The reason why the electricity charge is expensive is mainly because of the funds and extra expenses it contains. These fees are usually set as the relevant provisions of national policies and must be charged together with electricity charges. For example, the resettlement fund, surcharge and Three Gorges construction fee are all included in the electricity fee collection, which further increases the user's electricity consumption on the basis of electricity fee.

However, it should be emphasized that charging electricity is not the same as ordinary electricity. Ordinary electricity charges are mainly used to pay basic expenses such as power production and transportation, while the electricity charges collected include additional funds and additional fees, which are mainly used to support the maintenance and development of power systems and pay for some special projects or services.

Generally speaking, the electricity charge is expensive because it contains extra funds and additional expenses, which are collected together with the electricity charge. However, these expenses are very important for the maintenance and development of power system and the support of some special projects or services.
