Description: 

The RITE Pilot Project, licensed under FERC P-12611, builds on the successful RITE demonstration that was developed from 2006-08. The RITE Pilot consists of:

  1. A Project boundary of approximately 21 acres, including shoreline lands for interconnection;
  2. Project works consisting of up to:
    1. Thirty 35 kW, 5-meter diameter axial flow Gen5 Kinetic Hydropower Systems (KHPS) turbines;
    2. Ten TriFrame mounts, each of which will support 3 KHPS turbines;
    3. 480-volt underwater cables from each turbine to the shoreline switchgear vaults that will interconnect to a control room and interconnection points, and
    4. Appurtenant faculties for navigation and operation.

In accordance with the FERC Pilot Project License, the RITE Pilot Project will be installed in stages with commensurate environmental monitoring as follows:  

  • Install A: Two Gen5 Turbines on existing monopiles (reconfigured as under Install B-1)
  • Install B-1: Install a single TriFrame, consisting of three Gen5 turbines (Planned 2018)
  • Install B-2: Install up to three additional TriFrames, consisting of up to nine Gen5 turbines (Potential) 
  • Install C: Install up to six additional TriFrames, consisting of up
Location: 

East Channel of East River - tidal strait connecting Long Island Sound to Atlantic Ocean through New York Harbor at New York, NY, USA. Turbines installed at 10 meters depth.

Process Status: 

As of November 2016, a TriFrame with 3 Gen5 5m KHPS turbines is planned for installation under the RITE Pilot during 2018-2019, under provision of the FERC license as Install B-1. Pre-project construction has commenced and the TriFrame is undergoing a design cycle. Environmental monitoring (RMEE) plans under adaptive management will be executed in conjunction with the project.

Licensing Information: 

The 1.05 MW RITE Project (RITE Pilot) was licensed under the first FERC Hydrokinetic Pilot Project License, which was issued in conjunction with a 401 Water Quality Certification (WQC) permit issued by NYSDEC, an underwater lands lease issued by NYSOGS, and CZMA concurrence issued by NYSDOS. The RITE Pilot consent process began in late 2008 and the FERC license was issued January 2012. Throughout the consent process the following key organizations have been involved: NYSDEC, NYSDOS, USACE, USEPA, NMFS/NOAA, USCG, NYSOGS, and others. Public involvement included stakeholder meetings, work groups, public meetings, and public notice and comment periods. The following is a brief procedural history:

  • November 25, 2008: FERC Draft License Application filed for RITE Pilot
  • May 1, 2009: Notice and Letter issued grating waivers for use of Pilot Procedures
  • December 29, 2010: FERC Final License Application filed for RITE Pilot
  • January, 2011: NYSDEC, USACE Section 10/404/401 Permit Applications filed and CZMA filed
  • February 2, 2011: REA Notice issued; June 6, 2011: Comments filed
  • August 2011: NYSDEC WQC (401/404) public comment; October 2011: Comments filed
  • December 13, 2011: NYSDEC grants 10-year Water Quality Certification (WQC) (301/404)
  • January 23, 2012: FERC 10-year Hydrokinetic Pilot Project License issued, incorporating WQC terms
  • USACE Section 10/404 Permit: pending
Key Environmental Issues: 

Under an adaptive management framework working with local and federal natural resource agencies, Verdant Power will execute a comprehensive set of environmental monitoring and safeguard plans to ensure the safe operation of the RITE Pilot Project. These efforts include a set of environmental monitoring plants - the RITE Monitoring of Environmental Effects (RMEE) plans - which will be conducted throughout the phased development of the project to observe the interaction of aquatic species with the natural environment, particularly as the project grows to include larger arrays of operating turbines. These plans are extensions of prior RITE monitoring efforts, which showed no evidence of negative impact to the local environment in the project area.

Aquatic Life - The East River supports a variety of resident and migrating aquatic species, including winter flounder, Atlantic tomcod, striped bass, bay anchovy, and American eel. The two relatively common fish species are the Atlantic silverside and the northern pipefish.

Terrestrial Resources - A variety of birds inhabit the area, with some using the East River for feeding or resting. Dominant species include the double-crested cormorant and a variety of gulls.

Rare, Threatened and Endangered Species - Two federally-listed endangered fish species, the shortnose sturgeon and the Atlantic sturgeon, are known to traverse the area. The threatened green turtle and loggerhead turtle, and the endangered Kemp's ridley turtle and leatherback turtle may be present in the area. The Biological Assessment for the RITE Project rated the probability for interaction with these species to be low. However, as part of its monitoring, Verdant Power will continue to observe and report any interaction between these species and the project during operation.

Roosevelt Island Tidal Energy (RITE) Project Pilot is located in United States of America.

Post-Installation Monitoring: Roosevelt Island Tidal Energy (RITE) Project Pilot

General Description:

RITE Pilot environmental monitoring plans: RITE Monitoring of Environmental Effects (RMEE) plans as approved January 2012.

 

All RMEE plans are subject to the adaptive management process throughout the term of the pilot license.

ReceptorMonitoring Program Description Design and Methods Results Status
  • Fish and Fisheries

RMEE-1: Seasonal Fixed Hydroacoustics - Deploy seasonal fixed hydroacoustic instruments to provide a picture on the meso and macro presence and abundance of fish targets in the Pilot area, and movement of fish relative to a turbine field at the meso and macro scales at a known migration period. Coupled with other elements of this plan, the interaction and effects of an operating KHPS can start to be understood.

  • Fish and Fisheries

RMEE-2: Seasonal DIDSON Observation Monitoring - Deploy seasonal Dual-Frequency Identification Sonar (DIDSON), a multi-element sonar that provides video-like images of underwater objects  to provide real-time observation of fish behavior near operating KHPS during a seasonal period of known fish abundance. Specifically, the goal is to provide imaging of any fish-KHPS interaction, both spatial and temporal, at the micro scale around a rotating turbine to build the understanding of fish interaction near operating machines.

RMEE-3: Seasonal Species Characterization Netting - The objective of netting is to provide a set of net capture data, during May through December, with more effort during the seasonal period (mid-September through mid-December) of elevated fish abundance in the project vicinity to provide species characterization information in the area of the RITE pilot, and to support the interpretation of the past and future DIDSON monitoring and hydroacoustic evaluations above.

Netting during slack tide - May/June, July/August and 6 days between Sept. 15 - Dec. 15.

  • Threatened and Endangered Species

RMEE-4: Tagged Species Detection - The objective of this plan is to provide new and unique detections on the potential presence of the proposed ESA listed Atlantic sturgeon, ESA listed shortnose sturgeon, along with striped bass, bluefish, winter flounder, and 27 other species that have been acoustically tagged. Detection would occur in both the east and west channels of the East River, proximate to the RITE Pilot project boundary. Little is known of the presence and pattern of these ESA species in the vicinity of the Pilot project, and so this data will support further understanding of the effects of the operation of the RITE Pilot project.
