Dataset	Description
Daily generation capacityPJM · day publication	PJM's Daily generation capacity. Each row preserves a publisher record, workbook row, or report document with its source member and row index. Source timestamps, units, geographic scope, and revision qualifiers are retained in record_json; event_time is collection time; completed_at is when the entire document became available.
Live Dispatched Reserve Quantities, Requirements and ShortagesPJM · 5-minute	PJM five-minute real-time dispatched reserves by reserve area and product, with reported shortage indicators, reserve quantity, reserve requirement, reliability and extended requirements, market clearing price and MW adjustment. This is the live operational reserve-shortage evidence for synchronized, primary and 30-minute reserves, including PJM_RTO and Mid-Atlantic/Dominion, rather than the delayed settled reserve market results or regulation prices. Compare the same interval with energy prices to investigate reserve scarcity. Dispatch and pricing runs differ; this feed does not identify a specific generator trip or reconstruct energy LMP. Source timestamp strings are preserved alongside parsed UTC event_time.
Operational reserve quantitiesPJM · day publication	PJM's Operational reserve quantities. Each row preserves a publisher record, workbook row, or report document with its source member and row index. Source timestamps, units, geographic scope, and revision qualifiers are retained in record_json; event_time is collection time; completed_at is when the entire document became available.
Performance assessment intervalsPJM · day publication	PJM's Performance assessment intervals. Each row preserves a publisher record, workbook row, or report document with its source member and row index. Source timestamps, units, geographic scope, and revision qualifiers are retained in record_json; event_time is collection time; completed_at is when the entire document became available.
