Protestors are set to gather in Charlotte as Duke Energy makes its case for another rate hike.
The protest, organized by Greenpeace, is to fight a proposed 5 percent hike and the pollution the group says comes from Duke's plants.
Eyewitness News heard from both the protestors and Duke Energy on Tuesday night, and found out how much more bills could go up and why Duke is proposing the hike.
Protestors made their signs Tuesday night in hopes of making a statement on Wednesday.
"No rate hikes for Duke Energy," said Monica Embrey.
Embrey, a member of Greenpeace, and said she and 100 others plan to protest Duke Energy's proposed rate hike Wednesday night at a public hearing.
"We are sick and tired of paying more for dirty energy sources like coal, nuclear and natural gas," she said.
Duke is proposing a 5 percent increase across the board for residential and commercial rates. While the company won't say how it will divide the rate hike, a 5 percent increase for an average home electric bill would cost about $6 more per month.
Duke said it needs the increase to better serve customers.
"This is about the power behind the light switch," said Duke spokeswoman Lisa Parrish.
She said 90 percent of the increase will pay for capital investments that will benefit the customers.
"We're modernizing our facilities, we're retiring older coal units that were built in the 1940s and replacing them with new, efficient, environmentally-friendly cleaner coal and natural gas plants," said Parrish.
But protestors said they want cleaner, safer, renewable energy sources such as wind and solar, and they plan to make that clear on Wednesday.
"We're there to listen, and we value that opportunity to listen to our customers," said Parrish.
Embrey said a study this year shows that Duke could cut power bills in half if it switched to those renewable energy sources.
The meeting is set to start at 6 p.m. on Wednesday.
