Columns
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. Always UTC — ERCOT publishes wall-clock Central with a repeated-hour flag, which is resolved on ingest.e.g. 2026-08-29T14:15:00Z |
| isorequired | string | Publishing ISO.e.g. ERCOT |
| zonerequired | string | ERCOT forecast zone: SOUTH, NORTH, WEST or HOUSTON.e.g. SOUTH |
| total_resource_mwrequired | number | Total resource capacity on outage, MW.e.g. 1997 |
| total_irr_mwrequired | number | Intermittent renewable capacity on outage, MW.e.g. 998 |
| total_new_equip_mwrequired | number | New-equipment capacity not yet commercial, MW.e.g. 850 |
| source_published_at_utcrequired | timestamp | When ERCOT posted the document this row came from, UTC. For reports republished on a rolling window this is the vintage: the same interval appears once per publication, and the newest is the current view.e.g. 2026-08-29T14:17:01Z |
| collected_at_utcrequired | timestamp | When Dryos collected this row, UTC. Stamped by the platform, not the collector.e.g. 2026-08-29T14:18:02Z |

How this stream is checked
- Pulled straight from ERCOT MIS · NP3-233-CD — 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 hourly, week out; the interval timestamp is the start of the interval, in UTC.
- ERCOT settles and publishes on US Central time. Every timestamp Dryos serves is UTC.
