CALGARY, Alberta (August 13, 2025) — Enverus Intelligence® Research (EIR), a subsidiary of Enverus, the most trusted energy-dedicated SaaS company that leverages Generative AI across its solutions, has released a report on repowering retired coal plants in order to accelerate clean, dispatchable capacity deployment. By leveraging existing infrastructure and interconnection access, bypassing greenfield delays dramatically shortens timelines and reduces permitting risk, making repowering a pragmatic bridge to a cleaner, more resilient grid. In the report, EIR identifies operators that hold highly strategic coal portfolios, with repowering potential unlocking hidden grid value and investment upside.
The technology selection hinges on regional and regulatory fit — natural gas repowers are fast and proven, while nuclear and enhanced geothermal systems (EGS) offer greater long-term upside if siting challenges are addressed. Geographic trends are also shaping technology viability.
“Our grid isn’t short on opportunity — it’s short on time. Repowering coal sites is one of the fastest levers we can pull to reintroduce firm capacity without waiting in long interconnection lines,” said Carson Kearl, EIR senior analyst.
“The shift to clean baseload will be won or lost on infrastructure reuse. Repowering isn’t just a cost play, it’s a political and logistical shortcut to growing 24/7 low-carbon power,” Kearl said.
Key takeaways from the report:
- A total of 14.6 gigawatts (GW) of U.S. coal capacity has been identified for high repowering potential with natural gas, with top-scoring sites located near key gas infrastructure.
- Operators with large, retired coal portfolios show the highest valuations for repowering potential, particularly where interconnection queue costs align favorably with available capacity. Several portfolios exceed 10 GW of retired assets, offering significant opportunities for redevelopment.
- EGS present strong repowering potential in regions with low energy costs and favorable geological conditions. A handful of operators hold project sites with suitability-weighted capacities exceeding 3 GW, positioning them well for early EGS deployment.
- Nuclear repowering opportunities are concentrated among operators with facilities located in high-value power markets and regions with strong growth prospects. Suitability-weighted capacities for nuclear repowering exceed 10 GW in some portfolios, indicating substantial long-term upside.
