Increasing complexity

The Power Operation Plan report, recently released by the National System Operator, shows the Brazilian electricity sector from 2020 to 2024.

It is an interesting and even easy read because it is an executive summary.

Our generation matrix has become more diversified. Solar and wind (intermittent sources) gaining importance.

But...the Brazilian matrix was not designed for the flexibility that intermittency requires.

For the time being this theme has not "appeared" since these sources were and still are only a small, marginal slice of the "cake". But with its advances, it will be desirable to find out how to address this challenge competitively.

Our tradition of just passing on to the costs paid by everyone would be terrible because we are already laggards when the comparison is with the BRICS (Brazil, Russia, India, China and South Africa).

"But...the Brazilian matrix was not designed for the flexibility that intermittency requires."

No matrix was designed for the flexibility that intermittent solar and wind require, Rafael. That leaves grid planners with two options: 1) spend a fortune on batteries, transmission, and new gas plants to try to accommodate unreliable energy, or 2) use reliable energy - available hydropower and nuclear.

In theory, you could power Brazil by paying millions of citizens to pedal stationary bikes with generators. But why?

My suggestion is facing the new challenges (such as those originated by the duck curve) and come up with options to mitigate this "new animal" in a competitive fashion.
