2026-05-18 | ERCOT asset database schema updates

2 days ago

Changed

ERCOT asset database

The endpoint now returns every ERCOT asset Modo tracks, including newly commissioned assets that were previously omitted while their market identifiers were still being populated. Fields tied to incomplete data come through as null instead of causing the asset row to be dropped.

Affected endpoint:

  • GET /pub/v1/us/ercot/modo/asset-database/

Nullable fields:

  • asset
  • load_zone

Required fields: All other response fields are now explicitly marked as required. They were always present in responses; the schema is now precise about it. For assets with incomplete data the value may be null.

Validation changes: String fields use minLength: 1 instead of maxLength: 255. Integer fields no longer expose explicit min/max bounds. load_zone keeps its ["south", "west", "north", "houston"] enum.
