Power Markets


The Working Group Power Markets, established in 2003, is the longest standing WG within Europex. Since its creation, WG PM has focused on making an active contribution to the development of an integrated European electricity market, including regulation linked to cross-border trading and congestion management. Its aim is the further development of an efficient, accessible, liquid, safe and transparent Internal Energy Market in Europe, in which exchanges play a vital role.

The working scope of WG PM covers organised wholesale electricity trading and related regulatory issues in forward, day ahead, intraday, balancing and ancillary services markets, as well as the development of efficient demand-side flexibility markets. Through their activities, members work to ensure that robust market design principles are upheld and that the benefits of coupled, organised power markets are recognised. Forward-looking market design topics are also addressed. With a focus on the energy sector contribution to decarbonisation efforts, the group also works on strategic topics such as market functioning in a high renewables system, energy system integration and renewable electricity certificates (e.g., GOs).

WG PM therefore acts on both the technical and strategic level, the group primarily works through contributing to consultations, publishing position papers and participating in stakeholder groups and other fora. Members are able to raise and respond to concerns linked to initiatives to establish new or amend EU legislation in the field of electricity, including Networks Codes and Guidelines and related methodologies. The WG also interacts closely with relevant EU level institutions and other stakeholders.
