Halcyon Tidal Power through Pennamaquan Tidal Power, LLC (PTP) is planning to construct a power plant in Cobscook Bay, Washington County, Maine, the US.
The project involves the construction of a 25.6MW power plant with the installation of 17 turbines, each turbine having a maximum output of 1.6MW.
The project will include the construction of 492m tidal barrage or low dam across the Pennamaquan River between Leighton Neck and Hersey Neck south of Pembroke, which consists of: two 1.5m-thick concrete walls, one 166m-long and one 41m-long, located in the inter-tidal area at each end of the barrage; six 25m-long, 3m-thick concrete modular wall panels extending about 6.7m above mean low tide; a new 133.5m-long, 27.7m-high concrete powerhouse with 16 reversible bulb generating units with a total capacity of 24MW; and a 19.8m-long, 13.4m-wide steel boat lock integral with the powerhouse.
The project will also include the construction of a tidal basin (i.e., impoundment) with a surface area of 198ha at low tide and 349ha at high tide; a new 100m-long utility road providing access from Hersey Neck to the powerhouse; and the laying of new 35kV, 4km-long transmission line to Emera Maine’s substation in Pembroke, Maine.
Alstom SA was appointed as turbines supply contractor.
In October 2010, Federal Energy Regulatory Commission (FERC) has awarded a three year preliminary permit to carry out the study activities for the development and the permit expired on February 28, 2014.
On March 12, 2014, PTP filed an application for a successive preliminary permit to study the feasibility of the Project.
On September 25, 2014, the preliminary permit was issued to study the feasibility of the project.
On February 24, 2015, FERC issued a study plan determination (SPD) that approved 27 studies (11 with modifications) for the Project Integrated Licensing Process (ILP). SPD stated that the initial study report (ISR) is due on February 25, 2016.
In March 2015, Normandeau Associates and Alden Research Laboratory were appointed as environmental consultants.
On July 28, 2015, PTP filed a letter stating that it would not be performing studies in 2015 and provided a schedule for conducting studies in 2016 and 2017.
On January 21, 2016, PTP filed a letter indicating that it has not raised the funds necessary to begin the required studies and requested an additional one-year suspension of the ILP to examine financing options that would allow it to proceed with the project.
On February 10, 2016, Integrated Licensing Process (ILP) for the Pennamaquan Project was terminated by FERC.
