As the housing market rebounds, manufacturers start to expand and consumers continue to plug in more devices, the need for electricity will grow, perhaps as much as 30 percent by 2030, according to the Energy Information Administration.
It’s likely that new plants will make electricity produced from natural gas as ample supplies of the fuel at cheap prices have made it popular across all industries.
In the past five years, Southern has cut the amount of electricity it produces from coal from 70 percent down to 35 percent. The amount it produces from natural gas has risen from 16 percent to 40-45 percent.
Natural gas is known for wild price swings, however, and predicting how much the fuel will cost in the decades to come is difficult. Keogh at NARUC, the regulator’s group, showed two charts with conflicting price projections.
“I can tell you with a pretty decent amount of confidence that somebody out there thinks the price of gas in 2030 is going to be between 2 bucks and 9 bucks,” he said, as the crowd laughed. “So let’s not say we have a really perfect vision. This is decision-making under conditions of uncertainty.”

The push to add renewable energy, particularly wind and solar, adds another complex layer to long-term decisions about where utilities will get their electricity. Once known for high manufacturing and installation costs, solar and wind energy has become more competitive with traditional fuels. But Southern and its utilities have resisted adding renewable energy in large amounts.
Executives routinely tout the region’s lower electricity rates and the lack of natural abundance of renewable resources as two main reasons why.
Georgia Power recently signed a contract to buy wind power from Oklahoma. The utility also is expanding a solar program.
“We’ve been working hard, but a lot of it has been outside of the state,” said Dan Fossitt, president of Atlanta-based Inman Solar, which recently broke ground on a solar project in Polk County. Inman Solar is installing solar projects in Polk and Marion counties as part of Georgia Power’s so-called “advanced solar initiative.”
The projects are helping Inman Solar and other Georgia-based solar manufacturers and installers do more work closer to home, keeping the economic benefits local.
“The fact that most of our projects right now are in state and close to home is certainly good,” Fossitt said.

Environmental rules requiring utilities to cut mercury and other air toxins from its coal-burning plants will lead Georgia Power to close 15 coal and oil units statewide.
Eventually after the closings and changes, Georgia Power will operate five coal plants in the state, said Ron Shipman, Georgia Power’s vice president of environmental affairs.
“The more certain we are about which regulations are coming down the pike, the more we can make, more concretely, decisions on what we’re going to do with these facilities,” he said.
Next up will be rules requiring utilities to cut carbon emissions from coal-burning plants, Shipman acknowledged.
President Barack Obama has directed the federal government to work with the states on developing these rules, said Bob Perciasepe, EPA deputy administrator.
“This is a key ingredient on how we as a country are going to deal with this,” he said.
