Southern California Edison has a similar thing I think as well.
78 isn't that bad though inside, especially when outside it was 118 where I live in Central California. We have our house set to 76 currently, and I think I would be fine with 78 once I acclimated as long as it stayed mostly consistent throughout the house.
74 and below is often to cold for the inside especially for my parents and it also just makes venturing outside a bit worse as well when there's over 30 degrees difference between the inside and outside
That's just wild to me. I'm in the UK and we rarely ever set ours in our house over 58. Any more than that and it feels uncomfortably hot.
