This project is intended to upgrade/rebuild Avista’s 26 mile section of the Benton – Othello Switching Station 115kV Transmission Line with conductor capable of a continuous 120 MVA loading (205 MVA limit capacity). The reconductor/rebuild will include a crossing of the Columbia River. Planning studies show overloading of the existing transmission lines thermal rating during specific outages in Grant PUD's Transmission System. The Construction window for phases 2 and 3 will straddle fiscal years 2015-2016 and 2016-2017, with construction tentatively scheduled for December 2015 through March of 2016, and November 2016 through March 2017. A significant portion of phases 2 and 3 are on federally owned property, complicating the permitting process. (2) Devils Gap - Lind 115kV Transmission Line: Line Rebuild (ER 2564, BI ST302) Region: Davenport (Manager: Cesar Godinez) Reconductors and Rebuilds Designer/Engineer: CAI Consultants with Aaron Tremayne as Project Manager (x2178) Area Engineer: Tim Figart Area RBM: Steve Trabun/Paul Kimmell Area RE Representative: Larissa Pruitt Construction Window: 2014-2017 (Spring/Fall) Construction Forces: Spokane Operations/Contract Scope: 2016: Phase 3 design and procurement. 2017: Phase 3 construction. This project is intended to rebuild 65% of the Devil's Gap to Lind 115kV line with new steel structures. Replace all larch on the line, and those cedar structures needing replacement or repair based on condition assessment from the last inspection in 2009. While no load growth or planning projects are expected in the near future, this line requires extensive repair and replacement work. Over half of the line's structures are larch wood material, now at the end of its expected service life. Also, the area subject to recurring ice loading failures will be addressed. 2016-2017 work will address the area from a point south of Sprague to a point near Reardan.
