Mitsubishi Power Plans $490M Georgia Gas Turbine Plant Expansion

Mitsubishi Power Americas will invest $490 million in a Georgia gas turbine plant expansion at its Savannah Machinery Works near Pooler, adding 450,000 square feet to make gas-turbine parts, and plans to create more than 220 jobs, Gov. Brian Kemp's office said on Oct. 23.

It is the largest investment to date by Mitsubishi Power Americas, according to Trip Tollison, president and CEO of the Savannah Economic Development Authority. The plant sits at 1000 Pine Meadow Drive. The new space will host manufacturing, operations, heavy-machinery and technician roles. WTOC reports that Mitsubishi hopes to have the expansion running by early 2029; the governor's release gives no date.

Bill Newsom, president and CEO of Mitsubishi Power Americas, tied the project to electricity demand. "Meeting the growing demand for power will require investment in facilities, in our supply chain, and in our workforce," he said in the governor's release. Neither that release nor the company's remarks mention data centers by name. The Atlanta Journal-Constitution frames the expansion against AI data center load and reports that it is expected to double the plant's production capacity; the governor's headline speaks of doubling the company's footprint, which is floor space rather than output.

What the Expansion Means for Gas Turbine Supply

Gas plants built for large new loads need turbines, and a turbine is only as available as the factories that machine its parts. A 450,000-square-foot addition in the United States adds domestic parts capacity, but on the early-2029 target the added space would not affect deliveries before then. Voltgrid News reported earlier on Serverfarm's Arkansas campus starting on gas turbines. The announcement gave no output in MW and no turbines-per-year figure for the expansion, so its effect on supply cannot yet be measured.

Georgia Power welcomed the news. In a statement carried by WTOC, the utility said the next generation of turbines and equipment used in its power plants is being produced in Georgia. The AJC reports that the Savannah plant built a gas turbine installed in 2025 at Georgia Power's Plant Yates.

Site and background

Mitsubishi Power is the power-solutions brand of Mitsubishi Heavy Industries (MHI), based in Tokyo. Its range covers gas, steam and aero-derivative turbines, geothermal systems and environmental controls, and it also offers software for autonomous operation of power plants.

The Savannah plant opened in 2010 after a September 2009 groundbreaking, according to the Savannah Business Journal, and WTOC describes it as the first full gas-turbine plant outside Japan. Georgia's economic development commissioner, Pat Wilson, said the state's ports, rail, highways and airports were a reason for the company's continued investment there.

How Turbine Factories Limit New Gas Power

A gas turbine burns fuel to spin a shaft that drives a generator, and each machine is built from precisely machined parts. A utility can have a site, a permit and a gas line and still wait on the factory that makes those parts.

That is why factory floor space matters to anyone planning firm power for new load. Until the company states what the Pooler addition will produce each year, buyers can count it only as future parts capacity, not as turbines in the queue.

What is not confirmed yet

The announcement gives no turbine output or annual production target, so the AJC's "double capacity" description is that outlet's reading rather than a company figure. No groundbreaking date has been set; Tollison said only that the authority looks forward to a future ceremony. The early-2029 start is a target reported by WTOC, and the $490 million is the company's investment figure for this Georgia project alone.
