Integration of Ukraine’s IPS into ENTSO-E is Ukrenergo’s key goal concerning development of trunk power grids.
It is an important element of Ukraine’s energy security. For in the end, we will have an enhanced reliability and balanced performance of Ukraine’s IPS, effective use of energy resources and significant increase of export capabilities.
Integration of Ukraine’s IPS into ENTSO-E is stipulated in the EU-Ukraine Association Agreement.
Today, only part of Ukraine’s IPS, the so-called Burshtynska TPP Island, operates synchronously with ENTSO-Е.
The “Island” includes Burshtynska TPP, Kaluska CHPP and Tereblia-Rikska HPP with the aggregate installed capacity of 2530 MW, infrastructure of Ukrenergo’s 220-750 kV power grids and distribution networks of electricity suppliers in the Carpathian region.
Modernization of the Island’s control systems and adjustment of capacity in accordance with requirements of UCTE (present-day ENTSO-E), test operation of the Island and a one-year test of “simultaneous operation” were held during 2000-2002. As a result, the Island switched to continuous simultaneous operation with UCTE effective 1 July 2003, and today, it handles transmission of Ukrainian electricity via interstate power lines directly to power systems in Slovakia, Hungary and Romania. The “Island” scheme allows to export up to 650 MW of electricity.
The matter of expanding UCTE’s synchronous area by including Ukraine’s IPS was first raised in 2005.
In 2006, Romania’s system operator Transelectrica has applied for expansion of the synchronous operation zone by including Ukraine’s IPS and Moldova’s PS.
In May 2006, the UCTE Managing Committee has accepted the application and launched a feasibility study consisting of three phases:
- research phase: inspection of Ukraine’s and Moldova’s power systems to determine the scope of measures required for simultaneous operation;
- implementation of the scope of measures required for simultaneous operation at the facilities of Ukraine’s and Moldova’s power systems;
- testing isolated and synchronous operation of Ukraine’s and Moldova’s power systems with ENTSO-E power grids.
In 2015, a consortium of ENTSO-E-member system operators studied the possibility of synchronous integration of Ukraine’s and Moldova’s power systems into ENTSO-E. The study has confirmed the absence of fundamental obstacles but revealed technical problems, which require detailed analysis and fixing.
In early 2016, the research phase of the feasibility study was accepted by ENTSO-E (Continental Europe Regional Group).
All reservations/nonconformities regarding operational and regulatory readiness of Ukraine’s IPS and Moldova’s PS will be described in the Action Catalog.
Beginning from June 2016, Ukraine/Moldova Project Group has been working on the Action Catalog, Synchronization Roadmap and the Agreement on Integration of Ukraine’s IPS into Continental Europe Synchronous Zone.
The next steps will include:
- fulfilment of technological and regulatory requirements (stated in the Action Catalog as an annex to the Membership Agreement);
- transition to isolated operation from IPS/UPS of CIS states;
- acquisition of membership and inclusion of Ukraine’s IPS to ENTSO-E.During the meeting of 23 May 2017 in Lisbon, ENTSO-E Continental Europe Regional Group has finalized the Agreement on Accession of the IPS of Ukraine to ENTSO-E. The signature of this Agreement in June 2017 must become the starting point for integration of the Integrated Power System of Ukraine into the European association.The Agreement on the terms and conditions of the future merger of Ukraine’s and Moldova’s power systems with the energy system of continental Europe, signed on 28 June during the ENTSO-E Assembly in Brussels, has entered into force on 07 July.
