No actions have been completed yet with regard to this topic.​

The European Union Agency for the Cooperation of Energy Regulators (ACER) and the Council of European Energy Regulators (CEER) have published today a joint paper including recommendations ahead of the upcoming revision of  the Guidelines for trans-European energy infrastructure Regulation (TEN-E Regulation).

The proposals focus on infrastructure development governance, scope and process. The Europe​an Commission intends to review and to revise the Regulation before the end of 2020 as one of the initiat​​ives of the European Green Deal and it is currently consulting with stakeholders and regulators. This paper serves as a response to the public consultation​ as well. 

Based on the extensive experience on the benefits and shortfalls of the current TEN-E Regulation, national regulatory authorities (NRAs) and ACER propose legislative changes to improve the planning and implementation of electricity and gas infrastructure, aiming to make it streamlined, focused on sustainability and neutral both in terms of technology and potential conflict of interest. ​

In the paper, ACER and CEER p​​​​​​​​​​ropose specific recommendations in the following three areas: 

• ​governance of infrastructure development
• scope of principles for Projects of Common Interest
• TEN-E processes.​​​

The European Commission is developing legislative proposals (as part of the Grids Package) to improve and simplify the current legal framework. This includes the revision and simplification of the 2022 Trans-European Energy Networks Regulation (TEN-E Regulation), a key framework for the European energy infrastructure development. 

On 19 September 2025, ACER published a position paper on improving and simplifying the legal framework on European grids.

As the Regulations do not foresee approvals by more than one regulatory authority, the Agency will not be asked to adopt decisions when regulatory authorities cannot agree on terms, conditions and methodologies.​

RfG Implementation​

The Agency monitors the procedure of granting derogations from one or more provisions of the RfG Regulation.

The relevant regulatory authority decides which power-generating modules should be classified as an emerging technology. Any regulatory authority of the relevant synchronous area may request a prior opinion from the Agency, which shall be issued within three months after receiving the request. The decision of the relevant regulatory authority shall then take into account the Agency's opinion.

All regulatory authorities of a synchronous area may also decide in a coordinated manner to withdraw a classification as an emerging technology. Also in this case, the regulatory authorities of the synchronous area concerned may request a prior opinion from the Agency, which shall be issued within three months. Where applicable, the coordinated decision of the regulatory authorities shall take into account ACER's opinion.

Find out more on how national regulatory authorities implemented the transitional arrangements for emerging technologies in the Implementation Monitoring Report of the Network Code on Requirements for Grid Connection of Generators. 

The accumulated sales of power-generating modules classified as emerging technology are also made available by the national regulatory authorities every two months.

The Agency monitors the procedure of granting derogations from one or more provisions of the DCC Regulation. The Agency may issue a reasoned recommendation to a regulatory authority to revoke a derogation, in case justification is missing.​

The Agency monitors the procedure of granting derogations from one or more provisions of the HVD​C Regulation. The Agency may issue a reasoned recommendation to a regulatory authority to revoke a derogation, in case justification is missing.​​

Transmission System Operators have to provide non-discriminatory access to their infrastructure and offer the same service and contractual conditions to other market players (third party access). 

Regulatory authorities may grant exe​​​mptions for new interconnections in strict circumstances:

• the investment must enhance competition in the electricity supply

• the level of risk attached to the investment is such, that the investment would not take place without the exemption

• the interconnection must be owned by a legally separate firm from the TSO in whose system it will be built;

• the users of the interconnector must pay for it

• the costs of the interconnection cannot be financed through charges for using the linked transmission or distribution systems

• the exemption does not harm the competition or the efficient functioning of the market or the regulated system.​

Regulatory authorities receiving a request for exemption should decide within six months. When NRAs fail to agree, or upon their joint request, ACER becomes responsible for adopting such decision.​

​A copy of every exemption request needs to be transmitted to the European Commission and to ACER on receipt.

Within two months, ACER can provide an opinion to the regulatory authorities involved.

If a decision is taken, this must be notified  by the NRAs to the European Commission, together with all relevant information.

The decision shall be notified, without delay by the concerned regulatory authorities (or by ACER where the decision is taken by ACER), to the Commission, together with all the relevant information with respect to the decision.

The Commission may request to amend or withdraw the decision to grant an exemption. The exemption expires if the construction of the interconnector has not started within two years yet or the interconnector has not become operational within five years. The exemption may be extended if the delay is due to major obstacles beyond the control of the project promoter.​
