At Dominion Energy, we are dedicated to finding the best solution for the long-term energy needs within the communities we serve. As we remain focused on reliability, we have identified an aging electric transmission line, which has been in operation for over five decades and have initiated a project to rebuild the line. This aging line which is known as the Calhoun County – St Matthew 46 kV is 10 miles in length and will be rebuilt exclusively on existing rights-of-way.

The engineering design and environmental permitting began in the first quarter of 2021 and will continue throughout the year. Line construction is expected to start in the first quarter of 2022 and is expected to be complete by the end of 2022. Letters will be sent out to impacted property owners along the route as DESC gets closer to construction.

Dominion Energy South Carolina will be replacing the existing 46 kilovolt (kV) wooden poles along this 10-mile corridor with self-supporting galvanized steel structures. The new line will be designed to meet all modern electric codes as well as provide additional reliability and resiliency to the areas along the route. The rebuilt lines will be constructed by contractors of Dominion Energy. At this time, DESC expects there to be no interruptions in power to its customers.

The project in Calhoun County near the intersection of Kennerly Road and Ringneck Trail. The line traverses in an easterly direction and crosses Highway 21 and I-26. The transmission line rebuild will conclude in the town of St Matthews and the existing substation.

While most of the line is away from heavily traveled areas, there will be an interstate crossing. DESC will be coordinating with SCDOT and law enforcement to schedule this interstate crossing work and ensure it is done in a safe and effective manner. Aside from the interstate crossing, there shouldn’t be any major interruptions to normal traffic patterns.
