Proposed evolution of the power rate structure 

If you contract NETFLIX, a mobile phone plan, a car subscription - it is about a fixed monthly fee for each. It doesn't matter if you watch 50 films or none, talk all day on your cell phone or practically don't use it, drivel 1 thousand miles a month or stay quarantined at home. 

The reason is simple. The fixed charge reflects the biggest cost involved: the amortization of the invested capital...that is fixed per month.

With electric power, I suggest, the same approach. The monthly charge to be predominantly fixed, depending on the capacity demanded by the customer. Reason: the electricity sector is essentially capital-intensive.

An example.

Suppose a house has 3 instantaneous electric showers of 5 kW each and another that has a central heater of accumulation of 3 kW, to meet the same demand of baths. The two houses have the same monthly consumption of 500 kWh.

One house has a demand from the public grid of 15 kW (the three showers operating simultaneously) and another of 3 kW. The difference in investments required to serve the two houses is 5:1. But the current system does not identify this reality because it bills the same 500 kWh for both houses.
