Metiscast Hub
metis/ercot-hubPrice forecasts for ERCOT's trading hubs.
Forecasts at the reference points bilateral and financial positions are written against — ERCOT's seven trading hubs, including the hub average.
How it works
The same Metiscast model as the nodal and zonal products, addressed at hub settlement points. Hubs are the reference prices most contracts are struck on, so this is the product to compare against a forward curve or a cleared day-ahead position. Issued every 15 minutes at five-minute resolution, across horizons from one hour to one week.
Inputs
- ERCOT settlement-point prices — real-time (SCED) and day-ahead
- System load, generation mix, and renewable output
- Weather fields — forecast and observed
- Grid geography — settlement-point coordinates and network topology
Outputs
- A p50 price path with its p10 and p90 band, per horizon
- Five-minute resolution across a 48-hour realized and forward window
- An issuance timestamp, so a forecast can be scored against what it knew
Three ways to consume it
product · inference · MCPIn the product
Metiscast Hub powers Ask the Grid directly — the live map, the radar, and the grid agent read it in place, so the same model you'd call is the one already reasoning over the grid on screen.
Developer inference service
A direct, typed inference API: request forecasts or embeddings by node and horizon and get structured results back. This is a plain inference endpoint — not MCP — for pipelines, notebooks, and services that want the model output without an agent in the loop.

The same model outputs, exposed as tools your own agent can call. Point a compatible client at the Ask the Grid MCP server and the model becomes a tool in your agent's own loop.
Build with MCPIntended use
- Comparing a model path against forwards and day-ahead clears
- Scoring a forecast vintage against what actually settled
- Feeding dispatch, hedging, and position models that need a distribution rather than a point
Limitations
- ERCOT only today; other markets follow as evaluation lands
- Probabilistic, not a guarantee — the band is the forecast, not decoration
- Bands widen with horizon; a one-week path is not a five-minute nowcast
