- Period
- 1 January 2020 – May 2025

- Responsibility
- Chair of the management board
- Action
- Led a group whose grid companies run about 196,000 km of power lines and 37,000 km of gas network, with about 11,000 employees (company figures, 2024)
- Result
- Its subsidiary Westnetz carried out H2HoWi in Holzwickede (October 2022 – end 2023), the first conversion of a public gas line in Germany to 100% hydrogen
- Significance
- Operational experience of the distribution grids that connect most renewable plants
- Limitations
- Company results cannot be attributed to her personally. The role is the main basis of conflict-of-interest criticism since 2025, and she was listed in Westenergie's lobby-register entry until she became minister.
