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

Base year costs for utility-scale battery energy storage systems (BESS) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2021). The bottom-up BESS model accounts for major components, including the LIB pack, inverter, and the balance of system (BOS) needed for the installation.

What is the 2022 cost and performance assessment?

The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations. In September 2021, DOE launched the Long-Duration Storage Shot which aims to reduce costs by 90% in storage systems that deliver over 10 hours of duration within one decade. The analysis of longer duration storage systems supports this effort.

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

How did bid cost recovery affect batteries in 2022?

Bid cost recovery payments for batteries increased significantly in 2022. In 2022 battery resources received 10 percent of all bid cost recovery, while accounting for about 5 percent of capacity in the CAISO market. These payments represent about 7.6 percent of net market revenue for batteries.

How much does SB cost in 2022?

The low estimate SB cost for 2022 report is 77% of the 2020 report cost for 2-hour duration and 55% at 100-hour duration. This translates to installed capital cost ratio of 77–87% of 2020 report cost. Table 4.8 shows the cost components for the year 2030 for 10 MW systems across the 2–100 hour duration. Table 4.8.

How much does a battery cost in 2022?

The average price spread in battery bids in the real-time market increased from $119 in 2021 to $167 in 2022. The increasing real-time nodal prices in 2022 coincide with an increase in both charging and discharging bids.
