Subject: Electricity Generation during the month of January’12 and during the

period April’11- January’12.

HIGHLIGHTS

• The electricity generation in the country during the month of January’12 has been 73395 MU with a growth rate of 2.43% corresponding to generation of 71654 MU during the same month last year. The growth rate during January’11 was 9.65%.

• The reduced growth rate (2.43%) during the month was due to less growth rate of nuclear generation (3.47%) and negative growth rate of hydro generation (-5.07%) and negative growth rate of gas based generation (-13.92%) (excluding liquid fuel and Diesel) in comparison to corresponding month last year.

• The cumulative electricity generation during April’11 - January’12 was 727427 MU with a growth rate of 8.59 % over same period last year. During April’10-January’11 the corresponding growth rate was 5.18 %.

• The electricity generation during January’12 was 100.02% of the program. For the period April’11- January’12, it was 102.11% of the program.

• Although availability of coal for power sector continued to be critical input for thermal generation growth, the generation from coal based plants improved on account of improved supply of coal. The thermal power stations received about 36.0 MT of coal against the requirement of 39.1 MT during January’2012. It was about 92% of the total requirement of coal during the month.

• The coal stock of 39 TPS were critical (less than 7days) on 31th January’2012. Out of these 21 TPS were having coal stock of less than 4 days.

• Coal based plants in the country have achieved a growth rate of 6.27% during January’12 over same month last year. The actual generation from coal based plants exceeded its program by 1133 MU(2.18%). Cumulative generation of coal based plants during April’11-January’12 has also achieved a growth rate of 8.94% over same period last year.

• The electricity generation during the month from nuclear plants was 136.59% of the program for the month. The growth rate of nuclear generation has reduced to 3.47% as compared to 78% during January’11. The cumulative electricity generation during April’11– January’12 from nuclear plants was 126.75% of the program. The growth rate of nuclear generation was 29.31% with the corresponding period last year.

2

• Due to less inflow, the generation from Hydro Plants had a negative growth rate of 5.07% during the month of January’12 corresponding to generation during the same month last year. However, the generation from hydro power plants for the period April’11– January’12 has achieved a positive growth rate of 17.38% as compared to 8.92% achieved during the corresponding period last year.

• The PLF of thermal stations during January’12 was 76.38% in comparison to 80.17% during January’11. The reduction in PLF was due to less generation by some stations due to various forced outages, transmission evacuation problems, coal shortages, less demand etc.. The PLF% of Central sector stations during January’12 was 86.39% as compared to 90.96% last year. The PLF of state sector thermal plants and pvt sector IPP had also reduced by 1.63% and 10.76% respectively as compared to the same month last year. However, the plant load factor of Pvt Sector Utilities slightly improved from 62.88% to 63.15% in comparison of last year.

• Four Nos.(4) of coal based thermal plants station achieved PLF of more than 100% during January’12, while 30 numbers of coal/ lignite based stations achieved PLF% of more than 90%..

• Five Nos.(5) of gas based stations had achieved PLF of more than 90% during January’12.

generation due to poor/wet coal quality during the period April’11- January’12 of about 3075 MU (as per the information received so far) has been reported.

• Loss of generation due to Low system demand (including Reserve shutdown) of thermal units during the period April’11- January’12 of about 4400 MU (as per the information received so far) has been reported.

A statement indicating the thermal generating stations suffering shortfall in generation exceeding 100 MU during the period April- January’12 along with the reasons thereof is attached at Annex-I.

Availability of Coal: During the current financial year 2011-12, the anticipated gap between the requirement and availability of domestic coal was estimated around 54 MT. Out of 54 MT, 35 MT of coal was to be met through import of coal, for which all the utilities have been advised to take necessary action and rest 20 MT of coal was the requirements of power plants designed on imported coal. The status of import of coal by various utilities (as on the last day of January’12) is given in Annex-II.

The coal stock position at various thermal plants continued to remain critical. The coal stock of 39 TPS were critical ie less than 7days, on 31st January’2012. Out of these 21 TPS were having coal stock of less than 4 days. The main reasons for coal shortages are inadequate receipt of coal, huge outstanding dues , higher generation etc.

Best Performing Power Plants: During the month of January’12, 30 numbers of coal based TPS with an aggregate installed capacity of 28600 MW achieved PLF more than 90%. The list is enclosed at Annex-III. Four (4) thermal power stations mainly, KAKRAPARA (440 MW), GH TPS( 920 MW), SIPAT STPS(2320MW), Torangallu TPS (260 MW) achieved PLF more than 100 % during January’12. Among them KAKRAPARA (440 MW) had the highest PLF of 101.5%.

Gas based Generation : In view of the increased generation from hydro, nuclear and coal based plants leading to low schedules for gas based generation coupled with the problem of gas supply shortages to various gas based stations, the gas based generation had a negative growth rate of 13.92% and 4.72% during January’12 & April’11- January’12 respectively corresponding to the same period last year.

Total Loss of generation during the month December’11 and April-December’11 alone due to short supply of Gas was 1247 MU and 5108 MU respectively (reported so far).

The Liquid fuel based stations had a negative growth rate of 73.24% and 52.54% during January’12 & April’11- January’12. Average %PLF achieved by the gas /liquid fuel based plants during January’12 further reduced to merely 54.55% against PLF of 65.55% achieved during same period last year. Region-wise average PLF of gas based power plants is given in Annex- IV. Average PLF of gas plants located in the Southern Region was the lowest during January’12 at 50.65% against

8

PLF of 60.03% achieved by the gas plants located in the Southern Region during the same month last year.

Ten (10) numbers of gas based power stations having aggregate installed capacity of 2897 MW operated at PLF above 80% during the month of January’12. Among these, three power plants is under Central Sector, Four power plants are under State Sector Utilities and three power plants are under Pvt. Sector Utilities.Trombay CCPP of 180 MW capacity had achieved PLF 102.41% during the month. The details are given in Annex – V.

Nuclear Generation

During the month of January’12, generation from nuclear plants exceeded its target by 97 MU. The nuclear generation was 2903 MU against the target of 2806 MU during the month, representing an achievement of 136.59% and a growth rate of 3.47% with respect to nuclear generation during same period last year. During the month, the average PLF of all nuclear plants was 81.66% against 81.72% achieved during same period last year. PLF achieved by Kakrapara APS was above 100%. PLF achieved by Kakrapara APS, RAPS and Tarapur were 101.5%,94.33% and 90.02% respectively during January’2012.

Hydro Generation

The energy generation from the hydro electric stations (excl. import from Bhutan) during the month of January’12 was less by 0.04%. than its target The hydro generation had also a negative growth rate of 5.07%. This was due to reduced inflows during the month.

During the period April’11 to January’12, the cumulative hydro generation was 114734 MU against the target of 97547 MU registering an achievement of 117.62% with respect to the generation target. Hydro generation during this period has registered a growth of 17.38% over the same period last year. Region wise details are as follows:-
