What will happen if you don't pay the overdue notice?

The question doesn't explain what the cost is, but here it is explained by not paying the electricity bill on time.

After the end of the electricity payment period, the power supply enterprise will send the arrears reminder notice to the arrears customers according to the process, and the arrears related person will take photos or sign it. If the electricity fee is not settled within the time limit specified in the notice, measures to stop and limit electricity can be taken according to the prescribed procedures.
