CUMMING — There was an issue with delivery, but two massive generators for the Cumming Utilities Department were installed earlier this week.

The larger of the two generators, which provides 25,000 kilowatts of power, was placed at Cumming’s raw water intake station on Magnolia Avenue at Lake Lanier. The smaller, topping out at 15,000 kilowatts, went to the Dobbs Creek water facility.

“The generators will be on site and ready to provide power to the raw water intake facility,” said Jon Heard, the city’s director of utilities. “The generator at the water production facility will provide power to the … facility in the event of a catastrophic power failure.”

The generators were paid for using 1-cent sales revenue. Per an agreement with the city, Forsyth County contributed $1 million toward the intake generator.

According to Heard, the total cost of both generators was about $2.5 million.

The delivery of the larger generator was slowed Tuesday when the truck carrying it got stuck at Magnolia Avenue and Pilgrim Mill Road.

“We had a little bit of problem with the physical delivery on the roads,” said Terry Morrissey, director of business development for Gainesville-based Caldwell Electrical Contractors Inc.

“It being a 90-ton unit, it’s roughly the size of a railroad car rolling down the streets of Forsyth County. We had a little difficulty getting past one bump in the road, literally, but we were able to bring in some people to help us get through it.”

Morrissey said that the delivery was the only misstep.

“Once we got in down to the lake, installation went pretty flawlessly,” he said. “We had everything ready to go at that point, and lifted 90-tons straight into the air and dropped it right where it was supposed to go, within about 3/8 of an inch or quarter inch maximum. It was pretty close to perfect.”

Heard said some work remains, most notably connecting the generators.

“There are some other minor components to the project, like installing grass and sidewalks,” he said. “Currently, the major portion of the project that remains is connecting the generators to the switch gear in the pump control buildings.”
