I lived in Nigeria 2006-2012. Their electric grid is run by the government. It was called the Nigerian Electric Power Authority, NEPA, or as locals called it No Electric Power Again, or Never Expect Power Again. It was built by the Brits decades ago. It fell apart over the years due to government waste and corruption. Billions poured into that system and siphoned off by officials.the countries with public utilities have grids that are decades ahead of ours
I lived on Ikoyi Island and both apartments that I lived in had two large diesel generators with huge diesel storage tanks. We would go weeks without grid power, just running a generator. They would switch gens everyday at noon. When we were occasionally blessed with grid power, the voltage would fluctuate so badly that electronics would become unstable and sometimes would blow out light bulbs. I would never choose to have a state run power grid.
