Per-unit readings come from nine primary sources — the NRC (United States), JAIF (Japan), IESO (Canada), Elexon BMRS (United Kingdom), CAMMESA (Argentina), KHNP (South Korea), Vattenfall (Sweden), ONS (Brazil) and the Central Electricity Authority (India) — matched against the installed capacity in Reactor Atlas's dataset. India starts from an exceptions report, so a unit missing from that report is taken as operating.
France is followed through RTE eCO2mix and EDF press releases; the rest of the ENTSO-E zone, through the unavailability notices its operators file with the Transparency Platform.
Cadence depends on the source: minutes for CAMMESA, KHNP and Vattenfall; hourly for Elexon, IESO and ENTSO-E; a daily report for the NRC, ONS and the Central Electricity Authority; JAIF publishes a new table monthly. This page recalculates every 15 minutes, and a unit missing from its source's latest report is shown as no data, never as operating.
