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:
Complex installations in challenging locations or those requiring significant upgrades to existing systems will naturally incur higher costs. The cost of a BESS is often measured in dollars per kilowatt-hour (kWh). As of 2024, the average cost in California is approximately $1075/kWh. Here's a breakdown of costs for various system sizes:
Cooling: BESS often require cooling and/or heating systems to maintain optimal operating temperatures. The space required for a 1 GWh BESS depends on the specific battery technology used. However, for a rough estimate, we can use the energy density of modern lithium-ion batteries, which is around 200-300 Wh/L 2.
