Ember provides the latest capex and Levelised Cost of Storage (LCOS) for large, long-duration utility-scale Battery Energy Storage Systems (BESS) across global markets outside China and the US, based on recent auction results and expert interviews. 1. All-in BESS projects now cost just $125/kWh as of October 2025 2.
Trends in energy storage costs have evolved significantly over the past decade. These changes are influenced by advancements in battery technology and shifts within the energy market driven by changing energy priorities.
As can be seen in the chart below, the ITC brings down the cost significantly, with 100MW, 4-hour utility-scale standalone energy storage ranging from US$83/MWh if deployed in areas designated as 'energy communities' (regions with economies historically dependent on coal and other conventional energy technologies) up to US$192/MWh at the top end.
Lower costs are meeting higher electricity prices in several regions of the US, driving energy storage adoption in states where municipal utility procurement of electricity and data centre growth are prevalent, Lazard said.
To evaluate the technical, economic, and operational feasibility of implementing energy storage systems while assessing their lifecycle costs. This analysis identifies optimal storage technologies, quantifies
