A quote from the article:
The energy think tank’s analysis, based on October 2025 auctions in Italy, Saudi Arabia, and India and interviews with active developers, shows the cost of a full utility-scale battery system connected to the grid at $125/kWh for long-duration projects of four hours or more outside China and the United States. Core battery equipment delivered from China now costs roughly $75/kWh, with installation and grid connection adding about $50/kWh.
More details on financial analysis are in the article.
