 locations in demand by the time of day and season. So this is basically seasonal electricity demand by hour for the PJM system, right? So it's the mid-Atlantic and sort of midwestern grid that we're a part of. And so basically what you can see is that in the fall and the spring are kind of like boring for the electricity industry. Everybody can just kind of go to sleep. And demand tends to be higher in the summer and the winter. For the PJM system as a whole, it sees its highest level of electricity demand in the summer. There are some areas of the US that are what we call winter peaking, that they see their highest level of electricity demand in the winter. So like Pennsylvania was a winter peaker for decades, up until sort of the last 10 or 15 years. And actually the northwestern corner of Pennsylvania was still winter peaking. But places like Minnesota are winter peaking states. And so the demand for electricity and the cost of providing electricity also varies by the time of day. And so the PJM system, it tends to see a peak in the sort of mid to late afternoon. In the winter, the daily pattern of electricity usage changes a little bit where you have a kind of a double peak where there's a peak in the morning and then there's another peak in the afternoon. That's a good one. That is not a good one. I can fix this in the next one.
