Records
The figures on this panel are real, sourced records. They're currently hand-entered and checked periodically against the sources below, rather than computed automatically from stored history - each record's "last checked" date shows when it was last verified.

Get a browser notification when price or carbon intensity crosses a threshold you set. This only works while this page stays open in a browser tab - this site has no server that sends push or email notifications, so closing the tab (or the browser) turns alerts off until you reopen it.
Checked against live data roughly every 5 minutes while this page is open, plus once whenever it first loads. Your thresholds are saved in this browser only (not sent anywhere) and only fire once per crossing, so you won't get repeated notifications while a value stays past your threshold.
