Transmission Planning Activities in South-East Europe

entso e a trans european network
ENTSO-E: a trans-European network
  • Established under the Regulation 714/2009
  • Fully operational since July 2009
  • Represents 42 TSOs from 34 countries
    • 525 million customers
    • 828 GW generation capacity
    • 305,000 Km of transmission lines
    • Total demand:3,400 TWh/year
    • Electricity trade volume: 400 TWh/year
  • Replaces former TSO organisations: UCTE, ETSO, NORDEL, UKTSOA, ATSOI, BALTSO
regulation 714 2009 tasks for entso e
Regulation 714/2009 – tasks for ENTSO-E

Article 4: European network of transmission system operators for electricity

Completion and functioning of the internal market in electricity and cross-border trade

Optimal management, coordinated operation and sound technical evolution of the European electricity transmission network

Article 6: Establishment of network codes

Article 8: Tasks of the ENTSO for Electricity

Network codes

Common network operation tools

Non‑binding Community‑wide 10‑year network development plan, including a European generation adequacy outlook, every two years

Work programme, annual report, summer/winter outlooks, monitoring

Full implementation until March 2011

ENTSO-E operational much earlier because a fully developed IEM and the integration of RES

demand urgent TSO action

Context for the TYNDP

Non binding

Every 2 years


Every year

Regulators check consistency

  • Nat. TYNDPs
  • Existing and forecast supply demand
  • Efficient measures to guarantee adequacy & SoS
  • Indicate main transmission infrastructure to be built
  • Based on reasonable assumptions about evolution of generation
  • Supply consumption and exchanges
  • Generation adequacy outlook 5 yr up to 15yr ( 2025!)
  • modelling integrated networks
  • Scenario development
  • Assessment of resilience
  • Based on reasonable needs of system users
  • Identify investments gaps
  • Review barriers to increase cross border capacities arising from approval procedures

Build on nat. gen. adequacy outlooks and invest. plans

grid development challenges
Grid development - challenges
  • Legal and Regulatory frameworks
      • accelerate/simplify permitting procedures while maintaining checks and balances
      • adequate financing given the major effort induced by RES
  • Involve all relevant stakeholders into information channeling in order to alleviate uncertainties (generation location, policy implications)
  • Social acceptance of transmission infrastructure
tyndp public consultation
TYNDP - public consultation
  • Public consultation 1st March – 10th April
      • More than 100 attendees at workshop, 21 written answers
  • Acknowledgements
  • Shared sense of urgency
  • Synthetic picture of congestion
      • Project clustering, improved transfer capability
  • Achievement of EU 2020 targets
  • Integration of transmission projects
      • Also from non-ENTSO-E members
first tyndp a pilot but process has already started
First TYNDP a Pilot, but process has already started

EC preparation of the Energy Infrastructure Package: ENTSO-E invited to provide additional input to assist the assessment of the Policy

Compare TYNDP planning scenarios with publicly available scenarios related to the EU2020 targets.

“What if” planning scenarios should converge today to 2020 scenarios.

More RES? Less Fossil? Where?

Propose measures to accelerate permitting procedures in Europe.

Visualize main enhancements in NTCs

But, focus on forward-looking indicators for market integration.

Evolving from reliable networks designed for optimization of generation resources and power demand requirements…

… towards a transmission & distribution networks implementing EU energy & climate policies and maximizing welfare.

Main challenge for all network operators

  • Electricity Directive 96/92/EC (1999)
  • 3rd Legislative Package for the Internal Market in electricity (2009)
  • Directive for Renewable Energy Sources (2009)

Integrated concept

Taking all aspects into account

Involving all major stakeholders in the process

Huge investment budget

In-depth study necessary to avoid stranded investments

Modular approach

Gaining know-how along the learning curve, realization should proceed step-by-step

In line with EIP, ENTSO-E takes the lead in a 3-year in-depth study project to finally develop by end 2014

the Modular Development Plan for a

Pan-European Electricity Highways System

The Strategy: Sustainable solutions for the big challenges ahead need in-depth analysis before investment decisions.

the overall entso e mission
The overall ENTSO-E Mission
  • Identify studies and elaborate a “Roadmap towards a pan-European power system 2050” with special focus on a 2050 supergrid as an overall guideline for the supergrid conceptual phase
  • Perform consultations and closely collaborate with EC, stakeholders and the public for achieving a common understanding of supergrid issues
  • Manage ENTSO-E supergrid studies and address all essential results at EU level
  • Develop strategies for increasing the social acceptance for grid development measures as a precondition for the realization of the supergrid concept.
  • Develop strategies for increasing the readiness of decisionmakers to support and promote the idea of a supergrid as an answer to European energy needs.
New Context: The EIP Blueprint*
  • EIP blueprint recommendations:
  • Following key actions are necessary to prepare European Electricity Highways:
  • In line with the conclusions of Bucharest Forum (06/2009):
  • Initiate dedicated work on the Electricity Highways, in the framework of
  • the Florence Forum, to structure the work carried out by all stakeholders
  • Organisationby the European Commission and ENTSO-E and bringing together all relevant stakeholders
