FERC seeks comment on permit app for hydro project in New Hampshire

The Federal Energy Regulatory Commission on April 21 went out with a public notice on a March 20 application from Murphy Dam LLC for a preliminary permit under which it would study the feasibility of the Murphy Dam Hydroelectric Project, to be located on the Connecticut River near Pittsburg in Coos County, New Hampshire.

The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the three-year permit term.

The proposed project would include: an existing earthen embankment dam; an adjacent concrete spillway with a stoplog and flashboard crest elevation of 1,385 feet National Geodetic Vertical Datum (NGVD); the existing 2,020-acre Lake Francis; a new steel penstock connected to an existing 916-foot-long, steel-lined concrete outlet conduit and concrete intake structure; a new powerhouse containing one Kaplan turbine-generator unit having a total installed capacity of 3 MW; a new riprap-lined tailrace; and a new 1,600-foot-long, 12-kV transmission line connecting the powerhouse to the Public Service of New Hampshire distribution system. The estimated annual generation of the Murphy Dam Project would be about 12,400 megawatt-hours.

The existing Murphy Dam and appurtenant works is owned by the New Hampshire Department of Environmental Services.

The applicant contact is: Mark Boumansour, Murphy Dam LLC, c/o Gravity Renewables Inc., 1401 Walnut Street, Suite 220, Boulder, CO 80302, phone: (303) 615- 3101, info@gravityrenewables.com. 

The deadline for filing comments, motions to intervene, competing applications (without notices of intent), or notices of intent to file competing applications is 60 days from the issuance of this April 21 notice.
