War destruction of 400 kV and 220 kV transmission facilities in Croatia and Bosnia-Herzegovina (particularly Ernestinovo and Mostar substations) led to separation of UCPTE synchronous area

Soon afterwards re-connection declared as UCPTE priority, but without own financial means UCPTE/UCTE has focused on keeping technical cooperation between two separated zones and leading supporting and explanatory activities with aim of their reconnection

Origins and the beginning of re-connection processOrigins and the beginning of re-connection process


Preparation of UCTE re-connection

Intesifing of UCTE activities with signing of MoU in May 2001 among UCTE and its members fromCroatia (HEP), Bosnia-Herzegovina (JPCC) and FR Yugoslavia (EPS) in order to facilitate re-connection

In 2002 financing secured for key infrastructure :– in Bosnia-Hercegovina with international “Power III Project” for

electricity infrastructure reconstruction – in Croatia with domestic funds for investment in transmission

(re)construction program


Realized main infrastructure improvements

HEP (Croatia) reconstructed Ernestinovo substation with adjoing 400 kV lines and new Žerjavinec substation

ZEKC (Bosnia-Herzegovina) reconstructed 400 kV lines Mostar-Gacko, Mostar-Sarajevo

Substantial investments in secondary equipment on main lines across interface and involved control blocks


Final steps before re-synchronizationMultilateral Re-synchronization Program (MRP) signed by

ET members and aprooved by UCTE SC (in Sep.2004)as a summary of ET work and a basis for the realisation of re-synchronization starting from 9.10 hours (CEST) on October 10th (Sunday) coordinated by ET co-convenors as main coordinators of re-synchronization process from HEP in Zagreb,in direct communication with nominated participants from all involved control centers

Implementation went succesfuly according to the program

After re-synchronization

Operational test phase of reconnected system is envisaged until end of October with the purpose of monitoring and analysis of operation

During that period commercial exchanges across former interface between two synchronous zones will not be scheduled

If the evaluation of test phase will be positive UCTE will issue a statement by November 1st, 2004 specifying the exact date for the start of respective exchanges and how such exchanges may gradually be increased up to the full NTC values


Recommendation to markets (1)

Bearing in mind the responsibility of each single TSO towards its customers, but aiming at monitoring the global system response to the new flow patterns, UCTE recommends to TSOs along the former interface the following capacities:


Recommendation to markets (2)

From 1 Nov to 30 Nov:30% of the NTC values (according to UCTE calculations and as published on the ETSO website http://www.etso-net.org) in the direction from the former 2nd zone to the 1st zone

From 1 Dec to 31 Dec:60% of the NTC values (according to UCTE calculations and as published on the ETSO website http://www.etso-net.org) in the direction from the former 2nd zone to the 1st zone

From 1st Jan 2005 on:Return to usual NTC definition / publication proceduresincluding necessary re-assessment of NTC values.


Integration of Albania and Turkey

UCTE set up a TC to provide KESH (OST) with a more robust status as well as specific responsibilities within the UCTE community that might lead after a consolidation period to UCTE membership

Will launch with EU funding support a

feasibility study about the requested synchronous interconnection of Turkey (TEIAS system) with UCTE


OH and MLA (1)OH and MLA (1)

OH and MLA = contractual dimension to TSO co-operation enforceable first among TSOs and at a later stage to all grid users via a close co-operation between UCTE and CEER/ERGEG;

OH and MLA procedures may put to light non-compliance cases of single TSOs all over Europe.

However, no specific compliance problem expected for the TSOs of the SEE region (compared to other UCTE regions);


OH and MLA (2)OH and MLA (2)

Since non-compliance cases may be not due to the respective TSO action, but to their political and/or regulatory environment close co-operation of governments and where existing regulatory authorities of SEE with the ERGEG/CEER structures working together with UCTE;

OH and MLA will be completed by a new preventive process Compliance Monitoring and Enforcement Process (CMEP).
