6 FAQs about [Industry standard for energy storage cost per kilowatt-hour]
What is the cost of energy storage?
The cost of energy storage varies by technology. According to a 2018 report by RedT Energy Storage, the cost of their Gen 2 machines starts at $490/kWh.
How are battery energy storage costs forecasted?
Forecast procedures for battery energy storage costs are described in the main body of this report. C&C or engineering, procurement, and construction (EPC) costs can be estimated using the footprint or total volume and weight of the battery energy storage system (BESS). For this report, volume was used as a proxy for these metrics.
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.
What is the minimum power required for energy storage?
Objective: To compare cost and performance of various energy storage technologies. Minimum system power = 500 kW. DC system (two or more columns provided if you have two different systems on offer). Active heat exchanger (HEX)?
Why do we use units of $/kWh?
We use the units of $/kWh because that is the most common way that battery system costs have been expressed in published material to date. The $/kWh costs we report can be converted to $/kW costs simply by multiplying by the duration (e.g., a $300/kWh, 4-hour battery would have a power capacity cost of $1200/kW).
What is the cost of a 1,000 kW power system?
Maxwell provided a cost of $241,000 for a 1,000 kW/7.43 kWh system, while a 1,000 kW/12.39 kWh system cost $401,000 (Garcia 2018). On the $/kW power level, flow batteries are more competitive due to their high specific power and power density.
