Harrington Park, New Jersey (October 19, 2016) – On September 23, 2016, the Low Impact Hydropower Institute (LIHI) received a complete application from Brookfield Renewable Energy Group for the Low Impact Certification of the Safe Harbor Project, FERC No. 1025, located on the Susquehanna River in Lancaster and York counties, Pennsylvania.


Project Name Safe Harbor
Owner Brookfield Renewable Energy Group
State Pennsylvania
Location Located on the Susquehanna River in Lancaster and York counties, Pennsylvania.
Installed Capacity 380.39 MW
Average Annual Generation 1,138.6 GWh
Facility Type Peaking
FERC No. 1025

Pursuant to the October 28, 1998 Order Amending License, the project works consist of a concrete gravity dam 75 feet high and 4,869 feet long; an integral powerhouse containing 14 generating units with a total installed capacity of 380,390 kW; transmission interconnections; and appurtenant facilities. The project reservoir (Lake Clarke) extends 10 miles upriver, with a total surface area of 7,360 acres at the normal maximum reservoir elevation of 227.2 ft msl.


The Project operates in peaking mode except when flows exceed 110,000 cfs, at which point the Project operates at full capacity. Project operation is coordinated with downstream hydroelectric plants and the overall Pennsylvania-New Jersey-Maryland (PJM) Interconnection System. During peaking operation, the Project impoundment provides 47,850 acre-feet active storage capacity in the upper 9.2 feet of the reservoir. The Project’s storage capacity is also used during predicted flood events on the river to reduce flooding impact at and downstream of the Safe Harbor Project, and in the winter to minimize the damage from ice jams during periods of critical flow, ice cover and differential head across the ice jam. When conditions are favorable, ice jams that form in the narrow river section approximately 4.5 miles above the Safe Harbor Dam can be broken up by varying the reservoir surface elevations.



LIHI is seeking public comment on this application. Specifically, we are interested in knowing whether you think the Safe Harbor project meets the LIHI Low Impact Certification Criteria. The Safe Harbor application is subject to review using the Criteria in the LIHI Certification Handbook of 2014.  Please review the program and criteria in LIHI’s 2014 Handbook and then review the Project’s 2016 application materials posted on the project page. Comments that are directly tied to specific LIHI criteria (flows, water quality, fish passage, etc.) will be most helpful, but all comments will be considered. Comments may be submitted to the Institute by e-mail at comments@lowimpacthydro.org with “Safe Harbor Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, PO Box 194, Harrington Park, New Jersey 07640. The 60 day public comment period begins on October 19, 2016.  Comments must be received at the Institute on or before 5 pm Eastern time on December 18, 2016 to be considered. All comments will be posted to the web site and the applicant will have an opportunity to respond.  Any response will also be posted.
