Get on the Ercot page with your house info, and you can see your usage throughout each day. Maybe it would sum up time-of-day info over a year? Whether a plan is good for you depends on how much time you spend around your house in the days in the summer, or how flexible you can be. Night/weekend plans don't work for me since my wife works from home, and now I do half the time too. So gotta keep the a/c frosty all day. Also, in a house with not a great a/c and crappy ducts, I can't let it get hot since then it takes too long to get comfy again.
What kind of rates are you seeing for the paid hours? If it's low enough, then it might be worth it. Gotta do the math. Maybe with more people stating home, there have been fewer folks using the weekends/night, so electric company deals may be getting better since they really want people to get off peak.
Previously when I have looked, the paid hours had been $0.20 or higher, which didn't make sense when I'm at $0.085/kwh all-in, with 3 year fixed contract.
If I had about 5 Tesla Walls that I could fill up each night with free juice, then run off it all day, that would be cool. Of a giant reservoir to pump water up to, etc.
