PJM: Board authorizes more than $417m in electric transmission projects for reliability

PJM Interconnection on July 26 said that its Board of Managers has authorized more than $417m in electric transmission projects for reliability, including the replacement of a large and outdated substation that serves healthcare buildings, government, education, transportation centers, and other critical infrastructure customers in Newark, N.J.

The $275m Public Service Electric & Gas (PSE&G) Newark Switch substation project replaces aging equipment, PJM said, adding that a new substation adjacent to the existing structure was determined to be the most cost-efficient solution. While relocating the substation was also considered, that would have been a more costly solution and posed more risk, PJM said.

PJM also said that its board approved equipment upgrades and improvements in areas served by American Electric Power (NYSE:AEP); Dominion Energy (NYSE:D); Exelon’s (NYSE:EXC) Atlantic City Electric and PECO Energy; FirstEnergy’s (NYSE:FE) Pennsylvania Electric Company and American Transmission Systems, Inc. (ATSI); East Kentucky Power Cooperative (EKPC); and Dayton Power & Light.

According to PJM, the approved projects include:

  • The estimated $31m “b2871,” which involves rebuilding the 230-kV line #247 from Swamp to Suffolk (31 miles) to current standards with a summer emergency rating of 1047 MVA at 230 kV; the owner is Dominion, and the required in-service date is Dec. 30, 2022
  • The estimated $19.9m “b2898,” which involves reconductoring the Beaver-Black River 138-kV line with “954Kcmil ACSS” conductor and upgrading terminal equipment on both stations; the owner is ATSI, and the required in-service date is June 1, 2021
  • The estimated $13.5m “b2897,” which involves reconductoring the Avon-Lorain 138-kV section and upgrading the “line drop at Avon” – the owner is ATSI, and the required in-service date is June 1, 2021
  • The estimated $5m “b2826.1,” which involves installing 300 MVAR reactor at the Ohio Central 345-kV substation; the owner is AEP, and the required in-service date is June 1, 2018
  • The estimated $3.2m “b2896,” which involves rebuilding/reconductoring the Black River-Lorain 138-kV circuit; the owner is ATSI, and the required in-service date is June 1, 2021
  • The estimated $1.7m “b2875,” which involves relocating the Richland to Ridgeville 138-kV line from Richland J bus to K, extending the K bus, and installing a new breaker; the owner is ATSI, and the required in-service date is June 1, 2019

Most of the individual projects cost less than $5m, PJM said in its statement.
