- Yes — the map above. Each dot is one battery storage project, sized by nameplate capacity and placed at the coordinates EIA files for it.
- Which is the largest battery storage project in Indiana?
- Petersburg Energy Center, at 500 MW. The table is sorted largest first, so the rest follow it.
- Is there a battery storage project near me in Indiana?
- The county roll-up below groups every plant by county, which is the quickest way to find the one closest to a given town.
- Which grid operator runs Indiana's battery storage projects?
