3 UCTE-IPS/UPS Study three major questions to answer Considering technical, organisational and legal issues the study has to answer the following questions: Is a synchronous coupling of IPS/UPS with UCTE feasible? What are the mandatory measures and requirements on both sides? What are the associated costs? Additionally, market aspects and environmental issues are building the conditional framework. First priority: maintaining the present performance of the systems with respect to system security and reliability. page 3 Matthias Luther, Tbilisi, 6 December 2007

4 Facts and framework of the project The three years investigation is a joint project under the responsibility of UCTE The project focus on a synchronous coupling of IPS/UPS and UCTE Additionally, the consideration of non-synchronous link projects is foreseen Budget: approximately 10 million Nearly 100 experts from both sides involved a unique synchronous transmission system under investigation - with 900 GW installed generation capacity - serving 700 million customers - in 10 time zones page 4 Matthias Luther, Tbilisi, 6 December 2007

16 Preliminary findings the necessity of the transmission network re-enforcements mainly dedicated to the IPS/UPS interface area a higher potential risk for the dynamic stability of the coupled systems compared to the present performance in the individual synchronous areas the adaptation and harmonisation of today s existing defence and restoration plans in both synchronous areas the need for interzonal, bilateral and multilateral agreements in order to setup a legal basis for a future reliable market platform with the focus on necessary organisational and operational issues under the framework of EU-market requirements and standards The preliminary results underline that - even if a synchronous coupling mode of operation may appear viable under the implementation of certain pre-conditions - it can only be understood as a long term option for creating a joint electricity market platform. page 16 Matthias Luther, Tbilisi, 6 December 2007

17 Outlook: expected results in 2008 An evaluation of the feasibility considering technical, operational, organisational and legal aspects based on available results An allocation of necessary measures and their associated costs to be made on both sides of the interface. An open outlook on non-synchronous system coupling possibilities aiming at an economic comparison for the investigated system coupling and an indication for the time horizon for a possible implementation for both variants. The final study results may form a basis for further steps under supervision of the European Commission and other stakeholders. Nevertheless, any decision need to be made by stakeholders taking into account the two further fundamental pillars - reciprocity in market conditions - compatibility of environmental standards including nuclear safety page 17 Matthias Luther, Tbilisi, 6 December 2007
