For those who look for electricity price data, they will find conflicting information.
CCEE (Electric Energy Trading Chamber)
The price for TODAY (June 6, 2025) shows a practically constant value of R$ 320/MWh. Regardless of the time of the day.
ONS (National System Operator)
The daily demand curve published by the ONS shows a large variation throughout the day. And it also shows that the peak in the summer occurs in the middle of the afternoon. In the other months, it occurs in the late afternoon.
ANEEL (regulator) The (regulated) tariffs granted to electricity distribution companies establish different values for "peak" (end of the day/beginning of the night) and "off-peak".
Of course, each of these institutions has its own calculation methodology. And they certainly respect it. But the "whole picture" is inconsistent. It makes decision-making processes, based on established criteria of good engineering, difficult.
