Wiesbaden breaks ground on €39m Hölderlinstrasse substation

Utility grid subsidiary sw netz broke ground on a new substation on Hölderlinstrasse on 15 July: a €39m investment with two 63 MVA transformers to secure long-term supply for the city centre and government district (roughly 15,000–20,000 households and businesses). Construction partners are Schüssler-Plan and Implenia; commissioning is planned for early 2031. Groundbreaking on 15 Jul 2026. The date is a placeholder: only early 2031 is given, so the end of the first quarter is used.
