Market Operation
Planning Data
• Defining data needs to
fulfil regulated tasks
• Using existing standard
developed at European
level (CIM format)
• Defining IT architecture
for data management
• 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
capacity
• Ensuring consistency
between wholesale and
retail market
• Unlocking DSR potential
• One single market

• Project team was launched on data management

• Workshop held on 14 January

• Workshop held on 20 January

• Workshops in 2015 resulted in joint paper:
• General Guidelines for Reinforcing the cooperation between TSOs And DSOs
Roles and responsibilities
Example of TSO/DSO cooperation : Balancing
Page 9
• 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
• Assess network capacity regarding balancing offers
• Close coordination on activating offers that might cause congestions
Close to real time
• Close coordination in handling offers that might cause congestions
• Several options are possible for implementing this step
Balancing markets: Market Design Initiative should complement, not overlap with, the Balancing Guidelines (*)
Page 10 (*) one of the EU Grid Codes
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
• 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

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
