Xcel Energy to improve capacity, reliability

Xcel Energy is set to spend $24.7 million on a multi-year project to improve the reliability and capacity of the electric transmission system that serves Portales, according to an Xcel press release.

“The existing system is just not capable of sustaining the kind of growth we’ve seen and the additional growth we expect to see,” said Riley Hill, president and CEO of Southwestern Public Service Company, an Xcel Energy company, in the press release.

Over the next five years, Xcel Energy plans to upgrade the 69-kilovolt system to 115 kilovolts, creating a transmission loop around the city to improve service reliability.

These projects include:

  • South Portales-to-Kilgore 115 kilovolt line: More than two miles of new 115-kilovolt line will be built to connect the existing South Portales and Kilgore substations in the southeast corner of Portales. The South Portales Substation will be upgraded from 69-kilovolt service to 115-kilovolt capabilities. Total cost is estimated around $5.8 million, with an in-service date of June 1, 2018.
  • South Portales-to-Market Street 115-kilovolt line: Almost two miles of new 115-kilovolt line will be built between the South Portales and Market Street substations in southwest Portales. Both substations will be upgraded from 69-kilovolt service to 115-kilovolt capabilities. Total cost is estimated around $4.5 million, with an in-service date of June 1, 2017.
  • Market Street-to-Portales 115 kilovolt line: Seven miles of new 115-kilovolt line will be built between the Market Street and Portales Substation in northwest Portales. Existing 115-kilovolt equipment in the Portales Substation will be upgraded, and 69-kilovolt equipment in the Market Street Substation will be upgraded to 115-kilovolt capabilities. Total cost is estimated around $14.4 million, with an in-service date of June 1, 2017.
