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
SPP.org 4
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
• 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• 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• 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
