Overview

This is the subset of utility-scale battery and energy storage resources reported in the EIA-860 generator inventory, covering plant and owner identifiers, location, capacity, and operating status alongside storage-specific attributes such as maximum charge and discharge rates, useful-life energy in MWh, and storage technology. It is updated annually with a full snapshot and refreshed monthly between cycles. The duration and power ratings let you separate short-duration frequency-regulation assets from longer-duration shifting resources, and tracking new entries over time shows where storage is being added across the grid. Operators, traders, and researchers use it as the authoritative reference for what storage exists, where it sits, and how much energy and power it can move.
