Load / gen is this hour’s demand divided by net generation (GRIDFRONT modeled). Not a reserve margin and not load / installed.

How regions are defined

Each EIA-930 respondent is in exactly one row. ISO/RTO BAs where they exist; EIA regions otherwise. No NERC SERC/FRCC roll-up.

PJM ← PJM
MISO ← MISO (includes MISO South / Entergy)
ERCOT ← ERCO
SPP ← SWPP
CAISO ← CISO
NYISO ← NYIS
ISO-NE ← ISNE
Southeast ← SE + TEN + CAR (not MISO, not FLA)
Florida ← FLA only
Northwest ← NW
Southwest ← SW

Map color uses primary-state membership as a convenience: Illinois ComEd is PJM; the rest of Illinois paints as MISO. Indiana is split. Texas panhandle is SPP. That coloring is not a BA boundary file.
