What changes with the hourly spot?

The free market started many years ago in Brazil, and the differences in power consumption versus contracted volumes are calculated in three hourly segments, aggregated per week.

From now on, it is calculated by the hour. It will better reflect what happens in real life.

The hourly spot is - of course - more "volatile". It means that free consumers must follow and, if necessary, act. There are three possible situations regarding the comparison between contracted and consumed volumes:

  • They are coincidental - which is very rare! Nothing to do!
  • There are surpluses - will be settled automatically by the official power clearinghouse
  • There is need to contract a volume 

The first step is to see the hourly consumption curve of your company or institution and compare it with the contracted volume.

The second is to analyze this curve and find out the alternatives to minimize the costs associated with the differences between contracted volumes and actual power consumption hour by hour.
