we gathered it

Both lines are set to 100 at 1 Nov 2024, the first day they share, so they can be read against each other. That is division — nothing here is smoothed, filled in or forecast. The number above the chart is still the real one.

Midcontinent ISO Illinois hub averaged $74.58 a megawatt-hour over the month. That is 42% more than last week and 62% more than a year ago.
