The Power Markets pages on data.ornn.com/analytics/power plot daily wholesale prices across the seven tracked US hubs: six ICE exchange-traded peak products, plus ERCOT’s day-ahead clearing price against grid load. History starts 2017-01-03. Premium and Full see the price charts; the hourly Load vs Forecast and Fuel Mix views require Full.
Power Markets has a REST API but no MCP tool. Premium and Full keys can read daily prices at GET /api/power/markets. Full keys can also read hourly grid operations at GET /api/power/load and GET /api/power/fuel-mix; a Premium key receives 403 on those two routes. CSV/XLSX export from the charts is Full-only.
The GPU forward curve is a separate product. Published GPU forward marks are served at GET /api/forward for paying keys and as the MCP tool get_forward_curve. They are not a power product. Do not look for power forwards on that route.

What the charts show

Tracked hubs: WECC Northwest (Mid C Peak), PJM, CAISO, ISO-NE, WECC Southwest (Palo Verde Peak), MISO, ERCOT (HB_NORTH). See the data dictionary §11 for the field list and access columns. The series is maintained by scheduled ingestion into the live data store. ICE-published hub workbooks can lag the trade date by weeks, while EIA operations feeds are hourly. Each response includes source and freshness metadata; the page stamps the latest source observation, not “today”. MISO trades thinly on ICE. Interpret its price together with traded volume.
