Construction costs of energy storage projects in the United States

6 FAQs about [Construction costs of energy storage projects in the United States]

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 much does a non-battery energy storage system cost?

Non-battery systems, on the other hand, range considerably more depending on duration. Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours.

What are energy storage cost metrics?

Cost metrics are approached from the viewpoint of the final downstream entity in the energy storage project, ultimately representing the final project cost. This framework helps eliminate current inconsistencies associated with specific cost categories (e.g., energy storage racks vs. energy storage modules).

How much does gravity based energy storage cost?

Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours. Li-ion LFP offers the lowest installed cost ($/kWh) for battery systems across many of the power capacity and energy duration combinations.

How many battery energy storage projects are there?

The U.S. has 575 operational battery energy storage projects 8, using lead-acid, lithium-ion, nickel-based, sodium-based, and flow batteries 10. These projects totaled 15.9 GW of rated power in 2023 8, and have round-trip efficiencies between 60-95% 24.

How does energy storage impact the grid and transportation sectors?

Energy storage and its impact on the grid and transportation sectors have expanded globally in recent years as storage costs continue to fall and new opportunities are defined across a variety of industry sectors and applications.
