In a bid to overcome the problems of fluctuation in the renewable power, especially solar energy, Siemens AG, the global powerhouse in electronics and electrical engineering, has developed an energy-storage system that can act as a buffer in electrical power grids.
With its modular power storage system called as ‘Siestorage’, Siemens aims to provide a buffer against short-term fluctuations in output from renewable energy sources. Such fluctuations can last for seconds or several minutes long. The Siestorage battery is based on lithium-ion rechargeable battery technology and fits into a normal shipping container. In its big layout it stores 500 KWh of electricity.
Siestorage starts off at 16kWh and can be extended to a capacity of 2 MWh. The 500 KWh can power up to 50 households and fits into an average-sized shipping container or any equivalent space with ease and offer as a power output of 8MW.
Siemens has already installed a 500 kWh system with Italy’s largest energy company Enel. The utility is using the power storage to help integrate solar PV plants and an electric car charging station into the grid. Enel will also study how well the system can handle a controlled restart of a grid after a complete blackout.
