10. November 1-3, 1995 – initial meeting of UCTE experts with Ukrainian specialists in Lviv. January 1996 – first meeting of the Technical Committee UCTE/CENTREL/Ukraine. 1995–1997 - elaboration and approval of the Catalogue of Measures on integration of the «Burshtyn TPP Island» toUCTE/CENTREL. 1999 –Agreement on long-term physical delimitation of Burshtyn TPP Islandfrom IPS of Ukraine was signed. April 6-20, 2002 – tests and 2 weeks trial operation of the «Burshtyn TPP Island» before connection to UCTE power system. July 1, 2002 –«Burshtyn TPP Island» was switched on one year trial parallel operation with UCTE. July 1, 2003 –Constant operation of «Burshtyn TPP Island» with UCTE. October10, 2004 – Resynchronization of II synchronous zone of UCTE. Switching on OHL 400 kV Mukachevo-Roshior (Romania) Establishment of the «Burshtyn TPP Island» Chronology of Events

11. “Burshtyn TPP Island”. Plans for Development • Increasing of capacity of existing units of Burshtyn TPP • Modernization of switching equipment and relay systems • Increasing of power export up to 600 – 650 MW • Development of fiber-optical communication lines

12. On the Way to Meet UCTE Requirements. Studies • Studies of the adequacy of Ukrainian normative documentation to the OH standards; • -Studies of the adequacy of the Ukrainian IPS for synchronous operation with European Power System (N-1, stability, voltage regulation, power reserve control, emergency procedures, information exchange, etc.); • -Studies of generation units to participate in primary and secondary regulation; • Studies of the electrical substations; • -Development of the Ukrainian Grid Code.

13. On the Way to Meet UCTE Requirements. Studies to Be Finished 2006 • Development of plan-schedule for II stage of HPP rehabilitation; • Harmonization of Ukrainian energy industry legislation in accordance with European requirements; • Development of project documentation for modernization of electrical substations; • Development of plan-schedule for modernization of TPP units to participate in primary and secondary regulation; • - Development of plan-schedule for voltage control modernization.

14. On the Way to Meet UCTE Requirements. Secondary Control - Installation of SCADA\EMS\AGC system - 400 MW of HPP is permanently under AGC control

15. On the Way to Meet UCTE Requirements. Network Construction • -Construction of OHL 330 kV HAES-Hmelnitska • -Construction of OHL 330 kV RAES-Lutsk Pivnichna • -Construction of N.Donbaska 500 kV substation • -Construction of OHL 500 kV Donbaska-N.Donbaska • -Increasing of voltage level of OHL RAES-Zahidnoukrainska to 750 kV • - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - • -Modernization of relay protection • Installation of SCADA\EMS\AGC system • -Construction of 1160 km of fiber cable communication link • -Installation of WAMS system
