TNMP Pilot Point 138kV Transmission Line Project

TNMP filed an Application to Amend its Certificate of Convenience and Necessity (CCN) with the Public Utility Commission of Texas (PUC) on June 9, 2023.

Supporting Our Growing Communities

TNMP is planning for transmission line upgrades to improve electric reliability for customers in Collin, Denton, and Grayson Counties. The Pilot Point 138 kV Transmission Line Project is anticipated to connect the proposed Pilot Point Substation, located approximately 0.2 miles east of the intersection of United States Highway 377 (US 377) and East McDonald Drive in Denton County, to the existing 138kV transmission system in Collin, Denton, or Grayson Counties.

This area of North Texas is one of the fastest growing residential areas in the entire country, and the Pilot Point project is necessary to support growth in the area. This transmission line project will directly support the area's residential and commercial development and ensure reliable electric service to commercial and residential customers.

Structure Types

Two transmission line structures would be constructed as part of the Pilot Point project: a double circuit tangent braced post and a double circuit, two structure dead-end. The anticipated right of way for either structure is approximately 80 feet.

Project Schedule

We're currently in the regulatory review phase of the project. We anticipate filing a Certificate of Convenience and Necessity (CNN) with the Texas Public Utilities Commission in June 2023. Regulatory approvals will continue through late 2023, followed by Right-of-Way (ROW) activities, engineering design and material procurement. We anticipate construction to begin in early 2025. The schedule is subject to change and is dependent on right-of-way acquisition and supply chain.
