Seems like in such a case, it should be a different mix of base fixed monthly bill versus usage based rates, to more accurately reflect the cost structure in play.

For example, in my area it’s about $15 a month even if you use absolutely no electricity, that’s just the base charge ostensibly for the infrastructure required to deliver power, should you want it. It might make sense for this number to be increased rather than raising $/kwh rates.

Suppose the counter would be that at least with the rate increase, folks in more dire circumstances can cut back to avoid the increasing costs (which might be a bit of a feedback loop…)
