How to reduce power costs in Brazil?

70 million Brazilian households consume an average of 170 kWh/month of electricity.

It is equivalent to an average consumption of 0.2 kWh/h.

The electric shower - a typically 5 kW load - represents about 25% of monthly residential consumption - is used for about half an hour a day. Especially in the early morning and early evening.

Although it consumes only 40 kWh/month it generates a peak of 5 kW. But... the national integrated electrical system needs to be sized to meet this peak

The residential rate structure does not capture this reality because it charges only kWh consumption. As this cost exists, it is passed on to "the others".

One of the explanations for the Brazilian energy cost being the highest among the BRICS (Brazil, Russia, India, China and South Africa) is, surely, this one of the shower.

For every million showers turned on simultaneously during peak hours, a demand of 5 GW is generated. The national demand is 80 GW.

It is high time to seek cost efficiency. Anyone wishing to explore this opportunity, just get in touch!
