Hub Substations - Idaho Power

Questions from Meeting #5Q: Are there reasons a corner is more/less desired than notbeing on a corner for distribution substations?A: Yes. We plan distribution substations to have 8 feeders (13.8kV) fed out of them, two heading each direction. If thesubstation is not on a corner, four feeders will have to be fedeach direction until an intersection is reached. It creates a lotof congestions. Additionally, a distribution substation willneed two 138 kV lines feeding into it so that also adds tocongestion. Idaho Power prefers street corners for the samereason gas stations do; access to four directions of travel froma single point.ETVEP Mar2012
