Hub Substations - Idaho Power

Questions from Meeting #5Q: Can we get TVEP explanations for why they selected proposedsites for both substations and distribution substations?A: The TVEP did not site any distribution substations. They onlysited 500 kV source and 230 kV hub substations. The TVEPCAC followed the criteria they developed and sited the hubsubstations using already existing distribution substationproperties when available or tried to site the substations awayfrom population centers when possible. They also tried to sitethe hub substations near existing 230 kV transmission. TheTVEP CAC sited the source substations as far away frompopulation centers as possible while realizing a number of230 kV transmission lines would need to feed out of thesubstations.ETVEP Mar2012
