Return on demand. According to Polaris Power Network, Turpan's government subsidy for electricity charges is to subsidize users in the form of "return on demand". The power supply company will calculate the financial subsidy when charging electricity on a monthly basis 1 day. For remote fee control users, financial subsidies will be directly returned to the balance of users, and for local fee control card users, they will also be returned to the card area to be written. When the user purchases electricity next time, it will be charged to the electricity purchase card together with the amount of electricity purchased, and it will be recharged to the user's electricity meter remotely.
