Is it a property responsibility for residents to use electricity without changing the national grid?

It should be the responsibility of the property company that the residential area has not been changed to the national grid. Because the property management company is responsible for the daily operation and management of the community, including the management and maintenance of infrastructure such as power supply, water supply and gas supply. If the residential power supply is not connected to the national grid, it may be that the property management company is improper, or the power supply transformation project is not completed.

But the specific situation may be different, and it may also be affected by some other factors, such as the size of the community, geographical location, the actual situation of power supply and so on. So if you have any questions about this question, I suggest you directly contact the property company in the community or the local power company to ask about the specific situation, and they will give you a more accurate answer.
