All-in BESS projects now cost just $125/kWh as of October 2025 2.

How much does energy storage cost?

**Battery Cost**: The battery is the core component of the energy storage system, and its cost accounts for a significant portion of the total cost. As of 2024, the cost of lithium-ion batteries, which are widely used in energy storage, has been declining. On average, the cost of lithium-ion battery cells can range from $0.3 to $0.5 per watt-hour.

How much does a lithium ion battery cost?

On average, the cost of lithium-ion battery cells can range from $0.3 to $0.5 per watt-hour. For a 2MW (2,000 kilowatts) battery storage system, if we assume an average battery cell cost of $0.4 per watt-hour, the cost of the battery alone would be 2,000,000 * $0.4 = $800,000.

How much does a 4 hour battery system cost?

Figure ES-2 shows the overall capital cost for a 4-hour battery system based on those projections, with storage costs of $147/kWh, $243/kWh, and $339/kWh in 2035 and $108/kWh, $178/kWh, and $307/kWh in 2050 (values in 2024$).
