In energy law, Thomas represents our clients in administrative and judicial proceedings relating, inter alia, to the expansion of the offshore grid, the provision of grid system services (redispatch) and claims under the Freedom of Information Act. In energy-related M&A transactions he most recently advised EPH on the acquisition of the Schkopau power plant (2020), NAFTA on the acquisition of German underground gas storage facilities from DEA (2019) and CVC on the sale of ista (2017).
