Factoring in these costs from the beginning ensures there are no unexpected expenses when the battery reaches the end of its useful life. To better understand BESS costs, it’s useful to look at the cost per kilowatt-hour (kWh) stored. As of recent data, the average cost of a BESS is approximately $400-$600 per kWh. Here’s a simple breakdown:
MWh (Megawatt-hour) is a measure of energy capacity (how long the system can continue delivering that power output). For example, a 1 MW / 4 MWh BESS has four hours of storage capacity.So, while the system might be $200,000 per MW, the effective cost can be $800,000 per MWh if it has four hours duration.
Several factors can influence the cost of a BESS, including: Larger systems cost more, but they often provide better value per kWh due to economies of scale. For instance, utility-scale projects benefit from bulk purchasing and reduced per-unit costs compared to residential installations. Costs can vary depending on where the system is installed.
The cost of BESS has fallen significantly over the past decade, with more precipitous drops in recent years: This is nearly a 70% reduction in three years, owing to falling battery pack prices (now as low as $60-70/kWh in China), increased deployment, and improved efficiency.
O&M costs are typically lower for lithium-ion systems due to fewer moving parts, but they should still be factored into your long-term budget. Modern BESS solutions often include sophisticated software that helps manage energy storage, optimize usage, and extend battery life.
It is nonetheless still eye-opening to note just how big those differences in cost are. The average for a turnkey system in China including 1-hour, 2-hour and 4-hour duration BESS was just US$101/kWh. In the US, the average was US$236/kWh and in Europe US$275/kWh, more than double China’s average cost.
