suiren 1 daily electricity load forecasts

Every day, suiren 1 forecasts electricity demand for 32 European countries. This dataset holds the results. Each forecast gives the hourly load in megawatts (MW) from the first hour with no published load to the end of tomorrow, UTC.

The suiren 1 MCP server at https://suiren-anatomy.pages.dev/mcp serves these forecasts to AI agents.

Files

latest.json is the file to read. Fetch it from this URL:

https://huggingface.co/datasets/kitfunso/suiren-1-forecasts/resolve/main/latest.json

It holds one JSON object with these keys:

• model: the model name, suiren-1.
• run_issued_at: the start time of the last run, whether it worked or not.
• zones: the last good forecast for each zone. A zone that failed today keeps its older record, so check its issued_at.
• failed: the zones that failed in the last run only. Each entry holds the error and the time at.
• zone_info: the country name and a note for each zone.

latest.csv is the same forecasts as a flat table, one row per zone and hour, for the dataset viewer and spreadsheets. Its columns are zone, issued_at, hour_utc, p05_mw, p50_mw and p95_mw, and an empty cell is a null band.

runs/ holds one file per run, named by the UTC minute the run started, such as runs/2026-10-26T0945Z.json. A run file holds only the zones that passed and failed in that run. Nobody rewrites a run file.

One forecast record

This is the be record from a real run, cut to three rows.

{"model": "suiren-1", "zone": "be", "issued_at": "2026-10-25T16:54:21Z",
 "first_hour_utc": "2026-10-25T02:00Z", "unit": "MW", "seeds": [0],
 "missing_history_hours": 0,
 "rows": [
  {"hour_utc": "2026-10-25T02:00Z", "p05_mw": 6752, "p50_mw": 6953, "p95_mw": 7151},
  {"hour_utc": "2026-10-25T03:00Z", "p05_mw": 6752, "p50_mw": 6953, "p95_mw": 7217},
  {"hour_utc": "2026-10-25T04:00Z", "p05_mw": 6887, "p50_mw": 7151, "p95_mw": 7480}]}

• issued_at is the time this zone's run started.
• first_hour_utc is the first hour that has no published load yet.
• p05_mw, p50_mw and p95_mw are the 5th, 50th and 95th percentiles of the forecast. The span from p05_mw to p95_mw is the model's 90 percent range around the median p50_mw.
• A band is null when the model gave no number for it.
• missing_history_hours counts the gaps in the 2,048 hours of load history the model read.

Schedule

A run starts every day at 09:45 London time. That is 75 minutes before the 12:00 Brussels gate of the day-ahead auction. If issued_at for a zone is more than a day old, a run was missed or that zone keeps failing.

Zones

There are 32 zones: at, ba, be, bg, ch, cz, de, dk, ee, es, fi, fr, ge, gr, hr, hu, ie, it, lt, lu, lv, md, nl, no, pl, pt, ro, rs, se, si, sk and xk. The model trained on 33 zones. The 33rd, gb, is not live. Its target is Elexon demand, and Energy-Charts does not serve it. zone_info carries this note for gb.
