Document Description
Note: FINAL The Palermo-East Nicolaus 115-kV Transmission Line is an existing double-circuit tower line that carries two individual 115-kV circuits between the applicant's Palermo and East Nicolaus substations. Both circuits would be reconductored. To accommodate reconductoring, replacement of the existing lattice steel towers would be required. The existing Milliken towers, originally constructed in the early 1900s, wuld not support the new conductor because of higher tension loads. The towers would be replaced with a combination of hybrid tubular steel poles, tubular steel poles, and lattice steel poles. A capacity increase to the system would result from the replacement of existing copper conductor with 1113 All Aluminum conductors for each circuit from the Palermo Substation south to Rio Oso Junction and with either 1113 all-aluminum or 457 steel-supported aluminum cable conductor from Rio Oso of the lines and eliminate forecasted line overloads. In addition, a limited number of towers on a single-circuit line, the Palermo-Pease 115 kV Transmission Line, which runs parallel to the Palermo-East Nicolaus 115-kV Transmission Line, would be replaced for consistency with the spans on the Palermo East Nicolaus 115-kV Transmission Line. Construction would take 12 to 18 months.
