With the reform of power system and the development of energy Internet industry

developing integrated energy service will be an important direction of business transformation of power enterprises. Focusing on the mining and application of power supply companies’big data

such as electricity load

electricity quantity

payment and so on

from 3 dimensions of customer credit

customer value and customer risk

an integrated energy project mining and cultivation evaluation index system is constructed. The index system includes 9 specificmdicators

such as monthly average pre-deposit ratio

monthly average times of arrears

and monthly average times of power outage. Optimization strategy of integrated energy project based on fuzzy evaluation is proposed

which uses big data to evaluate the internal conditions of potential customers

thus providing certain support for mining high - quality potential customers. Finally

taking 8 random customers for the case study

the results show the effectiveness of the method based on the project evaluation index system.
