Revenue Model & Pricing
Duke Energy runs a cost-of-service utility model. In its core territories it is the franchised provider, so it does not compete for most retail customers. State commissions and FERC set rates that let Duke recover operating and fuel costs and earn an authorized return on its rate base, the depreciated value of plants, wires and pipes. Earnings grow when Duke invests capital that regulators approve for recovery. About 90% of revenue comes from regulated electric service and roughly 9% from regulated gas distribution.
Core Revenue Streams

Growth Strategy
Growth comes from regulated capital spending. In February 2026 Duke raised its five-year plan to $103 billion for 2026-2030, with most of it going to grid infrastructure and new generation, including more than 5 GW of natural gas plants under construction, solar and battery storage, and nuclear license renewals. Duke is also recycling capital: it sold Piedmont's Tennessee gas business to Spire for $2.48 billion (closed March 31, 2026) and is selling a 19.7% stake in Duke Energy Florida to Brookfield for $6 billion, with the first $2.8 billion tranche for 9.2% already closed.

How is Duke Energy powering the large industrial and AI data center expansion in the Southeast?
The Southeast US is experiencing rapid industrial in-migration (semiconductor manufacturing, EV battery gigafactories, and hyperscale AI data centers). Duke Energy is expanding multi-gigawatt transmission and generation capacity to power tens of billions in new economic development projects.
What role does solar energy and battery storage play in Duke Energy's fleet?
Duke Energy is one of the top utility solar operators in the nation, with thousands of megawatts of solar and battery storage in service and plans to add over 15,000 megawatts of renewable energy and energy storage across North Carolina, South Carolina, and Florida by 2035.
What is Duke Energy's coal retirement schedule?
Duke Energy is systematically retiring its remaining coal-fired power plants across North Carolina, Indiana, and Kentucky by 2035, replacing them with cleaner natural gas combined-cycle stations, solar, battery storage, and advanced nuclear power.
How does Duke Energy manage storm restoration and grid resilience?
Duke Energy operates specialized grid hardening programs: self-healing smart grid automation that automatically isolates line faults and restores power to customers in seconds, undergrounding vulnerable power lines, and deploying thousands of lineworkers during severe hurricane events.
