Working Group
Power Markets

About

Established in 2003, the Working Group Power Markets (WG PM) is the longest-standing WG within Europex. Since its inception, it has actively contributed to the development of an integrated European electricity market, particularly in regulation related to cross-border trading and congestion management. Its overarching aim is to support the continued development of an efficient, accessible, liquid, safe and transparent Internal Energy Market in Europe, in which exchanges play a vital role.

WG PM covers organised wholesale electricity trading and related regulatory issues across all timeframes — including forward, day ahead, intraday, balancing and ancillary services markets. It also focuses on 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.
Additionally, the group addresses forward-looking market design topics, with particular focus on the energy sector contribution to decarbonisation efforts. Further, the group works on strategic topics such as market functioning in a high renewables system, energy system integration and renewable electricity certificates (e.g., Guarantees of Origin).

WG PM therefore operates on both the technical and strategic levels. It primarily works through contributing to consultations, publishing position papers and participating in stakeholder groups and other fora. Members raise and respond to concerns linked to initiatives to establish new or amend EU legislation in the field of electricity. These include Network Codes and Guidelines and related methodologies. The WG also maintains close interaction with relevant EU level institutions and key stakeholders.
