Green Power for Green Delhi
Be it plantation, no-industry zones or 100% Commercial Vehicles
on CNG, Delhi’s obsession with Green is quite evident. No wonder,
Delhi has also engineered one of the greenest power generation
and transmission systems. Clean and green production processes
of Pragati Power Corporation Ltd. (PPCL) and minimum loss
transmission systems of Delhi Transco Ltd. are at the heart of
Delhi’s Green Power Vision.

Chief Minister,
Delhi
Power Foundation:
Pragati Power Corporation
Ltd. (PPCL) was started with a
mission to play a pivotal role in
the development of NCT and
uplifting of the living standards
of the citizens. The company
is committed to provide clean
& green energy with special
emphasis on sustainable
development by adopting
energy efficient technology for
power generation. The existing
and forth-coming projects are
the mirrors of self imposed
corporate standards for clean
& energy efficient technology products &
services. Delhi Transco Ltd was formed
in 2002 following the unbundling of the
erstwhile Delhi Vidyut Board under the
Delhi Electricity Reforms Act 2000.
DTL has been responsible for establishing,
upgrading, operating and maintaining the
EHV (Extra High Voltage) network in and
around Delhi.
Delhi Transco Limited:
A noteworthy achievement of DTL has
been the company’s transmission loss
reduction. Transmission loss level has
been reduced from 3.84 per cent in
2002-03 to 1.38 per cent in 2009-10,
which is the lowest transmission loss
level in the country. For improvement of
operational efficiency, regular monitoring
and maintenance of equipment is carried
out through patrolling of transmission
lines and hotline washing of insulator
strings. Further the work of replacing
the existing 400 KV insulators with
polymer insulators is being carried out.
To ensure adequate and efficient
power supply for the citizens of Delhi,
DTL has been continuously upgrading
its transmission capacity and adding
transmission line to its system. The modern
technologies are being implemented in
DTL by way of constructing GIS substations
at Ridge Valley, Indira Gandhi
International Airport (DIAL) as well as
other places.
DTL is also in the process of laying 220 KV
cables by employing cable link techniques
and would be the largest network of its
kind going to be established in India. Out
of all the projects initiated by DTL, the
work of two 220 KV GIS sub-stations has
been completed and will be synchronized
by the end of September 2010 after
testing. The work for 2 sub-stations of
400 KV and 5 sub-stations of 220 KV is
in full swing.
Powered by IT:
Following the e-Governance initiatives of
GNCTD and to enhance its efficiency and
productivity, DTL has initiated several IT
based projects. For constant access to realtime
data of the entire network, the utility
has implemented Supervisory Control and
Data Acquisition (SCADA) systems.
DTL has also carried out system studies,
adopting state-of-the-art-software.
Enterprise Resource Planning Software,
is being implemented which will offer an
integrated software solution to all the
functions of the organization. With ERP
software DTL will standardize business
processes and facilitate best practices
by creating more efficient systems
and concentrating its efforts towards
maximizing profits.
Power Finance:
DTL has achieved a commendable financial
turnaround after a three-year financial
engineering process. It has posted profits
in each of the past 4 years.
In 2008-09 DTL profits, after tax stood at
Rs. 634.9 million, an impressive 22.84%
increase over the Rs. 516.9 million

Plans.
All efforts have been made to run various
systems as per the designed parameters to
conserve energy.
1.Overhauling of the unit was carried out
as per the manufacture’s direction to run
the machine optimally.
2.2. 220 KV CVT’s were installed in
each phase of all the three generators to
improve the accuracy of metering system
for the sale of energy.
3.The Auxiliary consumption of the Pragati
Power Station- 1 in the year 2009-10 was
2.85% and achieved the Aux. consumption
target 3%.
