Mid State Transmission
This project addresses regional energy challenges and opportunities:
- Improve system reliability and resilience
- Modernize grid to meet growing energy demand
Project Summary
The Mid-State Transmission Project is a proposed upgrade to PNM's existing transmission system in Torrance, Socorro, and Valencia counties. The Project includes construction of a new 345-kV transmission line. Much of the proposed Project's route will utilize existing PNM rights of way, with new rights of way options utilized to account for technical, environmental, cultural, land-use, and public input.
Route Evaluation
Cultural & Environmental Considerations
Preserving cultural heritage is a shared responsibility that begins with meaningful collaboration and continues through respectful planning and protective action. This framework outlines key principles that guide efforts to engage communities, honor sacred spaces, and safeguard cultural resources throughout development and construction processes.
