Technical FAQs 4

How much does a battery storage system cost?

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.

Will energy storage growth continue through 2025?

With developers continuing to add new capacity, including 9.2 GW of new lithium-ion battery storage capacity in 2024 through November 2024 and comparable levels of growth expected through the fourth quarter of 2024, energy storage investments and M&A activity are expected to continue this trajectory through 2025.

Will US energy storage growth slow down in 2026?

That means costs in 2026 would return back to 2024 levels which could slow down the growth in US energy storage deployments, but the analyst says that even so, BNEF anticipates that the momentum of the country’s energy storage industry and growth in deployments would remain strong.

How have battery prices changed over the past decade?

The price of batteries is one of the biggest factors affecting the growth of electric vehicles (EVs) and energy storage. Over the past decade, battery prices have fallen drastically, making EVs more affordable and energy storage more viable. But how much have these prices actually dropped? And what does the future hold for battery costs? 1.
