Lampasas-San Saba 138kV Transmission Line Construction Project

Type: Transmission
Scope: Constructed 33.4 miles of 138kV transmission line including poles and foundations.​
Location: Lometa, Texas
Client: Lower Colorado River Authority

The Lower Colorado River Authority (“LCRA”) is a non-profit public utility providing wholesale power to over a million people in Texas. In December 2016, LCRA contracted Irby to construct 33.4 miles of 138kV transmission line from Lampasas to San Saba in central Texas.

The project was executed in consideration of a condensed LCRA schedule and habitat-specific environmental permitting requirements. The Irby scope included steel structures, poles, 22 drilled pier foundations, and a railroad and major highway crossing.

With assistance from fellow Quanta Services subsidiary company North Houston Pole Line (Irby is also a Quanta Services subsidiary (PWR:NYSE)), the project was successfully delivered to LCRA in January 2018.

Start Date: December 2016
Completion Date: January 2018

Hurricane Irma Emergency Power Restoration

Type: Emergency Restoration
Scope: Performed emergency power restoration services throughout Florida in the wake of Hurricane Irma.
Location: Florida, USA

On 10 September 2017, Hurricane Irma made landfall on Florida’s Atlantic seaboard. The storm caused significant damage to power transmission infrastructure resulting in a loss of power to over 6 million Floridians.

Irby crews, attending emergency restoration activities on the Gulf Coast as a result of Hurricane Harvey, adapted deployments to provide needed specialist personnel and equipment to restoration efforts in Florida. By months end, power had been restored to pre-storm output levels.

Start Date: September 2017
Completion Date: September 2017

Hurricane Harvey Emergency Power Restoration

Hurricane Harvey Emergency Power Restoration

Hurricane Harvey Emergency Power Restoration

Type: Emergency Restoration
Scope: Performed emergency power restoration services throughout the Gulf Coast in the wake of Hurricane Harvey.
Location: Gulf Coast, USA

Hurricane Harvey was a category 4 storm which made landfall on the United States Gulf Coast in August 2017. The storm caused substantial damage including electricity outages resulting from high winds and significant flooding.

At its peak, forced outages displaced more than 10,000 MW of electricity generating capacity within the Electric Reliability Council of Texas grid including six major 345kV transmission lines and more than two hundred 69 kV–138 kV lines. As Harvey made landfall, caravans of Irby specialist personnel and equipment were mobilized so the power restoration process could begin as soon as the rain and winds subsided.

Alongside many fellow Quanta Services companies, Irby teams logged 114,000 manhours restoring power to impacted communities.

Start Date: August 2017
Completion Date: October 2017
