The day-ahead price crosses below zero in this record. Zoom into a few days to see those intervals alongside the daily price cycle; a negative value is an observed price, not missing data.

Times mark interval starts in UTC, from October 2025 through September 2026. The CSV retains load, solar and wind generation in MW; wind combines the published onshore and offshore values.*

## Work with this example

Keep `report.rmd` and the [CSV observations](data.csv) together in one folder. To inspect generation, use `load_mw`, `solar_mw` or `wind_mw` as `encoding.y` and change the value-axis label and unit to MW.

```sh
richview generate report.rmd
```

Use zoom and keyboard or pointer inspection to read a specific interval. The chart's Table and CSV actions show the fields used here; the CSV above retains every original column.
