NWE DAY-AHEAD PRICE

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

13 Transmission System Operators

4 Power Exchanges

Approx. 50 systems involved

Approx. 150 interfaces

40 serviced interconnectors

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

48 min

16

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

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)

22

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

NL, BE and APX UK markets isolated

EPEX CWE internal borders and IFA, DK-DE, DE-SE

NPS (Nordic) Nordic area, NorNed, DE-DK, DE-SE

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

Entire region All markets isolated (but Nordic markets internally coupled)

33




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:


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,

88

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

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.
