Changes to this collector
A change in the collector is a change in the data. Anyone reading a step in a series is owed the day it moved under them.
- 2026-09-13
First collected, from PJM Data Miner 2.
PJM's daily generation outage forecasts, kept by PJM indefinitely. Reconciled against live responses on 2026-09-13.
How this stream is checked
- Pulled straight from PJM Data Miner 2 · gen_outages_by_type — no reseller in between — and compared against that file before it is served.
- Null means the source did not report it — never zero.
- A reading lands daily, a week ahead; the interval timestamp is the start of the interval, in UTC.
- PJM's Eastern Prevailing Time observes daylight saving; its rows carry UTC as well. Every timestamp Dryos serves is UTC.
