Where do we come from and where are we now?
Initial work on the Nordic FB methodology started as a voluntary and joint effort of
all Nordic TSOs in 2012/13.
With the CACM entering into force in 2015, the Nordic FB project was altered into
the Nordic CCM project being a CACM (and FCA) GL implementation project,
addressing all the legal requirements

Where do we come from and where are we now?
- FB simulations -
Prototype tools and a prototype CGM have been developed in order to perform an impact
assessment (presented in the supporting document that is published on the Nordic RSC
website: link) and with the objective to run a weekly simulation process
FB capacity calculation and allocation simulations have been performed and are available on the
Nordic RSC website for download (link)
17 weeks in 2016
11 weeks in 2017
The prototype-based CGM and thereby the prototype simulation process - is error-prone
The CGM is built up from individual SCADA models created by each TSO, and merged centrally
The fact that the SCADA systems were upgraded or replaced at most TSOs stalled the prototype CGM process
to a large extent in 2018/19
The prototype simulation process facilitated a learning-by-doing, that is reflected in the IT
specifications of the industrial tool that is currently being implemented
The main focus is now on starting the simulations using the industrial tools and industrial
CGMs, during the so-called internal and external parallel runs that are scheduled to start in
2020
Where do we come from and where are we now?

Guideline on Capacity Allocation and Congestion Management
(CACM GL)
Article 20.2:
No later than 10 months after the approval of the proposal for a capacity calculation region in
accordance with Article 15(1), all TSOs in each capacity calculation region shall submit a proposal for
a common coordinated capacity calculation methodology within the respective region.’

Guideline on Capacity Allocation and Congestion Management
(CACM GL)
‘There are two permissible approaches when calculating cross-zonal capacity: flow-based or based on
coordinated net transmission capacity. The flow-based approach should be used as a primary approach
for day-ahead and intraday capacity calculation where cross-zonal capacity between bidding zones is
highly interdependent.’
‘The coordinated net transmission capacity approach should only be applied in regions where cross-zonal
capacity is less interdependent and it can be shown that the flow-based approach would not bring added
value.’

The maximum export from A to
another bidding area amounts
1500 MW:
An example three-node network:
NTCs
A B
C
NTC(A>B) = 750 MW
NTC(B>C) = 750 MWNTC(A>C) = 750 MW
Given the maximum export of bidding area A,
the TSO needs to split the 1500 MW export
capability into two bilateral exchanges, for
example:
NTC(A>B) = 750 MW
NTC(A>C) = 750 MW
There are in principle an infinite number of NTC
solutions; it is a choice which one to select
NTCs are determined by the TSOs to facilitate the market while
safeguarding the grid
A NTC limits a commercial exchange between two bidding areas
NTCs are simultaneously feasible
An example three-node network:
NTCs and physical flows
The following commercial exchanges are feasible given the NTCs:
A>C = 750 MW
A>B = 750 MW

In FB capacity split is not a choice of the TSO, but is market
driven (at the time of allocation)
In principle, FB offers more trading opportunities with the
same level of security of supply

Advantages of the FB approach
In FB capacity split is not a choice of the TSO, but is market driven (at the time of allocation)
More efficient and flexible use of the grid
FB offers more trading opportunities with the same level of security of supply
More price convergence / smaller price differences
Higher social welfare
Income redistribution: Less congestion income and more producer and consumer surplus
FB offers the possibility to have the DC cables efficiently embedded in the allocation mechanism,
by providing a fair competition for the use of the scarce AC capacity
Flow-based market coupling provides an efficient allocation mechanism in which all exchanges
that are subject to the allocation mechanism compete with one another for the use of the scarce
capacity

Advanced Hybrid Coupling is applied on all DC links and AC connections to other CCRs
In this way, they compete for the scarce capacity in the AC grid like any other commercial exchange

Background1
Recap of the FB methodology
FB simulations: setup
FB simulations are being performed by the project, based on
Prototype CGMs
Prototype tooling to perform the DA FB capacity calculation
The so-called NEMO’s Simulation Facility to simulate the SDAC using the FB constraints and
actual historical order books
With the implementation ongoing at the Nordic RSC, gradually, elements in this process will
be replaced by more robust data and IT modules

FB simulations: socioeconomic welfare gains
The following results are for weeks 1-6 and 8-12, 2017
and compare the market outcomes with FB and with
historical NTCs.
The graphs show the difference between the day-
ahead socioeconomic welfare (SEW) with FB and with
historical NTCs
Day-ahead SEW = producer surplus + consumer
surplus + congestion income
Structural congestions such as West Coast corridor and
export limitations in Norway dealt with in a more
efficient way with flowbased:
No need to limit capacities ex ante.
Instead: full capacities + critical network
elements given to the market => capacity
allocated in the market in a more efficient way.
Week 1: 4 January, 03.00: A windy night
Example of the West-Coast Corridor
A lot of wind to be exported
from DK/GE to the Nordics
With NTC, ex-ante
limitations on DK1->SE3 and
DK2->SE4 due to West Coast
corridor
With FB, capacity allocation
in the market considers
directly the West Coast
corridor without need for
limitations.
Note that the limitations GE-
>SE4 are due to limitations
on the German side.

Original Nordic TSO LT CCM proposal: CNTC
In the FCA GL, the CNTC methodology is
the default capacity calculation approach
The Nordic TSOs proposed a CNTC LT
capacity calculation methodology, where
A linearized security domain (i.e. FB domain is
assessed) first, and
A CNTC domain is extracted from that
As there are many CNTC domains that can
be extracted from the FB domain, the
CNTC extraction is based on an
optimization

Original Nordic TSO LT CCM proposal: CNTC
CNTC characteristics
CNTC is a “limited / not-so-detailed” way
to represent grid limitations
All CNTC capacities are simultaneously
feasible
Due to these characteristics, the fear
is that the CNTC domain, that is
extracted from a FB domain, is too
restrictive (compared to todays
values)
Therefore, relaxation of the FB
domain is considered for the CNTC
extraction
This comes at a price: the CNTC domain
sticks” out of the FB domain and may
cause an operational risk.

ACER’s decision on the Nordic LT CCM: FB
On May 15, Nordic NRAs referred the LT CCM to ACER
NRAs have a different interpretation of “what constitutes a CNTC and what
constitutes a FB methodology
ACER amended the LT CCM, and iterated with TSOs and NRAs in weekly
conference calls
ACER decided on October 30 (Decision 16/2019) to approve the Nordic LT
CCM (see embedded documents FYI)
ACER decided on a FB Nordic LT CCM:
ACER’s decision on the Nordic LT CCM: FB
some highlights
ACER decision
FB
FB with ATC extraction as intermediate solution
until a FB LT allocation is supported by the service
provider (the terminology CNTC is not used)
Optimization-based CNTC extraction (unchanged)
Dynamic constraints as allocation constraints
This means that the dynamic analysis can be
performed by the TSO
Advanced hybrid coupling is part of the CCM
(unchanged)
Publication of data has been extended and
aligned to that of the ACER decision on the Core
DA/ID CCM
Original Nordic TSO proposal
CNTC
A linearized security domain (i.e. FB domain is
assessed) first, and a CNTC domain is extracted
from that
Optimization-based CNTC extraction
Dynamic constraints as CNEs (as so-called PTCs:
Power Transfer Corridors)
This means that the dynamic analysis can be
performed by the TSO
Advanced hybrid coupling is part of the CCM
Publication of data as in the Nordic DA/ID CCM
ACER’s decision on the Nordic LT CCM: FB
some highlights
Amendment of the LT CCM / actions required within 18 months after implementation
of the methodology
Amend the CCM by including the method for assessing the economic efficiency of
including internal network elements (combined with the relevant contingencies) in
the long-term capacity calculation.
Amend the CCM - in case the concerned Nordic TSOs cannot find and implement a
more efficient solution than the applied combined dynamic constraint - by:
(a) the technical and legal justification for the need to continue using the combined
dynamic constraint indicating the underlying operational security limits and why they
cannot be transformed efficiently into maximum flow on specific CNECs;
(b) a detailed methodology to calculate the values of the combined dynamic
constraints.
Amend the CCM by further harmonizing the generation shift key methodology.
Amend the CCM by including the description and definition of the functions used in
the ATC extraction.
Amendment process of the DA/ID CCM
The “Version 2” DA/ID CCM - being the amended DA/ID
CCM following the RfA from DUR, EI, and EV has been
approved by the three NRAs
The Nordic TSOs are in the process of amending the DA/ID
CCM (“Version 3”), in line with the LT CCM
This amended DA/ID CCM is to replace fully the earlier two
versions
The public consultation of this amended DA/ID CCM is
expected to start in January 2020
Amendment process of the DA/ID CCM
Some highlights
FB ID, with ATC extraction as intermediate solution until a
FB ID allocation is supported by the service provider
Publication of data as proposed by ACER for the LT CCM
Dynamic constraints as allocation constraints
18 months after DA/ID CCM implementation, amend the
CCM by including the method for assessing the economic
efficiency of including internal network elements
Economic efficiency test and operational security test for
the application RAs will be removed in the light of the
previous bullet, and the Regulation 943/2019
