New Mexican here. I also lived in California in the desert, in Indio, where daytime temperatures routinely hit 115-120 with nighttime lows of 98 during the summer. It was a fairly big house with two AC units. Our electric bills were high there, naturally.
Since moving back to New Mexico, I have a smaller house and only one AC unit. Even with lower sustained temperatures, our electric bills are as high or higher than what we paid in the desert in California.
If and when Blackstone takes over from PNM, I don't know how we'll continue to afford electric. It's just greed, greed, greed.
