The invention relates to the technical field of an electric power transaction platform, and provides a method for implementing an electric power transaction based on an electric power transaction platform. The method comprises the steps that an electric power transaction server receives an electric power transaction request of an electric power enterprise terminal or a power utilization enterprise terminal; a supervision center server processes the electric power transaction request and generates an electronic transaction contract and information publish authority passing information; the electric power transaction server parses the electric power transaction request, acquires transaction information parameters and generates and publishes electric power transaction information; the electric power transaction server receives transaction confirmation request information sent by the power utilization enterprise terminal and the electric power enterprise terminal and controls the power utilization enterprise terminal and the electric power enterprise terminal to complete signing of the electronic transaction contract and corresponding expense settlement; and the electric power enterprise terminal is controlled to generate an instruction for transmitting electric power to a user enterprise corresponding to the power utilization enterprise terminal, thereby realizing intelligent electric power transaction, meeting transaction requirements of electric power enterprises and the power utilization enterprises, and conforming to development requirements of electric power system reform.
