Using the detailed NREL cost models for LIB, we develop current costs for a 60-MW BESS with storage durations of 2, 4, 6, 8, and 10 hours, shown in terms of energy capacity ($/kWh) and power capacity ($/kW) in Figure 1 and Figure 2 respectively.
In 2022, volume-weighted price of lithium-ion battery packs across all sectors averaged $151 per kilowatt-hour (kWh), a 7% rise from 2021 and the first time BNEF recorded an increase in price. Now, BNEF expects the volume-weighted average battery pack price to rise to $152/kWh in 2023.
This report updates those cost projections with data published in 2021, 2022, and early 2023. The projections in this work focus on utility-scale lithium-ion battery systems for use in capacity expansion models. These projections form the inputs for battery storage in the Annual Technology Baseline (NREL 2022).
Lithium-ion battery pack price dropped to 139 U.S. dollars per kilowatt-hour in 2023, down from over 160 dollars per kilowatt-hour a year earlier. Lithium-ion batteries are one of the
Using the detailed NREL cost models for LIB, we develop base year costs for a 60-MW BESS with storage durations of 2, 4, 6, 8, and 10 hours, shown in terms of energy capacity ($/kWh) and power capacity ($/kW) in Figures 1 and 2, respectively.
In order to differentiate the cost reduction of the energy and power components, we relied on BNEF battery pack projections for utility-scale plants (BNEF 2019, 2020a), which reports battery pack costs as dollars per usable kWh of battery storage.
The $/kWh costs we report can be converted to $/kW costs simply by multiplying by the duration (e.g., a $300/kWh, 4-hour battery would have a power capacity cost of $1200/kW). To develop cost projections, storage costs were normalized to their 2018 value such that each projection started with a value of 1 in 2018.
The 2021 ATB represents cost and performance for battery storage with two representative systems: a 3 kW / 6 kWh (2 hour) system and a 5 kW / 20 kWh (4 hour) system. It represents lithium-ion batteries only at this time.
The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air
Average battery energy storage capital costs in 2019 were $589 per kilowatthour (kWh), and battery storage costs fell by 72% between 2015 and 2019, a 27% per year rate of decline. These lower costs support more capacity to store energy at each storage facility, which can
