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.
They are priced according to five different power ratings to provide a relevant system comparison and a more precise estimate. The power rating of an energy storage system impacts system pricing, where larger systems are typically lower in cost (on a $/kWh basis) than smaller ones due to volume purchasing, etc.
The survey methodology breaks down the cost of an energy storage system into the following categories: storage module, balance of system, power conversion system, energy management system, and the engineering, procurement, and construction costs.
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.
Costs are presented in $/kW per the convention used for expressing generator costs and also in $/kWh due to energy storage being an energy limited device. Caution should be used in evaluating installed costs simply through $/kW or $/kWh values, as scale and energy duration characteristics impact a specific project’s overall economics.
The following are the definitions of the different segments of an energy storage system starting with the central energy storage component and working outwards. Storage Module (SM): An assembly of energy storage medium components (battery) built into a modular unit to construct the energy storage capacity (kWh) of an energy storage system.
