About Power for the Plains

The Power for the Plains transmission expansion is a series of transmission line projects that Xcel Energy is upgrading or building in its Texas and New Mexico service area aimed at expanding and updating the electric grid to improve reliability, meet demand and provide new renewable energy outlets.

As part of Power for the Plains, Xcel Energy has invested in over 800 miles of new transmission lines since 2011 in New Mexico, Texas and Oklahoma. More than 700 additional miles of transmission line is planned to be constructed through 2021. Since 2011, over 30 new substations have been built and nearly 40 others upgraded. Another 27 substations will be built or upgraded through 2021. The transmission expansion represents more than $3 billion in investment.


2010 - The Southwest Power Pool Inc. (SPP) approved a series of new Xcel Energy transmission lines spanning portions of Texas, New Mexico and Oklahoma, to help improve electric reliability, strengthen the existing transmission grid and provide outlet for additional renewable wind generation.

2013 - Xcel Energy began promoting an effort known as the High-Priority Incremental Load Study, which was approved by the Southwest Power Pool in April 2014 resulting in 44 new transmission projects for Xcel Energy to build within its New Mexico and Texas service areas. These projects represent a $557 million investment in new high-voltage transmission lines and substations through 2020.

The plans called for 400 miles of new high-voltage transmission lines and 12 new substations, primarily in eastern New Mexico and West Texas. These projects were in addition to more than $60 million in new transmission facilities approved by Southwest Power Pool in February 2014, as well as 240 miles of new, lower-voltage distribution lines that deliver power directly to customers, mostly in Lea and Eddy counties.

Xcel Energy works with the Southwest Power Pool on a continual basis to plan for transmission projects to meet the needs of customers and ensure reliable electricity. Often these scheduled studies result in additional projects to be constructed by Xcel Energy.
