SPP Board of Directors approve 2018 ITPNT Assessment [free access]

July 31, 2018

The Board of Directors of the Southwest Power Pool (SPP) have approved the 2018 Integrated Transmission Plan Near-Term (ITPNT) Assessment report, an annual evaluation performed to assess the requirement of system upgrades at various voltage levels in the near term, in order to address the reliability needs in the region.

 

The plan has mentioned 13 new transmission upgradation projects across six states over the next five years with a net investment of USD47.4 million. They have been proposed to resolve the anticipated grid reliability needs arising out of the future consumption requirements and announced generation retirements in eastern Kansas and western Missouri.

 

The identified projects include capacitor bank installation at the 69 kV New Lakeview substation, reconductoring of the 115 kV Richland–Lewis line, transformer replacement at the 230/115 kV Lawrence Hill and Sundown substations, construction of the 161 kV New Blue Valley–Crosstown line, replacement of terminal equipment on the 161 kV Olathe–Switzer, 115 kV Carlisle–Murphy, 115 kV Clauene–Terry County and 161 kV Brookridge–Overland Park lines, reactor installation at the 345 kV New Brookline substation, rebuilding of the 69 kV Nixa Downtown–Nixa Espy and Figure Five–VBI North lines, and construction of the 230 kV New McDowell substation. The projects are expected to provide voltage stability, reduce grid congestion, and ensure the region’s compliance with the mandatory federal standards.

 

Besides the above, SPP has abandoned six previously approved projects worth USD84.6 million, with the involved investment of approximately USD85 million. These include installation of the 69 kV Blanchard and Ringwood capacitor banks, 230/115 kV Dean Interchange station and transformer, and rebuilding the 345 kV Jeffrey–Hoyt, 138 kV Welsh Reserve–Wilkes and 138 kV Chapel Hill Rec–Welsh Reserve line projects.

 

The projects were removed from the plan since SPP assessed that they were no longer needed to support the grid. Further, the Board’s actions are expected to have no net impact on the monthly bills of the average residential customer across SPP’s regions.


The initial draft of the plan was prepared on June 21, 2018.
