Factor (PLF) of the thermal power stations. The average plant availability has
improved up to a level of 78.11 per cent in 2004-05. HPGCL has reduced coal
consumption and secondary oil consumption by about 8 per cent and 6.7 per cent
respectively. Thermal power plants of HPGCL have attained improvement in respect
of auxiliary consumption, which has been consistently coming down since 2000-01.
TRANSMISSION
Positive outcome
A total of around Rs 1,453 crore had been spent on network augmentation and
expansion of the transmission system since 1998-99, resulting in an increase in the
number of 220 kV sub-stations by around 50 per cent and 56 per cent in 132 kV substations
after restructuring. HPVNL has set an optimistic investment plan of about Rs
684 crore for 2006-07 and Rs 5,194 crore for the Eleventh Plan. The sources of funds
to be deployed in the investment plan are, however, subject to prudence check and
approval by HERC.
HVPNL’s achievement of 98 to 99 per cent availability of most of its transmission
network in the State is commendable. There has been a reduction in the overall losses
in the transmission system in the State. The inter-State losses are around 1.45 per cent;
even the intra-State losses have come down to 3-4 per cent. There was a significant
saving in outages to the extent of about 466 hrs on 220 kV lines on account of hotline
maintenance carried out by the Utility staff. Around 9,000 hrs of planned maintenance
was carried out, which enhanced the reliability of power supply in the State.
Key Concerns
It is desirable that the concerned State Utilities conduct requisite load flow studies to
further improve the reliability and quality of power supply in the network. The
network augmentation should be based on reliability principles and studies. This
would ensure that the power system expansion is in line with the future demands.
While State Load Despatch Centre (SLDC) has been set up as a separate entity
presently working under the STU, however Area Load Despatch Centres (ALDCs) for
the DISCOMs have not been established. Also, the interface metering consequent to
network expansion has also not been completed. This is likely to lead to delay in the
introduction of intra-State availability based tariff (ABT).
