About Duke Energy
Duke Energy is one of the largest electric power holding companies in the United States, serving over 8 million customers across six states. With roots dating back over a century, Duke has become a household name in many regions, providing a mix of electricity generation from nuclear, coal, natural gas, hydroelectric, solar, and wind sources. The company has a strong focus on sustainability, aiming to reach net-zero carbon emissions by 2050, and it invests heavily in modernizing the grid to improve reliability and integrate more renewable energy.
Duke Energy Coverage Areas
Duke Energy’s regulated utility operations cover large parts of North Carolina, South Carolina, Florida, Indiana, Ohio, and Kentucky. It’s important to know that in some states like Ohio, you can choose a retail electric providers (REPs) in a competitive market, but Duke operates primarily in regulated markets, meaning you purchase electricity directly from Duke rather than choosing from competing suppliers.
- North Carolina and South Carolina: Duke Energy Carolinas and Duke Energy Progress serve most of these two states, making them the dominant electric utility provider. They supply power to both large metro areas like Charlotte, Raleigh, Durham, and Greenville as well as rural communities.
- Florida: Through Duke Energy Florida, the company provides electric service across central and northern Florida, including areas like St. Petersburg, Clearwater, and parts of Orlando and the Gulf Coast.
- Indiana: Duke Energy Indiana supplies electricity to central and southern parts of the state, including cities like Bloomington, Terre Haute, and Plainfield.
- Ohio: Duke Energy Ohio serves both electricity and natural gas customers, mostly in the Cincinnati metro area and surrounding southwest Ohio counties. Importantly, electricity and natural gas supply are both deregulated here, giving customers the option to choose a REP or gas supplier for the supply portion.
- Kentucky: Duke Energy Kentucky covers electric and natural gas customers mainly in northern Kentucky, across counties like Boone, Kenton, and Campbell, right across the river from Cincinnati. Similar to Ohio, customers here can shop for alternative suppliers.
Types of Energy Duke Supplies
Duke Energy supplies both electricity and natural gas to customers, but availability depends on the region.
- In North Carolina, South Carolina, Florida, and Indiana, Duke primarily provides electricity services.
- In parts of Ohio and Kentucky, Duke Energy supplies both electricity and natural gas, they manage gas distribution and also deliver supply, though customers can choose alternative natural gas suppliers in deregulated markets if they want to shop for rates.
For electricity, Duke generates power using a diverse mix: natural gas, nuclear, coal, hydroelectric, solar, and wind. For natural gas, they focus on safe, reliable delivery through local pipelines to homes and businesses, offering flexible billing and energy-saving options for gas users.
Their growing renewable portfolio means you may have the option to enroll in programs that support clean energy, even if your specific energy plan is regulated.
Choosing a Retail Electric Provider (REP)
Choosing a retail electric provider (REP) over Duke Energy can offer more flexibility, customization, and sometimes even cost savings, depending on your household’s needs. While Duke Energy provides standard regulated rates and reliable service, REPs in deregulated markets (like Ohio or Kentucky) give you the power to shop around for plans that fit your lifestyle. You might find fixed-rate plans that protect you from seasonal price swings, variable-rate plans if you prefer market-driven rates, or even time-of-use or free nights/weekends plans if your energy use is concentrated at certain hours. Many REPs also offer 100% renewable energy plans, letting you align your electricity use with your sustainability goals in ways Duke’s standard mix may not.
Another advantage of choosing a REP is access to special perks and programs. Some providers bundle in smart home devices, energy-saving tools, or loyalty rewards that Duke’s basic supply service doesn’t include. If you’re someone who likes to comparison shop, lock in a long-term price, or tap into promotional offers, going with a REP can put more control and potential savings in your hands, as long as you read the fine print and understand the contract terms.
If you’re in a deregulated market like parts of Ohio or Kentucky served by Duke, you can shop for a REP. Here’s some things to consider:
- Price per kWh: Compare fixed-rate, variable, or time-of-use plans to see what fits your household’s needs.
- Renewable energy options: Some REPs offer 100% green energy plans if you want to lower your carbon footprint.
- Contract terms: Watch for early termination fees, contract lengths, and any fine print.
- Reputation: Check online reviews, customer service ratings, and reliability.
- Special perks: Some REPs offer smart thermostat deals, free weekends, or app-based usage tracking.
