Germany: Wirsol Roof Solutions wants to implement a battery storage system with a capacity of 13 megawatt hours

Large storage systems on the rise in Germany Wirsol Roof Solutions wants to implement a battery storage system with a capacity of 13.41 megawatt hours in Thuringia. Eco Stor will start next year with a major project in which 600 megawatt hours of storage capacity will be built up in Saxony-Anhalt. In Förderstedt, Eco Stor intends to build a storage power plant with a capacity of 600 megawatt hours from next year. Germany needs storage for the energy transition, not only the small photovoltaic home storage, but also large storage. The market for the latter is currently rather difficult, and expansion is proceeding rather slowly. But this could change in the short term, as the current reports from Wirsol Roof Solutions and Eco Stor indicate. Together with partners from the Wirth Group, Wirsol wants to implement a large-scale storage facility in Ohrdruf, Thuringia. It is a battery container solution with an output of 10.35 megawatts and a capacity of 13.41 megawatt hours. The storage location covers an area of 670 square meters. The large-scale storage facility was connected not far from a substation operated by Thüringer Energienetze, according to general contractor Wirsol Roof Solutions. The grid connection takes place on the property, with the transfer station already being set up. According to project manager Christian Jochemich from W Power GmbH, the battery storage will be integrated into the 20 kilovolt medium voltage level of the network operator. The Wirth subsidiary, together with Profine Energy, owns and operates the large-scale storage facility. The commissioning of the storage system is planned for the first quarter of 2024. The battery storage in Ohrdruf is to be used to compensate for fluctuations in the power grid. In addition, it should improve the integration of renewable energies and increase the efficiency of the energy system. The companies stated that it would be used with a "multi-use mode of operation". This could generate revenue from ancillary services such as primary control reserve (FCR) and secondary control reserve (aFRR). The electricity trading of the battery storage will take place via intraday and day-ahead trading as well as financial transactions and order book trades. Eco Stor plans 600 megawatt hours storage power plant The large-scale storage facility that Eco Stor wants to build in Saxony-Anhalt, more precisely in Förderstedt in the Salzland district, has a completely different dimension from next year. It could become Europe's largest battery power plant. The Bavarian company wants to set up a system with a storage capacity of 300 megawatts and a storage capacity of 600 megawatt hours on an area of eight hectares in the immediate vicinity of a substation. According to the current plans, a total of six "ECO STOR ES-50C" blocks are to be built. According to EcoStor, each block consists of 16 container stations for inverters and transformers and 32 container stations for the lithium-ion batteries. The company estimates the total investment to be around 250 million euros, which Ecor Stor intends to raise together with other financing partners. After completion of the storage power plant, around half a million households could be supplied with electricity for two hours. The plan is to link the storage facility in real time to the various marketplaces where electricity from photovoltaic and wind power plants is traded. “Electricity prices are becoming increasingly weather-sensitive. With increasing production of wind and solar power, more and larger storage systems are needed and their balancing effect,” said Eco Stor Managing Director Georg Gallmetzer. Eco Stor is also calling for a change in policy so that communities can benefit from the trade tax revenue from storage power plants. This is already the case with photovoltaic power plants and wind farms. There, the local communities receive 90 percent of the trade tax revenue. Eco Stor also wants this for battery storage. The regulation in the Annual Tax Act 2023 should be adjusted for this. The large-scale storage facility is to be charged wholesale in times of low electricity prices. These are usually times with large feed-in quantities from photovoltaic systems or wind farms. Discharging should take place when electricity prices are high, meaning that only a small proportion of renewable energy is available. At the same time, the storage system ensures security of supply. "Power grids can transport energy over long distances, but not over time," Gallmetzer continues. "This requires storage that temporarily stores renewable electricity and in times of darkness or when there is no wind
