Overview
ERCOT day-ahead locational marginal prices, one row per interval and location. 66.7M rows, 2017-01 to the next delivery day. Carries price_usd_mwh plus energy_usd_mwh and congestion_usd_mwh, with energy taken from ERCOT's DAM system lambda. No loss component: ERCOT does not publish one. Locations are node, zone, hub, interface; location_id joins atg.ercot_locations for the readable name, and kind is carried inline so a hub-only or zone-only question needs no join at all. Every market's day-ahead price table in this catalog has these same column names, so a cross-market price comparison is a UNION rather than a per-ISO rewrite. Revisions are already collapsed — read it plainly.
Use with MCP
This table is readable two ways, over the same guarded boundary. Over HTTP: POST /api/v1/datasets/ercot_prices_da/query, described in the API reference. Or from an MCP client: connect a market below, then use search_data or describe_data to load its query contract before calling query_data.
