nothing is less certain, such projects encourage the development of a country's "technological culture" in cutting-edge sectors. Is it negligible?For example, there are 3 solar power plants in Morocco, a 4th is under construction Nothing FOR EXPORT. As it stands, it therefore exclusively benefits the country. There is a positive point is that Morocco must overcome the problems of terrorism but the risks are much less important than for nuclear power. The blow of the kilowatt-hour is about 30% more canceled than expected but it remains anecdotal. Concentrating power plants will be required to meet the load factor. I think that in the end, the solution will be that the inhabitants who want power by "wasting it in the evening" or at night, will pay the price it will take... So much more expensive, which will bring in these installations in black numbers. Otherwise and more economically, individuals who can, will afford batteries for buffer storage (even with their own solar installations on their roofs...) And finally, as my uncle said, stop the frantic way of life, "the night is made for sleeping..."
I would see the development of Na-ion batteries in these areas? I don't know what our specialists think about it.
Indeed, several developing countries, with the financial and scientific help of the developed countries, are quite able to assimilate the technological leap represented by these new energy processes.
In a non-exhaustive way, I can quote 2 of them: in Morocco, since 2011, was created the IRESEN, with a rather broad vocation, turned towards Africa.

As for the production of electricity by thermodynamic solar power plant, the current costs are of the order of 10 c$ / kWh for the most recent projects.
In addition, in the USA, a new objective of 5/6 c$/kWh for 2030 was announced, for power plants with towers and adjustable mirrors with more than 10 hours of storage. It is the same as the one announced in 2006 by the Spaniards for their important program of that time.
We will eventually manage to have a night current in the big cities of countries with a latitude of less than 40° at a cost that individual batteries will find difficult to compete with!
