How the What Electricity Costs Right Now screensaver works

The saver reads the source described above and draws it on a canvas — no account, no tracking.

The Octopus Agile half-hourly tariff, read live and key-less. Agile passes the wholesale day-ahead price straight to the household, so the curve has a real shape — a teatime peak, an overnight trough, and on windy nights a genuinely negative price.

It refreshes on a schedule, so what you see stays current.

Colours and any options can be changed in settings; nothing is stored beyond your own browser.
