Why 2012 Will Be So Importantfor the Restructured TurkishElectricity Market
Turkey has initiated an electricity sector reform since2001, with the encouragement of retail competition statedas a key aim of the reform process. Though Turkey has hitmany milestones, uncertainties still exist regarding theretail market, meaning further steps will need to be takenin 2012.

I. Introduction
The electricity industry was
dominated by vertically integrated
companies before the
embracement of a reform process
including liberalization,
privatization, and restructuring of
electricity industry by many
countries in 1980s. Even though
many countries from different
regions and income levels have
opted to restructure their
electricity industries, the motives
behind the restructuring process
differ. Electricity reform has been
adopted in response to technical
ier Inc. All rights reserved., doi:/10.1016/j.tej.2
shifts in developed industrial
countries. In those countries, the
reform process has been motivated
by a desire to capture efficiency
gains by ensuring competition. By
contrast, electricity reform has
been implemented as a remedy for
financial mismanagement, poor
governance, and a failure to meet
the social contract in developing
countries and in some transition
economies.1
A lmost all of the means and
policies implemented by
the countries reforming their
electricity markets are identical.
Littlechild summarizes the main
011.10.018 The Electricity Journal
Even thoughTurkey hastaken manysteps, someuncertaintiesstill exist regardingretail electricitymarket.
D
pillars of the textbook model for
restructuring and competition in
electricity markets: Privatization,
vertical separation of competitive
and regulated monopoly sectors,
horizontal restructuring to create
an adequate number of competing
generators and suppliers,
designation of an independent
system operator, creation of
voluntary energy and ancillary
services markets and trading
arrangements, application of
regulatory rules to promote access
to the transmission network and
incentive efficient location and
interconnection of new generation
facilities, unbundling of retail
tariffs and rules to enable access to
the distribution networks in order
to promote competition and at the
retail level, specification of
arrangements for supplying
customers until retail competition
is in place, creation of independent
regulatory agencies, and provision
of transition mechanisms that
anticipate and respond to
problems and support the
transition rather than hinder it.2
R etail competition is
promoted to allow
consumers to choose their
suppliers. Those retail suppliers
have the right of access to the local
distribution network to which the
customers have connected.3
Littlechild states that the social
value of electricity retailing is that
it establishes the prices which are
the best that suppliers can offer at
any time, and it identifies how
these prices differ by product
attribute, such as time of day and
duration into the future. This
situation lets retailers, customers,
ecember 2011, Vol. 24, Issue 10 1040-6190/$
and generators make more-
informed decisions.4 Joskow
argues that a successful retail
competition program can also
provide additional social benefits
by helping to improve the
performance of wholesale
markets.5
R etail competition is directly
suggested and promoted by
European Union (EU) directives.
The directive 2009/72/EC states
that in order to develop
competition, large non-household
customers should be able to
choose their suppliers and enter
into contracts with several
suppliers. On the other hand, it
should be noted that many U.S.
states have not adopted retail
competition programs. Electricity
consumers are still served by
regulated vertically integrated
utilities in those states.6
The introduction of competition
in retail markets should increase
consumers’ choices, reduce
barriers to entry, and encourage
innovation and lessen prices.
However, the results of retail
competition where it has been
implemented are still a matter of
–see front matter # 2011 Elsevier Inc. All right
debate. For example, Defeuilley
claims that the current situation of
retail electricity markets shows
that the expected results did not
always materialize.7 On the
contrary, Littlechild states that the
subsequent outcome of retail
competition is above expectations,
since initial expectations were low.
He claims that where retail
competition is allowed to develop,
customers remarkably prefer to
change their suppliers.8
Turkey has initiated an
electricity sector reform in parallel
with many other countries since
2001. The Electricity Market Law
(EML)9 was enacted in 2001 as the
first step of the reform process. An
independent regulatory body, the
Energy Market Regulatory
Authority (EMRA), was
established to regulate the
electricity and natural gas
markets.10 Although many
intentions of EML have not been
executed yet, the Turkish
electricity market has evolved
enormously since 2001 as a result
of the effort to create a liberal
market. Encouraging retail
competition has also been stated as
one of the aims of the reform
process in the country. Even
though Turkey has taken many
steps, some uncertainties still exist
regarding retail electricity market.
The main aim of this article is to
analyze the retail segment of the
Turkish electricity market. First,
Turkish electricity reform and
market structure will be
explained briefly. Then, the retail
segment will be analyzed and
assessed. Finally, the reasons that
will make 2012 highly significant
s reserved., doi:/10.1016/j.tej.2011.10.018 71
72
will be explored, and some
projections and recommendations
also drawn.
II. Turkish ElectricityReform and CurrentMarket Structure
The private sector wasgiven the right to
compete in marketsegments such as
generation andwholesale trading via
obtaining a license fromEMRA.
The year of 2001 may be
accepted as the commencement of
the reform process in the Turkish
electricity industry. The new
electricity market law, EML, was
enacted in that year aiming to
ensure the development of a
financially sound and transparent
electricity market functioning in a
competitive environment. EMRA
was established in order to
regulate the electricity market.
The private sector was given the
right to compete in market
segments such as generation and
wholesale trading via obtaining a
license from EMRA.
Electricity transmission
activities are conducted by the
state-owned Turkish Electricity
Transmission Co. (TEIAS).
Distribution activities are
performed by 21 regional
distribution companies. Twelve
of these are held by the private
sector, and the privatization
process of the other nine is
continuing.11 According to EML,
the distribution companies also
have to obtain a retail sales license
and supply electricity to
consumers in their regions if there
are some consumers unable to
purchase electricity and/or
capacity from a supplier. It should
be noted that currently there are
no retail sale companies except for
1040-6190/$–see front matter # 2011 Elsev
distribution companies that hold
retail sale licenses. In fact, all of
the non-eligible consumers have
to buy electricity energy from
these distribution companies.
The biggest electricity producer
in the country is the state-owned
Electricity Generation Co.
(EUAS), its subsidiaries, affiliates,
and partnerships. Other
generators are the companies that
have build-operate-transfer
(BOT), build-operate-own (BOO)
and transmission of operational
rights (TOOR) contracts;
independent power producers,
and self-generators.12 The
privatization of some power
plants held by EUAS is in process,
although the major hydro plants
are planned to remain under the
umbrella of EUAS.
There are 125 private wholesale
license holders in the Turkish
electricity market.13 Furthermore,
the Turkish Electricity Wholesale
Co. (TETAS), a state-owned
company, has a wholesale license
to trade the electricity purchased
from the power plants having
BOT, BOO, and TOOR contracts
with the government.
ier Inc. All rights reserved., doi:/10.1016/j.tej.2
B ilateral contracting and the
balancing and settlement
market are the two main means
for market participants to trade
electricity. The state-owned
EUAS sells electricity to the state-
owned TETAS whereas EUAS’s
subsidiaries, affiliates,
partnerships, and portfolio
generation groups sell electricity
directly to the distribution
companies. The power plants
generating electricity within the
framework of BOT, BOO, and
TOOR contracts sell all of their
electricity to TETAS. TETAS,
purchasing electricity from EUAS
and within the context of vesting
contracts, provides electricity to
the 21 distribution companies.
TETAS, in addition, supplies
electricity to some eligible
consumers to whom it supplied
electricity before the enactment of
EML. However, if these eligible
consumers negate their contracts,
they lose the right to purchase
electricity from TETAS.
Independent power producers
provide electricity to eligible
consumers or wholesale
companies by bilateral
contracting. Self-generators also
have the right to sell one-fifth of
their generation in the market.14
The volume of the trade between
independent power producers
and distribution companies is
very low, primarily for two
reasons: (1) prices in the balancing
and settlement market are more
alluring, and (2) there are
contracts between distribution
companies and TETAS or EUAS’s
subsidiaries, affiliates, and
partnerships forcing the
011.10.018 The Electricity Journal
D
distribution companies to
purchase electricity from those
state-owned suppliers. The
contracts will be in force by the
end of 2012.
T he current installed
electricity capacity of Turkey
is approximately 50,985 MW.
Approximately 30.2 percent of
capacity is constituted by natural
gas plants and 33.1 percent by
hydropower plants. The total
electricity consumption of the
country in 2010 is 210,434 GWh.
Approximately 45 percent of
electricity was generated by state-
owned EUAS and its subsidiaries,
affiliates, and partnerships, and 30
percent was generated by the
power plants having BO, BOT, and
TOOR contracts. The share of
generation of independent power
producers was 19 percent and that
of self-generators was nearly 6
percent.15

A. Envisaged retail marketstructure
Figure 1: Opening Rate of Turkish Electricity Market (%)
A transparent electricity market
operating in a competitive
environment is one of the main
aims of the restructuring process.
In parallel with that aim, EML
envisages the creation of an
electricity market structure with
many market actors, particularly
in the generation, wholesale, and
retail segments. Retail and retail
service activities are conducted by
retail sale companies and
ecember 2011, Vol. 24, Issue 10 1040-6190/$
distribution companies holding
retail sale licenses in accordance
with provisions of EML and other
regulations. However, as
mentioned, currently there are not
any retail sale license holders apart
from distribution companies.
A strategy paper titled
‘‘Electricity Energy Market
and Supply Security Strategy
Paper’’ was prepared and
accepted by Higher Board of
Planning in May 2009. The
strategy paper states that all
consumers except for residential
consumers are planned to be
eligible consumers by the end of
2011. That means consumers
whose electricity consumption is
nearly 80 percent of total
consumption will be able to
choose their suppliers via
bilateral contracts. By the end of
2015, all of the electricity
consumers will be eligible,
according to the strategy paper.
It is stated in the strategy paper
that distribution companies
performing distribution,
generation, and retail activities
have to separate these activities
–see front matter # 2011 Elsevier Inc. All right
by the beginning of 2013. After
2013, these activities will have to
be carried out under separate
legal entities. Therefore, in respect
to this aim, new retailers except
for distribution companies should
be allowed to display activity in
order to ensure a retail market
with many actors.
Currently all consumers can
purchase electricity from
distribution license holders even
though their consumption level is
above the eligibility limit. Almost
90 percent of electricity is sold by
distribution companies to final
consumers via regulated tariffs.
However, EMRA may prefer not
determining and approving
tariffs for industrial or
commercial consumers in 2013.
B. Market opening

opening rate in Turkish electricity
market is nearly 75 percent.
However, the level of trade is
much lower than the opening
rate.
T he 75 percent theoretical
market opening rate does
not necessarily reflect the ratio of
electricity that is or can be traded
among market players. Although
the opening rate is 75 percent
when it is calculated from the
consumers’ side, only about 30
percent of total electricity
production can be traded in the
free market, as the total installed
capacity of independent power
producers and self-generators is
less than 35 percent.16
Nevertheless, as a result of
decreasing the eligibility limit, the
number of customers purchasing
electricity from suppliers in the
market has increased, as shown in
Table 1.17
C. Entry and exit in the retail
market
According to EML, any entity
having a retail license can
undertake activities in the retail
market. However, as mentioned,
currently there are no market
actors holding a retail license
except for distribution companies.
So, there is an implicit barrier to
becoming a market actor in the
retail segment since EMRA has
not granted any retail licenses.
Here, it should be noted that
most of the trading activities
performed by wholesale licensees
are related to retail sales. The
licensees purchase electricity
from generators or in the

balancing and settlement market
and sell that energy to eligible
consumers. That is, most of the
125 wholesale companies are
directly engaging in retail
activities in the market.
In Turkey, the movements of
eligible consumers are restricted
in 2011, as well. Eligible
customers purchasing electricity
from distribution companies
cannot leave these companies
whenever they want. They have
to start to buy electricity from
suppliers via bilateral contracts at
the beginning of quarters: Jan. 1,
April 1, July 1, or Oct. 1. On the
other hand, an eligible consumer
buying electricity from a supplier
ier Inc. All rights reserved., doi:/10.1016/j.tej.2
can return to the distribution
company whenever it desires. The
reason for the restriction on
switching was to preserve retail
license-holder distribution
companies from the fluctuations
as these companies have
enormous purchasing contracts.
However, in our opinion this
restriction is not consistent with
the planned market structure. The
solution should be to decrease the
amount of obligatory contracts,
not to limit switching.
D. Effects of the vesting
contracts
Although the creation of retail
competition is stated as one of the
purposes of the reform process,
the government has vesting
contracts and state-owned
companies have a significant
share in total electricity
generation. Therefore, as
mentioned before, regional
distribution companies which
also sell energy have to buy all of
the energy generated within the
context of vesting contracts.
Distribution companies are the
primary suppliers in the current
market structure. However, they
cannot buy most of the electricity
via bilateral contracts from
independent producers. Since
they cannot have a word while
determining the prices in the
contracts with TETAS and EUAS,
an inefficient trade emerges.
Therefore, this obligation should
not be the responsibility only of
distribution companies. The
vesting contracts cannot be
eliminated, but all suppliers (and
011.10.018 The Electricity Journal
D
customers) should be responsible
for paying for the cost of vesting
contracts in order to create an
efficient nature for competition
and ensure equality.
E. Effects of regulated tariffs
An inquiry done by the
European Commission shows
that regulated tariffs have
produced adverse effects for the
development of competitive
markets in several member states.
The main reasons are the low
levels of regulated tariffs
compared to market prices and
their covering of a large part of the
market. It is also recommended
that special measures to reduce
electricity bills in several member
states should be made compatible
with antitrust and state aid
rules.18
T urkey is no different in
seeing adverse impacts from
the regulated tariffs. Regulated
prices are determined via a
methodology that includes cross-
subsidization within different
consumer groups. There are 24
regulated consumer groups in
[(Figure_2)TD$FIG]
Figure 2: Average Hourly System Day-Ahead
ecember 2011, Vol. 24, Issue 10 1040-6190/$
Turkey, each with a different
regulated energy price. Due to a
provision in EML and a decision
made by the Council of Ministers
in 2007, some groups pay a higher
rate than the cost of the energy
delivered to them, while other
groups pay less. In fact, some
consumers, particularly
commercial consumers, subsidize
other consumers, particularly
industrial consumers purchasing
electricity via regulated tariffs.
The regulated electricity energy
prices are used as an index in
bilateral contracts, and the prices
determined in the contracts
between eligible consumers and
suppliers do not reflect the real
costs. The suppliers (generators
and wholesale companies) take
advantage of the margin between
regulated tariffs and wholesale
prices constituted in the balancing
and settlement market. The
bilateral contracts usually do not
set fixed prices or costs and the
variable price is determined as a
ratio of regulated prices. In
addition, before 2011, eligible
customers did not have to finance
the cost of non-technical losses,
Prices and Regulated Prices (2010)
–see front matter # 2011 Elsevier Inc. All right
while customers purchasing
energy by regulated tariffs had to.
The natural consequence of all
this is an inducement to the
wholesale/retail trade to take
advantage of the flaws.
Figure 219 shows the average
hourly system day-ahead prices
and the regulated industry and
commercial energy prices in 2010.
The difference between system
day-ahead prices and these
regulated tariffs pushes
customers in these two groups,
especially in the commercial
group, to buy energy from private
wholesalers. It is, of course,
preferable that eligible customers
purchase energy in the market.
Unfortunately, the increasing
level of trade between private
parties was not a result of
competition on costs but due to
the cost of cross-subsidization.
T hese various flaws in the
system lured capital holders
into establishing wholesale firms
to take advantage of the price gap
between regulated tariffs and spot
prices. Actually, the wholesale
firms do not have to be capital
holders. They can display any
s reserved., doi:/10.1016/j.tej.2011.10.018 75
76
activities in the balancing and
settlement market without
collateral. This has left many
insolvent companies trading
energy in the market, which is
unacceptable in a liberalized
market. Fortunately, the
wholesale firms will have to pay
sufficient collateral beginning
December 2011.
IV. Why 2012 Is SoImportant andConcluding Remarks
EML envisages a transition
period by the end of 2012
regarding some market activities.
Cross-subsidization, obligatory
energy purchase contracts
between distribution companies
and state-controlled generation or
wholesale companies, allowance
of activities such as generation,
distribution and retail without
establishing different legal
entities, and implementation of a
national tariff scheme are allowed
in the transition period. Since the
transition period ends by the end
of 2012, important steps must be
taken in 2012 in order to insure a
viable well-functioning market.
O ne of the issues that should
be fixed in 2012 is the
determination of a supplier of last
resort, which emerges as a
significant issue following the
introduction of retail competition.
The supply of last resort, broadly,
implies servicing the customers
who don’t choose their suppliers.
Supply of last resort is an
important means to protect
consumers who might be unable
1040-6190/$–see front matter # 2011 Elsev
to choose their suppliers and to
obtain energy. In the EU,
‘‘supplier of last resort’’ and
‘‘default supplier’’ are
understood in many different
ways, but it is usually the
incumbent energy supplier who
acts as both and this service is not
time-limited. However, this
serves as a barrier to new
entrants. Therefore, to promote
competition, ERGEG
recommends a tendering
procedure for appointing a
default supplier/supplier of last
resort, and also time-limiting
these services.20
Who will be responsible for
supplying energy as last resort is
not clear in the Turkish legislation.
What is most likely is that the
distribution companies or the
retail parts of the distribution
companies will have the
responsibility for being suppliers
of last resort. The issue will have
greater importance by the
beginning of 2013, as almost all
consumers except for households
most likely will be eligible
consumers. The determination of
responsible suppliers and the
ier Inc. All rights reserved., doi:/10.1016/j.tej.2
tariffs to be implemented for non-
eligible customers will be crucial.
In brief, preparing sufficient
legislation, developing a
methodology, and building
awareness is one significant duty
that EMRA will have to
accomplish before the beginning
of 2013.
In my opinion, assigning the
distribution company to be
supplier of last resort is better
than the separated retail entities
from the distribution companies.
Correctly determining and
analyzing the costs of different
consumer groups will not be easy
when the retail company is
appointed as supplier of last
resort. Furthermore, the
distribution companies have to
purchase the amount of energy
that is lost in the network,
implying they will have to
continue to purchase energy. If
they are chosen as supplier of last
resort, the concerns about implicit
cross-subsidization between
regulated and unregulated tariffs
will be removed.
According to EML the cross-
subsidization of electricity prices
among different consumer
groups should be removed by the
end of 2012. A gradual transition
is required in order to lessen the
effects of removing cross-
subsidization on groups,
especially industrial customers.
Otherwise, a big change in a short
period will be unavoidable and
the consumers will not be ready to
overcome the serious change in
prices and market structure. Also
making a determination to
remove cross-subsidization is
011.10.018 The Electricity Journal
D
very crucial since the system is
not a closed one and the
subsidizing groups may leave the
regulated energy tariffs due to
high prices and alternative lower
prices in the market. The main
group subsidizing other groups is
the commercial sector. This sector
has a tendency to leave regulated
tariffs. When they leave, financing
subsidized groups will be very
hard and ensuring the
sustainability of cross-
subsidization and regulated
energy tariffs will be impossible.
In brief, implementing the
methods to remove cross-
subsidization is necessary, rather
than looking for means to make
some groups subsidize other
groups via regulated energy
tariffs. This problem should be
solved in 2012 in order to show
the commitment to the reform
process.
W holesale and retail
activities should be
redefined in 2012 and new
retail licenses should be
granted in order to create
competition in the retail segment.
Otherwise, the separated sections
of the current distribution
companies may take advantage of
not having many rivals in the
market.
The obligation of distribution
companies to purchase energy
due to vesting contracts will
properly be removed at the end of
2012. A new mechanism to
distribute the cost of vesting
contracts will need to be created
by this time. If not, extending the
obligation may emerge on the
agenda of the government, which
ecember 2011, Vol. 24, Issue 10 1040-6190/$
in turn might create distortions.
All the energy generated in the
context of vesting contracts or by
EUAS should not be sold to the
distribution companies or the
retailers which will be separated
from distribution companies. It is
apparent that at least some of the
vesting contracts cannot be
removed, but a mechanism
allocating the cost to all the
suppliers (and therefore all the
customers) may be created. A
mechanism which may be
designed and managed by the
operator of the balancing and
settlement market ensuring that
all the suppliers and customers
are sharing that cost may be
established. Another option is
forcing the state-owned
wholesale company, which is
responsible for purchasing
electricity generated in the
context of vesting contracts and/
or state-owned generators, to
perform in the competitive
market. Finally, if all the purchase
obligation cannot be removed, the
distribution companies just
should be responsible to purchase
enough to meet the demand
–see front matter # 2011 Elsevier Inc. All right
associated with system losses and
residential consumers.
A cceleration of the
privatization of generation
held by state-owned portfolio
groups would be helpful for
minimizing the uncertainty and
constituting a more liberal
market. It is mentioned in Section
II that the market opening from
the generation side is just 30
percent, whereas at least 80
percent of consumers will be
eligible consumers by the
beginning of 2012. Privatization is
a prerequisite to provide new
opportunities for eligible
consumers and to ensure the
profundity in the market.
The division of duties between
distribution companies and
suppliers is not clear in Turkey.
The distribution companies are
implicitly responsible for
metering. Since eligible
consumers can purchase energy
from wholesalers or directly from
generators, the distribution
companies send the metering
values and bills for network
costs to those suppliers.
The suppliers collect the
money from the customers and
transfer the amount regarding
network activities to the
distribution companies.
However, this process is
not a written process. A
coherent regulation spelling
out the responsibilities of parties
regarding metering, invoicing,
etc., might be beneficial before the
separation of retail and
distribution activities.
Signing bilateral contracts is
one of the major ways to purchase
s reserved., doi:/10.1016/j.tej.2011.10.018 77
78
electricity in the competitive
market. Unfortunately, in Turkey,
the general understanding of
bilateral contracts is limited to
contracts signed by the parties
face to face. There are not any
over-the-counter (OTC) markets
in Turkey. That has created an
asymmetry of information
between parties, precipitating an
illiquid market. Forming OTC
markets might be helpful for
development of a more
competitive and transparent
market.
A national tariff scheme is
implemented in Turkey.
All consumers in the same group
pay equal network costs per unit
regardless of which distribution
region they are in. Ineligible
consumers who purchase
electricity via regulated tariffs
again pay for the national
electricity energy price
determined for the group they
belong to. The national tariff
should be superseded by regional
tariffs in the beginning of 2013,
according to EML. Hence, some
coherent decisions are required in
2012 regarding the
implementation of regional
tariffs. Furthermore, the number
of consumer groups, currently 24,
should be decreased, by
introducing fewer, broader
groups.
To conclude, Turkey clearly is
committed to restructuring its
electricity industry and has
adopted a roadmap. However,
some key supporting decisions
need to be made in order to form a
retail market consistent with the
purposes of the restructuring
1040-6190/$–see front matter # 2011 Elsev
process. If a bifurcation of policies
is implemented by the
government at the same
time, uncertainty inexorably
will emerge. Hence, the
restructuring process should
be advanced as envisaged
and the inconsistencies removed
as soon as possible. As the last
year of the transition period, 2012
is the year to alleviate the
uncertainty and adopt policies
consistent with the main goals of
the country.&
