A tale of two Norways

Monthly average power price in Norway's five bidding zones since January 2022: a built-in line plot. In the 2022 energy crisis (shaded), the south paid more than 100× what the north did.

How it's built

Pipe a CSV into the CLI and pick a type:

cat monthly.csv | novem -p power-monthly --type line -C

The styling is plain-text config:

config/colors: warm hues for the south (NO2, NO1, NO5), cool for the north (NO3, NO4), in the data's column order
config/axis: yearly ticks, light gridlines, top padding, and the 2022 band (x 2022-01:2023-01 fill:#fdf3ea,#33261c)
config/marks: 2px lines with a dot on each latest value
config/legend/*, config/title, config/caption

Kept live

The render step of the strompriser job (job/main.py in the onboarding repo) rewrites the data twice a day from the strompriser space: a dataset of Nord Pool day-ahead prices that the job's ingest step keeps current. Prices come from the free hvakosterstrommen.no API, in NOK/kWh excluding VAT and grid tariffs.
