Free QuoteEnergy storage system costs for four-hour duration systems exceed $300/kWh for the first time since 2017. Rising raw material prices, particularly for lithium and nickel, contribute to increased energy storage costs. Fixed operation and maintenance costs for battery systems are estimated at 2.5% of capital costs.
As we look ahead to 2024, energy storage system (ESS) costs are expected to undergo significant changes. Currently, the average cost remains above $300/kWh for four-hour duration systems, primarily due to rising raw material prices since 2017.
Figure ES-2 shows the overall capital cost for a 4-hour battery system based on those projections, with storage costs of $245/kWh, $326/kWh, and $403/kWh in 2030 and $159/kWh, $226/kWh, and $348/kWh in 2050.
The 2020 Cost and Performance Assessment analyzed energy storage systems from 2 to 10 hours. The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations.
The long-term cost outlook for energy storage systems looks promising, with substantial reductions in capital expenditures expected over the next decade. For a 60MW 4-hour battery system, CAPEX reductions range from 18% to 52% between 2022 and 2035, depending on the scenario.
Around the beginning of this year, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage system prices had fallen 40% from 2023 numbers to US$165/kWh in 2024.
