SPP to issue notifications to construct for certain transmission upgrades during week of Feb. 13

The names of the entities that proposed transmission projects that were recently approved by the Southwest Power Pool (SPP) are confidential, and as for those that will eventually build those projects, SPP will issue notifications to construct during the week of Feb. 13, an SPP spokesperson told TransmissionHub on Feb. 10.

The SPP board, at a Jan. 31 meeting in Dallas, approved construction of the portfolio of upgrades recommended as part of SPP’s 2017 Integrated Transmission Planning (ITP) 10-Year Assessment, or ITP10, SPP said in a statement.

The board approved 13 out of 14 transmission upgrades recommended in the ITP10 assessment and directed further evaluation of a new 345-kV line from Potter to Tolk in the Texas Panhandle, SPP said, adding that SPP staff is expected to report on the further evaluation in April.

SPP noted that the ITP10 portfolio of projects is intended to reduce congestion in some of SPP’s most historically constrained areas, such as west Texas and southwest Missouri; enable more efficient delivery of clean energy resources and optimize use of SPP’s most efficient conventional resources; as well as better enable SPP to reliably operate its regional transmission system in accordance with mandatory reliability standards.

According to a presentation that was given at the Jan. 31 board meeting, the 90-mile Potter-Tolk 345-kV line is in the Southwestern Public Service (SPS) area, and its estimated cost (2017 dollars) is $144m. The lead time for the project is 72 months, and the need date listed in the presentation is Jan. 1, 2017.

The spokesperson noted that the “area(s)” noted in the presentation refer to the transmission owner areas wherein the project will be built, not who proposed or sponsored the project.

In all but one case – the Potter-Tolk line – it is safe to assume the owners will be those listed in the presentation, as they do not meet the criteria specified in FERC Order 1000 that would require them to be competitively bid, the spokesperson said.

As noted in the presentation, the approved projects are:

  • The estimated $12m, Tolk/Yoakum-Cochran/Lehman Tap and 230/115-kV “xfmr” project in the area of SPS; the lead time for the project is 24 months, and the in-service date is June 1, 2018
  • The estimated $10m Hobbs/Yoakum-Allred/Waits Tap and 230/115-kV xfmr project in the area of SPS; the lead time is 24 months, and the in-service date is June 1, 2017
  • The estimated $9.5m, Morgan 345/161-kV xfmr + line uprate project in the area of Associated Electric Cooperative Inc., (AECI); the lead time is 36 months, and the need date is listed as Jan. 1, 2017; the spokesperson said that the project will require an agreement with AECI, which “is not a member of SPP, because it will require their construction”
  • The estimated $7.5m, Woodward 138-kV “PST” project in the area of Oklahoma Gas and Electric (OGE); the lead time is 18 months, and the in-service date is June 1, 2017
  • The estimated $7.4m, Seminole 230/115-kV double xfmr replacement project in the area of SPS; the lead time is 24 months, and the in-service date is June 1, 2017
  • The estimated $5.2m, 2.1-mile, Siloam Springs-SS City 161-kV rebuild project in the area of American Electric Power (NYSE:AEP)/Grand River Dam Authority; the lead time is 24 months, and the need date is listed as Jan. 1, 2017
  • The estimated $3.4m, one-mile, new Knoll-Post Rock 230-kV line in the area of Midwest Energy; the lead time is 24 months, and the need date is listed as Jan. 1, 2017
  • The estimated $1m, Tuco-Stanton-Indiana-SP-Erskine 115-kV terminal upgrades project in the area of SPS; the lead time is 18 months, and the need date is listed as Jan. 1, 2017
  • The estimated $0.7m, Martin-Pantex-Highland 115-kV terminal upgrades project in the area of SPS; the lead time is 18 months, and the need date is listed as Jan. 1, 2017
  • The estimated $0.5m, Northeast-Charlotte 161-kV “2 ohm reactor” project in the area of Kansas City Power & Light; the lead time is 24 months, and the need date is Jan. 1, 2018
  • The estimated $0.2m, Butler-Altoona 138-kV terminal upgrades project in the area of Westar Energy (WR); the lead time is 18 months, and the need date is listed as Jan. 1, 2017
  • The estimated $0.1m, Neosho-Riverton 161-kV terminal upgrades project in the area of WR/Empire District Electric; the lead time is 18 months, and the need date is listed as Jan. 1, 2017
  • The estimated $0.1m, Tupelo-Tupelo Tap-Lula 138-kV terminal upgrades project in the area of OGE/Western Farmers Electric Cooperative; the lead time is 18 months, and the need date is Jan. 1, 2020

In a separate document regarding the ITP10, SPP said that the recommend portfolio is expected to provide value to the SPP region in any one or combination of three reasonably likely future scenarios: a future in which entities in the SPP region collaborate to reduce carbon (“Reduced Carbon Future 1”); a future in which entities in the SPP region work within their respective states to independently achieve carbon reduction (“Reduced Carbon Future 2”); and a “business-as-usual” future in which environmental and public policy requirements remain unchanged from today (“Reference Future”).
