BDTCL was incorporated on September 8, 2009. BDTCL entered into a TSA dated December 7, 2010 and a TSA dated November 12, 2013 with PGCIL. The BDTCL project was awarded to IGL by the Ministry of Power on January 31, 2011 for a 35-year period from the scheduled commercial operation date of the BDTCL project, on a BOOM basis. We acquired BDTCL from the Sterlite Sponsor in May, 2017.
BDTCL facilitates the transfer of electricity from coal-fired power generation sources from the states of Odisha and Chhattisgarh to power load centers in India’s western and northern regions. As our largest power transmission power transmission project, BDTCL operates six EHV overhead transmission lines of approximately 945 ckms comprising four 765 kV single circuit lines of approximately 891 ckms and two 400 kV double circuit lines of approximately 53 ckms. The single circuit lines comprise an approximately 260 ckms line from Bhopal to Jabalpur in Madhya Pradesh, an approximately 176 ckms line from Bhopal to Indore in Madhya Pradesh, an approximately 192 ckms line from Aurangabad to Dhule in Maharashtra and an approximately 263 ckms line from Dhule (Maharashtra) to Vadodara (Gujarat). The double circuit lines consist of an approximately 36 ckms line within Dhule and an approximately 17 ckms line within Bhopal. In addition, the project includes two 3,000 MVA substations, one each in Bhopal and Dhule.
BDTCL was fully commissioned in June 2015. BDTCL was awarded a Silver Shield for the year 2013-2014 in the category of “Early Completion of Transmission Projects” by the Ministry of Power for its Dhule substation.

The average quarterly availability of BDTCL since commissioning is set forth in the following table, which is higher than the target availability of 98% under the BDTCL TSA. As of March 31, 2020, the BDTCL TSA had a remaining term of over 29 years.
*Quarterly data is calculated as an average of three months data, based on the monthly availability certificates.
*Certain data for December 2020 are based on estimates.
