Public consultation
Share your view
ACER consults to give interested stakeholders the opportunity to have a say in issues that affect them.
Your input informs our decisions and build trusts and confidence in the market.
How do we consult?
We have a mix of open "public consultations" and "targeted consultations", where we ask specific questions.
- Public consultations typically take the form of an online survey.
- Targeted consultations are aimed at particular stakeholders (e.g. Transmission System Operators).
We strive for clear and realistic timeframes for input. The duration is decided case-by-case, depending on the complexity of the issue and ACER's legal timelines to reach a decision.
To be transparent and accountable, we:
- Explain in our consultations the objectives, what we would like from you and the next steps.
- Publish all (non-confidential) submissions received. Parties wishing to submit confidential information should do so in accordance with Article 9 of ACER Decision 19/2019.
- Publish the outcome of our consultation and an Evaluation of Responses to explain how the main comments were taken into account.
- Treat confidential information in line with our Data Privacy Notice.
