are daily tiers and dynamic pricing really needed for consumers, shoudn't it even out on the long term? Until recently it worked quite well for a energy supplier to supply me with a fixed rate for a year and still making profit (when I take a look at their yearly earnings report, I think I also subsidized heavy users with my low usage :D). over a year the price should average out quite nicely when I look at the energy mix in germany and the cost. The only "problem" we currently have is the merit order principle and the pegging of the (haywire) gas price to the energy price which makes calculations for suppliers difficult (and the absence of building renewable, and the maintenance and shutoffs of nuclear :D). Aside from that consumption is quite foreseeable and production also, so daily rates should not matter that much? I think paying by the hour/daily makes things just more complicated, I actually don't really want to time my laundry cooking with future prices on an hour/daily base :D
