The BESS comprises 27 containers, each of 2.5MWh capacity. The containers were designed and assembled by TotalEnergies’ battery subsidiary Saft. According to TotalEnergies, the project is built to ensure enough supply of electricity in the national grid, particularly during peak winter periods.
[pdf] Containerized Battery Energy Storage Systems (BESS) are essentially large batteries housed within storage containers. These systems are designed to store energy from renewable sources or the grid and release it when required. This setup offers a modular and scalable solution to energy storage.
[pdf] In order to accurately calculate power storage costs per kWh, the entire storage system, i.e. the battery and battery inverter, is taken into account. The key parameters here are the discharge depth [DOD], system efficiency [%] and energy content [rated capacity in kWh].
