What is the Cost of BESS per MW? Trends and
The cost per MW of a BESS is set by a number of factors, including battery chemistry, installation complexity, balance of system
As of most recent estimates, the cost of a BESS by MW is between $200,000 and $450,000, varying by location, system size, and market conditions. This translates to around $200 - $450 per kWh, though in some markets, prices have dropped as low as $150 per kWh. Key Factors Influencing BESS Prices
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:
• The table above shows a comparison of 2-hour BESS and 4-hour BESS costs for two example locations. EPC electrical scope ends at the high side of the MPT. Includes engineering, procurement, construction (EPC) contracting methodology. Estimated Costs exclude decommissioning costs and salvage values.
