EIA Report: Large-Scale Battery Storage in US Hits 10-Year High

Battery storage usage is on the upswing in the United States, as reported by the EIA. The utilization is especially high for large scale systems. Utility companies are increasingly turning to these systems, and their number more than doubled in the period from 2010 to 2018. More than 90% of the capacity is secured by the lithium-ion batteries. The installed costs are dramatically going down further increasing the appeal of the storage systems in power grids, both due to the technological advances and longer battery life.

Key Takeaways:

  • The number of operational battery storage systems in the US more than doubled from 2010 to 2018.
  • Despite their small populations, Alaska and Hawaii account for 14% of large-scale battery energy capacity.
  • From 2015 to 2017, average costs per-unit of energy capacity declined by 61%.

“The US Energy Information Administration (EIA) released a new report that examines national large-scale battery storage trends over the past decade.”
