Gerstaberg Switching Station: Strengthening Sweden’s Future High‑Speed Rail Network

Converter stations and feeder stations ensure that rail networks receive the correct voltage and frequency, even as traffic intensifies or train weights increase. Mobile and permanent installations provide flexibility, strengthen weak network sections and support international rail corridors with varying technical requirements.

Reliable rail transport depends on dedicated AC and DC power‑supply systems, including converter stations, feeder stations, traction‑power substations and mobile energy‑supply units. These systems enable stable and resilient power delivery for heavy rail, metro, tram and light‑rail networks across Europe.

Smart grid solutions improve network performance by capturing, storing and reusing energy more intelligently. Technologies such as mobile or modular substations, regenerative systems and energy‑storage units help reduce peak loads, increase efficiency and make better use of the existing grid — reducing both costs and environmental impact. An example is Strukton’s Energy Bank (OV energiebank).

Modern energy networks rely on extensive civil engineering works, including the construction of high‑voltage substations, transmission‑line foundations, access roads, cable routes and site preparation for electrical stations. These works form the physical backbone that allows grid operators to expand capacity safely and efficiently.

Expanding the electricity grid is crucial to support increasing demand from renewable energy, electric mobility, gas‑free homes and growing data‑center capacity. A larger and stronger grid ensures reliability, prevents congestion and enables the seamless integration of solar, wind and other sustainable energy sources.
