Don't get too excited, that is the worst bill of the year by far being July and every day >90f with my wife home all summer. Most bills in the low to mid 300's and 3 or 4 a year in the 180-250 range.
No tiers, just a slightly higher rate in the summer. There are PV incentives in Md but I already have the prime 30% or so of my roof covered in solar water panels for the pool. Not really interested in a PPA. Kind of interested in an outright purchase, maybe in the next couple years as prices fall a little more.
