The legal foundation for the development of a national public charging infrastructure was established by the Law of 7 August 2012, amending the modified Law of 1 August 2007 on the organization of the electricity market. It defines the responsibilities of network operators and sets the organisational principles for implementing this infrastructure. It also serves as the legal basis for the Grand-Ducal Regulation of 3 December 2015, which outlines the technical specifications, functionalities, number of charging points, deployment schedule, and general rollout framework.

In line with EU Directive 2019/944, transposed into Luxembourg law, distribution system operators are no longer permitted to own, develop, manage or operate public charging stations — except under strictly defined conditions. As such, the amended Electricity Market Law provides that the management and operation of the Chargy/SuperChargy network must be entrusted to a single concessionaire.

The State has therefore granted a seven-year concession for the operation of the public charging infrastructure to the temporary association charge@lux, composed of Electris Luxembourg S.A., Cube 4T8 S.à r.l., and Socom S.A. This group was designated as the concessionaire by joint decision of the distribution system operators and approved by the Luxembourg Regulatory Institute (ILR) in its decision ILR/E25/11 of 13 May 2025.
