Saft has supplied its Uptimax nickel battery systems for E.ON’s Amrumbank West offshore wind farm.
Saft has provided a total of 80 Saft Uptimax battery systems – one for each turbine. In the event of an interruption to the main power supply, the batteries are designed to deliver peak power for essential safety systems for an initial period of eight hours, followed by a further 88 hours of low power. Each battery is rated at 24V and has energy storage capacity of 150Ah or 390Ah.
The batteries have been built into the modular transition sections of the wind turbine towers, which integrate the structural base section and electrical systems.
The systems were delivered to Engie Fabricom by Belgian company Benning, the power systems supplier for the project.
“E.ON’s Project team has identified that Saft Uptimax is the only battery system that would meet the stringent technical requirements for Amrumbank West,” said Volker Drescher , Saft’s Germany Sales Manager for Industrial Standby batteries.
