“Burshtyn TPP Island”

• Territory – 27 000 km 2

• Population – 3 millions• Export potential – up to 550 MW• Internal consumption – 1000-1050 MW• Power plants – Burshtyn TPP (2300

MW), Kalush TPP (200 MW) and Tereblia-Rikskaya HPP (27 MW)

Establishment of the «Burshtyn TPP Island»

Chronology of Events

• 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» to UCTE/CENTREL.

• 1999 – Agreement on long-term physical delimitation of Burshtyn TPP Island from 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)

1. Increasing of capacity of existing units of Burshtyn TPP

2. Modernization of switching equipment and relay systems

3. Increasing of power export up to 600 – 650 MW

4. Development of fiber-optical communication lines

“Burshtyn TPP Island”. Plans for Development

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.

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.
