ACER workshop: Advancing electricity network tariff design in the EU

What is it about?
ACER is organising a hybrid workshop in Brussels to discuss how to improve electricity network tariff design across the EU and gather stakeholder input ahead of its 2027 report on network tariff methodologies.
Following the European Commission’s proposal for new network tariff rules (July 2026) and ongoing national reviews of tariff methodologies, the workshop offers an opportunity to exchange views on how to make network tariffs cost-reflective and future-proof.
Why does it matter?
Meeting the EU’s energy and climate goals requires large investment in electricity grids. At the same time, electrification, growing renewable generation and new technologies are changing how grids are used, requiring more flexibility and efficiency.
As the power system and grid use evolve, network tariff design needs to keep pace. How charges are set determines how the costs of operating and developing electricity grids are shared among users and how efficiently networks are used.
Cost-reflective, transparent tariffs send users clear signals of the costs their network use causes, which can depend on where and when the grid is used. This helps to:
- make efficient use of existing infrastructure;
- integrate new technologies; and
- limit costs for users.
Workshop objective
The workshop will bring together regulators, system operators, generation and storage associations, consumer representatives and other stakeholders to discuss:
- time-of-use network charges;
- tariffs for bidirectional network users, focusing on storage; and
- specific tariff regimes for large consumers.
What are the next steps?
Register by Tuesday 17 November 2026 to attend in Brussels. Due to limited capacity, in-person attendance is subject to confirmation.
Participants can also register to attend online (no deadline).
Insights from the workshop will help shape ACER’s 2027 report on network tariff methodologies.
Pre-reading material
Participants are encouraged to read ACER’s 2025 report on network tariff methodologies before the workshop.
