Zenith-Franz Project
Proposed 138 kV Transmission Line in Harris County

Why is the proposed transmission line needed?
The Zenith-Franz project is part of an interrelated set of improvements that are needed to improve the reliability of the electric transmission system and serve the projected load growth in the Katy area located in Harris County near the interchange of Interstate Highway (IH) 10 and State Highway (SH) 99, known as the Grand Parkway.

Proposed Project
CenterPoint Energy proposes to construct a new 138 kV double-circuit transmission line, connecting an existing 138 kV transmission line to the existing CenterPoint Energy Zenith Substation located in northwest Harris County.

Who must approve this project before it is constructed?
The Public Utility Commission of Texas (PUC) must approve this project before it is constructed. The PUC will determine the best route for the proposed 138 kV transmission line while considering whether the proposed transmission facilities are necessary to serve the public. CenterPoint Energy prepared an application for a Certificate of Convenience and Necessity (CCN) for the proposed 138 kV transmission line project and submitted it to the PUC on February 12, 2015 under Docket No. 44242 for review and approval. The deadline for intervention in the proceeding is March 30, 2015.
