Overview
Duke Energy Corporation is a Charlotte-based American utility holding company whose principal businesses are regulated electricity generation, transmission, distribution and retail supply, together with natural-gas distribution. Its service operations extend across parts of the Carolinas, Florida, Indiana, Ohio and Kentucky, and the company serves more than seven million customers. Duke operates a diversified generation fleet that includes nuclear, coal, natural gas, hydroelectric and other facilities, while investing in grid modernization, renewable energy and lower-carbon generation. The company traces its origins to hydroelectric development on the Catawba River in the Carolinas. Walker Gill Wylie and his brother helped establish the Catawba Power Company in 1900, and James B. Duke later supplied capital for a broader Southern Power system. A sequence of consolidations produced Duke Power in 1924. The business expanded from generation into retail electricity, utility infrastructure and, for a period, transit operations in the Carolinas. Duke Power became Duke Energy in 1997 after merging with PanEnergy, a natural-gas company. The 2006 acquisition of Cinergy expanded the company into the Midwest and added substantial fossil-fuel generation and utility operations. Duke subsequently separated its gas-pipeline business into Spectra Energy in 2007, merged with Progress Energy in 2012, and acquired Piedmont Natural Gas in 2016. These transactions reshaped Duke into one of the largest regulated utilities in the United States. Duke's business has also been defined by environmental and regulatory controversies. Its coal-plant permitting practices were challenged under the Clean Air Act, leading to the 2007 Supreme Court decision in Environmental Defense v. Duke Energy. Coal ash management, emissions, proposed coal construction and nuclear-project planning have remained recurring public issues. The company has advocated carbon regulation and cleaner generation while continuing to operate a substantial legacy fossil-fuel and nuclear fleet. In 2023, Duke sold its unregulated utility-scale renewable-generation business to Brookfield Renewable Partners, sharpening its focus on regulated utility operations. The company continues to plan investments in grid capacity, reliability, customer growth and decarbonization. Its corporate identity is therefore tied both to large-scale regulated infrastructure and to an established southeastern utility's difficult transition toward a lower-emission energy system.
History
Duke Energy developed from early twentieth-century hydroelectric projects on the Catawba River. Walker Gill Wylie and his brother financed the Catawba Power Company in 1900, and James B. Duke and James Blaney later invested in the Southern Power Company, founded in 1905. In 1917, Blaney established the Wateree Power Company as a holding structure for several related utilities. That organization was renamed Duke Power in 1924, consolidating Southern Power, Catawba Power, Great Falls Power and Western Carolina Power. A legally separate retail affiliate, Southern Public Utilities, marketed Duke-generated electricity and also operated transit systems before those operations were converted to buses and eventually sold. Duke expanded its Carolina utility footprint during the twentieth century. It bought Nantahala Power & Light from Alcoa in 1988, bringing southwestern North Carolina operations and a connection to the Tennessee Valley Authority system into the group. In 1990 it disposed of its remaining transit businesses. The 1997 merger with PanEnergy created Duke Energy and broadened the company from a primarily electric utility into a combined electric and natural-gas enterprise. The 2005 agreement to acquire Cinergy was completed in 2006 and significantly enlarged Duke's Midwest presence through utilities in Ohio, Indiana and Kentucky. Duke also acquired Union Gas in Ontario in 2006, but spun off its gas business in 2007 as Spectra Energy. Shareholders received Spectra shares, and Duke thereafter focused more strongly on electric utilities. In 2012 Duke merged with Progress Energy, adding major Florida and Carolinas operations. Lynn Good became chief executive in 2013 after Jim Rogers retired. Duke purchased Piedmont Natural Gas in 2016, while later selling its remaining Latin American generation interests. Strategic and regulatory debates have accompanied this growth. Duke faced labor conflict at its Brookside coal mine in Kentucky in 1973, environmental litigation over coal-plant modifications, criticism of emissions and coal-ash practices, and opposition to new fossil-fuel and biomass projects. The company proposed a nuclear station at Cherokee County, South Carolina, but sought cancellation in 2017 after Westinghouse's bankruptcy and changed market conditions; by 2018 new nuclear generation was absent from its long-range plans. Duke has nevertheless maintained nuclear power as an important part of its Carolinas generation portfolio and has supported carbon-pricing or cap-and-trade approaches. In the twenty-first century, Duke has emphasized reliability, digital infrastructure, efficiency and cleaner generation. It participated in Envision Charlotte, a 2011 smart-city initiative intended to reduce energy consumption in the city's urban core. In 2023 it sold its unregulated utility-scale renewable portfolio to Brookfield Renewable Partners, sharpening its focus on regulated utility operations. The company remains a major American infrastructure operator, balancing customer and reliability requirements with decarbonization, regulatory oversight and the retirement or replacement of older generation assets.

Products and positioning
A large regulated utility pursuing grid modernization and an energy-transition strategy while operating a diversified legacy generation fleet.
Utility service
Regulated electricity service
Duke's core offering is regulated electric service for residential, commercial and industrial customers. The service combines generation procurement or ownership with transmission, distribution, metering, billing and reliability obligations. Operations are conducted through state-regulated utility subsidiaries across the Carolinas, Florida and parts of the Midwest.
Utility service
Natural-gas distribution
Duke distributes natural gas through utility businesses including Piedmont Natural Gas and related state operations. The offering includes pipeline distribution, customer connections and regulated gas service, although Duke's corporate portfolio has changed substantially since the former broader gas business was spun off as Spectra Energy.
Energy generation
Electric generation portfolio
The generation fleet includes nuclear, coal, natural-gas, hydroelectric and other facilities. Duke uses baseload, intermediate and peaking resources to support regulated customer demand, while gradually changing the portfolio through plant retirements, grid investment and lower-carbon development.
Renewable energy
Renewable energy
Duke has developed and operated renewable-generation assets and customer programs. Its unregulated utility-scale renewable-generation business was sold to Brookfield Renewable Partners in 2023, while renewable and cleaner-energy activities remain part of the company's broader transition strategy.

1999
Coal-plant Clean Air Act enforcement dispute
The Environmental Protection Agency challenged Duke's modifications to older coal plants, arguing that the work increased operating hours and emissions without the required permits. The Supreme Court ruled against Duke's interpretation in 2007.
1973
Brookside coal-mine labor conflict
Workers at Duke-owned Brookside mine in Harlan County, Kentucky, conducted a thirteen-month dispute over medical benefits and recognition of the United Mine Workers of America.
