Lot LOT-0001: RegioSpeicher Mosbach - EPC - Engineering, procurement and construction (EPC) of a lithium-ion battery storage facility with 10 MW of active power consumption
Preliminary Scope of Work: The project comprises the implementation of a turnkey 10 MW / 20 MWh AC-coupled Battery Energy Storage System (BESS) connected to the public grid via an existing 20 kV grid connection point at an adjacent MV/HV substation in 74821 Mosbach, Germany. At the grid connection point, the storage is supposed to deliver a power of 7.5 to a maximum of 10 MW and have a capacity of 2 to a maximum of 3 hours. The BESS should preferably be based on lithium-ion or sodium-ion battery technology and designed for commercial operation in the German electricity market. The possible lithium-ion technologies will be specified in more detail during the tender. The system is expected to support, among others, participation in Frequency Containment Reserve, Automatic Frequency Restoration Reserve, Day-Ahead and Intraday markets. The project site has already been secured and is currently used as agricultural land. The existing substation is located on the adjacent property, with an estimated cable route of less than 100 m. The site is located within Water Protection Zone III, which requires appropriate consideration of water protection, containment, drainage and environmental requirements. Planning permission for this project has not yet been granted. The project is intended to be tendered as a turnkey EPC project, including engineering, procurement, construction, installation, grid connection interface, testing, commissioning and handover of a fully operational BESS. The tender may also cover related maintenance services, which are subject to a Long-Term Service Agreement (LTSA). The contracting authorities reserve the right to set the term of this LTSA for up to 15 years. The companies have no legal right to conclude an LTSA with a specific term. The final technical requirements, interface definitions, contractual conditions and detailed scope of work will be specified during the subsequent RFP phase. Further information can be found in the procurement documents that will be issued after the conclusion of the participation competition.
