An energy storage system (ESS) is pretty much what its name implies—a system that stores energy for later use. ESSs are available in a variety of forms and sizes. For example, many utility companies use pumped-storage hydropower (PSH) to store energy. With these systems, excess available energy is used to pump water into a reservoir during
The battery energy storage system (BESS) can provide fast and active power compensation and improves the reliability of supply during the peak variation of the load in different interconnected areas. The energy storage facilities possess additional dynamic benefits such as load levelling, factor correction, and black start capability [4] .

Since China took the first step of 5G commercialization in 2019, by 2022, the number of 5G base stations built in China will reach 2.31 million. The power consumption of 5G base stations will increase by 3–4 times compared with 4G base stations [1, 2], significantly increasing the energy storage capacity configured in 5G base stations.
One particular Korean energy storage battery incident in which a prompt thermal runaway occurred was investigated and described by Kim et al., (2019). The battery portion of the 1.0 MWh Energy Storage System (ESS) consisted of 15 racks, each containing nine modules, which in turn contained 22 lithium ion 94 Ah, 3.7 V cells.
Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location. Storage system size range: 5–50 MW Target discharge duration range: 15 minutes to 1 hour Minimum cycles/year: 10–20.
