RSTCPL was incorporated on November 11, 2009. RSTCPL entered into a TSA on August 4, 2010 with LTTCs. The Letter of Intent (LoI) for the RSTCPL project was awarded to consortium of Patel Engineering Limited (PEL), Simplex Infrastructures Limited (SIL) and BS Limited (BSL) by the RECPDCL (erstwhile RECTCL) on December 16, 2010 for a 35-year period from the scheduled commercial operation date, on a Build, Own, Operate and Maintain (BOOM) basis. Indigrid acquired RSTCPL from the the consortium in November 2022.

RSTCPL in the GridRSTCPL is a critical project of the Inter State Transmission Scheme (ISTS) network of the country. RSTCPL consists of 765 kV single circuit transmission line of ~208 ckms between Raichur (Karnataka) and Sholapur (Maharashtra) associated with the Krishnapattnam Ultra Mega Power Thermal Project. The project enables synchronous interconnection between Southern and Western Regions of the country and is a key transmission link to strengthen the power transmission network between these regions. Additionally, it complements IndiGrid’s existing footprint with synergies with existing 765 kV network in BDTCL and upcoming Kallam transmission project.
