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.

What are base year costs for utility-scale battery energy storage systems?

Base year costs for utility-scale battery energy storage systems (BESSs) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2023). The bottom-up BESS model accounts for major components, including the LIB pack, the inverter, and the balance of system (BOS) needed for the installation.

Are lithium ion batteries expensive?

Lithium-ion batteries are the most popular due to their high energy density, efficiency, and long life cycle. However, they are also more expensive than other types. Prices have been falling, with lithium-ion costs dropping by about 85% in the last decade, but they still represent the largest single expense in a BESS.

Do battery storage technologies use financial assumptions?

The battery storage technologies do not calculate levelized cost of energy (LCOE) or levelized cost of storage (LCOS) and so do not use financial assumptions. Therefore, all parameters are the same for the research and development (R&D) and Markets & Policies Financials cases.

Why is a Bess battery so expensive?

The battery is the heart of any BESS. The type of battery—whether lithium-ion, lead-acid, or flow batteries—significantly impacts the overall cost. Lithium-ion batteries are the most popular due to their high energy density, efficiency, and long life cycle. However, they are also more expensive than other types.

Are lithium-ion batteries more expensive than solid-state batteries?

As mentioned, lithium-ion batteries are popular but more expensive. Newer technologies like solid-state batteries promise higher performance at potentially lower costs in the future, but they are still in the developmental stage. Government incentives, rebates, and tax credits can significantly reduce BESS costs.
