DESCRIPTION OF PROPOSAL: Larson to Moses Lake 115 kV Transmission Line Rebuild.
Public Utility District No. 2 of Grant County, Washington (Grant PUD) owns and operates a 115 kV transmission line between its Larson and Moses Lake Substations, located in Moses Lake, WA. The 3 mile line was constructed around 1946, uses wood H-frame structures and is nearing the end of its useful life.
Grant PUD proposes to replace the line with a new, single wooden pole line located 30 feet west of the centerline of the existing line’s right-of-way. The new 115 kV line will be designed for a single 13.2 kV underbuild circuit with a neutral and a single all-dielectric, self-supporting (ADSS) fiber optic cable. The first half mile out of the substation at each end of the line will include an overhead static wire.
The wood pole tangent structures will have polymer horizontal post insulators for the 115 kV conductors and 9’ wood cross-arms for the 13.2 kV conductors. The distribution conductors will be supported by porcelain vertical posts. The dead-end structures will be guyed wood poles.
The line follows Stratford Road on the east side and transverses pasture and residential lands. Terrain is generally flat. Existing distribution and secondary taps and services will be transferred to the new poles where applicable.
