Ercot Rate Limits

ERCOT publishes a single flat throttle for the Public Data API — 30 requests per minute, roughly one request every two seconds — applied regardless of subscription or product. There are no tiers and no documented way to raise it. Two further hard limits sit alongside it: historic file downloads are capped at 1,000 files per download, and traffic originating outside the United States is blocked at the edge for all *.ercot.com properties.

Ercot Rate Limits is the machine-readable rate-limit profile for ERCOT on the APIs.io network, in the API Commons Rate Limits shape.

It captures 2 rate-limit definitions, measuring requests_per_minute and files_per_download.

Limit state is signalled in the rateLimit, retryAfter, and note response headers, and an exhausted limit returns HTTP 429.

The profile also includes response codes documented for throttled.

Tagged areas include Rate Limiting, Energy Markets, and Open Data.
