Battery storage costs fall

Are battery storage costs falling?

Fortunately, this hurdle may soon be overcome due to the plummeting costs of battery storage, as outlined in a new report from the International Energy Agency (IEA). The IEA's "Batteries and Secure Energy Transitions" report finds that capital costs for battery storage systems are projected to fall by up to 40 percent by 2030.

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.

Why are battery prices falling in 2024?

Battery costs have fallen down substantially by over 90 percent in recent years to make energy storage an attractive investment for the solar and wind project developers. Notably, the global average lithium-ion battery pack prices have fallen 20 percent to USD 115 per kWh in 2024 which is the biggest annual fall as per BloombergNEF.

Are lithium-ion battery prices falling?

Yes, the price of lithium-ion battery cells has declined by 97% in the last three decades. A battery with a capacity of one kilowatt-hour cost $7500 in 1991 and just $181 in 2018.

By what percentage did battery prices fall between 2014 and 2018?

The cost of lithium-ion battery cells halved between 2014 and 2018. That’s a 50% reduction in just four years. The price of lithium-ion battery cells declined by 97% in the last three decades.

How will battery prices affect the future of electricity?

The rapidly falling battery prices are already enabling the deployment of more renewable microgrids and solar home systems in areas lacking reliable grid access. By 2030, the IEA projects that electricity costs for these systems paired with batteries could drop by nearly 50 percent.
