Ponderosa to Grimes 230kV Transmission Line

Type: Transmission
Scope: 40 miles of 230kV
Location: Montgomery, TX

Client: Entergy

Irby Construction was awarded the Ponderosa to Grimes Transmission Project as a construction partner to Dashiell Engineering in September of 2015. Dashiell is also a member of the Quanta family of companies, and Irby was a proud partner on the project.

This project was located near Montgomery, TX and included 40 miles of 230kV line consisting of both steel and concrete poles. Construction addressed both future load growth and current reliability needs in Entergy Texas’ western area. It also cleared congestion in the Grimes substation area.

Irby Construction worked with subcontractors Auger Services for the foundation work on site, and enlisted helicopter services from fellow Quanta company, Winco, to pull lead line and help clip the shield wire. 

This project was successfully completed in April 2016.
