The invention relates to the technical field of electric power Internet of Things, and particularly discloses a dual-mode Mesh networking method for the electric power Internet of Things, which comprises the following steps: firstly, defining that an MWWP node is simultaneously connected with a wired Mesh network and a wireless Mesh network, and then packaging a protocol message, so that an HWMP routing protocol can be transmitted in the wired network. Then, through self-defining an MWWP wired information frame on a wired link between the MWWP nodes, a mapping relation table from the wireless MAC address of the opposite-end MWWP node to a local wired port is constructed; after the MWWP node receives the data to be forwarded, whether the data can be directly forwarded from the wired port is determined according to the bridging table, if not, whether the data can be sent from the wired port is further determined according to the routing table and the mapping relation table, and if not, the optimal forwarding pa
