Data dictionary

Every dataset and every field a subscriber receives, tagged by plan. Delivered through data.ornn.com and the REST API at https://api.ornnai.com, with CSV/XLSX export from charts and tables on Full only. This is version 4.0, effective August 19, 2026. It supersedes the v3 dictionary (Public vs Full Data only) by adding Premium ($500/month, daily grain) as a first-class column. Compare plans at data.ornn.com/pricing. Grain and key rules are in Access tiers. When those rules change, this page must change with them — backend/tests/data-dictionary-gating.test.js fails the PR otherwise. Ornn Data LLC, 447 Broadway FL 4, New York, NY 10013.

access on a keyed response is premium or full. On the Basic window it is public-3mo (GPU) or public-1mo (OTPI).

11. Power Markets

Daily wholesale power prices across every US market, with history from 2017-01-03. Six markets are ICE exchange trades carrying the volume behind each print; ERCOT is its own day-ahead clearing price, shown against grid load. No Basic window.
