Solar: what now (Brazil)?
Solar energy has become an important source of the Brazilian power matrix.
A problem identified in countries that have massively introduced solar energy has been the “duck curve” – during maximum isolation levels, an imbalance arises.
There is more supply than demand.
It gets to the point that the price of solar energy exported via the public grid becomes negative!
The approach adopted – in California (USA) – was to make a storage system (batteries, for example) mandatory to receive this “extra” energy and then use it when there is no sunshine.
When will Brazil “wake up” to this issue?
Or, in the best “Tupiniquim” style, will we first let the problem emerge and then “see what to do”?
