Power capacity addition drops during January

Untitled - 70.jpgThe country could add only 480 mw of new capacity in January, only a sixth of what was targeted for the month. Unless the next two months achieve turnaround, the fourth quarter could see reversal of improvement in the pace that had gathered to 4,795 mw in the third quarter, from 2,870 mw in Q2 and 2,065 mw in Q1. The feat has lifted the total capacity commissioned during the first ten months of the current fiscal to 10,211 mw, 58 per cent of 177,48 mw planned for the period.

The net capacity addition in public utilities till January in the ongoing XI Plan period amounted to 28,873 mw, comprising 25,280 mw of thermal, 2,713 mw of hydro (renewable) and 880 mw of nuclear power. The renewable energy sources (grid-connected) including small hydro power, biomass gas/power and wind energy, etc whose estimates are sourced from Ministry of Renewable Energy (MNRE) contributed 9,026 mw. The addition to stock of public utilities has already exceeded 21,151 mw added during the X Plan period and 18,524 mw in the IX Plan. Renewable energy, a star performer, has in fact already surpassed the climb in earlier plan by 50 per cent.

The total stock of installed generating capacity at the end of January worked out to 170,229 mw; of which thermal power comprised 111,294 mw, large hydro power 37,637 mw, nuclear 4,780 mw and RES 16,787 mw. Grid connected captive generating capacity contributed another 19,509 mw. The State government-owned power plants accounted for 48 per cent total installed capacity, followed by 31 per cent in Central government owned plants and 21 per cent in private sector plants. In RES, private sector accounted for 83 per cent of total capacity of 16,787 mw, while nuclear power is exclusively with Central government.

Power transmission: The capacity addition of 28,031 ckm (circuit km) to 400kV transmission lines and 18,633 ckm to 220kV transmission lines till January in the ongoing XI Plan has already exceeded their respective additions during the 10th Plan. Likewise, additions in terms of transformation capacity in 400kV and 220kV substations have also surpassed their X Plan augmentations.

Power deficit: The average deficit worked out provisionally to 7.6 per cent in January, lower compared to 8.2 per cent in December, which had reversed the declining trend of past two months that had brought down the deficit to 6.5 per cent in November. Deficit during the first ten months of the current fiscal worked out to 8.6 per cent, inferior compared to 9.9 per cent in the corresponding period a year ago, and 11 per cent in this period two years back. In fact, after running higher till August, relative to year ago levels, power deficit has tended to be less severe than year-ago levels in the subsequent five months. Cumulative peak demand level deficit worked out to 11.1 per cent, against 12.6 per cent in the similar period last year and 13.8 per cent two years back. Lower power shortage could be reflective of a slowing economy as growth in generation during the period was lower than that a year ago.

Among the regions, Western region faced 13.4 per cent average deficit, much higher than the average for the country. Northern region faced 8.3 per cent deficit. Southern region and the eastern region faced 5.2 per cent and 4.4 per cent deficit, respectively.
