Technical FAQs 4

How much does energy storage cost?

Energy storage system costs for four-hour duration systems exceed $300/kWh for the first time since 2017. Rising raw material prices, particularly for lithium and nickel, contribute to increased energy storage costs. Fixed operation and maintenance costs for battery systems are estimated at 2.5% of capital costs.

How much does energy storage cost in 2024?

As we look ahead to 2024, energy storage system (ESS) costs are expected to undergo significant changes. Currently, the average cost remains above $300/kWh for four-hour duration systems, primarily due to rising raw material prices since 2017.

Why are energy storage systems so expensive?

Energy storage systems (ESS) for four-hour durations exceed $300/kWh, marking the first price hike since 2017, largely driven by escalating raw material costs and supply chain disruptions. Geopolitical issues have intensified these trends, especially concerning lithium and nickel.

What is NREL's solar-plus-storage cost benchmarking work?
