EEE Energy Market 2025: What Changes for Operators in Norway, Iceland and Liechtenstein

Key data

Energy operators acting in the markets of Norway, Iceland and Liechtenstein must take into account a regulatory change that has been in force since December 5, 2025. Decision 288/2025 of the EEE Joint Committee updates the Annex IV (Energy) of the Agreement on the European Economic Area, integrating new EU energy legislation into the legal framework of these three countries.

The practical result is that the rules of the European energy market now apply uniformly in the 30 countries of the EEA, including the three that are not EU members. For companies with a presence in those territories, this eliminates regulatory asymmetries and reduces uncertainty in operational planning.

What does this regulation establish?

The Agreement on the European Economic Area (EEA) extends the EU internal market to Norway, Iceland and Liechtenstein. For this market to function coherently, the EEA Joint Committee periodically updates the annexes of the Agreement to incorporate EU legislation as it is approved.

The Annex IV of the EEA Agreement is the one that contains the applicable regulations on energy. With Decision 288/2025, adopted on December 5, 2025, new EU energy rules are incorporated into Annex IV that must be applied by Norway, Iceland and Liechtenstein.

This mechanism ensures that energy operators acting in the EEA do not face divergent regulatory frameworks depending on the country in which they operate. The update is part of the ongoing process of reviewing the EEA Agreement.

Economic and operational impact

The direct impact of this decision is regulatory and compliance-related, not financial in terms of new fees or specific sanctions contained in the text. However, it has concrete operational consequences for affected companies:

• Regulatory homogeneity: Operators acting in Norway, Iceland or Liechtenstein now operate under the same energy rules as in EU countries, which simplifies regulatory management in multi-country environments.
• Regulatory predictability: Alignment with EU legislation reduces the risk of future regulatory divergences in these markets, facilitating medium and long-term planning.
• Review of contracts and operational frameworks: The incorporation of new EU energy legislation into Annex IV may require reviewing contracts, licenses or operational procedures that were referenced to the previous framework.
• Market access opportunity: Regulatory alignment can facilitate the entry of Spanish operators into Norwegian, Icelandic or Liechtenstein energy markets by reducing barriers to regulatory adaptation.

Who does it affect?

This decision primarily affects:

• Energy operators with activity in Norway, Iceland or Liechtenstein (production, distribution, marketing of energy).
• Spanish companies with subsidiaries or contracts in those three EEA countries not belonging to the EU.
• Legal and regulatory advisors serving clients with operations in EEA markets.
• CFOs and compliance officers of energy groups with international presence in the EEA area.
• Companies in the process of expansion towards energy markets in northern Europe that need to know the applicable regulatory framework.

Companies that operate exclusively in Spain or in other EU countries are not directly affected by this decision, unless they have contractual relationships with operators established in the three countries mentioned.

Practical example

A Spanish energy sector company that has a subsidiary in Norway dedicated to energy marketing must verify whether the new EU energy legislation incorporated into Annex IV of the EEA Agreement modifies any of the requirements applicable to its activity in that market.

Before Decision 288/2025, the subsidiary operated under the Annex IV framework in its previous version. With the update in force since December 5, 2025, the applicable regulatory framework already includes the new EU energy legislation. If that legislation introduces new reporting obligations, technical requirements or market access conditions, the Norwegian subsidiary must comply with them on the same terms as an operator established in an EU country.

The practical benefit is that the legal and compliance team of the Spanish parent company can apply the same regulatory knowledge to manage both operations in Spain and those of the Norwegian subsidiary, without needing to analyze completely different regulatory frameworks.

What should companies do now?

1. Identify if you have energy activity in Norway, Iceland or Liechtenstein. If you operate in any of these three countries, this decision directly affects you and you must review its content.
2. Consult the full text of Decision 288/2025 to identify what EU energy legislation has been incorporated into Annex IV and whether any of those rules introduce new obligations for your activity.
3. Review contracts, licenses and operational procedures that were referenced to the previous framework of Annex IV of the EEA Agreement, to verify if they require updating.
4. Coordinate with the local legal team in Norway, Iceland or Liechtenstein to confirm the transposition or application deadlines for the new rules incorporated.
5. Update the internal regulatory map if your company has a system for monitoring applicable regulations in EEA markets, incorporating the changes resulting from this decision.
