Large battery storage units are very versatile and truly multi-talented.
The large battery storage systems can absorb power or release it as needed. This serves the balancing energy markets and stabilises the frequency.
In addition, the storage units can be black-started and islanded, and in an emergency they provide a secure power supply. Furthermore, the inverters can compensate for reactive power and smooth load peaks. In the case of dynamic energy prices, energy can additionally be taken up when prices are favourable in order to release it again at peak prices.
