The rate at which the cost of energy storage batteries is falling

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.

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 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.

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.

Are battery prices affecting the transportation sector?

The transportation sector prioritizes dense and lightweight battery units, but there is more potential for cost reductions in larger, heavier energy storage batteries. The rapidly falling battery prices are already enabling the deployment of more renewable microgrids and solar home systems in areas lacking reliable grid access.

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.
