Energy storage system product benchmarking

What are the benchmarks for PV and energy storage systems?

The benchmarks in this report are bottom-up cost estimates of all major inputs to PV and energy storage system (ESS) installations. Bottom-up costs are based on national averages and do not necessarily represent typical costs in all local markets.

How long does an energy storage system last?

The 2020 Cost and Performance Assessment analyzed energy storage systems from 2 to 10 hours. The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations.

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.

Are there cost comparison sources for energy storage technologies?

There exist a number of cost comparison sources for energy storage technologies For example, work performed for Pacific Northwest National Laboratory provides cost and performance characteristics for several different battery energy storage (BES) technologies (Mongird et al. 2019).

Should minimum sustainable price benchmarks be used for long-term PV cost analysis?

Minimum sustainable price (MSP) benchmarks provide an effective basis for long-term PV cost analysis. However, they do not represent dynamic market conditions and should not be used for near-term policy or market analysis.

What are asymmetric energy storage systems?

Asymmetric ECs are better suited for grid energy storage applications that have a long duration, for instance, charge-at-night/use-during-the-day storage. Because of their high power, long cycle life, and good reliability, the market and applications for ECs have been steadily increasing.
