The challenges of intermittence
Solar and wind energy have gained super importance in the Brazilian power matrix.
At the same time, new problems emerged... to be solved. Simply put on a day when the sun doesn't "show up" the electric power supply chain needs to “show up.”. And/or, of course, when there is a lull in the winds.
Technically it's simple. It is enough to have generation plants, transmission and distribution lines as "back up" to deal with intermittency.
And so what?
The desirable action is to evaluate the associated investments that need to be remunerated to make these intermittency related arrangements viable. This is because intuitively it is easy to understand that these backup plants will have a "dispatch" that will not make them very competitive as they will be available basically "when necessary".
As long as there is no robust, balanced accounting that makes the system isonomic for all consumers, Brazil will maintain an unpredictable, expensive and unfair regulatory framework.
Or is the ongoing situation "okay"?
