Brazil battery storage cost reduction trajectory to decelerate through 2030

Consultancy Greener projects a deceleration in the cost decline of battery storage systems in Brazil, forecasting a 23% reduction from 2025 to 2030 compared to a 53% drop in the preceding five-year period. The analysis, based on 684 MWh of sales, suggests diminishing returns in cost efficiency for systems between 500 and 1,000 kWh capacity. This shift indicates a potential plateauing of the rapid price deflation that characterized the early 2020s.
