Exactly what a request answers with, read from the API rather than written here.
| Column | Type | Description |
|---|---|---|
| interval_start_utcrequired | timestamp | Start of the interval, UTC, read from PJM's own UTC column.e.g. 2026-09-09T12:30:00Z |
| isorequired | string | Publishing ISO.e.g. PJM |
| gen_mwrequired | number | Wind output across the PJM RTO at the reading, MW.e.g. 2658 |
| source_published_at_utc | timestamp | When PJM published the row, UTC. |
| collected_at_utcrequired | timestamp | When Dryos collected this row, UTC. Stamped by the platform, not the collector.e.g. 2026-09-09T12:35:12Z |

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.
- 2026-09-09
First collected, from PJM Data Miner 2.
Non-member API access was granted on 2026-09-09. Reconciled against live responses the same day: schema, nulls, primary key, value bands and row counts all passed, and the energy identity and the node naming rule were checked row-for-row against the day-ahead feed and the pricing-node master.
How this stream is checked
- Pulled straight from PJM Data Miner 2 · instantaneous_wind_gen — 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 every 15 s; 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.
