• Consolidated operational income grew by 35% to Rs 1783.21 crore benefiting largely out of strong generation growth in both Rosa TPP as well as Butibori TPS. The aggregate generation of both Rosa TPP & Butibori TPS in Q2FY15 was up by 35% to 3101.74 million units.
  
• Marginal 90 bps expansion in operating profit margin (to 33.5%) was largely on account of lower fuel and employee cost. The cost of fuel as proportion to sales was down by 130 bps to 61.3%. Similarly the employee cost was down by 40 bps to 1.4%. While the cost of operation was up by 10 bps to 1.4%. The other expenses were higher by 70 bps to 2.5%.
  
• Other income was down by 26% to Rs 100.94 crore. The interest cost was higher by 57% to Rs 261.08 crore and depreciation was lower by 37% to Rs 132.80 crore. Thus the growth at PBT was flat at Rs 304.26 crore.
  
• The taxation for the quarter was down by 4% to Rs 51.19 crore. Thus the net profit eventually stood marginally higher (up 1%) at Rs 253.07 crore.
