Time of use rates are wrong in Brazil


Time of use rates are wrong in Brazil

The chart shows a typical recent week day with demands of the integrated national electric power system.

The highest demands (columns in red) occur in the middle of the afternoon, when the rates are cheaper ("off-peak")

In this scenario, consumers transfer their consumption, as much as they possibly can, by seeking off-peak rates..

By doing so, the (real) peak of the system is being intensified, aggravating costs and burdening the whole society.

We must change and urgently. On peak rates should be tied to the times when the maximum demands of the system occur. This is the basic, plain and simple definition of on-peak and off-peak.!

We have a regulator (ANEEL), an independent system operator (ONS), ministry of mines and energy (MME) and a power clearinghouse (CCEE). All official institutions. Are they "for real" or just "on paper"? Do their executives know about time of use rates and have the capacity and knowledge to take the necessary actions?
