5. LNG system operators, natural gas storage system operators, hydrogen terminal operators and hydrogen storage operators shall make public the amount of natural gas or hydrogen in each LNG facility, natural gas storage facility, hydrogen storage facility and hydrogen terminal, or group of storage facilities if that corresponds to the way in which the access is offered to system users, inflows and outflows, and the available LNG facility, natural gas storage facility, hydrogen storage facility and hydrogen terminal capacities, including for those facilities exempted from third-party access. That information shall also be communicated to the transmission system operator or to the hydrogen network operator for hydrogen storage and terminals, which shall make it public on an aggregated level per system or subsystem defined by the relevant points. The information shall be updated at least daily.
Where a natural gas or hydrogen storage facility user is the only user of a natural gas storage facility or hydrogen storage facility, the natural gas or hydrogen storage system user may submit to the regulatory authority a reasoned request for confidential treatment of the data referred to in the first subparagraph. Where the regulatory authority comes to the conclusion that such a request is justified, taking into account, in particular, the need to balance the interest of legitimate protection of business secrets, the disclosure of which would negatively affect the overall commercial strategy of the storage user, with the objective of creating competitive internal markets for natural gas and hydrogen, it may allow the natural gas storage system operator or hydrogen storage operator not to make public the data referred to in the first subparagraph, for a duration of up to one year.
The second subparagraph shall apply without prejudice to the obligations referred to in the first subparagraph, unless the aggregated data are identical to the individual natural gas or hydrogen storage system data for which the regulatory authority has approved non-publication.
