2025 Integrated Resource Plan
The Tennessee Valley Authority (TVA) is profoundly grateful for the public’s participation in the development of its 2025 Integrated Resource Plan (IRP), a comprehensive plan that will shape TVA’s energy system through 2050. TVA also is preparing an Environmental Impact Statement (EIS) to evaluate the impacts associated with the IRP.
Public input is vital to the IRP process, and people across the region showed up in a big way. TVA shared the draft 2025 Integrated Resource Plan and accompanying draft Environmental Impact Statement on Sept. 23, 2024. That launched a public comment period that ended on Dec. 11, 2024.
During the public comment period, TVA hosted two virtual webinars and 10 in-person open houses throughout the Valley, with a total of 594 participants who asked a collective 376 questions about the IRP and EIS. TVA received more than 2,200 official comments regarding the draft IRP and EIS.
Today, TVA is reviewing and evaluating public input and conducting further analysis to appropriately incorporate feedback provided during the public comment period. The final document will incorporate changes made based on the evaluation of stakeholder and public comments, and all comments will be addressed in the final EIS.
The final IRP will include power supply mix ranges, recommendations for strategic portfolio direction through 2035 and information on factors that will influence portfolio direction from 2035 to 2050. If the TVA Board accepts the IRP recommendations, the IRP will serve as TVA’s compass for power generation decisions as well as for long-term operational and financial planning.

Engagement in the 2025 Integrated Resource Plan
Thank You for Your Involvement
Public participation in TVA’s integrated resource planning improved the process and will strengthen the final plan, which is expected to be released in spring 2025. Most recently, the public actively engaged during the 75-day public comment period, which ended on Dec. 11, 2024, by submitting official comments and offering input at IRP webinars and public open houses.
About the 2025 IRP Working Group
The IRP Working Group is a diverse group of stakeholders that meets regularly to provide comprehensive feedback on the IRP. The members represent the broad perspectives of those who live and work in the Valley. The IRP Working Group includes both customer and stakeholder representatives.
- Local Power Companies & Customer Associations (8)
- Associations / Special Interest Groups (3)
- Academia / Research (3)
- Government/Elected Officials (4)
- Energy and Environmental Non-Government Organizations (3)
- Community Stakeholders (3)
As a researcher at ORNL, the IRP process helps us evaluate the practical considerations for successful decarbonization and drives us to have a strong action plan toward a resilient, secure, clean grid for the Valley.

The Valley faces important decisions as we tackle challenges such as shifting environmental policies and conflicting political priorities to new and expensive generation technologies. The stakes are high, so we need to get this right.

2025 Integrated Resource Plan Process
Planning
TVA’s integrated resource planning is grounded in fundamental least-cost principles: low cost, risk informed, environmentally responsible, reliable and resilient, diverse and flexible.
Long-term planning entails considering future energy demand, evolving regulations, current power generation resources and new resource options, then determining what new power resources would work best to fill future capacity needs.
The IRP helps identify the optimal mix of resources for the region’s future energy system.

Engagement
Gathering diverse opinions from key stakeholders and the public strengthens the IRP and EIS process. In addition to the IRP Working Group, the Regional Energy Resource Council (RERC), a federal advisory committee that provides formal advice to the TVA Board of Directors, is engaged in the process.
The public has provided input during every phase of the IRP process – from the public scoping comment period early on through the recent public comment period related to the draft IRP and EIS. Public input is helping shape TVA’s energy system of the future.

Analysis
TVA and the IRP Working Group identified possible futures TVA could find itself operating in between now and 2050 and the alternative approaches to help meet electricity demand in these futures. They developed a list of power generation resource options for the IRP, including existing resources and emerging technologies.
TVA modeled the five strategies in the six scenarios. The modeling generated 30 unique potential resource “portfolios” – the power supply mix that results from assessing a particular strategy in a particular scenario. Additional analysis is being performed to evaluate evolving conditions and public input on the draft IRP.
