The Hamburger Energiewerke GmbH (HEnW) is a 100% municipally owned energy utility of the Free and Hanseatic City of Hamburg. In the course of the energy transition and the coal phase-out, HEnW is further developing the site of the former Moorburg hard-coal power plant into a modern energy site. The entity responsible for this site development is HEnW Energiehub Moorburg GmbH (hereinafter the "Client"), a company of Hamburger Energiewerke, which is implementing and operating the "Energie Hub Moorburg (EHM)". One sub-project of this site development is the construction of a large-scale Battery Energy Storage System (BESS). To realise this plant, the Client intends to commission a general contractor under an EPC contract model (Engineering, Procurement and Construction). This project description forms the basis of the preceding prequalification competition and informs interested applicants about the subject, scope and key boundary conditions of the project.

LOT-0001
Construction of the Battery Storage Moorburg.
The objective of the project is the construction of an operational battery storage facility with an installed power of 200 MW and a storage capacity between 400 and 800 MWh. The plant is designed as a commercially operated facility and is primarily geared towards participation in the wholesale electricity market (day-ahead and intraday) and the balancing energy markets. It is intended to contribute to the stabilisation of the power grid, support the integration of renewable energies and provide flexibility within the energy system. The project is realised entirely under an EPC contract. The contractor assumes overall responsibility for the design, procurement, construction, commissioning and handover of the turnkey plant. The supply and performance boundary is formed by the substation to which the storage facility is connected. In addition, the tender covers the transition into operation as well as long-term operational safeguards. These include in particular a multi-year operation and maintenance contract (O&M), availability and performance guarantees including safeguarding of the capacity over the service life (degradation), extended warranty and long-term guarantees as well as a secured spare parts stock. The objective is reliable and economic plant operation throughout the entire life cycle.
