Draft Cross-regional roadmap for Capacity Calculation

This ongoing draft discusses the cross-regional roadmap for capacity calculation, focusing on the transition from the Available Transfer Capacity (ATC) method to a preferred Flow-based (FB) allocation method in interconnected grids. It highlights the need for coordination among Transmission System Operators (TSOs) across regions, detailing project milestones and necessary requirements for successful implementation by 2014. The document serves as a foundation for discussions among stakeholders, addressing horizontal issues, market coupling, and the strategic paths forward for capacity calculation in various regions.

Presentation Transcript

  1. Draft Cross-regional roadmap for Capacity Calculation Still work in progress, for discussion 27 June 2011

  2. Agenda • Background • Overview of current regional road maps • Cross-regional roadmap for capacity calculation • Project milestones • Horizontal issues and open questions

  3. Background (1) Target model (FG CACM) by 2014 TSOs can define either Available Transfer Capacity (ATC) or Flow-based (FB) method Flow-based allocation method considered to be preferred to ATC method in highly meshed grids / highly interdependent grids for short term capacity calculation Interdependence with Market Coupling method and algorithm

  4. Background (2) Cross-regional roadmap is based on regional work plans 2011-2014 AESAG work on roadmap FG CACM

  5. Background (3) • Coordination between TSOs will be key • TSOs of different regions will need coordination regarding their capacity calculation in all cases: when two regions both use the same method (FB or ATC) but also in cases where one region conducts FB and the other region ATC calculations • Different paths possible to get to FB method • Path 1: MC before FB • Path 2: FB before MC

  6. Background (4) • Agreed requirements to be fulfilled in order for a region to switch to FB: • Coordinated principles and data • No decrease in Security of the System • Increase in Social welfare • Enough time to adapt for market participants • Work on Flow-Based Capacity Calculation methods should not delay Market Coupling

  7. Overview of currentregionalroadmaps

  8. Cross regional roadmap for capacity calculation • TSOs regularly inform all NRAs and other stakeholders on all implementation steps 8

  9. Project milestones - CWE • Decision on path 1 already made in CWE region • Implementation foreseen: Q2 2013 • Improved cooperation and information exchange on capacity calculation with CEE and other relevant regions

  10. Project milestones - CEE • Decision on which path (1 or 2) to follow in CEE region at the latest* by Q1 2012 • * This decision could be anticipated if Hungary, Czech Republic and Slovakia are committed to join the NWE market coupling by the end of 2012 (cf. the cross-regional roadmap for market coupling)

  11. Project milestones - other regions • SWE, FUI and Baltic Regions already decided to stick to the ATC approach • CSE, NE and SEE: decision expected at the latest in Q3 2012
