Does Angola benefit from a natural protection system?

The Angolan power system benefits from a “natural protection” given that the two summer quarters (January to June), with greatest demand, are also those with highest hydroelectric production. The last quarter of the year is the one with the least hydroelectric production being necessary a higher usage of natural gas power plants.

How much power will Angola have in 2025?
