What if the power supply bureau goes bankrupt?

You made a lot of mistakes. First, the previous power supply "bureau" was a public institution. Institutions will not "fail". Only enterprises will fail. Second, around 2002, China's power system was reformed and power plants and power grids were separated. It should be called "power supply company" now It is impossible for the power supply companies of State Grid and China Southern Power Grid, which can be seen in Chinese mainland, to close down. Only by reorganizing assets, or one day restructuring, changing its name, saying it differently and changing its appearance, is it possible. But the management institutions of power supply network and distribution network will always exist. How can you still use electricity?
