As of recent data, the average cost of commercial & industrial battery energy storage systems can range from $400 to $750 per kWh. Here's a breakdown based on technology:.
What are base year costs for utility-scale battery energy storage systems?
Base year costs for utility-scale battery energy storage systems (BESSs) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2023). The bottom-up BESS model accounts for major components, including the LIB pack, the inverter, and the balance of system (BOS) needed for the installation.
Are battery energy storage systems worth the cost?
Battery Energy Storage Systems (BESS) are becoming essential in the shift towards renewable energy, providing solutions for grid stability, energy management, and power quality. However, understanding the costs associated with BESS is critical for anyone considering this technology, whether for a home, business, or utility scale.
Does NREL have a long-term battery energy storage system?
The US National Renewable Energy Laboratory (NREL) has updated its long-term battery energy storage system (BESS) costs through to 2050.
Are battery storage costs based on long-term planning models?
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
Why is Bess so expensive compared to a lithium-ion battery?
A big driver of the fall in BESS costs will be a decline in the costs of the battery cells and packs themselves, which can make up half the cost of a lithium-ion BESS.
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, and $348/kWh in 2050.
