The battery-based 11.7-MW/34-MWh energy storage system is expected to be able to store enough energy to power 5,000 homes for a day.
Battery manufacturer Fluence and photovoltaic system builder Münch Energie are planning to build a combined photovoltaic-battery storage system. In the process, a 34-MW photovoltaic plant is to be built in the Merseburg district of Beuna (Saxony-Anhalt). Siemens subsidiary Fluence is then to supplement this with a storage system, as the companies made public in a joint announcement. The storage capacity should be sufficient to supply 5,000 households with electricity for one day.
After its planned completion in April 2023, the project is to be connected directly to the power grid via a specially built substation, which will enable participation in the secondary reserve market.
The project had been awarded the contract in the innovation tender of the Federal Network Agency in May 2022. According to Section 39 of the Renewable Energy Sources Act (EEG 2021), this is intended to promote "particularly grid- or system-serving technical solutions that prove to be efficient in the technology-neutral competitive process." The invitation to tender in April 2022 attracted 45 bids, 43 of which were successful. The successful bidders will receive a fixed market premium for the renewable energy they produce.
