The latest findings from Taipei-based intelligence provider TrendForce show that all-solid-state battery production volumes could have GWh levels by 2027. The rapid expansion will lead to cell price declines, reaching CNY 0. 7/Wh ($0,084-$0,098) level by 2035.
How are battery storage cost projections developed?
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.
Values range from 0.948 to 1.11. 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.

Do projected cost reductions for battery storage vary over time?
The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time. Figure ES-1 shows the suite of projected cost reductions (on a normalized basis) collected from the literature (shown in gray) as well as the low, mid, and high cost projections developed in this work (shown in black).
However, not all components of the battery system cost scale directly with the energy capacity (i.e., kWh) of the system (Fu, Remo, and Margolis 2018). For example, the inverter costs scale according to the power capacity (i.e., kW) of the system, and some cost components such as the developer costs can scale with both power and energy.
In 2019, battery cost projections were updated based on publications that focused on utility-scale battery systems (Cole and Frazier 2019), with updates published in 2020 (Cole and Frazier 2020) and 2021 (Cole, Frazier, and Augustine 2021). There was no update published in 2022.
