Generally speaking, there is no need to sign a power supply contract with a third party. If it is necessary to sign a contract with a third party, it is because the third party participates in management. Generally, the electricity price is high, and the third party buys electricity from the power system and sells it again. In this case, it is necessary to sign a contract with a third party. Therefore, Hangzhou Electric Power signed a contract with a third party because of its participation in management.
