The next project in Mississippi Power’s grid modernization effort began in Sumrall this morning.

As was the case in Purvis last year, crews from across the company, with assistance from contractors, will convert the substation and the feeder lines into Sumrall from 4kV to 12kV.

“Our experience with the Purvis conversion really prepared us for the opportunity Sumrall presents this year,” Engineering Supervisor Matt Ball said. “The team that led the Purvis project got us off to a great start as we work towards converting all of the 4kV distribution substations.”

Transmission and Substation crews have already installed a new transformer in the Hwy. 42 sub. Once the load of the town is converted to the new sub, the existing sub’s configuration will be also be upgraded with a 12kV transformer.

“Having this additional source, one inside of town and the other outside will improve operational flexibility and reliability for our Sumrall customers,” Ball said.

And with the COVID-19 crisis unfolding across the state as this project begins, Mississippi Power crews and contractors are taking precautions.

“We’re encouraging our contractors to practice social distancing to avoid close contact, just as we have with our own employees to reduce risk,” Ball said.
