Complex of Ukraine: the present and the future”
Kyiv, International Exhibition Center, 8 November,
2017.

2. INTEGRATION OF THE UKRAINIAN ENERGY
SYSTEM INTO ENTSO-E:
PERSPECTIVES FOR UKRAINE

3. 2020 2025
New Energy strategy “Safety, Energy Efficiency, Competitiveness” is a principal document
highlighting strategic horizons of the energy and coal industry of Ukraine until 2035, approved
by the Government on 18 August 2017.
Implementation of the most actions to
integrate the IPS of Ukraine into ENTSO-E
by 2020.
Integration of the Ukrainian power system
and ENTSO-E continental Europe zone in an
operational mode by 2025.
ENERGY STRATEGY OF UKRAINE UNTIL 2035

4. WHY DO WE NEED CHANGES?
4% 96%
A complete synchronization of the Ukrainian power system with the ENTSO-E one as well as its separation from the
interconnected operation with the Russian and Belarussian power systems are the only ways to change the current situation.
The Ukrainian energy system is technologically connected to the power systems of Russia, Belarus and Moldova;
they operate in parallel as well.
It means the power systems operate in a common mode and the frequency is similar. An actual control of the
system is carried out by Russia as an owner of the greatest generating facilities.

5. AGREEMENT ON INTEGRATION OF THE UKRAINIAN ENERGY
SYSTEM INTO ENTSO-E
New energy market implementation is possible only within integration of the IPS of Ukraine to ENTSO-E
Advantages of synchronization:
• Strengthening of the reliability and resiliency of the IPS of Ukraine by means of facilities modernization according to the EU
standards within Agreement Action Catalogue implementation
• Diversification of the energy sources and transparent terms of the mutual assistance
• Introduction of the auxiliary services market (frequency control, ensuring the energy reliability and quality properties)
• Demonopolization of the domestic energy market by means of a competition right after ENTSO-E membership
• Increase the electricity trading by 4 times- up to 18-20 bln kWh/y
The Agreement on Conditions for Future Interconnections of the IPS of
Ukraine and PS of Moldova with the ENTSO-E energy system of the
Continental Europe was signed on the 28th of June 2017 in Brussels
The Agreement entered into force
on the 7th of July 2017.

6. BUSINESS BENEFITS FROM INTEGRATION WITH ENTSO-E
Transparent electricity pricing and stable
price for a long period of time
30 % decrease in the wholesale
electricity price in the long-term
perspective.
New options for electricity
trading
Choice of the energy supplier
Investor in the Ukrainian energy sector
gets an opportunity for free electricity
export
More than 85% of the electricity will be sold
under direct agreements between the energy
producer and supplier/consumer
4

7. This would increase the energy price by about 25-30% (similarly to the
European countries experience). The following process is inevitable.
Integration into ENTSO-E and free electricity trade with the EU
countries are the only ways to decrease the price.
5
The Law “On Electricity Market” was adopted as of 11 June 2017
NEW MARKET MODEL AND IMPACT ON THE ECONOMY
The Law stipulates a sector deregulation, direct agreements (energy producers may sell
the electricity directly to the consumers), market pricing within transportation and
distribution.
The industry of Ukraine consumed up to 41,46
(bln kWh) in 2016. Energy costs amounted to
UAH 71,17 bln
The industry shall additionally pay about UAH 18
bln within new market model.

8. IMPACT OF SYNCHRONIZATION: INDUSTRY
6
Synchronization with ENTSO-E will have a positive impact on the industrial complex of Ukraine
Electricity consumption within industry
(thousand kWh)
Industrial sectors to get the positive impact from the integration:
• Fuel industry
• Ferrous metal industry
• Non-ferrous metal industry
• Machine-building industry
• Chemical industry
• Food and processing industry
It is expected that the industrial enterprises as the electricity consumers will benefit after a general
decrease in the energy prices as the production process will be less costly.
Due to the Ukrenergo estimations the “day ahead” market energy prices will be 30% lower after the
synchronization.
The practical effect of similar processes regarding electricity cheapening due to the synchronization
with new energy markets may be observed in the Baltic states, especially in Latvia.
Total 41,469
Sector:
Coal 2 390 622 6%
Steel 24 063 787 58%
Chemical 1 583 170 4%

9. Synchronous operation with ENТSO-E allows to increase the electricity trading with the EU-countries using the
production facilities more efficiently (including NPP).
IMPACT OF SYNCHRONIZATION: ELECTRICITY TRADE
7
Scope of electricity trade with the EU countries will increase from
the current 4-5 bln kWh/year ($250 mln) to 18-20 bln kWh/year
($1,5 bln)
4-5
bln kwh/y

bln kwh/y
Taking into account the trader`s
operation profitability marginality (5 % on
average), the total income of the
electricity traders amounts to USD 75
mln/year

10. Free trade between Ukraine and the ENTSO-E countries will
strengthen the investment attractiveness of the energy sector of
Ukraine.
IMPACT OF INTEGRATION: NEW INVESTMENTS
8
There are three main producers of the conventional
energy in Ukraine:
• PJSC “Tsentrenergo”
• PJSC “Donbasenergo”
• “DTEK”
1 producer within hydro generation
• PrJSC “Ukrhydroenergo”
1 producer within nuclear generation
• SE “NNEGC “Energoatom”
• 180 producers within “green” generation
• The investments may be attracted not only in the
“green” sector but in the conventional energy
generation as well as it is demonopolized.
• There are new prospects for the energy export and
import.
Before integration into ENTSO-E After integration into ENTSO-E
Up to USD 700 mln of investments in the “green”
energy were attracted for the last three years.

11. Synchronization of Ukraine into ENTSO-E ensures the European norms of
consumer protection as well as service quality.
Ensuring the consumer with the right to choose is a key element of a free
market which is possible only via integration to ENTSO-E.
IMPACT OF SYNCHRONIZATION: CONSUMER PROTECTION
9
Any synchronization with ENTSO-E: new power market model may not come into force given a high probability of the
monopolists influence on the competition to preserve their excess profit.
Market coupling with the other countries allows to reduce the cost of electricity drastically. European power markets liberalization
proves a tendency of lower prices (Baltic countries). Ukrainian business and production in particular will become more competitive
on the foreign and domestic markets owing to the expected lower cost of prices.

12.  Technologically the synchronization with ENTSO-E will strengthen the stability
of the Ukrainian energy system and minimize the dependence on the coal
supply to the thermal units in Ukraine.
 Ukraine will have the opportunity to get the emergency aid from the ENTSO-E
countries power systems on commercial and competitive terms.
 Total technological level of the power system exploitation and the supplying
security level will be higher due to the ENTSO-E strict requirements for the
synchronization preparation.
IMPACT OF SYNCHRONIZATION: SECURITY ASPECT

13. KEY RISKS
Lack of proper coordination
Lack of funding
Lack of commitment from key stakeholders
Agreement execution requires a coordinated work of the market players on
the implementation of specific steps to modernization according to the
ENTSO-E rules.
Power units of the generating companies should be dramatically
modernized. Such actions should be funded by the market players.
Key stakeholders may be against the synchronization with ENTSO-E as they
are not interested in the power market demonopolization.

Within XV International Forum
“Fuel and Energy Complex of Ukraine: the Present and the Future"

16. Confidence building
Canada (Alberta)
Ukraine made several attempts to integrate into ENTSO-E Continental Europe power system during 2006-2014, however
they were not successful. For the first time Ukraine expressed its willingness in 2016.
The situation started to change in 2015, when Ukrenergo accelerated the action within this domain.
Ukrenergo performed a great scope of systematic work to restore confidence. One of the core element of such work was
building of partnership with countries whose experience was useful for Ukrenergo. Global standards and principles as well
as proactive position on the world stage made the Company more predictable and clear for foreign partners.
As a result, Vsevolod Kovalchuk, CEO at Ukrenergo signed the Agreement on Conditions for the Future
Interconnection of the power system of Ukraine and Moldova with the power system of Continental Europe
on 28 June 2017 in Brussels.

17. Close cooperation
• First phone workshop of the Ukrenergo and ENTSO-E
representatives held in February this year. We`ve approved the
strategic goals of future cooperation and shaped the primary
tasks.
• Large ENTSO-E delegation visited Ukrenergo to perform the 2nd
workshop. Up to 60 representatives of different competencies
and directions from the European and Ukrainian parties
established the cooperation strategies as well as perspectives of
the Ukrainian energy system synchronization with ENTSO-E.
As of today the integration of the Ukrainian energy system into ENTSO-E is a key priority of the Company
development. In order to achieve set goals Ukrenergo works closely with the ENTSO-E Secretariat and
attends regional and project groups meetings. Moreover, we have performed 2 joint workshops:

18. ENTSO-E Observer Member status
I. Unbundling– according to the Directive 2009/72/EC and the Regulation (EC) No 714/2009. The process
needs a political decision of the country`s governmental authorities regarding distribution of the main
energy assets (within gas and power industries).
II. Candidate should be defined as a transmission system operator (TSO) – due to the current legislation of
the country of origin (certification by the Regulator in accordance with the rules and procedures of the
Energy Community; it envisages the Ukrenergo unbundling and corporatization as well as possession of
Ukrenergo own grids).
III. Candidate should be interconnected with the ENTSO-E countries – due to the electricity market
conditions; as well the candidate should possess a direct contact with the interconnectors of the grid origin
country.

Ukrenergo aims to get the ENTSO-E Observer Member status.
It previews the implementation of the following actions:

19. Where are we heading?
Power generation units testing in early 2018. The output of the frequency and capacity primary regulation
will form a database for the upcoming analysis of the dynamic stability.
Active preparations for the testing are being performed at the power generation units as of today
(November-December 2017).
Establishment of the ENTSO-E TSOs consortium is previewed in the early 2018 to carry out the necessary
investigations of the Ukrainian energy system.
It is justified by the ENTSO-E legislative regulation prohibiting the involvement of the external investigation
models. We are currently working on the attraction of the companies as well as approval of the consortium
work area.
