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
fuelrequired	string	WIND or SOLAR.e.g. WIND
regionrequired	string	SYSTEM, or the report's region: load zones (LZ_WEST, ...) for the zonal wind report, geographic regions (PANHANDLE, CENTER_WEST, ...) for the geographic ones.e.g. SYSTEM
gen_mw	number	Hourly averaged actual generation, MW.e.g. 3710.55
cop_hsl_mw	number	COP high sustained limit for online resources, MW — what operators told ERCOT they could produce.e.g. 2360.3
forecast_stf_mw	number	ERCOT's short-term forecast (STWPF for wind, STPPF for solar), MW.e.g. 3812.6
forecast_pp_mw	number	ERCOT's production potential forecast (WGRPP for wind, PVGRPP for solar), MW.e.g. 3106.1
hsl_mw	number	Actual system-wide HSL, MW.e.g. 10994.2
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

Full parameters — bucketing, aggregation, filters and search — are on the API reference.

Ask an agent

The same stream through the Model Context Protocol, so Claude, ChatGPT, Cursor or any MCP client can query it directly.

shell

claude mcp add --transport http dryos https://api.dryos.ai/mcp

Then ask:

What has Actual generation been at PANHANDLE over the last 24 hours, and when did it peak?

Setup for every client is on the MCP server page.

How this stream is checked

Pulled straight from ERCOT MIS · NP4-742-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, rolling week; 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.
