According to Ember, the cost of a whole, grid-connected utility-scale battery storage system for long-duration projects (four hours or more) is now about $125 per kilowatt-hour (kWh) as of October 2025. That figure applies to projects outside China and the US.
For smaller commercial and industrial (C&I) energy storage projects in the 50–500 kWh range, installed costs typically fall in the range of USD $500–$1,000 per kWh.
Because of all these variables, the $280–$580/kWh range is best used as a quick planning guide—useful for early budgeting, screening opportunities, or checking whether a quote is broadly in line with market expectations.
Recent pricing trends show 20ft containers (1-2MWh) starting at $350,000 and 40ft containers (3-6MWh) from $650,000, with volume discounts available for large orders.
Price is $387,400 each (for 500KWH Bank) plus freight shipping from China. To discuss specifications, pricing, and options, please call Carl at (801) 566-5679. Each container with all of the equipment will weigh less than 16 tons. Fully tested before being shipped.
