BNEF finds 40% year-on-year drop in BESS costs
Around the beginning of this year, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage
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
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.
As of 2024, the average price for a utility-scale BESS is approximately $148/kWh 1. For a 1 GWh system, this translates to $148 million. It's important to note that this cost includes not just the batteries themselves, but also the inverters, control systems, and other balance of system components.
Looking ahead, it's expected the global BESS market will reach $120-$150 billion by 2030. The increasing level of investment in BESS has prompted competition between all major integrators seeking to capitalize on the opportunity to expand market share and capitalize on demand.
