How Much Does a BESS System Cost? Guide & Analysis
A BESS system enables efficient energy storage, making it easier to integrate renewable sources like solar and wind into the grid. This article explores the cost of a BESS
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:
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
The average 2024 price of a BESS 20-foot DC container in the US is expected to come down to US$148/kWh, down from US$180/kWh last year, a similar fall to that seen in 2023, as reported by Energy-Storage.news, when CEA launched a new quarterly BESS pricing monitor.
BoS includes all components other than the battery, such as inverters, transformers, cooling systems, wiring, and structural supports. Inverters are crucial as they convert the stored DC energy into AC energy usable by your home or the grid. These components can add up to 30-40% of the total BESS cost.
