Lieferung, Montage und Inbetriebnahme eines Batteriespeichers (BESS II Harrislee)

TENDER DESCRIPTION

The subject of this project is the construction and operation of a grid-connected stand-alone battery storage system (BESS) with an electrical connection capacity of 70 MW and a usable storage capacity of 140 MWh on the customer's premises. The storage system is to be connected to the customer's own 60 kV medium voltage network via a medium voltage transformer and is intended for participation in arbitrage trading. The installation site of the battery storage is located on a greenfield site owned by STADTWERKE FLENSBURG GMBH (SWFL). The system is to be implemented as a containerized or modular storage solution, consisting of battery systems, inverter units, transformer technology, protection and control technology as well as the necessary auxiliary facilities. The storage capacity is to be used for participation in energy trading. In particular, the marketing of flexibilities through short-term electricity markets is planned in order to generate revenues from price spreads and market-driven arbitrage potentials. In addition, the battery storage system is to be used to provide secondary control reserve (aFRR) and thereby generate additional revenue from participation in the…
