OVERVIEW OF TVA DRAFT 2025 IRP + EIS
INITIAL RESULTS The draft IRP analyzes potential ways the resource portfolio might evolve between now and 2035 and from 2035 to 2050. Insights gained from evaluating the entire planning horizon will inform portfolio direction between now and 2035. Looking across all portfolios through 2035, the draft IRP results suggest:
1 to 4 GW EE and DR additions
4 to 19 GW Natural gas,
3 to 20 GW Solar nameplate additions
Between now and 2035 9 to 26 GW Incremental firm capacity needs
hydrogen, and CCS additions
In all scenarios, TVA will continue to provide AFFORDABLE, RELIABLE, RESILIENT, and increasingly CLEANER energy for the region for decades to come.
Up to 4 GW Wind nameplate additions
Up to 1 GW Nuclear additions
Up to 6 GW Storage nameplate additions
Projected 75 to 90 % Reductions in CO 2 intensity from 2005 baseline
Power supply mix ranges, summarized in gigawatts (GW), vary based on energy demand, market conditions, policy and regulations, and technology advancements.
DRAFT IRP KEY THEMES ARE:
Gas expansion serves broad system needs, with the potential for emerging
Solar expansion plays an increasingly substantial role, providing economic, carbon-free energy.
Firm, dispatchable technologies are needed to ensure system reliability throughout the year.
New capacity is needed in all scenarios to replace retiring and expiring capacity, support economic growth, and enable further electrification of the economy.
carbon capture and hydrogen options to enable deeper decarbonization.
Energy efficiency deployment reduces energy needs, particularly between now and 2035, and demand response programs grow with the system and the use of smart technologies.
Storage expansion accelerates, driven by evolving battery technologies and the potential for additional pumped storage.
Wind additions have the potential to add more diversity and carbon-free energy to the resource mix.
New nuclear technologies, with continued advancements, can also support load growth and deeper decarbonization.
The draft results also indicate that TVA would see continued reductions in carbon intensity beyond 2035.
