Folks in Warren County have seen those huge cranes on 522 for months, but what's really going on in there?

We got an exclusive tour and leaders said the plant will help provide power for more that 400,000 homes in Virginia.

With 600 employees, about 17 cranes and a year of construction under their belt, the eco-friendly Dominion Power Plant in Warren County looked like it was being built fast, but it's only 15 percent complete.

"We're working on a lot of things at once, but probably the main thing we're working on right now is getting the combustion turbans completed. Those are essentially gigantic jet engines," said Spokesperson Dan Genest.

The gigantic engines are one thing that will make the power plant safe for the environment. "We're getting another 570 megawatts of electricity from steam which have no emissions what so ever," said Genest.

The big towers that are being built are steam recovery systems. So, what happens is, the combustion turban produces electricity, but it also produces tremendous amounts of heat. The heat turns to steam and then another building turns that into electricity. "It would be extremely hot, you wouldn't want to be in there," Genest added.

They're not just building a power plant, they want to build a relationship with the community. "We are doing some projects down on the river that we're not quite ready to announce yet, but we're doing some big things down there. We're very active in the United Way," Genest said

Leaders said since the weather is getting better, they have increased the hours of construction, so people will be out working for ten hours a day and seven days a week. They still plan on having the plant ready to go by the end of 2014.
