Priority Project Update

Bruce Rew

Vice President, Engineering


Priority project overview
Priority Project Overview

  • Commitments to Construct have been received from all Transmission Owners

  • Westar Energy, Mid-Kansas Electric Co., and Sunflower Electric Power Corp. propose Novation to Prairie Wind and ITC Great Plains

  • Routing changes surrounding Medicine Lodge

    • Environmental/ Right-of Way issues

  • Cost Estimate changes

    • Multiple causes, including re-routing, reactive support, and refining project scope within shared projects


Nebraska city maryville sibley
Nebraska City - Maryville - Sibley

  • KCPL GMO and OPPD Project Updates

    • Added reactive support to updated project estimates

      • Addition of reactive support has caused increase in cost for both KCPL GMO and OPPD

    • KCPL GMO forecasted contingency for higher labor, material, equipment costs

      • Estimates are preliminary due to limited design work, siting and procurement activities

    • OPPD has refined project scope and updated project estimates

      • Uncertainty of line route and river crossing/ROW issues increases cost estimate


Hitchland woodward
Hitchland - Woodward

  • OGE and SPS Project Updates

    • SPS and OGE divided construction at approximately 30 miles for SPS, 90 miles for OGE

      • Original OGE estimate contained total 120 miles of project

      • SPS estimate lower than original OGE estimate for their 30 mile section

    • SPS estimates are preliminary

      • Limited experience in double circuit 345kV construction


Woodward comanche county medicine lodge
Woodward - Comanche County/Medicine Lodge

  • MKEC and OGE Project Updates

    • Routing Changes due to environmental concerns

      • Woodward line proposed to terminate at Medicine Lodge instead of Comanche County

        • Line to move eastward and increase by approximately 40 miles

      • Additional line length causes significant cost increase

    • Proposed Novation of portions of project to Prairie Wind and ITC Great Plains

      • Prairie Wind will be involved in line construction, ITC Great Plains for substation


Spearville comanche county medicine lodge wichita
Spearville - Comanche County - Medicine Lodge - Wichita

  • MKEC, SUNC, and WR Project Updates

    • Proposed Novation of portions of project to ITC Great Plains and Prairie Wind

    • Added reactive support to project estimates

      • ITC GP Substation costs increased with new reactive compensation

        • ITC GP still optimizing studies

    • Routing changes for new substation in Wichita

      • Prairie Wind estimates additional 5 miles of line to substation

        • Increased cost for additional line and substation


Priority projects unchanged
Priority Projects Unchanged

  • NW Texarkana – Valliant

    • No changes proposed by AEP

  • Tulsa Reactor

    • No changes proposed by AEP



Updated b c ratio
Updated B/C Ratio

  • Original cumulative B/C = 1.78

  • Based on new cost estimates, Cumulative B/C = 1.58
