One of the largest European energy storage systems will be built in Germany
Eco Stor has outlined its intentions to construct a substantial battery energy storage system (BESS) in Saxony-Anhalt, Germany, with an impressive capacity of 300 megawatts (MW) and a storage capacity of 600 megawatt-hours (MWh). This project is poised to stand as one of the most significant undertakings of its kind within Europe.
Georg Gallmetzer, the Managing Director of Eco Stor, has officially announced that the project is slated for completion in 2025 and will demand an investment of approximately 250 million euros ($280 million). The construction phase is scheduled to commence in the coming year.
Project configuration
The project’s blueprint encompasses six ECO STOR ES-50C units, with each unit possessing a capacity of 50 megawatts (MW) and 100 megawatt-hours (MWh) of storage. Each block incorporates a 110 kV station, along with 16 containers designated for inverters and transformers, in addition to 32 boxes dedicated to lithium-ion batteries.
The project’s development phase has progressed to the extent that a building permit application has been formally submitted. A decision on this application is anticipated in the forthcoming weeks.
Eco Store activities in Germany
Eco Stor has recently achieved the successful implementation and launch of two energy storage projects in Germany. The initial project was carried out for the investment firm Obton, with a capacity of 27.6 MW and a storage capacity of 32.4 MWh. The second project was conducted for the energy company Verbund, boasting a capacity of 20.7 MW and a corresponding storage capacity of 20.7 MWh.
Comparing this upcoming venture in Saxony-Anhalt, it’s worth noting that it might surpass the current largest Battery Energy Storage System (BESS) in Germany, which is the 72 MW facility in Werne, owned by energy company RWE. RWE is concurrently engaged in two projects – one with a capacity of 80 MW and a storage capacity of 84 MWh, and another with a capacity of 140 MW and a storage capacity of 151 MWh, both situated in North Rhine-Westphalia. These projects are projected to be operational by 2024.
According to data provided by Eco Stor, Germany presently boasts over 1 gigawatt (GW) of large-scale energy storage. In Europe, the most substantial BESS project in terms of energy capacity is a British system developed by Harmony Energy, with an impressive capacity of 196 MWh.
