MTL was incorporated on August 14, 2014. MTL entered into a TSA on June 10, 2015. The MTL project was awarded by the Ministry of Power on July 21, 2015 for a 35-year period from the scheduled commercial operation date of the MTL project, on a BOOM basis. We acquired 49% of MTL from the Sterlite Sponsor in February 2018. MTL constitutes a key component in enabling the southern region of India to draw more power from the rest of the grid and seeks to address the issue of power stability in the state of Telangana. This improved grid connectivity is expected to facilitate power procurement from the ISTS network to meet electricity demands in south India.
MTL operates two EHV overhead transmission lines with a total circuit length of approximately 477 ckms in the state of Telangana, comprising one 400kV D/C line of approximately 197 ckms from Maheshwaram to Mehboob Nagar in Telangana and one 400kV D/C line of approximately 279 ckms from Nizamabad to Yeddumailaram in Telangana. MTL also has four 400kV line bays. The Maheshwaram – Mehboob Nagar 400 kV D/C transmission line was commissioned on December 14, 2017, while the Nizamabad – Yeddumailaram 400 kV D/C transmission line was commissioned on October 14, 2017. The project was fully commissioned on December 14, 2017.
Details of MTL’s transmission lines and line bays are set forth as follows:
|Transmission line / Sub-Station||Route Length (ckms)||Specifications||Commission Date||Expiry of TSA Term||Contribution to Total Tariff|
