Overhead Distribution

Project Type: Overhead Distribution

Scope: Approximately five miles of overhead distribution line conversion and pole replacement

Location: Mount Pleasant,  South Carolina

Client: Dominion Energy Southeast (SC)

Start Date: Early 2018

Completion Date: Fall 2022

Outside of Charleston, South Carolina, the city of Mount Pleasant set out to widen Clements Ferry Road, a high-traffic roadway accomodating commuters in and out of Charleston. With the expansion of the road came upgrades to the accompanying infrastructure, including power lines.

The project required collaboration between road construction crews and contractors in various industries: water, sewer, gas, paving, and department of transportation, along with Sumter Utilities who was tasked with replacing more than 100 poles and wire.

With so many moving parts along a high-traffic area, clear communication, attention to detail, and coordination were critical. Sumter was assigned one point of contact to coordinate with other contractors to ensure that work could happen seamlessly. It was like a dance, where every move was choreographed in detail to avoid delays.

Sumter Utilities foreman spoke with other contractors on the job daily, sometimes even hourly. Three crews worked around rush hour traffic and other key players to ensure that the job was completed safely and on time.

Yemassee Rebuild & Conversion


Project Type: Transmission

Scope: Rebuild 20+ miles of 115kV single circuit transmission line and convert a single wood-pole 115kV line to single steel poles.

Location: Yemassee / Lady’s Island / Beaufort, South Carolina

Client: Dominion Energy Southeast (SC)

Start Date: March 2019

Completion Date: May 2021

Sumter Utilities was contracted by Dominion Energy Southeast (SC) to rebuild 20+ miles of 115kV single circuit transmission line. Additionally, Sumter was to convert a 115kV line from single wood poles to a single steel pole, double-circuit bundle configuration. Located in the areas of Yemassee, Beaufort, and Lady’s Island, South Carolina, the project was nestled within low-lying wetland and tidal areas, presenting substantial terrain challenges. Additionally, Sumter Utilities was tasked with installing vibratory caisson foundations on all the structures, some driven to depths of fifty feet in the ground. By utilizing matting in tidal areas, collaborating effectively with a variety of subcontractors, and pivoting the plan after a vibratory caisson refusal, Sumter rose to the challenge, driving the project forward to success.

The Sumter Utilities team demonstrated exceptional performance for this $22M project. As the primary contractor, Sumter met the schedule with zero power interruptions and zero injuries. Transmission and distribution joint efforts made this project successful for everyone involved, and Dominion Energy was very pleased with Sumter’s ability to deliver.

Underground Distribution

Project Type: Underground Distribution

Scope: 2,000 ft of Overhead to Underground conversion

Location: Solomon’s Island, Maryland

Client: Southern Maryland Electric Cooperative

Start Date: 2021

Completion Date: May 2022

Sumter Utilities was contracted by Southern Maryland Electric Cooperative to complete a three-phase conversion of overhead distribution to underground distribution along Solomon’s Island Road, a popular tourist destination for the Baltimore-Washington Metro area. The distance stretches approximately 2,000 feet from the historic Lore Oyster House to Patuxent Avenue.

This project includes a complete turn-key solution for the conversion, including duct bank installation, primary and secondary cable installation, conversions and cut-overs, street light install, cable terminations, and restorations. The beginning of the project spans an open causeway, with the design including a carrier pipe over the 24 feet of waterway.

Together with our subcontracted partner, Southern Maryland Cable, Sumter Utilities is facing the challenges of a high water table, unstable soil, existing underground utilities, Maryland winter weather, and as many have seen in 2021, material procurement. The supply chain issues and the intricacies of this project have given plenty of obstacles to overcome, but the team is scheduled to complete the project on time in May of 2022.
