Our group company GTS is the transmission system operator of the national gas grid in the Netherlands, as defined in the Dutch Gas Act. Being the national transmission system operator, GTS was under an obligation to comply with the requirements from the Dutch Gas Act and the rules on proper financial management (BFBN) throughout 2025. The ratios from the BFBN rules do not apply if a recognised credit rating agency has given the transmission system operator an ‘investment grade’ creditworthiness rating. In 2025, GTS was assigned a private investment grade credit rating by a recognised credit rating agency, meaning that GTS met the financial management requirements for transmission system operators in 2025.
As of 1 January 2026, the Dutch Gas Act ceased to apply and gave way to the new Dutch Energy Act, which requires transmission system operators to demonstrate their creditworthiness by means of an investment grade credit rating assigned by a recognised credit rating agency. If a transmission system operator is unable to show a level of creditworthiness that meets the requirements, they must notify ACM immediately, prepare a recovery plan and will not be allowed to pay dividend or other kind of distribution to its shareholders.
