The belief that battery storage systems are prohibitively expensive, making them impractical for widespread use in residential and commercial settings, is outdated. While these systems were once costly, the price of batteries has significantly decreased over the past decade, making energy storage more accessible and cost-effective.From 2010 to 2022, the cost of lithium-ion batteries dropped by 89%, decreasing from around $1,100 per kilowatt-hour (kWh) to approximately $137/kWh.(1) This significant reduction has been driven by technological advancements, increased efficiency in production, economies of scale, and greater demand for renewable energy solutions.These storage systems play a crucial role in integrating renewable energy sources like wind and solar into the grid by enhancing grid reliability, and allowing homeowners and businesses to reduce their reliance on fossil fuels while achieving long-term energy savings.(2)
