The energy storage facility utilises SGRE’s innovative energy storage system which can store up to 30 MWh of energy and boasts maximum scalability at a low investment cost. The pilot facility is currently in its final construction phase with all the main buildings and main components having already been completed. The storage facility, able to hold the daily energy requirements of 1,500 German house holds, is set to be commissioned in 2019.
Scientists from the Institute of Thermo-fluid Dynamics at the Technical University of Hamburg and the energy supplier Hamburg Energie have been involved in the development of the facility and Hamburg Energie is aiming to sell the stored power on the energy markets. Hamburg's municipal energy supplier developed the IT platform to which the storage unit is connected. This has been designed to guarantee maximum possible optimised energy storage usage. The Federal Ministry of Economics and Energy is promoting storage development as part of the Future Energy Solutions project.
With ETES, SGRE has developed a storage facility that reduces the construction and operating costs of larger storage facilities to a fraction of the usual level for battery storage. In commercial use, the technology can store energy at a cost of well below ten euro cents per kilowatt hour.
“We are proud to be able to offer this important technology as a fully functional solution for our customers after just a few years of development work” said Hasan Özdem, Head of Technology Management and Projects at Siemens Gamesa. “A very interesting option of our technology is to convert decommissioned thermal power plants into high-performance storage facilities for renewable energies at a low cost”.
