Battery storage costs have fallen dramatically over the past two years, and the decline continues. Following a steep decline in 2024, Ember's analysis indicates that prices continued to fall sharply again in 2025.
According to BloombergNEF's annual survey, battery prices in 2025 remained at $108 per kilowatt-hour, an eight percent decrease. Experts also anticipate further price declines next year, although at a slower rate than in 2025 due to high raw material costs and tariffs.
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).
Experts also anticipate further price declines next year, although at a slower rate than in 2025 due to high raw material costs and tariffs. BloombergNEF expects the average price of a battery pack to decline to 105 US dollars per kilowatt-hour by 2026, a three per cent reduction.
The cost of four-hour lithium-ion (Li-ion) battery systems could decline from $334/kWh in 2024 to as low as $108/kWh or remain as high as $307/kWh by 2050, according to the National
