2 Context ACERs recommendations to ENTSO-E Electricity Balancing Framework Guidelines (FWGL) Promotion of coordination between TSOs regarding cross-border balancing mechanism as a necessary interim step towards the harmonization of the balancing markets in Europe and the implementation of the Electricity Balancing Network Code (NC) ENTSO-E call of nomination for balancing pilot projects with the aim to Gain experience in terms of implementation of inter TSO regional balancing mechanism Test the feasibility of the balancing target model identified in the FWGL Evaluate the associated implementation impact The experience gained with the pilot projects will be reflected in the future developments of the NC TERRE Pilot Project In this framework, National Grid, REN, RTE and TERNA proposed the Trans- European Replacement Reserves Exchanges project (TERRE Project)
3 Scope of TERRE pilot project Scope: Design and test the feasibility of a multi-TSO coordinated exchange of Replacement Reserve - Cross Border Balancing Energy Participants Terna, RTE, National Grid Electricity Transmission Plc, National Grid Interconnectors Limited, REN Swissgrid and REE expressed their interest to the project and could join the project during the design phase Project phases: Design phase (started in 2014) – Currently in progress Implementation phase (will be started between end of 2014 and beginning of 2015 – it depends on the progress of the whole aspects of the project) TERRE design phase aims to design a solution compliant with the requirements of: The ENTSO-E proposal of standard product The NC (1/centralized and automatic management of XB capacities, 2/in a first step, offers based on cheapest internal bids, in a second step, all internal bids offered, 3/improved matching process)
4 Working axes Definition of the standard TERRE products (TERNA) Definition of RR offers and RR needs Definition of matching process and settlement procedure (RTE) TSOs RR needs netting FCFS or Implicit Auction Marginal price or pay as bid Financial issues (NGET) Definition of financial settlement between TSOs Study of the potential financial benefit Timing and scheduling (REN) ATC management (RTE & NGIC) Centralized ATC management Interaction between the ID market and TERRE process Governance issues (All)
5 Updated status of the project – main achievements (1/2) MoU and NDA covering the design phase Signature process still in progress Definition of the standard TERRE products Based on the requirements of the ENTSO-E ancillary services working group (WG AS) in charge of the definition of Balancing Standard Products All TSOs expressed their proposals on the values and constraints that each characteristic of TERRE product should respect TERNA is merging all the proposals in order to define a common set of minimum requirements for TERRE products Full Activation time (from LFC-R) Full Activation time (from LFC-R) Full Delivery Period 1- Request time 2- Preparation period 3- Ramping period 4- Min & max bid size 5- Min & max delivery period 6- Deactivation period Characteristics defined by the WG AS
6 Updated status of the project – main achievements (2/2) Definition of matching process and settlement procedure A qualitative study has been initiated and is now under review by all TSOs: both FCFS and Implicit Auction methods are compared according to criteria Data collection has been launched in order to assess the volumes and characteristics of balancing offers available in each country The feasibility of a quantitative study is under investigation Financial issues Data collection has been launched in order to assess the potential financial benefit of TERRE RTE has developed a balancing simulation facility tool. This tool optimizes (by applying balancing cost minimization) the selection and allocation of balancing supply quantities to address a balancing demand, taking some technical constraints into account RTE proposed to the TERRE project group to use this for processing financial simulation. This point is under discussion.
