Youre also forgetting another component which is that the instrastructure gets torn down or stolen because it has market value. The replacement, maintenance, and security of wired grids is likely higher.

Why would infrastructure get torn down once it’s in place?

Copper wire has high resale value. So do solar panels. Copper theft is a problem worldwide, including the US.

The local militia or government wants money and doesn't care overmuch about the locals themselves, presumably.

You seem to have conveniently forgotten about centuries of colonialism, resource exploitation and state-sponsored regime changes, which still plague Africa today.

How would you differentiate Africa from East Asia in those regards?

1) se asia is a much more densely populated region, making infrastructure cheaper per capita to produce (some things scale better, most do not) and 2) se asia has capital flowing through it at a far higher volume, mostly because of manufacturing.

I can't speak to why there historically hasn't been as much manufacturing in Africa—I'm guessing it's just cheaper to colocate with others for lower costs across the board?

Regardless, (neo)colonialism does dominate both regions—it's a hard state to avoid if you want to interact with a global economy at a deep financial disadvantage.

It's been obvious for a long time this was going to be the development path for Africa. Just as they leapfrogged land line telephones for cellular. Africa was never going to build out massive coal and natural gas based electrical grids with transmission lines substations and utility poles bringing electricity to every home. The capital isn't there and the cost of renewables keeps falling.

Because they failed to maintain or invest in a regular grid. Off-grid, battery-backed is far more expensive than generator-backed at scale… at least for now. And you still need generators for poor weather.

I recently bought 4 lifepo4 12v 100ah ~1200 wh for $159 off Amazon as a retail customer. Battery storage is indeed cheap and accessible to the average person. Pair it with new 24% efficient solar panels and you can see why there's little to be gained by running expensive lines to distribute power when it can be sent everywhere wirelessly.

It's not too different to how developing counties rolled out wireless Internet and gained a huge benefit without much infrastructure investment.

Small pet peeve - saying "Africa" is too broad a statement for a continent with 54 countries, and does a disservice to the actual government institutions working on development.

They should explicitly call out Nigeria instead of treating it as "Africa". Nigeria is unique in how they actually have a formal industrial strategy for mini-grids [0] thanks to World Bank support [1]

It's a uniquely Nigerian program and Nigeria's Rural Electrification Administration (REA) should be given it's due credit. When Boko Haram does something bad it's "Nigeria", but when Abuja does something good it's "Africa".

Finally, what works for a federal state with a relatively strong civil service like Nigeria cannot be replicated in every "African" country, due to entirely different administrative and bureaucratic norms and capacity.

Grids are better if you have the capital to build them. Most of arfica has been too unstable to safely invest in. Everytime things start looking up there is another revolution and all investment is lost.

Of course with the large number of countries there, that generalization is false. But it is overall close a enough to true.

Mini-grids may be the part the EU is missing. Selling your surplus ev power to grid is a huge waste, charging your neighbours car is a better use.

But with mini grids you'll just end up with over supply during sunshine/wind with nobody at all to sell the excess to

Indeed, and that is current state; renewables and battery manufacturing continues to ramp, which will encourage further cost declines. This is objectively good, it democratizes low carbon, cheap energy.
