I am from Nanchang University (undergraduate, unified recruitment), and our school is: each dormitory (four people in one dormitory, two fluorescent lamps, two fans, and a small lamp on the balcony).
According to the provincial regulations, each dormitory generates 160 kwh of electricity every year, which exceeds the 0.6 yuan per kwh.
School electricity is based on the residential electricity price, so it should be 0.6 yuan. Your school charges are too high. You can report to the competent unit of your school (usually the Provincial Department of Education).
