How "green" is the Brazilian power matrix?

The significant increase in the share of wind energy and the potential for solar energy growth bring new challenges too!

I refer to the power production per month of 1 kW of installed nominal capacity. It is of the order of 50% for wind and 20% for solar. As a reference, the hydroelectric power is around 70%.

The independent system operator needs to readily make capacity available whenever the source in question requires it. To illustrate, the solar demands- at the end of the day - a fast transition that has presented a significant additional cost for those countries that have made this source "massive". It is the "duck curve".

This discussion is not new. It has been referred to as "capacity x energy". The increased use of wind and solar sources tend to increase the demand for capacity. This is a cost that needs to be recognized and allocated!
