Recent Wood Mackenzie data shows 40% of commercial ESS quotes omit critical lifecycle costs. Here''s how to compare apples to alien fruit:
As of most recent estimates, the cost of a BESS by MW is between $200,000 and $450,000, varying by location, system size, and market conditions. This translates to around

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.
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.
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.
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.
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
Additional storage technologies will be added as representative cost and performance metrics are verified. The interactive figure below presents results on the total installed ESS cost ranges by technology, year, power capacity (MW), and duration (hr).
