Battery Energy Storage Systems (BESS) are becoming essential in the shift towards renewable energy, providing solutions for grid stability, energy management, and power quality. However, understanding the costs associated with BESS is critical for anyone considering this technology, whether for a home, business, or utility scale.
A standard 100 kWh system can cost between $25,000 and $50,000, depending on the components and complexity. What are the costs of commercial battery storage? Battery pack - typically LFP (Lithium Uranium Phosphate), GSL Energy utilizes new A-grade cells.
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.
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.
By expressing battery system costs in $/kWh, we are deviating from other power generation technologies such as combustion turbines or solar photovoltaic plants where capital costs are usually expressed as $/kW. 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.
Battery storage prices have gone down a lot since 2010. In 2025, they are about $200–$400 per kWh. This is because of new lithium battery chemistries. Different places have different energy storage costs. China’s average is $101 per kWh. The US average is $236 per kWh. Knowing the price of energy storage systems helps people plan for steady power.
