                                                                  1
                                       Legal Framework and Basic Principles


   The Tariff authorities of the Commission are determined by the Law of Georgia on Electric Power and Natural Gas. The
    Commission is also obliged to take into consideration the main direction of state policies in the energy sector;
   The tariffs in power, natural gas and water supply sectors are set in accordance with the methodology approved by the Commission
    and other standard acts;
   The tariff regulation in power sector is effective since 1998, and the existing methodology has been approved in 2011;
   In Natural gas sector – since 1999;
   In water supply sector – since 2008;
   The tariff methodology in natural gas and water supply sectors is based on full cost principle, or includes costs and profit. The old
    power methodology was based on the same principle, while the new one is incentive based. It is based on the internationally
    approved marginal cost principles. Currently, the Commission is currently is developing the similar methodologies for the natural
    gas and water supply sectors.




                                                                                                                                     2
            Methodological Base



   The methodology allows the utility recovering reasonable costs;
   Supports growth of the financial outcomes of the utilities;
   Protects customers from the monopolistic prices, especially in the segments, where there is no competitive market in
    place;
   Reflects the differentiated costs of providing services to various types of the consumers;
   The Commission is authorised to set both fixed and capped tariffs.




                                                                                                                    3
                                     Types of the Tariffs



   In power sector the Commission sets and regulates generation,
    transmission, dispatch, transit-distribution, import and consumption, as
    well as CSO service and system capacity reserve tariffs. Released from
    regulation are small hydros (up to 13 MWt), exporters and newly built
    projects (since 2008);
   In natural gas sector the Commission sets transportation, distribution-
    transit an consumption tariffs;
   The ministerial ordinance of September 25, 2007 deregulated and partially deregulated
    the natural gas supply activities, i.e. according to the this ordinance, the natural gas
    supply is released from Tariff regulation, save the residential customers not using the
    natural gas for commercial purposes, and existing before the ordinance entered into
    the force. For this category, the natural gas supply has been partiallyu deregulated,
    and the capped tariffs were introduced;
   In the water sector the Commission sets drinking water supply and sewage
    tariffs.




                                                                                          4
                                Tariff Systems: Power Generation Tariffs



   In power generation sector the fised tariffs are set for regulating hydros (Enguri HPP, Vardnili HPP
    Cascade), all the other generation licensees are subject to capped tariffs;

   For the reserve sources the Commission sets two-rate tariffs. Price is set for the period of the source
    preparedness and provides for the compensation of the permanent costs;

   The guaranteed capacity sources, periods of providing the guaranteed capacities and the amounts of the
    capacities are approved by the Government of Georgia;

   The period of the guaranteed capacity source preperadness is defined by the “market rules”.

                          Transmission, Dispatch, Distribution, Transit and Consumers’ Tariffs



   There are two transmission and three distributioon licensees in Georgia;
   Transmission tariffs are fixed, while the distribution/transit tariffs are capped and differentiated by the voltage levels;
    the tariff for two distribution companies are set fro the long-term regulation period, with the respective mechanisms
    for revision and adjustment;
   In calculation of the transmission tariffs, the revenues received from the transit services are taken into account;
   The cost of normal losses in both, the transmission and distribution networks are taken into account in accordance
    with the existing legislation;
   In the process of tariff calculation, the obligation of presenting cost allocation lies upon transmission and distribution
    licensees; in case such allocation is not submitted, the Commission itself determines the allocation conditions in
    accordance with the voltages;
   The dispatch tariffs are set on basis energy volumes received by the eligible utilities at the receiving points;
   The consumers tariffs are set on basis of distribution utilities’ voltage levels and consumed volumes.




                                                                                                                             7

                                      New Tariff Regulation in Power Sector
                                    Basic Principles, Strengths and Weaknesses

   The power tariffs are set for the regulation period and the duration of the period is determined by the
    Commission;
   The tariff regulation periods are determined individually, based on the utility application or the
    Commission initiative;
   During this period or after its expiration, the tariffs can be adjusted in accordance with the conditions set
    by the Commission;
   As the regulation period grows, the revision costs become lower;
   Tariff stability during the regulation period makes this system attractive for the investors. The regulated
    utilities are given the partial freedom;

   The new methodology does not include the correction for X factor principle yet;
   It does not include the strict basic rules of allocation and does not reflect the interdependence between the
    tariffs and quality of service indicators.

                     Tariff Systems in Natural Gas Sector


                                                     Transportation Tariff
   Transportation tariff is mainly the same for all customers and is set at GEL 16.32/1,000 cubic meters, including VAT;
                                                              Transit
                                        The transit tariffs are not set by the Commission;
         The revenues received for the provided transit services are reflected in transportation taririff calculation;
                                                      Distribution Tariffs
                          The distribution tariffs are set by the pressure levels (high, medium, low);
            The distribution tariffs are set individually for each distribution utility and make (including VAT):
