NTPC’s electricity sales volume increased by around 3 per cent year-on-year, while revenue also grew by about 3 per cent during the reporting quarter. The New Delhi-headquartered company added 196 MW of generation capacity during the quarter. However, its net capacity addition on a year-on-year basis was lower after the permanent closure of its 440 MW coal-fired power plant in September last year. Higher power demand also led to improved utilisation of NTPC’s thermal fleet. Coal and natural gas together account for more than 80 per cent of NTPC’s installed generation capacity, including joint ventures.
