3. State Grid Of China
State Grid is another state-run energy company in communist China. In 2019, it grossed $387,000,000,000. The company formed about the same time as Sinopec, when the communist government reformed its energy sector in the 1980s. Unsurprisingly, it has a monopoly on the Chinese power grid, and it runs regional power grids throughout the country.
It may be surprising that State Grid also runs power grids in other countries, including Brazil and the Philippines. Some of their grids are run under different names; even in China, five different companies fall under State Grid. State Grid could easily continue to see its revenue increase and its international market growth, especially if it switches to renewable energy sources, such as solar, hydro, and wind, to power its grids.
