PIVOT OVERVIEW Desert Southwest Region - 10-Year Plan 5 See Page 7 of Handout Book
Pivot Goals • The Pivot is a two part process which will align the 10-Year Plan with the budget formulation schedule • Federal budget formulation occurs two fiscal years in advance of the current year • After the Pivot is complete, prepayment funding will be voted on for projects that occur two years out from the current year • This differs from the historical prepayment voting schedule, which involved voting on projects for the current fiscal year Desert Southwest Region - 10-Year Plan 6
Pivot Schedule • The Pivot will be conducted across two 10-Year Plan annual cycles • The Pivot began January 2018 and will conclude with the prepayment vote in December 2019 • The December 2018 and December 2019 votes are anticipated to fund prepayment projects proposed through FY22 Desert Southwest Region - 10-Year Plan 7
Pivot Benefits • Improved budgeting and execution of prepayment dollars • More opportunity for customer engagement in the Analysis of Alternatives (AOA) Study Process • Customer engagement will include: • Input on identifying mission critical projects • Input on the alternatives to be analyzed in the study • Input on the selected alternative • The Pivot provides customers additional opportunities to review and discuss projects in advance of the prepayment vote in 2019 Desert Southwest Region - 10-Year Plan 8
SEED FUNDING EXPLAINED Desert Southwest Region - 10-Year Plan 9 See Page 8 and 9 of Handout Book
Seed Funding Explained • Historically projects utilized an estimate generated during the AOA Study Phase • Higher accuracy estimates are generated in the Seed Funding Phase • The Seed Funding Phase has the benefit of detailed engineering design and preliminary environmental/geological assessments • The objectives of seed funding are to: Produce a design package to 50%-75% completion Fund the project through the first year of preconstruction Refine the scope, schedule and estimate from the AOA Study Phase Advance an AOA Study Phase design through preliminary design Desert Southwest Region - 10-Year Plan 10
Seed Funding Explained • Each project scope is unique and the amount of seed funding required to produce the first year design varies • Any funds (prepayment or appropriations) designated for the Seed Funding Phase, but not spent, will be retained and utilized on the project as it progresses Desert Southwest Region - 10-Year Plan 11

FY19 SEED PROJECT BOUSE UPGRADE AOA Study Phase: September 2018 Seed Funding Phase: October 2018 Desert Southwest Region - 10-Year Plan 15 See Page 11 of Handout Book
Bouse Upgrade Project Overview • The Bouse Upgrade Project is WAPA’s next seed funded project • The seed funded design phase will begin in October 2018 and concludes in September 2019 • This project will be proposed for prepayment funding in December 2019 • Appropriations have been secured for FY19 to begin the Seed Funding Phase for preliminary design • The details of the Bouse Upgrade Project were shared during previous 10-Year Plan Meetings • The purpose of the project is to resolve the ongoing delays and issues encountered on the Parker-Headgate/Parker-Bouse Project (PAD-HDR/PAD-BSE) • For detailed information regarding this project please see your handbook on page11 • You can also visit WAPA’s 10 -Year Plan website at: https://www.wapa.gov/regions/DSW/Pages/10-year-capital- program.aspx Desert Southwest Region - 10-Year Plan 16
2018 Prepayment Funding Vote Desert Southwest Region - 10-Year Plan 17 See Page 19 of Handout Book
2018 Prepayment Funding Vote Desert Southwest Region - 10-Year Plan 18
2018 Prepayment Vote There are two “types” of projects proposed for prepayment funding this December • Seed Funded Projects • These projects have completed a seed funded design phase and reached a 50%-75% design • The scope, schedule and estimate of these projects has been refined • The use of prepayments to fund the projects is being voted on in December • Pivot Project • This project is being funded in order to align with the budget formulation • The scope, schedule and estimate are based on the AOA study that was completed in 2016 • The project estimate has been updated with current labor rates • As the project moves through preliminary design the estimate accuracy improves and will be shared in detail with the customers Desert Southwest Region - 10-Year Plan 19
BOUSE-KOFA 161-KV REBUILD PHASE I & II AOA Study Phase: September 2016 Prepayment Vote: December 2018 Desert Southwest Region - 10-Year Plan 20 See Page 19 of Handout Book
Bouse-Kofa 161-kV AOA Study Project Overview • The AOA study was completed in the summer of 2016 • The study has been revalidated in anticipation of the upcoming prepayment vote • The original study encompassed an 84 mile segment of the Parker-Gila transmission line, which was built in 1943 • The transmission line is comprised of 82 wood H-Frame structures and 211 light duty steel H-frame structures • In 2006, an 8.4 mile section of the line was rerouted around the town of Quartzite with 954 ACSR on steel monopoles • This portion of the line is not included in the project Desert Southwest Region - 10-Year Plan 21
Bouse-Kofa 161-kV AOA Study Project Justification Lineman Climbing Safety • 106 NERC/NESC violations require Concerns corrective action • Significant deteriorated and unsafe wood structures • Vintage 1943 300 kcmil hollow core copper conductor experiencing significant sag Checking / Heart Rot • Access roads and Right Of Way (ROW) require rehabilitation • 20-30% of wood poles require replacement immediately • Additional communication bandwidth is required via fiber optic ground wire to meet current and future protection, control, communication, and security requirements Desert Southwest Region - 10-Year Plan 22
Bouse-Kofa Approximate Phasing • The original study was performed under the assumption that the project would be pursued as a single construction project • During revalidation of the study it was decided to split the project into 2 separate phases • As a result of this phasing transmission rate impacts are moderated • Phase I • ~31 miles of rebuild from Kofa Substation heading north • Phase II • ~44 miles of rebuild from Bouse Substation heading south Desert Southwest Region - 10-Year Plan 23
Bouse-Kofa Rebuild Scope • Reconductor with 336.4-kcmil ACSS to reduce sag, eliminating the majority of the NERC/NESC violations • The existing copper conductor has an estimated salvage value of ~$1.7M, which was taken into account in the estimate • Upgrade the remaining 82 wood structures to light duty steel H-frames • ~5-10 replacements will be dead-end structures • Additional steel structures may be needed to correct any remaining NERC/NESC clearance issues • Add Optical Overhead Ground Wire (OPGW) • Repair/Reclaim ROW access Desert Southwest Region - 10-Year Plan 24
