Generation & Trading CIST GRID CODE: ORGANISATIONAL STRUCTURE

Generation & Trading CIST PROPOSED FUTUR ORGANISATION: 1 Steering Committee 3 Working Groups: Planning Connection Operation

Generation & Trading CIST 1 Steering Committee: The Steering Committee will be composed of one representative of each country Every request regarding the Grid Code evolution are submitted to the Steering Committee for evaluation. The Steering Committee approves the REM Grid Code The Steering Committee may mandated TSOs or Consultants to perform network studies (Stability, Short Circuit Power,..) on the whole region

Generation & Trading CIST PLANNING CODE: REM Systems Development Plan: This plan based on each System Reliability Forecast, is an overview of the regional transmission development. It is done every year for a time horizon up to 10 years Global REM Generation Adequacy REM Systems Modelling: The UCTE Standard of Data is adopted by the REM members in order to exchange information for performing studies

Generation & Trading CIST Protection System: The whole protection system must be compatible and the design protection for boundary substation have to be coordinated within the REM planning Working Group Defence Plan: Global REM plan against lost of synchronism: periodically reviewed REM under frequency load shedding plan: periodically reviewed Re-Energizing Plan: REM Working Group coordinates black-start capability

Generation & Trading CIST Overview to perform studies at the regional level in order to define the REM system development plan Overview to perform studies at the regional level in order to define the REM system development plan PLANNING CODE:

Generation & Trading CIST CONNECTION CONDITIONS: REM TSO shall ensure the regulated access to the transmission network in a non-discriminatory manner But it is allowed (in case of jeopardizing the system) to interrupt or modify the connection process

Generation & Trading CIST Additional requirements for Production: Frequency stability: - Primary Control - Secondary Control - Reserves Reactive Power Balance Behaviour in the event of system disturbances (transient stability/steady-state stability) Restoration of supply: - Tripping onto auxiliary supplies - Black start capability

Generation & Trading CIST Harmonisation of the criteria for system users in the whole regional system (equity) Harmonisation of the criteria for system users in the whole regional system (equity) CONNECTION CONDITIONS:

Generation & Trading CIST OPERATION CODE: Frequency Control: Each TSO must monitor the units response after activation and must store the data Level of reserve in accordance with UCTE requirement Cooperation within the REM TSO: Exchange of information Maintenance planning coordination: - Medium-term planning: 2 meetings/year - Short-term planning: monthly and weekly confirmation Special attention for the Power Plans’ planned outage

Generation & Trading CIST Voltage and reactive Power Control: Reactive Energy Exchanges have to be mutually agreed by the involved TSOs Exchanges Operation : TSO may object to a transit, which will jeopardize the security of its network

Generation & Trading CIST Emergency Operation: In case of emergency: Possibilities for TSOs of actions in order to avoid collapse (Reduction of Voltage level, Load shedding,..) Emergency Operation Plan: Coordination between the neighbouring TSO for emergency assistance

Generation & Trading CIST Restoration Plan: This Plan shall be coordinated between the REM TSO, it shall be updated and the restoration procedures shall be tested. The TSO shall maintain continuously communication between each other and for every case Back up facilities for communication Maintenance procedure for communication devices Operation Training: Joint Operators training from different TSOs

Generation & Trading CIST Coordination / Exchange of information between the TSO ’ s REM members, in accordance with UCTE rules Coordination / Exchange of information between the TSO ’ s REM members, in accordance with UCTE rules OPERATION CODE:

Generation & Trading CIST WORKSHOP FEEDBACK

Generation & Trading CIST WORKSHOP FEEDBACK: All the entities have attended this first Workshop Lecturers from EnBW, Powernext, CRE (french Regulatory Authority), Professor Chevalier (Paris University), RTE (French TSO), EKC and EDF General approach on: - electricity market - the balancing market - and the ancillary services

Generation & Trading CIST NEW WORK PLAN

Generation & Trading CIST NEW WORK PLAN: New version of the draft REM Grid Code, taking into account the comments: End of November REM National Grid Code draft: End of 2004

Generation & Trading CIST Implementation of the REM National Grid Code and the recommendations for the National Grid Code: End of March 2005 Third Steering Committee : April 2005 Second workshop: April 2005
