  • The Feasibility of Synchronous Interconnection between IPS/UPS and UCTE 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 2 Matthias Luther; 26 October 2007

  • The Feasibility of Synchronous Interconnection between IPS/UPS and UCTE 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 interconnected systems compared to the current performance of both systems, 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 12 Matthias Luther; 26 October 2007
  • The Feasibility of Synchronous Interconnection between IPS/UPS and UCTE 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 13 Matthias Luther; 26 October 2007
