ERCOT Day-Ahead Settlement Point Prices

These are the prices at which energy is bought and sold a day in advance of delivery, set the afternoon before each operating day. They are the day-ahead counterpart to real-time locational prices, and the gap between the two reflects how the market expected conditions to differ from how they actually unfolded. Traders use them to position and hedge, generators and loads use them to plan commitments, and researchers use them to study how congestion and scarcity show up across the grid.

Query contract

Read ercot.spp_day_ahead_hourly with FINAL so repeated ingestion revisions collapse to one row per settlement point and delivery hour.

Analysis rules

For an ERCOT trading-hub comparison, use the canonical hubs HB_HOUSTON, HB_NORTH, HB_SOUTH, HB_WEST, and HB_PAN. Do not include HB_BUSAVG or HB_HUBAVG unless the user explicitly asks for aggregate hub indices.Aggregate only after revision collapse; otherwise repeated ingestions multiply every delivery hour.

Interpretation

ERCOT clears its day-ahead market around midday and posts the results by about 1:30 PM Central the day before delivery. Before early afternoon Central time, the next day's prices have not been published yet — that is the market's schedule, not missing coverage; offer today's cleared prices instead.
