From 2020 to 2021, residential PV-plus-storage levelized cost of energy (LCOE) fell 13%, and residential stand-alone PV LCOE fell 9%; there were 7% and 13% reductions in levelized electricity costs for commercial and utility-scale PV-plus-storage systems.
What is the bottom-up cost model for battery energy storage systems?
Current 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 (Feldman 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.
Did storage system costs decrease between 2020 and 2021?
The 2020 benchmarks used the more moderate locations of Phoenix, Arizona (High) and New York City, New York (Low), which explains the widened range of outcomes. When accounting for these changes and other model updates the storage system kit costs actually decreased between 2020 and 2021.
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).12 Also, Figure 14 (page 24) shows the cost of residential storage systems for different system capacities. Figure 13.
Additional storage technologies will be added as representative cost and performance metrics are verified. The interactive figure below presents results on the total installed ESS cost ranges by technology, year, power capacity (MW), and duration (hr).
