  1. Deliverable I.4 Balancing -TERRE project- (15th IG meeting, Paris, April 7th 2014)

  2. Context • ACER’s 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 4 1 1- Request time 3 2 5 6 2- Preparation period Full Activation time (from LFC-R) 3- Ramping period Characteristics defined by the WG AS 4- Min & max bid size 5- Min & max delivery period Full Delivery Period 6- Deactivation period

  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.
