The company said its installed capacity stands at about 8,521 MW.
"Subsidiaries CGPL (Coastal Gujarat Power Ltd) and MPL (Maithon Power Ltd) have continued to contribute significantly to the increase in generation capacity, with 11,574 million units and 2,930 million units, respectively, for H1 FY14," it said.
