Siemens is to supply a battery storage system to Vulkan Energiewirtschaft Oderbrücke GmbH to provide black start capabilities for a gas turbine at a power plant in Eisenhüttenstadt, Germany.
Siemens Low and Medium Voltage Division is supplying a Siestorage lithium-ion battery system that has been designed for Vulkan to provide 2.8 MVA and a capacity of 720 kWh.
The Eisenhüttenstadt blast furnace gas-fired power plant supplies a steel mill with re-start capabilities for the gas turbine after a power outage. The motor draws current from the battery storage system to ensure reliable current. The gas turbine starting motor is 400kW so the 720kWh ESS can accommodate the black starting.
Additionally, in the case of a power outage, the plant provides back-up heat and electricity to the steel mill.
This will be the second Siemens Siestorage in operation, the first being a 500kWh system in Italy that provides frequency and voltage stability to photovoltaic plants.
