2 General overview NWE DAY-AHEAD PRICE COUPLING

3 General principles OPERATIONAL PRINCIPLES & POSSIBLE SCENARIOS

4 Price Coupling Process General term for ATC and/or FB parameters used = CZCs : Cross Zonal Capacities 4

5 NWE Business Process 10:30 CZCs and allocation constraints submitted to PCR 12:00 Orderbooks closure Global Preliminary PX Confirmation 12:55 Global Final Confirmation Publication 12:55 14:00 Nominations CZCs and allocation constraints submission and integration Final Confirmation of the results Market Coupling Results and Scheduled Exchanges transfer Trading confirmation and scheduled exchanges notification PCR process: CZCs and allocation constraints process Orderbook processing PMB calculation Preliminary confirmation process Final confirmation process 5

6 PCR Process Timings for NWE Normal process 55 minutes 12:00 OBK GCT 12:00 12:10 Check of OBK and sending to PMB 12:10 12:27 Calculation 12:28 12:41 Preliminary PX validation 12:42 Publication of preliminary results (incl. market clearing price) to the market and in parallel sending of these preliminary results for final confirmation/approval to the TSOs 12:42 12:54 Final TSO validation 12:55 Publication of Final Results (incl. market clearing price) Start of Notification Process 6

7 Process is delayed Target Time Latest Time to Start an IC Partial Coupling/Full Decoupling Deadline TIME Normal Procedure Normal procedures can still apply after target time Backup procedure can apply before the target time Backup procedures Fallback procedures can apply before fallback time Fallback procedures Decoupling preparation decoupling 7

8 Process delayed assumptions Pre-coupling Deadline to solve incidents with Network Data (CZCs) publication is 11:45 CET Coupling Time allowance for technical problem solving 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 Max. Time /Flexibility to solve technical problems 55min 2 nd Auction CWE/ GB 48 min Post-coupling Final notification deadline of 15:30 in CWE, CWE-GB and CWE-Nordic interconnectors 8

9 Second Auction 2 nd Auction CWE/ GB 48 min 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: EUR/MWh and -150 EUR/MWh In GB thresholds will be introduced: 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 9

10 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 full decoupling deadline when NWE is coupled. 10

11 Fallback procedures Target Time Latest Time to Start an IC Partial Coupling/Full Decoupling Deadline TIME Normal Procedure Normal procedures can still apply after target time Backup procedure can apply before the target time Backup procedures Fallback procedures can apply before fallback time Fallback procedures Decoupling preparation decoupling 11

12 Fallback procedures Target Time Latest Time to Start an IC Partial Coupling/Full Decoupling Deadline TIME Normal Procedure Normal procedures can still apply after target time Backup procedure can apply before the target time Backup procedures Fallback procedures can apply before fallback time Fallback procedures Decoupling preparation decoupling 12

13 Full Decoupling of NWE 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 13

14 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 14

15 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) 15 15

16 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 16

17 CWE TSO investigation on flexibility of notification deadline impact on procedures Exceptional cases Notification Process 45 min 15:30 15:30 15:30 15:45 Crossborder Notification Process 45 min Generation Notification Process At least 60 min 17

18 PCR PROCESS TIMINGS for NWE 18

19 Full Decoupling before OBK GCT (12:00) OBK GCT = 12:00 Case X10 Full decoupling before Case X11 X10 + delay Case X12 X10 + 2nd Auction CWE Full decoupling 42 min Full decoupling 42 min Full decoupling 42 min Notification Process 60 min Max. Time /Flexibility to solve technical problems 55min* Notification Process 60 min 2 nd Auction CWE/ GB 28 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 full decoupling deadline when NWE is coupled. 19

20 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 fallback solution for these temporary not participating borders / interconnectors NWE parties will try to couple as many borders / interconnectors as possible Partial Decoupling is triggered during the pre-coupling process, at the latest at 11:45 during the coupling process, at the latest at 12:40 20

21 Partial Decoupling Scenario Example : CWE+GB <> Nordic PCR coupling Nordic-Baltic: Market Splitting Shadow Auctions Local matching process PCR matching process 21

22 Partial Decoupling Scenario Example : NorNed PCR coupling Shadow Auctions PCR matching process 22

23 Partial Decoupling Scenario Example : EPEX OBK missing PCR coupling Shadow Auctions PCR matching process Local matching process 23

24 Partial Decoupling Scenario Example: APX NL/Belpex OBK missing PCR coupling Shadow Auctions Local matching process PCR matching process 24

25 Partial Decoupling Scenario Example : no CWE CZCs in PMB PCR coupling Shadow Auctions PCR matching process Local matching process 25

26 Decoupling scenarios Where s the problem What decouples? Resulting configuration APX/Belpex EPEX NPS (Nordic) CWE internal borders (FR-DE, FR-BE, BE-NL, NL-DE) and NorNed and BritNed and GB-GB CWE internal borders and IFA, DK-DE, DE-SE Nordic area, NorNed, DE-DK, DE-SE 26 NL, BE and APX UK markets isolated DE, FR, and BE markets isolated Nordic markets isolated (but internally coupled) N2EX GB-GB, IFA N2EX market isolated CWE TSOs CWE internal borders BE market isolated BritNed BritNed No market isolated NorNed NorNed No market isolated Any other individual interconnector PMB, or problem after 12:20 That interconnector Entire region No market isolated All markets isolated (but Nordic markets internally coupled) 26

27 Partial Decoupling 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 full decoupling deadline when NWE is coupled. 27

28 Partial Decoupling 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. 28
