Battery storage becomes cheaper than gas turbines globally

A global economic shift is occurring as four-hour battery energy storage systems (BESS) become more cost-effective than open-cycle gas turbines. According to a Wood Mackenzie report, this trend holds true across 43 analyzed markets worldwide. The rising costs of gas turbines, driven by supply chain bottlenecks and increased demand from AI-powered data centers, contrast with the declining manufacturing costs of batteries.

Data centers are evolving from passive consumers into active energy nodes. By integrating BESS, these facilities can optimize consumption, manage power peaks, and provide grid stability services. This synergy is particularly vital as AI increases electricity demand and creates more variable consumption profiles.

In Germany, simulations by the Fraunhofer Institute for Solar Energy Systems ISE demonstrate the potential impact of large-scale storage. The study suggests that a 20 GW battery capacity could have significantly reduced electricity price spikes, dropping peak prices from 583 to 221 Euro per megawatt-hour during high-demand periods. Overall, large-scale batteries help smooth price volatility and stabilize the electrical system by charging during low-cost periods and discharging during peaks.
