German electricity prices also turn negative
A year of day-ahead prices at 15-minute intervals, with load, wind and solar in the downloadable snapshot.
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.

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 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.
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.
