Trans-European Networks for Energy

The Trans-European Networks for Energy (TEN-E) is a policy that is focused on linking the energy infrastructure of EU countries. As part of the policy, nine priority corridors and three priority thematic areas have been identified.

The EU helps countries in priority corridors and priority thematic areas to work together to develop better connected energy networks, and provides funding for new energy infrastructure.

Priority corridors

The nine priority corridors cover different geographic regions in the field of electricity, gas and oil infrastructure.  EU support for development in these corridors will connect regions currently isolated from European energy markets, strengthen existing cross-border interconnections, and help integrate renewable energy.

Electricity corridors

North Seas offshore grid (NSOG): Integrated offshore electricity grid development and related interconnectors in the North Sea, Irish Sea, English Channel, Baltic Sea and neighbouring waters to transport electricity from renewable offshore energy sources to centres of consumption and storage and to increase cross-border electricity exchange.

North-south electricity interconnections in western Europe (NSI West Electricity): Interconnections between EU countries in this region and with the Mediterranean area including the Iberian peninsula, in particular to integrate electricity from renewable energy sources and reinforce internal grid infrastructures to promote market integration in the region.

North-south electricity interconnections in central eastern and south eastern Europe (NSI East Electricity): Interconnections and internal lines in north-south and east-west directions to complete the EU internal energy market and integrate renewable energy sources.

Baltic Energy Market Interconnection Plan in electricity (BEMIP Electricity): Interconnections between Member States in the Baltic region and the strengthening of internal grid infrastructure, to end the energy isolation of the Baltic States and to foster market integration; this includes working towards the integration of renewable energy in the region.

Gas corridors

North-south gas interconnections in Western Europe (NSI West Gas): Gas infrastructure for north-south gas flows in western Europe to further diversify routes of supply and for increasing short-term gas deliverability.

North-south gas interconnections in central eastern and south eastern Europe (NSI East Gas): Gas infrastructure for regional connections between and within the Baltic Sea region, Adriatic and Aegean Seas, eastern Mediterranean Sea and Black Sea, and for enhancing diversification and security of gas supply.

Southern Gas Corridor (SGC): Infrastructure for the transmission of gas from the Caspian Basin, Central Asia, Middle East and eastern Mediterranean Basin to the EU to enhance diversification of gas supply.

Baltic Energy Market Interconnection Plan in gas (BEMIP Gas): Gas infrastructure to end the isolation of the three Baltic States and Finland and their dependency on a single supplier, to reinforce internal grid infrastructures, and to increase diversification and security of supplies in the Baltic Sea region.

Oil corridor

Oil supply connections in central eastern Europe (OSC): interoperability of the oil pipeline network in central eastern Europe to increase security of supply and reduce environmental risks.

Priority thematic areas 

The three priority thematic areas, which relate to the entire EU, include smart grids deployment, electricity highways, and a cross-border carbon dioxide network.

Smart grids deployment: increase deployment of smart grids to help integrate renewable energy and allow consumers to better regulate their energy consumption

Electricity highways: construction of electricity highways – large grids that allow electricity to be transported over long distances across Europe (e.g. from wind farms in the North and Baltic Seas to storage facilities in Scandinavia and the Alps)

Cross-border carbon dioxide network: development of transport infrastructure for captured CO2 through dedicated thematic groups.

Revision of the TEN-E policy

The TEN-E Regulation (EU) 347/2013 will be reviewed in 2020 to ensure consistency with the climate neutrality objective of the European Green Deal.

The European Commission launched a consultation (open until 13 July 2020), seeking input to the revision of the TEN-E guidelines from specialists, stakeholders and the public.

A series of  stakeholder webinars will be organised in June 2020, to provide details on the ongoing evaluation process and to exchange views on any aspects related to it 

  • TEN-E Infrastructure categories to ensure consistency with the climate neutrality objectives of the Green Deal and digitalisation priorities
  • Selection procedure and criteria for projects of common interest (PCIs)
  • Regulatory toolbox and criteria for the Connecting Europe Facility (CEF) financial assistance
  • PCI Implementation: Permitting, monitoring and involvement of stakeholders
