The Federal Energy Regulatory Commission has issued a preliminary permit to Grid Balance Hydropower LLC for the proposed 400-MW Packer-Banks Pumped Storage Project, to be located in Carbon County, Pennsylvania.
The proposed project would consist of:
- New 9,500-foot-long, 80- to 120-foot-high roller-compacted concrete and/or rockfill dam or dike forming an upper reservoir with a total storage capacity of about 9,300 acre-feet
- A lower reservoir with three options of dam/dike size and location and water storage capacity
- A 5,500-foot-long tunnel and/or penstock connecting the upper and lower reservoirs
- A powerhouse containing four turbine-generator units
- A transmission line connecting the powerhouse to an existing 230-kV transmission line
Initial fill and makeup water for the project would come from a nearby abandoned mine draining source.
The project would have annual generation of 1.68 million MWh.
The purpose of a preliminary permit is to preserve the right of the permit holder to have the first priority in applying for a license for the project that is being studied.
FERC issued a 48-month preliminary permit for the project, effective Nov. 1, 2019.
