What Services Does Duke Energy Provide?

Duke Energy is one of the largest electric power holding companies in the United States. They are headquartered in Charlotte, North Carolina and provide electricity and natural gas service to approximately 7.4 million retail customers in Florida, North Carolina, South Carolina, Ohio, Kentucky and Indiana. Duke Energy has roots dating back to the 1800s and was known as Duke Power until 2006 when it acquired Cinergy to become Duke Energy. The company has approximately 27,000 employees focused on providing affordable, reliable energy to customers and communities while also working to transition to more sustainable energy sources.

Electricity Generation

Duke Energy operates power plants across multiple states to generate electricity for its customers. The company has a diverse mix of generation sources including coal, natural gas, nuclear, hydroelectric, solar, and wind. This allows Duke Energy to reliably meet electricity demand while balancing costs and environmental impacts.

Coal power plants make up the largest portion of Duke Energy’s generation capacity. The company operates coal plants in the Carolinas, Indiana, Kentucky, and Ohio. Coal provides a low-cost, stable source of electricity, though it produces higher emissions than other fuel sources. Duke Energy is adding emission control systems to reduce air pollutants at its coal plants.

Natural gas is an increasingly important part of Duke Energy’s generation mix. The company operates combined-cycle natural gas plants that utilize waste heat to achieve high efficiency. Simple cycle gas turbines can also ramp up quickly to meet periods of peak demand. New gas plants are helping to replace retiring coal plants in a cost-effective way while lowering emissions.

Nuclear energy provides over 10% of the electricity generated by Duke Energy. The company owns and operates nuclear plants in the Carolinas and Florida. Nuclear offers reliable baseload electricity with zero air emissions. Duke Energy’s nuclear fleet has delivered strong performance for decades.

Hydroelectricity, solar, and wind make up a small but growing share of Duke Energy’s renewable generation. The company owns and operates hydroelectric dams and has installed over 3,000 megawatts of solar capacity. Duke Energy is also contracting for wind power and developing more utility-scale solar sites across its service regions.

Electricity Transmission

Duke Energy operates and maintains thousands of miles of electricity transmission lines and towers across its service territories. These high-voltage transmission lines, ranging from 115kV to 765kV, efficiently move large amounts of electricity from power generation plants to substations near demand centers.

Investments in transmission infrastructure ensure electricity can be delivered reliably to homes and businesses. Upgrades to the transmission system also enable greater integration of renewable energy like solar and wind onto the power grid. Smart grid technologies help monitor and control the flow of electricity across the transmission network.

Duke Energy coordinates transmission planning and operations across multiple states. By sharing electricity resources between operating companies and optimizing the entire transmission system, Duke Energy can keep the lights on for customers during even the highest demand periods.

Electricity Distribution

Duke Energy operates one of the largest electricity distribution systems in the United States, delivering power to customers in six states. The company maintains approximately 129,000 miles of distribution lines and over 1,000 electricity substations across its service territories.

Distribution lines carry lower voltage electricity from high voltage transmission lines and substations to homes and businesses. Duke Energy continually monitors and upgrades its distribution system to improve reliability. It has invested significantly in smart grid technology, including automated meters, outage detection systems, and advanced transformers and switches. These upgrades provide greater visibility into outages and allow for more precise, faster service restoration.

Smart grid enhancements also enable advanced analytics to optimize power flows and use predictive maintenance to reduce equipment failures. Together with ongoing tree trimming and inspections, Duke Energy’s distribution investments help reduce the frequency and duration of power outages while meeting growing energy demands across its service area.
