In Australia/Perth we have a "Daily Supply Charge".
We also have one of the higest rates of residential rooftop solar here, you get relatively little payback for exporting in Perth (its hard to get more than about $20/month) but can save quite a bit on what you self-consume during the day.
As a result, this Daily Supply Charge has been steadily going up over the last decade, much more than the per-unit fee. Currently it's $1.13 AUD/day + $0.316/kWh (that's 74c USD/day + $0.21 USD/kWh)
Looking at how cheap LFP batteries are getting and people not getting much for feeding back into the grid from their solar installs I think battery pack sales are about to rocket. Australia is in a very unique situation with a lot of land, big potential for solar and wind.
These charges are quite high compared to most places in the US. I pay somewhere around 11 or 12 cents USD per kWh and around 50 cents per day in a connection fee (in reality, it's 15 per bill and not adjusted for the number of days being billed).
