LG&E and KU Partner with X-energy to Explore Xe-100 SMR Deployment Under $75M Pilot
PPL•Louisville Gas & Electric and Kentucky Utilities, PPL subsidiaries, began feasibility studies with X-energy to assess deployment of Xe-100 small modular reactors in Kentucky for grid reliability and large-load customers. The collaboration leverages a $75 million Nuclear Reactor Site Readiness Pilot Program offering up to $25 million per project.
1. Collaboration Scope
Louisville Gas & Electric and Kentucky Utilities, both PPL subsidiaries, have initiated early feasibility activities with X-energy to evaluate the deployment of the Xe-100 small modular reactor in Kentucky. The effort focuses on supporting long-term grid reliability and meeting demand from large-load customers, including data centers.
2. Pilot Program Details
Kentucky’s Nuclear Reactor Site Readiness Pilot Program allocates a total of $75 million in grants, with up to $25 million available per project to fund early site studies, permitting applications, and licensing efforts. The program also permits regulated utilities to recover uncovered permitting and licensing costs through the Public Service Commission.
3. X-energy Xe-100 Reactor Technology
The Xe-100 is an 80 MWe high-temperature gas-cooled reactor designed for modular deployment. A four-unit configuration delivers 320 MWe for regional utilities and large-load customers, while a twelve-unit setup can supply gigawatt-scale power for metropolitan areas and hyperscale infrastructure, with each reactor coming online independently.
4. Implications for PPL
Exploring SMR deployment could diversify PPL’s generation mix and strengthen its position in clean energy markets. Successful integration of Xe-100 technology may enhance long-term value by adding reliable, low-carbon baseload capacity and supporting growth in demand-driven sectors.
