On December 16, 2025, the Department of Energy and Resources Law at the Scandinavian Institute of Maritime Law, UiO, organised a seminar on legal aspects of energy sharing and peer-to-peer (P2P) electricity trading. The seminar gathered a group of researchers and practitioners from several European jurisdictions.
After professor Catherine Banet had welcomed the participants and introduced the legal questions investigated in the Privacy preserving Transactive Energy Management (PriTEM)-project, the first half of the seminar saw presentations from four external speakers.
First out was Professor Lucila de Almeida from Nova School of Law, Lisbon, who presented an overview of the EU regulatory framework regarding energy sharing and P2P trading as well as divergences and convergences in national transpositions. Job Svens (CEO at Joining OBjectives for Sustainable, World ENergy Solutions) then described the regulatory development and practical experiences of energy sharing in the Netherlands before Mari Holen Christensen (head of Section for Energy Market Law, Norwegian Energy Regulatory Authority) presented the ongoing work of the Norwegian authorities on the regulation of energy sharing within the same property and for commercial and industrial areas across properties. Thereafter, Dr. Hamish George Ritchie, (postdoc at University of Copenhagen, Faculty of Law) gave his reflections on contractual governance and regulatory barriers to P2P energy trading.
During the second part of the seminar, the five research assistants from the Department of Energy and Resources Law presented their master’s theses in the PriTEM project. Hrithik Verma explained how ownership to energy data is regulated in EU and Norwegian law. Connor Wilkinson accounted for his findings regarding the possibility to trade energy on peer-to-peer basis between EU states. Oliver Stavik discussed price sitting mechanisms in the European energy market regulation. Johannes Yngve presented his study on whether energy sharing activities should affect network tariffs. Finally, Eszter Pataki-Csontos elaborated on how tax incentives can support peer-to-peer energy trading within EU energy law.
The contributions to this seminar will be published in a special issue of MarIus in the spring of 2026.
