Lewis Ridge Pumped Storage, LLC; Notice of Application Ready for Environmental Analysis and Soliciting Comments, Recommendations, Terms and Conditions, and Prescriptions
Published Date: 2/6/2026
Notice
Summary
Lewis Ridge Pumped Storage, LLC wants to build a new hydroelectric project near Blackmont, Kentucky, and the government is now ready to review its environmental impact. Local communities, energy users, and environmental groups can share their thoughts by April 3, 2026. This project could bring new clean energy but also needs careful planning to protect the area.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
New 308 MW Pumped Storage Plant
The Lewis Ridge Project would include two 154-megawatt reversible pump-turbines (308 MW total) and is described as able to produce about 717,000 megawatt-hours (MWh) of peak energy annually. The facility would operate an 8-hour generation cycle at 266 MW and require 340 MW to refill the reservoir, connecting to the grid via a 2.5-mile, 161-kilovolt transmission line.
River Water Use for Reservoir Filling
The project would require about 2,808 acre-feet of water for initial fill and about 149 acre-feet annually for maintenance. It would use all Tom Fork River flows above 2.8 cubic feet per second (cfs) for fill and maintenance and about 10% of the mean monthly flow in the Cumberland River as needed.
Private Land, Inundation, and Road Work
The proposed project boundary would enclose about 148 acres of privately owned land (primarily Asher Land and Mineral, LLLP) and about 16 additional private parcels, and the lower reservoir would inundate part of the 1.8-mile-long Tom Fork River. Construction would include about 7.1 miles of permanent roads, 4 miles of temporary roads, and two spoil disposal sites that would later be seeded and revegetated.
