The Wartburg storage facility in Eisenach is currently one of the largest battery storage facilities in Europe. In future, it will contribute to the integration of renewable energies into the electricity grid by balancing out the fluctuating feed-in of renewable energy and ensuring grid stability. Built and operated by Smart Power GmbH, the large-scale storage facility with a battery voltage of 1500 volts has a connected load of 60 MW and a capacity of 67 MWh. SMA is supplying 20 turnkey system solutions with battery inverters and coordinated medium-voltage technology for the project. With their grid-forming properties, they also contribute to securing the power supply in the event of a power failure.
One of the challenges in building the large storage facility was to take up as little space as possible. To achieve this, the plant was built in concrete and additional space was created on the 3.5-metre-high roof for the inverters, which weigh around 350 tons in total. Although the solid concrete construction method is more time-consuming and cost-intensive compared to a container concept, it offers numerous advantages in terms of the service life of the building. Following its planned completion in Q3/22, the storage facility will be used to provide PRL (primary control power), VNE (avoided grid charges) and intraday trading.
The SMA Sunny Central Storage UP battery inverters with grid-forming functions enable more efficient and flexible planning for storage power plants with an output of up to 3960 kVA at system voltages of up to 1500 VDC. The wide DC voltage ranges make them compatible with most battery technologies.
