Abstract—SmartGrids were introduced to make the grid oper-
ation smarter and intelligent. SmartGrid operations, upon appro-
priate deployment can open up new avenues and opportunities
with significant financial implications. SmartGrids can continue
towards enhancement of power market. The current status of the
power market as well as initiations of SmartGrids in India are
studied to scrutinize the potential power market enhancement
with the advent of SmartGrids. This paper presents various
SmartGrid initiatives and implications in the context of power
market evolution in India.

HE Indian power sector is expanding at a fast pace. India
has a power sector characterized by deficient generation
and high distribution losses. The first power exchange of India
was introduced in June 2008. SmartGrid activity has been re-
ported in some distribution pockets mostly by private players.
Many utilities in power sector have now SmartGrid activity
with high priority in their research and development agenda.
The market functions which are likely to get affected due to
SmartGrids are discussed. The priority of these functions de-
pends on several factors such as policies, regulation, efficiency
of the markets, costs and benefits associated with the functions,
and service providers and traders etc. Though there are many
barriers for these new developments, the Government of India
has some policies to support SmartGrids in the distribution
sector. Some of the key issues emerging for implementation of
SmartGrid include secure communication, standard protocols,
data management and an efficient architecture which can
facilitate data exchange. These issues are discussed in the
Indian context.
SmartGrids can bring in new market products also. Smart-
Grids can convert data into useful information and have the
capability to take local decisions in distributed manner, and
can also offer self healing. These features can be used for
market enhancement as decision support. There is growing
demand for “quality power” in power market. SmartGrids can
offer effective solution to this demand. Some details on these
aspects are covered. Finally, a comprehensive road map on the
role of SmartGrids for enhancement of power market in India
is reported.
The organization of the paper is as follows: In section II,
an overview of Indian power market and its current operation
structure is covered. Recently released market products are

various initiatives in India. Section V points towards some
of the required focus areas and needs for an efficient power
market with the advent of SmartGrids in India. Section VI

II. OVERVIEW OF I NDIAN POWER MARKET
In India, electricity reforms started with the re-evaluation
of Electricity Supply Act, 1948 and the Indian Electric-
ity Act, 1910 which led to the Electricity Act, 2003. The
Electricity Act, 2003 has been brought about to facilitate
private sector participation and to help cash strapped state
electricity boards to meet electricity demand. The Electricity
Act, 2003 envisages competition in electricity market, pro-
tection of consumers interests and provision of power for
all. The act recommends the provision for national electric-
ity policy, rural electrification, open access in transmission,
phased open access in distribution, mandatory state electricity
regulatory commissions (SERCs), license free generation and
distribution, power trading, mandatory metering, and stringent
penalties for theft of electricity. One more welcome step that
the Indian electricity market has taken is the implementation
of availability based tariff (ABT) which brought about the
effective day-ahead scheduling and frequency sensitive charges
for the deviation from the schedule for efficient real-time
balancing and grid discipline.
The fixed and variable costs of electricity production are
treated separately in the ABT. Fixed cost, known as capacity
charge, is associated with plant availability and its capacity
to deliver MWs on day-to-day basis. Generating plant is paid
the capacity charge according to its average availability over
a year. Variable charge, known as energycharge, is the charge
associated with the variable cost of energy production and the
total amount paid to the generators is based on their scheduled
energy production rather than actual production. The third
component of ABT is called unscheduled interchange (UI)
which is the payment for deviation from the schedule, and the
rate is decided according to the system frequency. Beneficia-
ries are paid for the underdrawal or charged for the overdrawal
according to the system frequency. Thus the UI mechanism
acts as a balancing market in which real-time price of the
electricity is determined by the system frequency.
To promote power trading in a free power market, central
electricity regulatory commission (CERC) approved the setting
up of Indian energy exchange (IEX) which is the first power
exchange in India, in June 2008. IEX has been modeled based
on the experience of one of the most successful international
power exchanges, Nordpool. At present, two power exchanges
are operating in India, namely, IEX and Power Exchange
