On November 22, 2010, Pennamaquan Tidal Power, LLC filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of the Pennamaquan Tidal Power Plant Project to be located on the Pennamaquan River and Cobscook Bay, Washington County, Maine. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owners' express permission.
The proposed project would consist of: (1) A 692-acre tidal area of the Pennamaquan River and Cobscook Bay; (2) two new impervious core, sand, and crushed rock embankments, one 689-feet-long and another 164-feet-long; (3) a new 505-foot-long concrete modular wall panel extending about 11 feet above mean sea level consisting of: (a) New concrete support columns; (b) a new boat lift; and (c) a new powerhouse with four reversible bulb generating units with a total capacity of 21.1 megawatts; and (4) a new 35 kilovolt, 2.5-mile-long transmission line. The project would produce an estimated average annual generation of about 66,400 megawatt-hours.
Deadline for filing comments, motions to intervene, competing applications (without notices of intent), or notices of intent to file competing applications: 60 days from the issuance of this notice.
