Cost Projections for Utility-Scale Battery Storage: 2023 Update
Figure ES-2 shows the overall capital cost for a 4-hour battery system based on those projections, with storage costs of $245/kWh, $326/kWh, and $403/kWh in 2030 and $159/kWh, $226/kWh,

Base year installed capital costs for BESSs decrease with duration (for direct storage, measured in $/kWh) whereas system costs (in $/kW) increase. This inverse behavior is observed for all
Unlike a battery pack, which only stores energy, a BESS storage system is designed to manage power flow, timing, reliability, and operational strategy across different use cases.
