Alstom Grid Awarded Offshore Platform Substation Contract


A consortium made up of Alstom Grid and WeserWind GmbH Offshore Construction Georgsmarienhutte has been awarded a turnkey construction and grid-connection contract for a self-floating and self-installing, offshore high-voltage substation.

EnBW Erneuerbare Energien GmbH awarded the project to build, install and connect a 155/33 kV substation for EnBW Baltic 2, the company's 80 turbine, 288 MW offshore wind project. The project is located in the German Baltic Sea and is connected via a high-voltage alternate-current connection onshore to 50Hertz Transmission GmbH, the regional transmission service operator.

Scope of supply includes Alstom Grid power transformers, high- and medium-voltage gas-insulated switchgear, auxiliary power supply, substation automation, and protection and control systems for 80 wind turbines. The platform will be equipped with boat landings and a heli-hoist and will be used as a logistics service platform during installation and operation of the offshore wind farm.

WeserWind will construct and deliver the hull, the steel structures and the major part of the secondary equipment required for operation of the platform, and will provide the offshore installation services for the complete substation platform.

Offshore commissioning is scheduled for June 2012.
