Dr. Matthias Lang

Offering extensive entrepreneurial knowledge and long-standing expertise in energy and infrastructure regulatory matters , I head our international Energy and Utilities Sector Group as well as the Infrastructure Group. I am a member of our Commercial and Regulatory and Administrative Practice Group.

I advise our clients on energy, infrastructure, regulatory, state aid and environmental law as well as issues arising from public commercial law. In addition, I have expertise in corporate law, administrative, European and real estate law, as well as standardisation.

With extensive experience in advising clients on all aspects of the German Energiewende and the energy transition more generally, I also advise on national and cross-border energy issues, including both conventional and renewable energy generation and battery storage, oil and gas, planning and permit procedures for power generation, extra-high-voltage lines, hydrogen, gas pipelines and gas storage, electro mobility, as well as energy and other industrial installations. Over the years, I have worked on numerous complex infrastructure, energy efficiency and climate change projects, as well as transactions in regulated industries, including energy, healthcare, transportation, water and chemicals.

I represent our clients before the Federal Network Agency, ministries and other authorities in diverse administrative, regulatory or legislative proceedings, before national and European courts and in arbitration proceedings. Together with my team, I have advised on the transposition of European law, including the implementation of the European Clean Deal and European energy and environmental directives and regulations, including REACh, REMIT and MIFID.

Contributing regularly to legal publications, I write the section on permits for conventional power plants, wind farms, solar parks and the closure of nuclear power plants for the "Berlin Commentary on Energy Law" and the section 'Integration of the German into the European electricity market' in the Pritzsche/Vacha book on German energy law, and cover international company law in the "Beck Online Commentary on the Limited Liability Company Act". I have also published articles on oil and gas law in Germany, prosumer legislation, the digitalisation of the energy transition (including blockchain), state aid to the energy sector, grid expansion and environmental protection in the extra-high-voltage grid, on the permitting regime for HVDC lines, and the Renewable Energy Sources Act (EEG).

I'm the chair of the Energy, Environment, Natural Resources and Infrastructure Law (SEERIL) Section of the International Bar Association. I also sit on the board of the German-American Lawyers' Association (DAJV) for Düsseldorf. Furthermore I often speak at national and international seminars and conferences and teach postgraduate energy law and sustainable mobility courses at Technische Universität Berlin and Freie Universität Berlin.

You'll find me listed in various directories, including 2025 Leaders League, 2024 Best Lawyers/Handelsblatt, 2024 Who's Who Legal Germany and 2024 Who's Who Legal Energy.

Before studying law, I graduated with a degree in economics and worked as a banker.
