COUPLING
General overview
-
AS IS > TO BE
NWE
Two separate Market Couplings (CWE & Nordic) linked by a volume coupling (ITVC
organised by EMCC)
Sequential calculation approach
No common algorithm applied
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

NWE DA
It promotes liquidity and
robustness of DA markets
It allows for
optimal usage
of cross-border
capacities
It encourages
the harmonization of market rules
It establishes the
necessary
framework to
enable extensions
NWE is more than the sum of its parts

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

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
Post-coupling Final notification deadline of 15:30 in CWE, CWE-GB and
CWE-Nordic interconnectors

2nd Auction CWE/ GB
48 min
Max. Time /Flexibility to solve technical problems
55min
-
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 thresholds will be introduced: + 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
2nd Auction CWE/ GB

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. 17

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
20
-
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
21
-
Full Decoupling scenario
22
CWE : 4 local PX auctions
Nordic-Baltic Market Splitting
Virtual Capacity is set to Zero
2 local PX 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)

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

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

Partial Decoupling before OBK
GCT (12:00)
34
-
* 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.

LINKED & EXCLUSIVE BLOCK
ORDERS
New Block Order Types
-
Linked Block Orders
Definition: The execution of (a set of) profile block(s) is subject to the
execution of another block
Other standard execution rule apply in full
Use: Allows to explicitly consider technical and economical
constraints
For example, a first block may include the start-up costs of a production facility, and additional blocks comprising fuel costs may be linked to this block
Possibility to design complex linked structures (i.e. families)

Technical plant data
Production cost 50 MW = 65 /MWh Production cost 300 MW = 60
/MWh Marginal cost to increase production
from 50 MW to 300 MW = 59 /MWh Marginal cost to increase from 50
MW to 200 MW = 61 /MWh Marginal cost to increase from 200
MW to 300 MW = 56 /MWh
Bidding strategies Possible bidding strategy 1:
Block 1: Sell 50 MW @ 65 Block 2: Sell 250 MW @ 59
linked to Block 1
Unit is fully accepted if P>60; or 50 MW accepted if P>65
Possible bidding strategy 2:
Block 1: Sell 50 MW @ 65 Block 2: Sell 150 MW @ 61
linked to Block 1
Block 3: Sell 100 MW @ 56 linked to Block 2
Unit is fully accepted if P>60; or 200 MW accepted if P>62; or 50 MW accepted if P>65

Linked Block Orders: global wellfare considered
The unit will also clear if baseload price is 60 P 65!
The algorithm is not sequential, but considers the global wellfare of both blocks.
85
-
Linked Block Orders use cases
Optimise thermal power plants Offer plant using multiple orders, allowing it to run at different
outputs, each reflected by their own cost level
Run one/several hour(s) earlier or later if power prices remain interesting outside of the peak period
Optimise consumption processes Only execute part B of consumption process if part A of
process was started earlier
Or only start A+B when combination does not exceed certain costs
Optimise storage capacity Sell only during peak period if off-peak purchase order has
been accepted and buy/sell combination is in the money
86
-
Exclusive Block Orders
Definition: Within a set of profile blocks, at most one block can be
accepted
Other standard execution rule apply in full
Use: Allows to propose for trading different production patterns For example, a specific production plant can be offered
at a low price for baseload production, at a medim price for peak load production >at a high price for super peak load production but can only be executed once
High price order
1 3 5 7 9 11 13 15 17 19 21 23
Medium price order
1 3 5 7 9 11 13 15 17 19 21 23
Low price order
1 3 5 7 9 11 13 15 17 19 21 23
-
Exclusive Block Orders
Optimise thermal power plants Similar to using Linked Block Orders
Optimise combined heat & power installations Heat demand with flexible timing, or some heat buffer Flexibility might allow to produce heat & power when power
prices are highest, using several exclusive production profiles
Optimise demand side management Case: End user can stop consumption, but only if DAM prices
> 500 /MWh and for max 2 hours/day Program load shedding on the DAM on the most expensive
hours (and only of threshold is reached), using a combination of exclusive blocks of 2 hours Block 1: hours 1 & 2, Block 2: hours 2 & 3,

Benefits of Smart Orders
Smarter orders give more flexibility when introducing orders for the auction
Better reflecting technical constraints of generation units
E.g. no partial clearing at non-cost reflective price levels, lower PRB frequency (plant offered in smaller blocks),
Easier bidding, less operational work
Result: better asset optimization (generation + consumption)
Better price formation
More robust against uncertainties faced when making day-ahead price forecasts

* 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
