Legal base

• According to Law of Georgia on
• Electric Energy and Natural Gas
• Commission by, its decision, approves volumes
  and calculation methods of allowable normal power
  losses.

3

• Method for identification of normal losses
• defines principles for calculation of normal
  power losses volumes
• It takes into consideration
• Tecnical losses in transmission and distribution
  networks
• _ Technical Losses are unevoidable power losses
  caused by the physical processes in wires and
  devices associated with transmission of power
  through electric networks.

4

• For the purpose of ensuring work of substations
  consumption of power for personal use
• -Consumption of power for personal use for the
  purpose of ensuring work substations means the
  volume of power (number), which is necessary for
  ensuring smooth functioning of substations and
  creating proper working conditions of the
  servicing staff.
• Losses due to instrumental discrepancies of
  measurements.
• -Losses of power due to standard instrumental
  measurement discrepancies means a part of
  non-accounted for power, not reflected on the
  meter on sites due to influence of standard
  technical parameters on results of accounting
  (negative systemic component of the discrepancy
  of the accounting system). Standard instrumental
  discrepancy of the accounting devices, in
  acceptable limits depends on burden of the
  relevant electric circuit.

5

• Factual losses of power difference between the
  power received to the network and that
  distributed to consumers, determined between data
  of the accounting system on received and
  transmitted power.
• Commercial losses losses caused by different
  reasons (including) stealing the power, which is
  determined incompliance between the data of the
  control meter and actually paid amount.

6
Losses Caused by Transmission of Power

• Losses caused by transmission of power shall be
  deducted from total losses of the power network
  of the company.
• LOsses caused by transmission of power through
  the licensed holder of the network shall not be
  reflected in the distribution tariff.

7
Calculation of Normative Losses

• Pursuant to legal requirements losses shall be
  calculated by the owner of the power network or
  any competent person upon order of the owner.
• Technical losses shall be calculated by the
  certified software.
• Values received by means of calculating the power
  losses shall be submitted to the commission for
  the purpose of approval of normative losses.
• The plan aimed at reduction of losses in the next
  year shall be submitted to the commission.

8
Approval of Normative Losses

• Accuracy of submitted calculations shall be
  reviewed and verified by the commission. If
  necessary, calculations may be transferred to an
  independetn expert for evaluation.
• In the end of each year, the license holders
  shall present the commission with the actual
  losses values as well as a structural analysis.
• In case of substantiated request of the license
  holder, losses may be corrected.

Resolution of the National Regulations
Commision of July 1, 1998, 3

• On Approval of Rules and Procedures for
  Methodology on Establishment of Electricity
  Tariffs
• The cost of energy and power fully reflects the
  losses of the transmission and distribution
  networks.
• Allowable volume of normative loss of power for
  each level of voltage for distribution and
  transmission shall be considered in the tariff.
• For the purpose of calculating the retail tariff,
  the cost of energy purchased by the distribution
  company, cost of power and distribution tariff
  are consolidated. The following is calculated
  with consideration of allowable losses.

• The sub-law in force
• Resolution of the Commission of May 11,2006,
  17
• On Approval of Normative Losses in the
  Electricity Network of the Georgian Energy
  System

11

• E
• Normative losses of electricity during
  transmission and distribution after putting the
  produced or imported electricity in the network
• Total losses 13,2
• on transmission - 4,41 (500-220-110-35 kv)
• on distribution - 110-35 kv - 2,8
• - 10 (6)-0,4 kv - 5,99

• Noramtive losses in networks of license holders
  out of the tiatl volume of electricity
• a) JSC Energo-Pro Georgia network 14,61
• 110-35-10(6)-0,4 kv
• b) JSC Telasi network 12,4 .
• 110-35-10(6)-0,4 kv
• g) JSC Kakheti Energy Distribution network
  10,5 .
• 10 (6) -0,4 kv

Dynamics of Determining Normative Losses in
Normative Acts of the Commission

• By decision of January 21, 2000, 2/2
• In the transmission network - (500-35 kv) 10,56
  
• Distribution networks 110-35-10(6)-0,4 kv
• Distribution networks - 13,0
• By decision 63 of July 12, 2002
• In the transmission network 500-35 kv 9,96
• In the distribution network 13,0
