The latest announcement from X-energy Reactor Company and TLN is only a letter of intent, but the signal matters. The companies plan to evaluate at least three four-unit Xe-100 80 MWe high-temperature gas-cooled reactors in Pennsylvania and across PJM. The plan would extend TLN’s nuclear story beyond its Susquehanna conventional reactor into net new clean, firm capacity. In a market with high growth potential, as seen in our Long-Term Load Forecast – Pushing Peaks, it’s enough to keep small modular reactors (SMRs) in the conversation.
Enverus Intelligence® Research’s (EIR) recent Gone Fission – Nuclear PPA Comp Sheet shows why investors care. We estimate nuclear power purchase agreements signed by CEG, TLN and VST carried an average premium of over $30/MWh over zonal forwards at signing. In AMZN’s case, the premium rose more than 70% from its TLN Susquehanna deal (March 2024) to its VST Comanche Peak agreement (September 2025), signaling demand for nuclear offtake remains strong.
That said, our IPP NAV Compass makes a case for discipline. Advanced reactors still face permitting, siting, cost and supply chain hurdles, evidenced by Ontario Power Generation’s proposed Darlington BWRX-300, scheduled for startup by decade’s end. The company received a first-of-its-kind construction license for a grid-scale SMR in the G7 last April and the four units are estimated to cost C$20.9 billion in 2024 dollars. OPG last December sought regulatory approval to charge almost C$207/MWh beginning in January, roughly double the 2026 rate, with about a quarter attributed to the development of SMRs. TLN’s move shows long-duration nuclear contracts are becoming a strategic bridge between today’s cash-flow story and tomorrow’s growth options.
This blog offers just a glimpse of the powerful analysis Energy Transition Research delivers on the trending themes. Don’t miss the full picture.
Research Highlights:
- Long-Term Load Forecast | Pushing Peaks – We forecast long-term load growth across the L48.
- Gone Fission | Nuclear PPA Comp Sheet – We benchmark recent IPP nuclear PPAs and show how premium-priced offtake agreements lifted plant values across CEG, TLN and VST.
- IPP NAV Compass | Underappreciated PPA Upside – We connect nuclear contracting momentum to IPP valuations and show how long-duration PPAs support downside protection while preserving upside.
DID YOU KNOW?
Some advanced SMR and microreactor designs, particularly Generation IV liquid-metal-cooled concepts, aim to operate for 5-10 years between refueling, with some early-stage models targeting significantly longer core lifetimes.
Key Takeaways
Why does the X-energy and Talen announcement matter if it is only a letter of intent?
It signals serious interest in adding new nuclear capacity. Even without a final commitment, it keeps small modular reactors relevant as power demand grows and firm, clean supply becomes more valuable.
What does recent nuclear PPA pricing tell us about market demand?
Demand is strong and getting stronger. Nuclear PPAs are signing at large premiums over market prices, with some deals showing sharp increases over time. Buyers are willing to pay more for reliable, long-term nuclear power.
What risks still limit advanced reactor growth despite the momentum?
Costs, permitting, siting, and supply chains remain major hurdles. Recent SMR projects show how expensive and complex development can be, making long-term nuclear contracts a bridge between near-term cash flow and future growth rather than a quick win.
