Market Shares and Structure
Indexes




In the reporting year 2011 the market shares of the three largest
generators made: Enguri HPP Ltd. – 32.6%; Mtkvari Energetika
Ltd. – 13%; Vardili HPP Cascade Ltd. – 5.8%.
The Herfindal-Hirschmann index for the same companies made
HHI=1,265.4, i.e. Georgian power generation market can be
assessed as moderately concentrated market.
As for the residual supply index, for Enguri HPP it makes
RSI=136%, i.e. its capacities are not representing main share in
satisfying the customers’ demand, so, it is not dictating at the
market.
Meanwhile, power distribution market is highly concentrated
(HHI=2,378.5) and significant market share is held by JSC
Energopro Georgia (42.6%).

Regulating Framework Promoting Energy
Efficiency and Renewables




According to the rules fro activity in power, natural gas and
water supply sectors and licensing rules:
Regulated utilities are obliged to reflect in the annual reports the
efficient use of resources indictors (the amount of resources spent for
generated power, volume of not used resources, etc.), technological
expenses for power generation and information on measures taken for
improvement of energy efficiency;
The volumes of actual losses in distribution company networks have
significantly reduced and they almost equal the values approved by the
Commission (save Kakheti Energodistributsia) – 1-2%;
The loss of hydroresources has significantly reduced in 2011 in
compare to the previous years;
In accordance with the power tariffs and tariff methodology:



Setting the actual cost-based tariffs supported flow of investments into
the sector; accordingly, improvement of metering and reduction of
commercial losses, as well as saving and efficient use of energy;
The losses over the norm are not reflected in the tariffs of power sector
utilities, and this gives them the incentive to optimise assets and load
regimes;
The step-wise tariffs set for the residential customers supports creation of
the additional social guarantees for the residential segment, as well as
saving and efficient use of energy;
According to capacity market rules:



The power transmitted by the small (up to 13 MWt) hydros to the network
without preliminary contracts are is considered purchased by CSO.
In particular, it is purchased: from September 1 to May 1, at the highest
tariff (price) of the power sold by power (capacity) generator to the CSO,
while from May 1 to September 1, at a tariff of HPP having regulated fixed
tariff, for which the Commission has set the lowest of them.
The above norm significantly improved financial status of small hydros and
created additional incentives for construction of new projects;
According to the rules of supply and consumption of power
(capacity):



The relations between retail customers and distribution companies were
regulated. This gives both parties the incentive to improve the power
supply/consumption regimes;
The direct sale-purchase of power between small PPs and retail customers
have been regulated, which also additionally stimulates small HPP activities
and promotes liberalisation of the retail market;
The terms for connection of the small PPs (up to 100 KWt) owned by the
retail customers to the generation distribution network have been defined
(access is free), and the obligation of purchasing the excessive power lies
upon the distribution company. The price is calculated by the following
methodology: the consumers’ tariff for the respective voltage level less
distribution tariff for the same voltage.
Main outcomes (1)


80% of the existing generation capacities is provided by the
renewables (hydro-generation).
In the nearest future, this value will reach 87%. 39 projects are being
constructed (38 HPP and one windmill with 50 MWt of design capacity),
with the 1,879 MWt of installed capacity and projected annual
generation of 7,410 GWtH.
Main Outcomes (2)


One of the main directions of the energy policy – increasing the share
of renewables in total generated power and satisfying the demand for
energy carriers by the own resources of the country – is successfully
implemented;
The state program Renewable Energy 2008 is being implemented; it
offers the investors the list of HPPs to be built in various regions of
Georgia (5 units; total capacity – 600 MWt);
ძირითადი შედეგები (3)


The program Development of Energy infrastructure, 2011-2013 is
being implemented. It includes the following components: promoting
investment into the hydro energy sector (attracting additional 70
million dollars for construction of 400 MWt capacities) and improving
transmission system (aiming towards improving energy security and
reliability and transfer capacities of the transmission system). In the
process of the project implementation, the free access to the networks
and sufficient transfer capacities for the priority access of the power
from new renewable sources and their export to various countries will
be ensured;
From the standpoint of improving the enrgy efficiency, it should be
mentioned that the peak load of the system has reduced by about 200
MWt, which should mainly be attributed to improvement of tariff and
metering systems;
Main Outcomes (3)



Actual losses of power in the system reduced more then twice (from
22% to 9.5%). This indicates towards the general improvement of the
situation in the sector and, at the same time, towards saving the
significant amounts of power (1,000 GWtH) and/or its more efficient
consumption (exports, etc.);
Big share of the consumed power (up to 30%) falls on the residential
sector. After arrangement of the tariff system and introduction of the
step-wise tariffs, about 47% of this segment consumes less then 101
KWtH, and this demonstrates serious motivation for power savings;
On the background of double increase of GDP (in compare to 2005),
the growth in power consumption made only 10% and consumption of
the natural gas has reduced by approximately 33% (in compare to
2006). This significantly improves the integral energy efficiency
indicator – the so called energy intensiveness (reduced about twice).

Main Challenges (1)


The law allows for introduction of the seasonal and daily peak
methodologies, although they are not developed yet. This would
promote the efficient use of energy resources, existing generation
capacities (for the reporting year 2011, the hydro resources equivalent
to approximately 600 GWtH of energy have been spilled) and
generated power;
The demand side load regulation and incentives shall be developed.
This would create the significant motivation for customers and network
companies to cooperate in th field of energy saving;
Main Challenges (2)


The systems of green certificates, CO2 trading credits and beneficial
tariffs for the alternative renewable sources shall be developed. This
would support the efficient use of the rich renewable resources existing
in the country;
The regulations of priority dispatch and access to the network of the
renewable generators shall be revised and updated, etc.
