A portion of Downtown Spokane’s electrical grid, the Metro East Network, is nearing full capacity. With load increases expected, reliable service near the network’s edges may be difficult to provide. Currently three feeders run from the Metro substation to the Metro East network. Avista Utilities asked us to design a fourth feeder to remove stress from the other three feeders and increase capacity. Adding additional cable underground poses problems from a heat-transfer perspective, so a significant portion of our efforts were spent analyzing the network from a thermal point of view. Our proposal will keep Downtown Spokane powered while maintaining the safety and reliability of an electrically robust and mechanically sound network.
