The largest battery storage facility in the Czech Republic has a capacity of 4 MW and a capacity of 2.5 MWh. For C-Energy, it provides a range of functionalities, in particular increasing the flexibility of existing power generators to further enhance the ability to secure favorable energy prices. The average Czech household could power its electrical equipment for up to 1 year using installed batteries, and an electric car would cover 12,500 km per charge (approx. Distance from Planá nad Lužnicí to Phnom Penh, Cambodia). Battery storage uses Siemens SIESTORAGE technology.
“Installing batteries in a C-Energy power supply is a typical example of how modern technology can penetrate traditional areas of industry. Connecting batteries to a fossil energy source is a relatively new idea, but it brings many benefits and I believe that this technical solution will soon be applied to other sources in the Czech Republic, ” said Karel Havlícek , Minister of Industry and Trade of the Czech Republic.
Battery storage C-Energy is the largest in the Czech Republic. In Europe, however, there are larger ones, for example, the 13 MW MW repository in Bavarian Pfreimd is equipped with SIESTORAGE technology. The uniqueness of the C-Energy Planá battery storage application lies mainly in its connection to the existing power supply, where the battery provides high performance at a relatively low capacity, while effectively optimizing the coverage of peak energy consumption of C-Energy customers and providing performance balance services.
“Similar battery applications around the world can not do without external power and no additional functionality. In comparison with them, the uniqueness of the solution at C-Energy Planá stands out. Like other sources, our solution can provide superior performance services. At the same time, however, it improves the functionality of the power plant itself and brings a significant increase in the security of electricity supply for our clients connected to the local C-Energy Planá distribution system, ” said Libor Doležal , CEO of C-Energy Planá.
The storage is based on Siemens Energy Storage (SIESTORAGE) technology from Siemens. It includes control systems, Li-Ion battery cells, switchboards, inverters / converters, transformers, self-supply and other auxiliary systems. The whole storage facility is located in the outdoor environment in three containers. It has a guaranteed output of 4 MW and a usable minimum capacity of 2.5 MWh for 10 years.
“The shift from central to decentralized energy is undeniable. This trend is primarily determined by the customer and is reflected both in the mix of production resources and in networks, especially distribution networks. Battery is an element that will play an increasing role. The reasons are both technical and commercial, as evidenced by the installation of the largest SIESTORAGE storage facility in C-Energy, ” said Tomáš Hüner , Director of Siemens Smart Infrastructure .
C-Energy expects the main benefits of batteries in deliveries to the local distribution system in Planá nad Lužnicí (LDS) industrial zone and in enhancing the range of performance balance services. Another important feature is the ability of the repository to provide the first voltage to start from the dark C-Energy power supply and subsequently to ensure the islands operation of the power supply for LDS even to a larger extent, if different causes of the collapse of the grid and overall power failure in the area .
The storage control system is connected to the existing C-Energy power supply control system. The batteries will be recharged both from electricity generators and from a 520 kWp photovoltaic power plant, which was built on otherwise unusable land in the area of ??the energy source.
“The use of a large-capacity battery here in Planá shows in full the spectrum of applications of this groundbreaking technology. I greatly appreciate the growing interest in batteries in the heating industry, industry and, increasingly, in the construction of recharging infrastructure for electric vehicles. However, the state should not abandon the full legalization of accumulation so that it can be used with renewable energy sources, ” concludes Jan Fousek , Executive Director of the Association for Accumulation and Batteries. |
