(2) Electricity for crop cultivation and post-harvest processing: electricity for crop sowing, seedling raising and cultivation management or processing machinery for drying, threshing, washing, grading and packaging of various agricultural products, or light and temperature regulation required for facility gardening Those who use electricity and have certification documents or agricultural machinery usage certificates issued by the municipal or county (city) competent authority.
(3) Electricity for refrigeration and grain storage of agricultural products: refrigeration of agricultural products by farmer groups and agricultural product wholesale markets, or electricity use by farmer groups for warehousing operations of public grains, rice, and miscellaneous grains or rice milling machinery, and shall be subject to the supervision of municipalities and counties (cities). The certification document is issued by the government agency or the food authority.
(4) Electricity for aquaculture: on-shore feed raw material storage, freezing, mixing, feeding, and net washing machinery required for offshore aquaculture, and those who have obtained a fishery rights license or fishing right certificate. Electricity for water quality improvement equipment such as water pumping, drainage, air pumping, greenhouse heating, circulating water, feed raw material storage, freezing, mixing, and feeding machinery required for land-based farming, and those who have obtained a breeding and fishery license.(5) Livestock electricity: electricity used for raising livestock, poultry, pollution prevention and control facilities, egg washing, grading and packaging, or milk collection station machinery, and certificates issued by the municipal or county (city) competent authority.
4. Residential electricity consumption
Residential electricity consumption refers to urban and rural residential buildings and their ancillary facilities (referring to corridor lights, residential building elevators, water pumps, street lights in communities and villages, property management, doormen, fire protection, garages) and other domestic electricity; Ordinary colleges and universities (including universities, independent colleges and technical schools), high schools (regular high schools, adult high schools), secondary vocational schools (including general technical secondary schools, adult technical secondary schools, vocational high schools, and technical schools), junior high schools (ordinary junior high schools , vocational junior high schools, adult junior high schools), primary schools (ordinary primary schools, adult primary schools), kindergartens (nursery schools), special education schools (institutions that implement compulsory education for children and teenagers with disabilities) school teaching electricity and student living electricity; nursing homes, Electricity is used for adoption and shelter service places that provide accommodation, such as orphanages and rescue management stations; electricity is used for street lights, tap water and non-profit public activity places below the rural public transformer (former rural comprehensive transformer).
2. Calculation method:
1. Calculation method of electricity bill for large industrial use:
Electricity bill = basic electricity bill + kWh electricity bill + power adjustment bill.
(1) Basic electricity fee = power consumption × basic electricity price
Power consumption capacity: transformer capacity or maximum demand ① (The user chooses the billing method, and the basic electricity price is inconsistent between the two selection methods)
Basic electricity price: various regions Electricity prices are inconsistent. Taking Shandong as an example, if the electricity capacity is calculated based on the transformer capacity, the basic electricity price is 28 yuan/kVA; if the electricity capacity is calculated based on the maximum demand, the basic electricity price is 38 yuan/kVA. If the actual used capacity is insufficient When 40% of the maximum demand is reported, 40% will be charged. If the demand exceeds the maximum demand, the basic electricity fee will be doubled (76 yuan/kVA).
(2) Electricity fee = Electricity quantity × Electricity price
Electricity quantity: The electricity measured by the electric meter (peaks and valleys are measured separately), read by the meter every month.
Electricity price: refer to the two-part electricity price part of the following table (Shandong Provincial Power Grid Sales Price Table, Shandong Provincial Power Grid Transmission and Distribution Price Table):
(3) Adjustment of electricity charges: Adjust electricity charges in accordance with the "Power Factor Adjustment Measures for Electricity Charges".

2. General industrial and commercial electricity, agricultural production electricity Calculation method for electricity and residential electricity bills:
Electricity bill = electricity consumption × electricity price.
Electricity: Electricity measured by the electric meter, read by the meter every month.
Electricity price: refer to the following table (Shandong Province Power Grid Sales Price Table, Shandong Province Power Grid Transmission and Distribution Price Table):
3. Interpretation of the contents of the electricity bill details
Total electricity bill = basic electricity fee + electroplating electricity fee + force adjustment electricity fee + fund total
Note:
① Maximum demand: The maximum demand refers to the average power of the customer's electricity consumption during a certain period of time (currently 15 minutes in my country) within a certain settlement period (usually one month), and its maximum one-time indicated value is retained as this The maximum demand for a settlement period.
