Do battery storage technologies use financial assumptions?

The battery storage technologies do not calculate levelized cost of energy (LCOE) or levelized cost of storage (LCOS) and so do not use financial assumptions. Therefore, all parameters are the same for the research and development (R&D) and Markets & Policies Financials cases.

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.

How will technology innovation impact a 60-MW 4-hour battery?

For a 60-MW 4-hour battery, the technology innovation scenarios for utility-scale BESSs described above result in capital expenditures (CAPEX) reductions of 18% (Conservative Scenario), 37% (Moderate Scenario), and 52% (Advanced Scenario) between 2022 and 2035.

Will storage futures lead to cost reductions in 2021?

The Storage Futures Study report (Augustine and Blair, 2021) indicates NREL, BloombergNEF (BNEF), and others anticipate the growth of the overall battery industry—across the consumer electronics sector, the transportation sector, and the electric utility sector—will lead to cost reductions in the long term.

How do battery costs change over time?

This tends to make costs for longer-duration batteries (e.g., 10 hours) decrease more quickly and shorter-duration batteries (e.g., 2 hours) decrease less quickly into the future. All durations trend toward a common trajectory as battery pack costs decrease into the future.
