LG&E, Kentucky Utilities, X-energy SMR plan: grid and baseload notes for engineers
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
LG&E and Kentucky Utilities, subsidiaries of PPL Corporation, are partnering with X-energy to assess deployment of the Xe-100 small modular reactor (SMR) in Kentucky to supply baseload power for large loads such as data centres and maintain long-term grid reliability. Early feasibility work will tap the state’s new $75 million Nuclear Reactor Site Readiness Pilot Program, which can fund up to three nuclear site studies at $25 million each for permitting and licensing. The initiative signals potential future nuclear-backed power for energy-intensive industrial and mining operations in the region.
Technical Brief
- Nuclear Reactor Site Readiness Pilot Program provides $75 million for feasibility, permitting and licensing support.
- Up to three Kentucky nuclear projects can each access a maximum of $25 million in grants.
- Kentucky Nuclear Energy Development Authority, formed 2024, is mandated to build a state nuclear ecosystem.
- Kentucky Public Service Commission opened a 2025 case to define nuclear regulatory treatment and oversight.
- LG&E and KU frame nuclear within an “all-of-the-above” generation mix targeting reliability and affordability.
- X-energy positions Xe-100 deployment to leverage Kentucky’s existing skilled workforce and industrial base.
Our Take
The $75 million Nuclear Reactor Site Readiness Pilot Program, capped at three projects, effectively creates a competitive benchmark for other US utilities like LG&E and Kentucky Utilities that are exploring SMRs, signalling what scale of early-stage support states may need to keep pace with nuclear-ready jurisdictions.
Kentucky’s move, backed by the Kentucky Nuclear Energy Development Authority and overseen by the Kentucky Public Service Commission, positions the Commonwealth within a small subset of US regions in our Infrastructure coverage that are explicitly preparing grid and regulatory frameworks for advanced reactors rather than only life-extending existing nuclear assets.
