2.1 POWER GENERATION
The actual energy generation in 1993-94 was
323531 MUs consisting of 247757 MUs
Thermal, 5399 MUs Nuclear and 70375 MUs
Hydro, as against the target of 316700 MUs.
The generation during 1993-94 was 7.4%
more as compared to 1992-93. Thermal
generation registered an increase of 10.3%
over 1992-93. The generation programme for
1994-95 is 352000 MUs consisting of 274700
MUs Thermal, 8300 MUs Nuclear and 69000
MUs Hydro. The generation programme
envisages an increase of about 8.9% over the
actual generation during 1993-94. Energy
generation during the period April to Dec.,
1994 as compared to the programme and to
the corresponding period of the previous years

2.2 PLANT LOAD FACTOR (PLF) OF
THERMAL STATIONS
(i) Thermal capacity, at present constitutes about
70% of the total installed capacity, in the
country, and contributes about 76% of the total
power generation. At the beginning of the
6th Five Year Plan, the performance of the
5
thermal power stations was unsatisfactory with
the All India average plant load factor of 44.3%
only. To improve their performance, a number
of measures were taken to achieve the optimum
utilisation of the existing thermal units. At the
beginning of 7th Five Year Plan i.e. 1985-86, the
all India average PLF improved to 52.4% and
further increased to 56.5% in 1987-88 which
was the highest achieved in any year. During
1993-94 the PLF was 61.0% which is the highest
ever achieved. During the period April, 1994 to
Dec., 1994 the All India PLF has been 57.5%.
During this period the following State Electricity
Boards/Corporations achieved PLF higher than
the All India average of 57.5%.

In the State Sector, Kota Thermal Power
Station of RSEB, Khaperkheda II of MSEB,
Vijayawada of APSEB and Mettur of TNEB
achieved highest PLF of more than 70%
during this period. In the private sector, CESC
achieved the highest Plant Load Factor of
76.4% during the same period. In the Central
Sector, Singrauli (76.0%) Korba (75.3 %) and
Vindhyachal (77.5%) Ramagundam (73.3%)
and Farakka (75.2%) Super Thermal Power
Stations of NTPC achieved the highest PLF
during the same period.
