Agency for cooperation between EU energy regulators

Agency for cooperation between EU energy regulators


Regulation (EC) No 713/2009 — establishing an Agency for the Cooperation of Energy Regulators



It establishes an Agency for the Cooperation of Energy Regulators (ACER)* (the agency), its mission and tasks, organised in annual work programmes.

The agency complements and coordinates, at EU level, the work of national energy regulators.

It plays a central role in developing EU-wide network and market rules for electricity and gas within the EU’s overall energy policy objectives.


The agency:

issues non-binding opinions and recommendations to transmission system operators*, regulatory authorities, the European Parliament, the Council and the European Commission;

takes binding individual decisions in specific cases and under certain conditions on cross-border infrastructure matters;

submits draft guidelines for use by the Commission as the basis for drawing up network codes (rules);

provides a framework within which national regulatory authorities can cooperate;

coordinates regional and cross-border infrastructure initiatives in areas such as allocating capacity and levying charges on users;

monitors the EU’s electricity and natural gas markets, in particular retail prices and access to the network, including electricity from renewable energy sources;

is managed by a director whose initial appointment is for 5 years — the director prepares the annual work programme for the following year and may establish working groups to provide advice on the agency’s regulatory activities;

may create expert groups to provide ad hoc advice on the development of regulatory policy;

has a budget funded by an EU subsidy, fees, voluntary national contributions and legacies, donations or grants;

may welcome non-EU countries’ participation, under certain conditions, in its work.

In 2011, the agency received additional tasks under Regulation (EU) No 1227/2011 (known as REMIT — regulation on energy market integrity and transparency). This aims to increase the transparency and stability of EU energy markets and to tackle insider trading and market manipulation.

In 2013, Regulation (EU) No 347/2013 on guidelines for trans-European energy infrastructure gave the agency a further role in designating and monitoring projects of common interest.

The agency may set up expert groups on an ad hoc basis to provide it with policy development support. There are currently 3 expert groups which focus on:


ACER, an EU agency, was created by the third energy package to further progress towards completion of the internal energy market both for electricity and for natural gas.

The agency was officially launched in March 2011 and has its seat in Ljubljana, Slovenia.


* Energy regulators: bodies appointed by EU countries to ensure the proper operation of their energy markets, i.e. that energy suppliers meet their obligations and that consumers are supplied with a reliable service at a fair price.

* Transmission system operator (TSO): an entity that transports energy, such as natural gas or electricity, either nationally or regionally, using fixed infrastructure.
