Energy storage system installation price standard table

What are base year costs for utility-scale battery energy storage systems?

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., 2022). 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.

What are the different types of energy storage costs?

The cost categories used in the report extend across all energy storage technologies to allow ease of data comparison. Direct costs correspond to equipment capital and installation, while indirect costs include EPC fee and project development, which include permitting, preliminary engineering design, and the owner’s engineer and financing costs.

What are energy storage cost metrics?

Cost metrics are approached from the viewpoint of the final downstream entity in the energy storage project, ultimately representing the final project cost. This framework helps eliminate current inconsistencies associated with specific cost categories (e.g., energy storage racks vs. energy storage modules).

How much does a 600 kW energy storage system cost?

Figure 19 shows the resulting costs in nameplate and usable capacity ($/kWh ) for 600-kW Li- ion energy storage systems, which vary from $481/kWh-usable (4-hour duration) to $2,154/kWh-usable (0.5-hour duration). The battery cabinet cost accounts for 47% of total system cost in the 4-hour system but only 19% in the 0.5-hour system.

Are energy storage systems cost estimates accurate?

The cost estimates provided in the report are not intended to be exact numbers but reflect a representative cost based on ranges provided by various sources for the examined technologies. The analysis was done for energy storage systems (ESSs) across various power levels and energy-to-power ratios.

How much does a 5 kW storage system cost?

23 This report is available at no cost from the National Renewable Energy Laboratory (NREL) at As demonstrated in Figure 13, the kit for a 5-kW/12.5-kWh storage system costs approximately $6,406–$6,662 with a total installed cost of $15,852 (DC-coupled) to $16,715 (AC-coupled).
