Rajasthan
Largest state in the country, Diverse
geography
Desert in west, Hilly terrain in south east
Economy
Agriculture dependent on ground water
causing heavy burden on power system
Industry is based on rich mineral resources-
Mining and processing industry viz. Cement,
Marble, Zinc, Copper and Rock Phosphate.
Discovery of mineral oil in western
Rajasthan
Power supply position is satisfactory
No power-cut on industry and in Urban area
3
Rajasthan
Rajasthan is the largest state in
India
High cost of transmission STPS
Conventional generation
sources concentrated in
south/south-east, north NCR
Renewable sources in far Jaipur
west Wind and Solar
DGTPP
Load is concentrated in KTPS
urban areas of east and NCR RPS
North Eastern part lies in NCR RAPP
CTPS
where rapid industrialisation is picking up
Large section of DMIC would pass Mahi
through Rajasthan leading to
industrial growth

Rajasthan’s Transmission System
Focused attention to Transmission in
post reform era
EHV GSS EHV Line 400 kV GSS 765 kV GSS .
(220 kV & 132 kV) (ckt km)
2001 214 16,581 1 0 .
2012 409 28,365 9 2(Under Order)
Existing transmission system can handle 18000 MVA,
7605 MW peak demand already handled
7
Rajasthan’s Transmission System
Strong and robust transmission system
capable to cater present load
State grid survived even under the major system
disturbances of Northern Region
System availability is 99.8% in 2010-11
Best reactive power management in Northern Region
Efficient grid management resulting almost flat load
curve
Transmission losses within state reduced from 4.72%
in 2002-03 to 4.2% in 2011-12, even after increase
in peak demand
New Initiatives 8
Evacuation System
RVPN committed for evacuation of
power from upcoming plants
Transmission system would be ready
matching with commissioning of
Generation
Huge investment in transmission
12th plan- Rs. 12600 Cr.
2012-13- Rs. 2800 Cr.
New Initiatives 9
Evacuation System
New 765 & 400 kV system under progress/
sanctioned
Two 765 kV GSS and 440 ckt km line from Anta
to Phagi
765 kV system for the first time in state for
evacuation of three large power plants
Chhabra
Kawai
Kalisind
11 new 400 kV GSS under progress/sanctioned
Evacuation of renewable energy
Transmission system developed for 2000 MW
Further plan for evacuation of 4000 MW by
2014-15
Investment of Rs. 2900 Cr.
New Initiatives 10
Modern Technology for Urban Area

Open Access
Rajasthan is among few states which introduced
Open Access
Open Access Regulations notified by RERC in May
2004
Open Access on transmission and distribution
available to all consumers above 1 MVA capacity
Legal frame work exists
Procedures developed and published on website
Charges determined regularly by RERC
Surcharge determined as per provisions of Tariff
Policy
Reduced every year
Reached to 20% of opening value in 2010-11
Around 250 MW capacity being wheeled through
Intra state Open access
Around 100 inter state Open access transactions
in a month using state’s grid
17
Smart Grid for RE Transmission
Renewable Generation is subject to vagaries of
nature and therefore highly variable
Advance tools are required to be incorporated for
generation forecast, scheduling and reactive
power management
Transmission network to be provided with
Reliable communication system with Optical Fibre/
wideband connectivity
Intelligent meters and devices
Switchable Reactors for Reactive Power Management
Substation Automation System & SCADA
Additional features to be incorporated in the
transmission system would entail additional cost
18
Key Issues and Concerns
ROW and Land Acquisition
ROW for lines
Delays in clearances
Land acquisition for GSS
Land availability and prices in Urban area
Skilled Manpower
Paucity of contractors
Timely supplies by Manufacturers
Development of In-house skilled manpower
Rapid Capacity Addition
Transmission to meet pace with Generation Capacity
Addition
Renewable Energy
Despatch issues of in-firm power
No incentives for development of evacuation of low
CUF power, whereas generation is incentivised
