Energy (Brazil): golden opportunity!

Energy: golden opportunity!

The 80 million homes in Brazil have 90 million electric “instant” showers, which is their biggest load for the vast majority of them.

So what?

An electric shower requires around 5 kW. If there is half an hour of shower per day in each household, consumption will be 75 kWh/month, about half of the total monthly power consumption.

I repeat the question: so what?

Each house demands an average of 0.2 kW from the grid but for half an hour a day, at least 5 kW.

And so the sizing of the production chain in the electrical sector needs to consider at least 5 kW of load.

This is exactly where there is an opportunity: replacing these “instant” showers with “accumulation” showers.

And what would be the benefit?

Each kW demanded costs around USD 3 000  in CAPEX investment across the entire electricity sector production chain (generation, transmission and distribution).

The proposed replacement would have the potential to “save” investments of around 3 kW per shower, that is, USD 9 000. This value is large enough to make the replacement viable and still leave a good margin that could be “distributed” as a reduction in tariffs.

And how much are we talking about?

Each million instant shower operating simultaneously replaced would generate gross savings of USD 9  billion.
