Article 6c 4.

Member States without underground gas storage facilities may provide incentives or financial compensation to market participants or transmission system operators, as relevant, for the shortfall in revenues, or for costs incurred by them, as a result of their compliance with their storage obligations pursuant to this Article, where such a shortfall or such costs cannot be covered by revenue, in order to ensure compliance with their obligation to store gas in other Member States pursuant to paragraph 1 or the implementation of the burden-sharing mechanism. If the incentive or financial compensation is financed through a levy, that levy shall not be applied to cross-border interconnection points.
