PTCL was incorporated on December 19, 2012. PTCL entered into a TSA on May 12, 2014. The PTCL project was awarded by the Ministry of Power to TEECL and TPGCL through a letter of intent dated September 8, 2013 for a 35-year period from the scheduled commercial operation date of the PTCL project, on a BOOM basis. In August, 2018, we completed the acquisition of 74% of the equity shares of PTCL from TEECL and TPGCL. As a result, we now own PTCL’s one substation having 1,000 MVA of transformation capacity.

PTCL constitutes a key component in strengthening the power transmission system in the state of Punjab. PTCL operates one 400 kV D/C line from Patiala to Kaithal in Punjab and has a 1000 MVA, 400/220 kV substation at Patran and 14 kV line bays. The Patiala – Kaithal 400 kV D/C transmission line was commissioned in June 2016.
