Daily grid recaps
Shortly after midnight UTC we freeze a recap of the day that just ended: the biggest event, how much electricity each market used, the cheapest and the most expensive hour, and how long prices stayed below zero. Each recap is built once from the operators’ published data and is not changed afterwards, so later revisions by the operators do not appear. Days without a negative-price spell of an hour or more, a price spike or a new wind high are marked as calm days and are kept out of search results. Every number carries a badge that says whether it is metered, derived or estimated.

How the events are chosen
A recap shows up to three events, biggest first. Below zero: the longest unbroken spell of negative prices in one market, only when it lasted at least an hour. Price spike: the highest hourly price of the day, in US dollars, when it reaches 300 dollars per megawatt-hour or three times that market's median hourly price over the previous 30 days; the median rule needs at least 14 days of our own history. Wind high: a wind or renewable-share peak above everything in our own data, only once that data covers 14 days. The cheapest hour is always shown but never makes a day notable.
Totals add up only markets with at least 95 per cent metered coverage of the day; the others are listed as partial. See the methodology.
