4 FAQs about Price of 2-hour and 4-hour energy storage

Why are 4 hour storage costs lower in 2024?

The 4-hour cost projections in this report are much lower in 2024 primarily due to the updated initial cost from the bottom-up cost model used in this work. The lower costs persist through 2050 because of that lower starting point. Table 2. Values from Figure 3 and Figure 4, which show the normalized and absolute storage costs over time.

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 $307/kWh in 2050 (values in 2024$).

What are storage costs?

Storage costs are overnight capital costs for a complete 4-hour battery system. Figure 9. Comparison of cost projections developed in this report (solid lines) against the values from the 2023 cost projection report (Cole and Karmakar 2023) (dashed lines). Figure 10.

Are battery storage costs based on long-term planning models?

Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
