4 FAQs about Battery energy storage 25

What is included in the battery storage update?

This battery storage update includes summary data and visualizations on the capacity of large-scale battery storage systems by region and ownership type, battery storage co-located systems, applications served by battery storage, battery storage installation costs, and small-scale battery storage trends.

What are energy storage batteries?

Energy storage batteries are manufactured devices that accept, store, and discharge electrical energy using chemical reactions within the device and that can be recharged multiple times throughout their usable life. They are used in conjunction with a wide range of energy, transportation, consumer, and manufacturing goods and services.

How big is battery storage capacity in the power sector?

Battery storage capacity in the power sector is expanding rapidly. Over 40 gigawatt (GW) was added in 2023, double the previous year's increase, split between utility-scale projects (65%) and behind-the-meter systems (35%).

Does battery storage cost reduce over time?

The projections are developed from an analysis of recent publications that include utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time.
