InfraSure returned a partial, non-exhaustive set of 25 ISONE operating plants with identity fields (name, state, primary fuel, capacity MW, owner, county, lat/lon); this is a bounded result page, not the full fleet.
Result set is explicitly marked partial/paginated; no dataset refresh timestamp was reported, so freshness is unknown. Coverage does not establish these are the top 25 or top 100 by any completeness metric.
