European gas and power trading

Trading activity and volumes across European gas and power markets are increasing, with a growing number of participants entering both financial and physical markets.

These markets offer significant opportunities, but they also present distinct regulatory, legal and operational challenges. Market participants must navigate registration and licensing requirements, tax and customs obligations, operational and IT infrastructure, and a combination of pan-European and country-level rules.

Our European gas and power trading team helps financial institutions, commodity traders and other market participants understand these requirements, access the relevant markets and infrastructure, and manage the risks associated with trading across Europe.

Why European energy markets require a tailored approach

European gas and power markets continue to develop against a backdrop of:

  • increased trading activity and volumes

  • a growing number of financial services firms entering the market

  • geopolitical events, conflicts and sanctions

  • climatic variables

  • government intervention

  • electrification and changing consumption patterns

  • growing energy demand associated with AI and data centres

  • increased market integration

  • the use of complex approaches to pricing and market access.

Unlike the US energy markets, European markets are highly fragmented. Participants may need to consider pan-European legislation alongside local registration, licensing, tax, customs and operational requirements. The applicable rules and market-entry processes are not fully harmonised between jurisdictions.

Our team helps clients identify an appropriate route to market and understand the obligations, documentation and risks associated with their chosen model.
