BloombergNEF''s annual battery price survey finds a 14% drop from 2022 to 2023. New York, November 27, 2023 – Following unprecedented price increases in 2022, battery prices are falling again this year. The price of
Technology costs for battery storage continue to drop quickly, largely owing to the rapid scale-up of battery manufacturing for electric vehicles, stimulating deployment in the power sector. The rapid scaling up of energy storage
Released January 2022, the sixth report in the series focuses on how the grid could operate with high levels of energy storage. NREL used its publicly available Regional Energy Deployment System (ReEDS) model to identify least-cost
Future Years: In the 2023 ATB, the FOM costs and the VOM costs remain constant at the values listed above for all scenarios.. Capacity Factor. The cost and performance of the battery systems are based on an assumption of
Current Year (2021): The 2021 cost breakdown for the 2022 ATB is based on (Ramasamy et al., 2021) and is in 2020$. Within the ATB Data spreadsheet, costs are separated into energy and
21 Ciez and Whitacre (2016, a) The cost of lithium is unlikely to upend the price of Li-ion storage systems 22 Cole et al. (2016) Utility-scale lithium-ion storage cost projections for use in
In this work we describe the development of cost and performance projections for utility-scale lithium-ion battery systems, with a focus on 4-hour duration systems. The projections are
The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations. In September 2021, DOE launched the Long-Duration Storage Shot which aims to reduce costs by 90% in storage
In 2022, the estimated average battery price stood at about USD 150 per kWh, with the cost of pack manufacturing accounting for about 20% of total battery cost, compared to more than
This report is the basis of the costs presented here (and for distributed commercial storage and utility-scale storage); it incorporates base year battery costs and breakdown from (Ramasamy

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.
The projections are developed from an analysis of recent publications that include utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time. We use the recent publications to create low, mid, and high cost projections.
The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time. We use the recent publications to create low, mid, and high cost projections. Projected storage costs are $245/kWh, $326/kWh, and $403/kWh in 2030 and $159/kWh, $226/kWh, and $348/kWh in 2050.
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.
This battery storage update includes summary data and visualizations on the capacity of large-scale battery storage systems by region and ownership type, battery storage co-located systems, applications served by battery storage, battery storage installation costs, and small-scale battery storage trends.
In 2019, battery cost projections were updated based on publications that focused on utility-scale battery systems (Cole and Frazier 2019), with a 2020 update published a year later (Cole and Frazier 2020). This report updates those cost projections with data published in 2020 and early 2021.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
