1.0 EXECUTIVE SUMMARY
Introduction
This report summarizes the training on Reactive Power and its importance for func-
tioning of the Power System provided by HIPP to the Georgian National Energy and
Water Supply Regulatory Commission. The workshop was conducted by Valeriy
Vlatchkov, HIPP Power Market Advisor, on September 4, 2012.
Goals
The primary goal of the workshop was capacity building of the Georgian Energy and
Water Supply Regulatory Commission as well as HIPP staff in Reactive Power is-
sues as a necessary tool for Georgian Power System for voltage and reactive power
control and reduction of losses in the power transmission and distribution networks,
improving the quality and continuity of supply. The main focus of the presentation
was on the critical task that lies before them: i.e. training the Georgian Regulator on
what kind of regulations and mechanisms exist in other countries for reactive power
control and what methodologies for calculation, what equipment and metering devic-
es are necessary for physically metering of the reactive power. Also focused on was
the question as to whether methodologies for control on reactive power are applica-
ble for Georgia.
Results
The participants were very interested in the topic and actively participated in discus-
sions about physical processes in transportation of electricity through transmission
and distribution networks and how reactive power impacts these networks. The par-
ticipants were interested also on what methods and mechanisms exists in reactive
power control and experience from other countries: USA, European Union and other
countries. GNERC representatives noted that it was the first time they looked at the
reactive power process in networks critically that would help them to perform their
regulatory tasks of the measures for eliminating existing discrepancies in the voltage
control and quality of services and quality of supply in Georgia.
4
The participants obtained a basic knowledge of the concepts of reactive power, the
need for implementation in Georgia methodologies for control of the reactive power
and it was agreed that standards for reactive power must be mandatory for all licen-
sees and they should be obliged to follow the standards for reactive power control
and to reduce the losses and to increase the quality of services and quality of supply.
The participants were pleased with the workshop, with many stating they had
learned concepts and information they had not been previously aware of or had not
adequately considered. The commissioner attending the seminar stated that the
GNERC should receive deeper knowledge of the concepts of reactive power and the
methodologies used in other regulators for creation and control the quality standards.

ANNEX IV
Questions from the workshop:
1. How the reactive power is metered?
2. How is the reactive power calculated and how it impacts on the electricity bill-
ing?
3. Does it exists in international practice reactive power compensating entities
and can we license it like a business?
4. How does ENTSO-E regulate Reactive Power problem?
5. In Georgia there are many transformers which are loaded by 10-15 %. How
should we regulate this issue?
6. Example of Kobuleti: One big transformer is working during all year- In Sum-
mer it is over-loaded and in winter it is under-loaded.
7. The big transformers are reactive power consumers when they are under
loaded. Can we replace them with small transformers?
8. Is it written in regulations how much reactive power is needed to transfer 1
kWh?
9. Example of Zahesi: Zahesi was obliged by Dispatch to produce reactive pow-
er without any compensation.
10. Can you provide legal basis or Reactive power regulation?
11. Can you provide information on methodology on reactive power regulation?
