Battery energy storage systems (BESSs) have attracted significant attention in managing RESs [12], [13], as they provide flexibility to charge and discharge power as needed. A battery bank, working based on lead–acid (Pba), lithium-ion (Li-ion), or other technologies, is connected to the grid through a converter.
Although EES systems may not be the primary energy storage systems for the electric grid, they are necessary units due to their fast response time. In the future, the share of renewable energy such as solar photovoltaics (solar PV) and wind energy will increase in the electrical grid utilities, which will cause power and frequency fluctuations.
By definition, a Battery Energy Storage Systems (BESS) is a type of energy storage solution, a collection of large batteries within a container, that can store and discharge electrical energy upon request. The system serves as a buffer between the intermittent nature of renewable energy sources (that only provide energy when it''s sunny or ...

Base year costs for utility-scale battery energy storage systems (BESS) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2021). The bottom-up BESS model accounts for major components, including the LIB pack, inverter, and the balance of system (BOS) needed for the installation.
The average energy capacity cost of utility-scale battery storage in the United States has rapidly decreased from $2,152 per kilowatthour (kWh) in 2015 to $625/kWh in 2018. Battery storage systems store electricity produced by generators or pulled directly from the electric power grid and redistribute the power later as needed.
