  3. General overview NWE Day-Ahead Price Coupling

  4. AS IS > TO BE • Two separate Market Couplings (CWE & Nordic) linked by a volume coupling (ITVC organised by EMCC) • Sequential calculation approach • No common algorithm applied NWE • Full coupling with GB • One single price coupling based on a single calculation • One single common algorithm to allow for a sound and robust price formation

  5. NWE – Driving European Market Integration „NWE ismorethanthesumofitsparts“ It promotes liquidity and robustness of DA markets It allows for optimal usageof cross-border capacities It establishes the necessary framework to enable extensions NWE DA It encouragesthe harmonization of market rules

  6. NWE – Behind the scenes Partiesinvolved • 13 Transmission System Operators • 4 Power Exchanges Systems & interfaces • Approx. 50 systemsinvolved • Approx. 150 interfaces • 40 servicedinterconnectors • 30 biddingzones

  7. NWE - Interconnectors FerroSkan EstLink Skagerak Kontiscan DK1-DE NorNed Baltic SwePol BritNed Kontek IFA

  8. Price Coupling Process • General term for ATC and/or FB parameters used = CZCs : Cross ZonalCapacities

  9. PCR : Price Coupling of Regions

  10. Potential integration of losses on DC cables • Activation of losses on a specific interconnector is subject to approval of relevant national NRAs

  11. General principles Operational principles & possible scenarios

  16. Process delayed – assumptions • Pre-coupling • Deadline to solve incidents with Network Data (CZCs) publication is 11:45 CET • Coupling • Time allowance for technical problemsolving up to 55 min • Time allowance for special market procedures such as handling of curtailment situations or price threshold reached via a second auction used by CWE PXs or the NPS-applied regulated routines that include peak load capacity (production/load) reserves activation. • Deadline for final Market Results is 13:50 CET • Post-coupling • Final notification deadline of 15:30 in CWE, CWE-GB and CWE-Nordic interconnectors Max. Time /Flexibility to solve technical problems 55min 2nd Auction CWE/ GB 48 min

  17. 2nd Auction CWE/ GB 48 min Second Auction • A Second Auction is triggered in case at least one of the CWE/GB prices reach or exceed the predefined price thresholds • The routine consists in • Reopening the PXs order books for 10 minutes to give the Market Participants the opportunity to modify their bids in order to improve the market situation • Execution of a second calculation with the new Order Data • The thresholds to trigger a 2nd auction in CWE remain the same: • + 500 EUR/MWh and -150 EUR/MWh • In GB thresholdswillbeintroduced: • + 500 GBP/MWh and -150 GBP/MWh • In case the prices still reach the thresholds after the Second Auction calculation, no additional Second Auction will be triggered

  18. PCR PROCESS TIMINGS for NWE • * This is the maximum time which could be used to solve a technical problem in order to avoid a decoupling. If the technical problem is resolved in less than 55 min than the next processes will start earlier. • ** the Second Auction in CWE / GB is a single process taking 48 minutes. • *** the Special Procedure for the Nordics is an iterative process which will run the number of times necessary taking into the 13.50 full decoupling deadline when NWE is coupled.

  21. Full Decoupling of NWE (1) • Internally in CWE and for the CWE – Nordic interconnectors (except Baltic Cable): • Shadow auctions organized by CASC will be held and results published • The 3 PXs within CWE will reopen the order books (20 min) and perform local DA spot market calculations without using cross border capacities • The notification deadline of 15.30 is applicable for the notification by market parties of utilization of Explicit Capacity bought in Shadow Auctions • Fallback for Baltic cable : capacity goes back to the cable owner • In GB • Shadow auctions organized by RTE/NGIC are applicable for FR/GB border only (IFA interconnector), this consists of daily explicit auctions • Capacity of virtual interconnector set to zero • The 2 PXs will reopen the order books (APX UK 15 min) and perform local DA spot market calculations without using cross border capacities • Fallback for BritNed: capacity goes to intraday • For the Nordic – Baltic area including the link with Poland • Shadow auctions on 3 CWE-Nordic links • Re-opening of NPS order books • Price coupling will be performed by NPS utilizing the cross border capacities within this region

  22. Shadow Auctions • Bids submitted through the Shadow Auctions interface at CASC.EU are default bids : • They are valid for every day of the year, for a specific border, direction and an hourly period (Volume in MW and a Price in €/MWh) • Participants can update their default bids at any time before the freezing of the database when Shadow Auctions are run • Description in “Harmonised Auction Rules for CWE, CSE and CH” • Possibility to register only for Shadow Auctions, with a ‘lighter’ status: “Participant to Shadow Auctions Only" • Market Participants need to submit a nomination towards the respective TSOs by the notification deadline of 15.30

  23. Full Decoupling scenario CWE : 4 local PX auctions Nordic-Baltic Market Splitting Virtual Capacity is set to Zero 2 local PX auctions Shadow Auctions “Local” matching process In case of full decoupling the processes are local • Communication in case of fallback is organized locally (different info, different timings) 23

  24. CWE TSO investigate flexibility of notification deadline • The CWE TSOs and 50 Hertz have agreed upon a joint target solution for the deadlines for submitting the different schedules towards the TSOs available as of Go-Live of the Price Coupling in the NWE region • Taken into account that it is important for the TSOs to receive data of good quality, the TSOs agreed to extend the deadline for submitting generation schedules in the very rare cases of specific fallback situations to a later time than 15:30 • In these extraordinary situations, all CWE TSOs and 50 Hertz will extend the deadline for submitting generation schedules until at least 15:45. Some TSOs can extend this deadline even beyond 15:45 depending on local market rules • This means that market participants have at least 60 minutes for the submission of generation schedules

  25. CWE TSO investigation on flexibility of notification deadline – impact on procedures Exceptional cases Notification Process 45 min 15:30 15:30 Crossborder Notification Process 45 min Generation Notification Process At least 60 min 15:30 15:45

  26. PCR PROCESS TIMINGS for NWE

  27. Full decoupling before OBK GCT (12:00) Case X12 Case X10 Case X11 X10 + delay Full decoupling before 12.00 X10 + 2nd Auction CWE OBK GCT = 12:00 Full decoupling 42 min Full decoupling 42 min Full decoupling 42 min Publication of prelimi- nary results =12:42 2nd Auction CWE/ GB 28 min** Notification Process 60 min Max. Time /Flexibility to solve technical problems 55min* Notification Process 60 min Notification Process 60 min Final Notification deadline =15:30 which applies to: Internal CWE, CWE-GB and CWE-Nordic interconnectors • * This is the maximum time which could be used to solve a technical problem in order to avoid a decoupling. If the technical problem is resolved in less than 55 min than the next processes will start earlier. • ** the Second Auction in CWE / GB is a single process taking 48 minutes. • *** the Special Procedure for the Nordics is an iterative process which will run the number of times necessary taking into the 13.50 full decoupling deadline when NWE is coupled.

  28. Partial (De)coupling within NWE • Any scenario where one or more bidding areas and/or interconnectors are temporary not participating in NWE Market Coupling while the remaining bidding areas/interconnectors still participate in NWE Market Coupling • The CZCs for the decoupled borders / interconnectors will be allocated via the fall back solution for these temporary not participating borders / interconnectors • NWE parties will try to couple as many borders / interconnectors as possible • Partial coupling is triggered • during the pre-coupling process, at the latest at 11:45 • during the coupling process, at the latest at 12:40

  29. Partial Coupling ScenarioExample : CWE+GB <> Nordic PCR coupling Nordic-Baltic: Market Splitting Shadow Auctions “Local” matching process PCR matching process 29

  30. Partial Coupling ScenarioExample : NorNed PCR coupling Shadow Auctions PCR matching process 30

  31. Partial Coupling ScenarioExample : EPEX OBK missing PCR coupling Shadow Auctions PCR matching process “Local” matching process 31

  32. Partial Coupling ScenarioExample: APX NL/Belpex OBK missing PCR coupling Shadow Auctions “Local” matching process 32

  33. Partial Coupling ScenarioExample : no CWE CZCs in PMB PCR coupling Shadow Auctions PCR matching process 33

  34. Decoupling scenarios 34

  35. Partial Coupling before OBK GCT (12:00) • * This is the maximum time which could be used to solve a technical problem in order to avoid a decoupling. If the technical problem is resolved in less than 55 min than the next processes will start earlier. • ** the Second Auction in CWE / GB is a single process taking 48 minutes. • *** the Special Procedure for the Nordics is an iterative process which will run the number of times necessary taking into the 13.50 full decoupling deadline when NWE is coupled.

  36. Partial Coupling before OBK GCT (12:00) Partial coupling followed by Full Decoupling + Special Routine Nordics • * In case X6b, the NPS special procedure, being an iterative process, may take the same timeframe as when all markets are still coupled, but this is not relevant in a full decoupling since Nordic and Baltic TSOs do not impose a nomination deadline, but instead NPS can take as long time as needed to finish the Price Calculation and subsequent notifications can be submitted (updated) by NPS and market parties to relevant TSOs until about 1 hour before delivery hour.
