Risks

• Ability to implement business strategy, including meeting forecasted load growth, grid modernization, and carbon emission reduction goals, while balancing customer reliability and affordability.
• Uncertainty of costs and liabilities to comply with existing and future environmental requirements, including coal ash remediation and GHG emission regulations.
• Ability to timely recover eligible costs, including those for coal ash impoundment retirement, carbon emissions reductions, and significant weather events, through rate case proceedings.
• Costs of decommissioning nuclear facilities could exceed estimates and may not be fully recoverable.
• Impact of extraordinary external events, such as global pandemics, trade wars, or military conflicts, on supply chains and economic activity.
• Industrial, commercial, and residential decline in service territories due to economic downturns, storm damage, reduced customer usage from inflation, tariffs, or fuel costs, or lower than anticipated load growth (e.g., data centers).
• Federal and state efforts promoting energy efficiency, natural gas electrification, and distributed generation technologies could lead to reduced customers, excess generation, and stranded costs.
• Cybersecurity threats, data security breaches, operational events, information technology failures, or other catastrophic events could impact facilities and business.
• Fluctuations in commodity prices and interest rates, and the ability to timely recover such costs through the regulatory process.
• Construction and development risks associated with capital investment projects, including financing, regulatory approvals, budgets, schedules, and cost recovery.
• Failure to complete strategic transactions (e.g., Florida minority interest sale, Piedmont Tennessee business sale) could adversely affect financial condition, credit profile, and ability to execute business strategy, potentially requiring alternative funding sources.
• Legal proceedings, including class action lawsuits related to coal ash contamination and nuclear compensation, and ongoing litigation regarding interconnection agreements, could result in significant liabilities.

Future Outlook

Duke Energy anticipates continued accelerating investment opportunities and customer growth across its service territories. The company expects to efficiently fund its expanded capital plan through strategic transactions, including the Duke Energy Florida minority interest sale and the Piedmont Tennessee business sale, which will displace planned long-term debt and common equity issuances through 2029. Regulatory efforts will continue to focus on securing critical investments for reliable customer service and timely cost recovery. New advanced natural gas plants and planned combustion turbines are expected to provide critical generation for modernizing energy infrastructure. The proposed combination of Duke Energy Carolinas and Duke Energy Progress is targeted for January 1, 2027, aiming for substantial cost savings. The 2025 Carolinas Resource Plan outlines development and procurement activities for diverse generation assets to meet growing energy demands reliably and cost-effectively.

Industry Context

Duke Energy's strong financial performance and strategic initiatives align with broader industry trends focusing on grid modernization, clean energy transition, and managing the impacts of climate change and extreme weather events. The company's significant capital investments in new generation, transmission, and distribution infrastructure reflect the ongoing need for reliability and resilience in the face of growing energy demand and evolving regulatory landscapes. The strategic asset sales and minority interest investment demonstrate a proactive approach to capital allocation and funding growth, a common theme among large utilities navigating the energy transition. Regulatory approvals for rate increases and cost recovery mechanisms are crucial for utilities to fund these capital-intensive projects and maintain financial health, especially with increasing environmental compliance costs and storm-related expenses. The focus on hydrogen-capable natural gas plants and nuclear license renewals indicates a diversified approach to clean energy, balancing intermittent renewables with reliable baseload generation.
