Alstom offshore substation Baltic 2

Alstom has commissioned the Alternate Current (AC) offshore substation for Energie Baden-Württemberg (EnBW) in the 288MW Baltic 2 offshore wind power facility in Germany.

Located 32km north to the island of Rügen in the Baltic Sea, the facility was officially commissioned by EnBW towards the end of last month.

Equipped with 80 Siemens SWT-3.6-120 wind turbines, the plant has the capacity to meet power requirements of around 340,000 households.

Alstom’s high-voltage offshore substation will support energy transmission through a 150kV submarine cable, from the wind turbines to the onshore connection point of the network in Bentwisch.

Under the turnkey contract awarded by EnBW, Alstom was responsible for the technical development, design and supply of the electrical components, platform construction, transport and offshore installation of the substation.

Alstom Grid Central, eastern Europe and Russia region vice-president Gerhard Seyrling said: "The integration of renewable energies plays a key role in the successful implementation of the energy transition.

"Equipped with 80 Siemens SWT-3.6-120 wind turbines, the plant has the capacity to meet power requirements of around 340,000 households."

"With the installation of the offshore substation for EnBW Baltic 2, Alstom has made an important contribution to this transition in Germany thanks to its technical expertise and leadership in connecting offshore wind farms to the grid.

"The project opens up another direct access point for wind energy in Germany."

Alstom’s GIS substations have been installed within the buoyant and self-erecting Baltic 2 platform.

While the platform’s design has facilitated transportation and installation of the offshore substation, its closed layout has been developed to protect the electrical components from an oceanic climate.
