Recently, large-scale snowfall and freezing weather have caused transmission lines to freeze. Why is there a power shortage? The power is out now.

1. Due to the weather, it is difficult to transport electric coal. Without coal, thermal power plants can't generate electricity.

2. Winter is a dry season, and the power generation of hydropower plants is correspondingly reduced.

When the weather is cold, the electricity consumption will increase greatly, resulting in insufficient electricity consumption, even in summer.

4. The recent bad weather caused the line to freeze and jump, which in turn led to tower collapse and disconnection, or more trips. There is something wrong with the transmission line, and even electricity can't be sent away.
