On-Grid Power

A battery storage system that plays a crucial role in support services for Transmission System Operators (TSOs) and imbalance services on the energy market. For a high level of reliability and safety, the system was built from two identical branches, each certified for 2.5 MW of grid-balancing power, with room for future expansion. It is used both for grid stability with ČEPS and for trading on the intraday electricity market.
