POWERGRID commissions the transmission system for Rajasthan’s solar energy zone

The POWERGRID Khetri Transmission System Limited (PKTSL), a fully owned subsidiary of Power Grid Corporation of India Limited (POWERGRID), has commissioned the transmission system associated with the Rajasthan Solar Energy Zone (SEZ) Part-C. This is one of Rajasthan’s largest transmission projects set up under inter-state tariff based competitive bidding.  The project comprises a new 765 kV Sub-station at Khetri (Rajasthan), which will connect Jhatikara (Delhi) and Sikar (Rajasthan) through 765 kV and 400 kV double circuit transmission lines respectively.

In August 2021, POWERGRID floated a tender for a substation package for the expansion of the 765/400/220 kV Bhadla-II pooling substation. This was a part of the transmission system upgrading programme to evacuate electricity from 8.1 GW of solar projects (Phase II) from the solar energy zones in Rajasthan. Last year, 11 renewable energy management centres (REMCs) were commissioned which allow centralised forecasting and monitoring of renewable energy generation The REMCs have been developed by Power Grid Corporation of India Limited (Powergrid) under the central government’s flagship Green Energy Corridors (GEC) I scheme. The REMCs are equipped with artificial intelligence-based renewable energy forecasting and scheduling tools, which provide better visualisation and situational awareness to grid operators. REMCs coordinate with the respective state load despatch centres and are integrated with existing SCADA for the despatch of renewable generation.
