Mitsubishi Power announced Monday that it will build a gas turbine manufacturing plant that eventually could employ about 500 workers at the Pooler mega-site near Savannah.
Mitsubishi Power will be the first tenant in nearly a decade at the mega-site, where officials have unsuccessfully courted one company after another.
Auto company Daimler-Chrysler was slated to build an auto plant there but it never happened.
The plant is a $300 million investment for Mitsubishi Power and represents a significant expansion of its North American operations.
Governor Sonny Perdue said he believes it's better the megasite has more than one tenant.
"I think, frankly, that it'll enjoy the benefits of a cluster effect. And if you give me 500 jobs on a little over 100 acres, we'll do that every day," Perdue said.
The plant could be open by this time next year. It will make turbines for electrical plants, which will be distributed to part suppliers in the region.
