Enhancing TSO/DSO cooperation
• Ensuring consistency
between wholesale and
retail market
• Unlocking DSR potential
• One single market

• Defining data needs to
fulfil regulated tasks
• Using existing standard
developed at European
level (CIM format)
• Defining IT architecture
for data management
Data

Planning
• Defining solutions for
observability &
controllability
• Active power management
actions impacting balancing
and congestion in
transmission should be
overseen by TSOs
• Redefine roles of TSOs and
DSOs
• Enhancing the information
exchange for planning
• Coordinating the
assessment of connection

Example of TSO/DSO cooperation : Balancing
•
TSOs might increasingly need to make use of flexibility on the distribution grid to
reduce imbalances.
•
Flexibility activation can cause congestions (active power and voltage) within the
distribution grid.
•
In order to prevent these congestions, close coordination between TSO/DSO is
required:
Long-Medium term
•Assess network capacity
regarding flexibility pools
•Inform the Balancing
Service Providers of
possible limitations due to
network constraints
Day-ahead/Intraday
Close to real time
• Assess network capacity
regarding balancing
offers
• Close coordination in
handling offers that might
cause congestions
• Close coordination on
activating offers that
might cause congestions
• Several options are
possible for implementing
this step

The EB GL defines elements and processes to be
harmonised for integrated European balancing
markets:
•Two-step approach to European Balancing market via
Coordinated Balancing Areas
•Four processes (IN, aFRR, mFRR, RR)
•Standard Products
•Reservation of cross zonal capacity
•TSO-TSO model for procurement of balancing services
•Single Common Merit Order List
•Settlement

(*) one of the EU Grid Codes
• Prices should reflect power system scarcities and
cost-relevant factors such as adequacy, resilience
and location.
• Member States to avoid legal price caps to and to
promote acceptance of scarcity pricing in all
markets
• EC to introduce balance responsibility for RES and
remove mandatory priority dispatch
• ENTSO-E and ACER to propose new AS and system
services markets (e.g. reactive power, transient and
dynamic stability, inertia, etc.) to keep the power
system stable and reliable at all times
• Enable RES participation to provide balancing and
ancillary services compatibly with system needs,
product specifications
Market Design Initiative
Balancing Guideline
Balancing markets: Market Design Initiative should complement, not overlap
with, the Balancing Guidelines (*)

Effective day-ahead and intraday markets for RES integration
Full and timely implementation of the Capacity Allocation and Congestion
Management guidelines (CACM)
Ensure customers are free to access all relevant markets and enable aggregators’
participation
ACER and the National regulatory agencies should put full financial balance responsibility on
all market participants to expose market parties to system adequacy price signals
ID Gate Cloure Time should allow market participants’ to adjust their schedules as closely as
possible to real time while respecting the time required for guaranteeing system security
To improve the investment signal while mitigating the risks for market participants, new risk
hedging products should be introduced
