This work analyses the Economic Dispatch of the power generated from the Proposed Nigerian 330KV integrated network using ETAP 12.6 software and the result simulated by Matlab software. The result obtained revealed that not all the generating stations of the Proposed Nigerian 330KV network will be in circuit during optimal power flow. The generating stations that are out of circuit are thermal power stations. This reduces the cost of generation, waste as well as saves energy from the installed capacity of generation. The result further reveal that the real and reactive transmission losses in the entire network is reduced to 45.41MW and 257.98MVar respectively.
