PNM's proposed transmission line route through Valencia, Socorro, and Torrance Counties

A free, printable guide explains what PNM proposes, how the state approval process works, and how Torrance County residents can take part.

The Public Service Company of New Mexico (PNM) and Pattern Energy plan to build a new 345-kilovolt transmission line, just over 100 miles long, across Torrance, Socorro, and Valencia counties. Much of it would follow PNM's existing power line, but it would need a right-of-way up to 200 feet wide. For landowners along the route, that could mean a wider easement across their property. For everyone else in the Estancia Valley, it means a major piece of infrastructure moving through the region over the next several years.

Most of the decisions about the line will be made by the New Mexico Public Regulation Commission (PRC) in Santa Fe. Its process can be hard to follow from the outside. It works more like a court than a town council, uses its own vocabulary, and sets deadlines that come early. The Mountainair Dispatch has put together a resident's guide to help.

What Is in the Guide

The guide is free to download, print, and share. It covers:

  • What PNM has proposed, including the route, structure heights, and PNM's stated schedule
  • How the Mid-State line relates to other regional energy projects, including SunZia, Western Spirit, and Pattern Energy's Bolo Transmission line
  • The two separate questions state law asks: whether a line is needed, and where it should go
  • Where things stand in PRC Case 26-0000114, where Mid-State is already being discussed (and in future cases relevant to Mid-State)
  • How a PRC case moves from application to final decision, and who does what along the way
  • How residents can comment, attend hearings, follow the case online, and contact PNM and the PRC
  • A plain-language glossary of the terms that show up in PRC filings, from "CCN" to "motion in limine"

Why It Matters Now

As of October 10, 2026, PNM had not yet filed its separate applications asking the PRC to approve the need, location, and width of the Mid-State line. When that case is filed, the deadline to ask to intervene, which is how residents and organizations become formal parties, usually comes early. Knowing how the process works ahead of time makes it much easier to take part when it counts.

The information in the guide is current as of October 10, 2026. The Dispatch will update it as the case develops.
