Greetings friend good article, I do not have much to contribute on the subject, but I call my attention because in country Venezuela the national electricity network currently goes through very difficult times, and some areas of the country tend to ration electricity for several hours because it does not generate enough energy.
I observe the diversification that exists in the national electricity network that you mention, there are many alternatives some better than others but seeing them as a whole there is an ideal complement to keep the system always active.
So long, my friend, have a great week!
