV substation in West Bengal considering that it 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,” POWERGRID said in a statement today.
“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,” the official added.
This substation, which is created with a State-of-the-Art Gas Insulated Switchgear (GIS) Technology, requires about 1/4th of the land as compared to conventional substation.
GIS technology is not only safe and reliable but also 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.
