annual report 1994-95 ministry of power

& Distribution losses for the country as a whole
reduced from 22.83% during 1991-92 to 21.80%
during 1992-93 thereby achieving a reduction of
1.03%.
(ii) Under the Incentive Scheme, launched by the
Government of India in the year 1987-88, the
SEBs/EDs and their Distribution Divisions/
cities/towns are awarded with shields on the
basis of their performance in reduction of
Transmission & Distribution losses. Cash
awards are given to Distribution Division/
cities/towns of the Power Utilities which
achieve a prescribed minimum reduction in
T&D Losses. Individuals as-well-as institutions
& organisations also qualify for grant of
incentives for developing scientific devices or
presenting new ideas which prove to be effective
in saving energy by optimal utilisation of T&D
system or better quality of power supply or
improved efficiency of electrical appliances.
(iii) For the year 1991-92, Karnataka Electricity
Board, Tamil Nadu Electricity Board,
Electricity Department of Pondicherry and
four best performing Distribution Divisions/
cities/towns viz. Baroda City Circle (GEB),
Tenali (APSEB), Indore city (MPEB),
Pondicherry region (Electricity Department,
Pondicherry) have been recommended for
award of shields. Cash award of Rs. 3 lakhs
to three Distribution Divisions of GEB.
Rs. 1.23 lakhs to two Distribution Division of
MPEB. Rs. 5.27 lakhs to seven Distribution
Divisions of APSEB and Rs. 2 lakhs to
Pondicherry region of Electricity Department
of Pondicherry have also been recommended.
4.4 INTEGRATED OPERATION OF GRIDS
(i) The Regional Power Grids in the Northern,
Western, Southern and Eastern Regions
facilitate flow of power from surplus areas to
deficit areas and assist in the optimum
utilisation of the power availability in the
country.

4.4.1 National Power Grid
(i) The Union Cabinet in 1980 approved in principle
the establishment of a Centrally owned and
operated National Power Grid. The National
Power Grid would eventually comprise strong
Regional networks with suitable synchronous
(HVDC) links between the regions. Already
19,747 Ckt.Kms of 400 kv lines and 6,283 Ckt.
Kms of lines at 220kv level have been
constructed in the Central Sector, upto November
1994. An inter-regional link (Vindhyachal 2x250
MW HVDC back-toback) connecting Western
and Northern Regions is also in operation. These
as well as other AC links between regions form
the important components of the National Power
Grid today.
(ii) In October, 1989 Government of India
established the Power Grid Corporation of India
Limited (POWERGRID) to further accelerate
the development of the National Power Grid.
The POWERGRID have already taken over
most of the existing Central Sector transmission
systems. The POWERGRID also propose to
take up schemes for further strengthening of the
Regional Power Grids and establish HVDC
back-to-back inter-regional links.
(iii) Although the Regional Grids have already
been inter-connected, paving way for
formation of a National Grid, further
strengthening of intra-regional and interregional
tie lines would be needed to enable
increased power exchanges and achieve
improved economy and reliability. This is a
continuous process and projects are being
taken up during each plan period depending
upon the requirements of inter-regional
power exchanges and the funds availability.
4.4.2 National HVDC Project
(i) The first stage of National HVDC project
converting existing 220KV DC-AC line between
Lower Sileru (A.P.) and Barsoor
