Are energy storage system costs falling

Why are battery energy storage systems (Bess) costs falling?

A growing industry trend towards larger battery cell sizes and higher energy density containers is contributing significantly to falling battery energy storage system (BESS) costs.

Are energy storage systems reducing the cost of batteries?

The scale of the reduction suggests that in addition to the falling cost of batteries—BNEF’s recent Lithium-ion Battery Price Survey found that battery pack prices fell 20% year-on-year to 2024, again the biggest drop recorded to date—energy storage system providers are working on cost reduction in other areas, Kikuma said.

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.

How much does energy storage cost in 2023?

Energy storage costs are not forgotten in the report either. Citing BloombergNEF data, cost per kWh have fallen to $165/kWh in 2023, down 40% from 2023, and half of the $375/kWh with data on the ongoing falls in costs attributed to a less constrained supply chain, dramatically lower lithium prices, and increased competition and scale.

Are battery electricity storage systems a good investment?

This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.

How much does a turnkey energy storage system cost?

According to BloombergNEF’s recently published Energy Storage System Cost Survey 2024, the prices of turnkey energy storage systems fell 40% year-on-year from 2023 to a global average of US$165/kWh. The research firm said this was the highest annual drop since its survey launched in 2017.
