"Thermal dams" make sense?

Brazil is blessed with multiple and robust hydrographic basins.

Even so, the choice of our official directors in the electricity sector fell due to expanding the number of thermal plants, - much more expensive - and which today already have a relevant proportion in our power matrix.

The result is well known. The cost of Brazilian energy has become the most expensive among the BRICS (Brazil, Russia, India, China and South Africa).

To make matters worse, thermal plants generate much more emissions than hydroelectric ones.

With the expansion of solar and wind energy in our power matrix, the need for back up power plants to accommodate their intermittency, becomes even more important.

It would be great if a comparison was made of what would be best for the country in technical, financial, environmental terms between the thermal plants and the contracting of plants with important reservoirs (and not the ones without dams as has been the preference).

Robust decision-making processes are the initial step towards achieving and maintaining competitiveness - so necessary for Brazil.

I´d like to know more about these "thermal plants".  Sounds ominous. Is there any further information available?

Hi Mark,

Actually I designated "thermal dams" as opposed to what would make more sense, which is having hydro reservoirs to feed hydro power plants which of course are a lot cheaper than thermalpowerplants since they do not involve fuel (which in Brazil is quite expensive).

So "thermal dams" is an expression I created just to identify this crazy situation!

Thanks. I guess I should have come to that conclusion myself!
