Duke Energy is a utility company that generates, transmits, and distributes electricity and also provides natural gas services to residential, commercial, and industrial customers. It operates a regulated energy business model where electricity is produced from a mix of sources such as nuclear, natural gas, coal, hydro, solar, and other renewables, and then delivered through regional power grids. The company serves millions of customers across multiple U.S. states, primarily in the Southeast and Midwest, where it operates electric utility subsidiaries and natural gas distribution networks. Its infrastructure includes power plants, transmission lines, and local distribution systems that support everyday electricity and gas delivery to households and businesses. Duke Energy also invests in expanding and modernizing its energy systems, including grid upgrades, renewable energy integration, and new generation capacity to meet rising demand. This includes long-term capital projects aimed at improving reliability, supporting electrification trends, and addressing growing electricity needs from sectors such as data centers. In addition to core utility operations, the company engages in regulated natural gas infrastructure projects, pipeline investments, and renewable energy development. It works within state-regulated frameworks where pricing, expansion, and infrastructure investment decisions are typically overseen by public utility commissions.
