• "TVA anticipates a need to increase debt in the coming years as it continues to invest in power system assets, which may result in positive net cash flows provided by financing activities in future periods."
• "TVA believes that the actions taken by the TVA Board since April 1, 2025, are authorized under its bylaws or otherwise."

Industry Context

The utility industry is experiencing increasing electricity demand, necessitating substantial capital investments in new generation and infrastructure. TVA's strategic shift towards lower-carbon emitting sources like natural gas, renewables, and small modular reactors (SMRs), alongside the retirement of aging coal-fired plants, aligns with broader industry trends for decarbonization. The dynamic regulatory environment, marked by new EPA rules and ongoing legal challenges to infrastructure projects, highlights the increasing scrutiny and compliance costs faced by utilities. Industry-wide challenges such as supply chain disruptions, inflation, and labor availability are impacting project timelines and costs. TVA's focus on energy efficiency and demand response programs reflects a common industry approach to manage load growth and optimize resource utilization. The development of SMRs, supported by government grants, represents an emerging technology in the nuclear sector, indicating a long-term commitment to diverse energy portfolios.

Comparison to Industry Standards

• TVA's 53% reduction in mass carbon emissions and 49% reduction in carbon emission rate from 2005 levels (as of CY 2024) demonstrates significant progress in decarbonization, comparable to or exceeding targets set by many U.S. utilities. For example, Xcel Energy aims for an 80% carbon reduction by 2030 from 2005 levels, and Duke Energy targets a 50% reduction by 2030 from 2005 levels.
• The 5.25% wholesale base rate increase effective October 1, 2024, reflects rising costs and capacity needs, a common trend across the utility sector as companies invest in grid modernization and new generation. Utilities like Pacific Gas and Electric (PG&E) and Commonwealth Edison (ComEd) have also sought and received rate increases to fund infrastructure upgrades and clean energy transitions.
• The investment of $3.44 billion in construction expenditures for the nine months ended June 30, 2025, primarily for natural gas plant builds and nuclear fleet upgrades, aligns with industry trends of significant capital expenditure in generation and transmission infrastructure to meet growing demand and transition the energy mix. Comparable projects include NextEra Energy's substantial investments in renewable energy and battery storage, and Southern Company's ongoing nuclear plant construction (e.g., Vogtle).
• The all-time record peak power demand of 35,430 MW on January 22, 2025, indicates robust demand growth, consistent with broader trends in the U.S. Southeast driven by economic development and data center expansion. This is comparable to peak demands seen in other large regional grids, such as ERCOT in Texas or PJM in the Mid-Atlantic, which also experience significant demand spikes due to weather and industrial growth.
• The delay in the 2025 Integrated Resource Plan (IRP) publication is a concern, as IRPs are critical for long-term planning in the utility sector. Delays can impact strategic decision-making and regulatory approvals, as seen with other utilities facing complex planning challenges.
