Jefferson Davis Electric Cooperative 230KV T-Line System Loop Upgrade

Jefferson Davis Electric Cooperative 230KV T-Line System Loop Upgrade

Project Type: Transmission and Distribution
Scope:
Upgrade approximately 105 miles of 230kV T/L with UB Distribution on several sections.
Location:
Lake Charles, LA
CLIENT: Jefferson Davis Electric Cooperative (JDEC)

Irby is working in collaboration with several Quanta operating units to complete approximately 105 miles of JDEC transmission line that have been damaged from previous storms, the worst of which was Hurricane Laura in August of 2020.

The existing system is a combination of 69kV and 138kV lines that run through two Louisiana parishes. Irby’s work will upgrade these lines to a 230kV system to support future growth in these communities.

The on site team is jacking structures at the point of receipt that will then be delivered assembled to the right-of-way. There are more than 1,300 structures to complete.

Crews are also conducting wire stringing operations (both transmission and distribution under build), erecting structures in all marsh areas, and assisting with underground work at three water crossings.

The two biggest challenges on this project have been what crews have unofficially (but appropriately) labeled the two “big Ms” of Louisiana— mud and mosquitoes.

Start Date: July 2023
Completion Date: In Progress

Florida Power & Light Underground Lateral Hardening

Florida Power & Light Underground Lateral Hardening

Florida Power & Light Underground Lateral Hardening

Type: Distribution, Underground Design-Build
Scope: 3-year distribution overhead and underground maintenance.
Location: Bradenton, Florida
Client: Florida Power & Light

Severe weather events pose a significant risk to community electrical infrastructure. Local authorities in Florida have prioritized grid development strategies to offset this risk via the increased burial of electrical transmission lines. To this end, Florida Power and Light (FPL), an industry-leading energy utility serving over 10 million customers in Florida, has allocated resources exceeding $4 billion for new and upgraded underground electrical infrastructure throughout its service area, 47% of which is currently underground.

FPL contracted Irby in April 2019 to provide ongoing technical support services related to customer outreach, engineering design, construction, and maintenance of several of these underground assets. For its pilot community project, 100% homeowner approval was required to enable the diversion of above ground FPL lines using Irby’s conduit, HDPE, and pad-mounted underground equipment solutions. To avoid outages, the work was performed while energized, with one circuit route totaling ~1.6 miles of 13.8kV distribution line delivered within a 45-day work schedule and with zero lost-time incidents. Irby’s directional boring solution was ideally situated for the scope allowing for minimal excavation and environmental impact to residential properties.

With strong community support, Irby and FPL have already carried out 8 “Storm Secure” projects together in and around Sarasota and Manatee counties with planning underway for at least 85 additional deployments.

Bozeman Road Distribution Project

Bozeman Road Distribution Project

Bozeman Road Distribution Project

Type: Distribution
Scope: Constructed 6.6 miles of 13.8kV distribution line.
Location: Madison, Mississippi
Client: Entergy Mississippi

In support of future energy demand near Madison and Hinds counties, Entergy Mississippi (450,000+ customers in 45 counties) contracted Irby in May of 2017 to deliver 3 additional circuit routes to the Bozeman Road 230kV radial substation. To avoid outages, the work was performed while energized, with circuit routes totaling 6.6 miles of 13.8kV distribution line.

The work was completed to schedule and with zero lost time incidents using Irby’s conduit, HDPE, and pad-mounted underground equipment. Irby’s directional boring solution was ideally situated for the Entergy scope allowing for minimal excavation and minimal impact to the surrounding site.

Start Date: May 2017
Completion Date: October 2017
