DPSC
Limited SYSTEM consists mainly of 2
generating stations one each at Chinakuri and Dishergarh and two 11KV
networks one covering Dishergarh and Chinakuri areas and the other
covering Seebpore, Luchipur and Satgram areas. The present generating
capacity of Chinakuri Power Station (CPS) is 30MW . Generating Capacity
of Dishergarh Power Station is about 12MW .The Generating Stations
are basically providing survival power requirement to our consumers.
These generating stations supply 42MW power out of our total requirement
of 122 MW. The balance power is mainly drawn from DVC's system at
four intake points viz., Dishergarh, Satgram, Seebpore and Luchipur.
The Power from DVC system is taken at 33 KV and it is then stepped
down to 11 KV for distribution for our consumers. The Company's generation
meets about 32% of its system demand, while the balance 68% is sourced
from DVC and WBSEB.The system details are as follows :

Power Distribution: Network System
The present peak load of the company
is 122 MW and Power is supplied predominantly at 11kv.Around 32%
of the load is met from own generation , while the balance is met
through imports of power from DVC and WBSEB.Imports of power take
place from DVC at four points spread over its licensed area and
from WBSEB at one point.The Company supplies power to WBSEB consumer
at 18 different points in its licensed area spread over Asansol/Raniganj
Coal & Industrial belts.
Power Distribution: Sales
Growth Due to
- Maintaining
& supplying good quality power to its consumers.
- Development
of New Industries in the licensed area.
- Increase
in sales of the Energy.
- Reduce
Auxiliary and Coal Consumptions in the power stations.
- Reduce
T&D Losses.
- Maximize
generation from own low-cost generating station (CPS).

System Loss
DPSC Limited is maintaining a testing laboratory
with sizeable work force to improve metering system and to arrest
commercial losses as well.
Major activities undertaken for the last two / three years:
- Introduction
of microprocessor based State-of the -Art static meter in
consumer premises.
- Introduction
of new tamper proof metering box / cubicle to reduce attempt
of theft.
- Improvement
of meter sealing system.
- Phasing
out existing meters by good quality meters.
- Increasing
vigilance for supervision and checking of meter readings.
- System
study of the consumers' point including load pattern and
period of operation.
- Computerized
billing and follow up action.
- Augmentation
of overloaded overhead / underground lines.
- Improvement
of system power factor by way of installing reactive power
compensation units.
- Shifting
of Distribution / Power Receiving Points at load centres.
- Installation
of 132 kV / 33 kV capacitors to maintain quality of power
to consumers
|
The total load of the system is 122
MW. Due to restriction on constructing 33 KV Transmission network
due to DVC Act, the distribution had to be done at 11KV.In spite of
the above limitation, the T&D loss is in the range of 6% which
is one of the lowest in the country.
Consumer Profile
Eastern Coalfields Limited (ECL)
is the single largest consumer of the Company constituting 60% of
the Load of the Company. About 25% of the Load is that of WBSEB who
buy power from DPS at 11 KV. Balance 15% of the load absorbed by other
industries and by essential services like Hospitals, Nursing Homes,
Pumping Stations, Railways, TV & Radio Stations Etc. |
