Ten-Year Network Development Plan (TYNDP) 2020

Closed 4 Jan 2021

Opened 6 Nov 2020


ENTSO-E’s 10-year network development plan (TYNDP) is the pan-European electricity infrastructure development plan. It looks at the future power system in its entirety and at how power links and storage can be used to make the energy transition happen in a cost-effective and secure way.

The TYNDP 2020 has been developed with the expertise of 35 European TSOs.

With this consultation, ENTSO-E asks for feedback on:

- the TYNDP 2020 report and Highlights

- the Project sheets, showing how 180 electricity transmission and storage projects can contribute to the European energy transition;

- the power system needs study, investigating where new solutions for electricity exchange are needed to reach decarbonisation targets and keep security and costs under control in the 2030 and 2040 horizons. We present needs at pan-European, regional and country levels:

- Insight reports on operational challengesinertia and smart sector integration.

- TYNDP 2020 CBA Implementation GuidelineImplementation Guideline on redispatch assessment and Implementation Guideline on project-level indicators


Why your views matter

  • The future is developed by all of us and there does not exist one clearly-defined path to reach it - developing suitable grid solutions that stand all possibilites is key;
  • Planning and building the transmission infrastructure requires all of us - public acceptance impeds 25% of pan-European projects to realise on time;
  • Present the information in a format and at a level that can be used not only by the experts but by all of us.


The TYNDP reports and project sheets presented are drafts for consultation. They will only be considered final after the comments received are assessed, and ACER has provided a formal opinion. All information, including on any individual project, must be considered preliminary and is subject to change in the final version.

As per ENTSO-E's rules on consultations, a consultation document can only be modified during the consultation period in order to correct mistakes originated during the layout phase, which takes place after the internal document validation decisions are taken. ENTSO-E cannot accept to update a consultation document due to mistakes originating before the final validation of the document, be it the responsibility of ENTSO-E, its members or any other party.

What happens next

After the end of the consultation period ENTSO-E wil assess the comments received and edit the draft TYNDP 2020 as needed. The draft TYNDP 2020 will then be submitted to ACER for Opinion. After reception of ACER's Opinion, the TYNDP 2020 will be finalised and published on ENTSO-E's website.
