NTPC formed another joint venture company with SAIL on in March 2002 in the name of Bhilai Electric Supply Company Ltd. (BESCL). BESCL took over a captive power plant (comprising 2x 30MW generators and one 14MW back-power turbo generator) located at the Bhilai Steel Plant from SAIL. Effective 11 September 2006, BESCL became part of NSPCL.
Since 2006, NSPCL has provided all power required by the Bhilai, Durgapur and Rourkela steel plants. To meet growing demands, NSPCL commissioned an expansion project at Bhilai comprising two 250MW generators during 2008–2009, and brought the units online in 2009–2010. Additional growth to generate an additional 1750MW is anticipated at other SAIL facilities.
