LIHI Certificate #165 – Hanover Pond Dam Project, Connecticut
The Hanover Pond Dam Hydroelectric Project is located on the Quinnipiac River in Meriden, CT. Historically, over 100 Industrial Revolution-era dams existed on the Quinnipiac River. A dam was originally built at the approximate location of the existing dam in the 1850s and Hanover Pond was impounded to provide hydropower to the former Meriden Cutlery Factory. The factory buildings were located downstream and south of the facility site. All buildings associated with the factory, which closed in the 1920s, were demolished in the 1930s. The only known portions of the factory complex on the site were the original timber crib dam (now demolished and fully rebuilt) and a former north-south oriented water intake canal that once traversed the western portion of the Facility Site (abandoned and filled sometime between 1934 and 1951). The dam was reconstructed by the City of Meriden in 2005-2006 at which time an upstream fish passage facility was installed. Both the dam and fishway are owned by the City.
On May 19, 2016, FERC issued an Exemption from Licensing as Project No. P-14550. The powerhouse and turbine were constructed in 2016-2017 and the project became operational in late February 2017.
The Project is the first hydroelectric facility in the United States to employ the Archimedes Screw Turbine (AST) for power generation. The AST uses the head of an existing, previously non-powered dam to produce electricity through a slowly turning screw attached to a variable speed gear box and generator, which distributes the electricity produced out to the grid. The AST is known for its ability to pass fish safely downstream and was chosen for installation at the project with support from state and federal resource agencies because of this attribute. Studies are still in progress to confirm effective downstream passage for all species.

January 6, 2020: The decision to certify the Hanover Pond Dam project became final after the close of the appeals period on November 27, 2019 with no appeals filed. The Certification is LIHI #165 with a term from August 12, 2019 – August 11, 2024. The Certification includes three conditions:
- Condition 1: The facility Owner shall provide copies of the final 2019 and 2020 water quality monitoring reports in annual compliance submittals to LIHI in the compliance year after each study’s results become available. All agency and FERC correspondence and/or approvals of the results shall also be provided.
- Condition 2: The facility Owner shall provide copies of the upcoming upstream and downstream passage study reports in annual compliance submittals to LIHI in the compliance year after each study’s results become available. All agency and FERC correspondence and/or approvals of the results shall also be provided. The Owner shall consult with resource agencies on any modifications and/or additional mitigation needed to ensure that downstream passage is effective. The Owner shall submit a plan and schedule of approved measures to LIHI. LIHI reserves the right to modify this certification as necessary to assure that its downstream fish passage standards are being met.
- Condition 3 (optional): If at any time prior to six months before the expiration of the Certification term, Condition 2 is deemed satisfied, LIHI will determine whether or not to award a PLUS standard for downstream passage and extend the Certificate term for three additional years.
October 28, 2019: On October 25, 2019 the Low Impact Hydropower Institute preliminarily approved Low Impact Certification for the Hanover Pond Dam Hydroelectric Project.
This decision is preliminary pending the 30-day appeal window. Only those who commented on the initial application during the 60-day comment period are eligible to file an appeal. Such appeal needs to include an explanation as to how the Project does not meet the LIHI criteria. Appeal requests can be submitted by email to email@example.com with “Hanover Pond Hydroelectric Project” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 329 Massachusetts Ave, Suite 6, Lexington, MA 02420. All requests will be posted to the website. The applicant will have an opportunity to respond and any response will also be posted. Requests must be received by 5 pm Eastern time on November 27, 2019. The full application and reviewers report are available below.
If no appeal requests are received and the decision becomes final, the Certification term for the Project (pending LIHI #165) will be August 12, 2019 for a term of five (5) years, which will expire on August 11, 2024.
August 13, 2019: The Low Impact Hydropower Institute has received a complete application for Low Impact Certification of the Hanover Pond Dam Hydroelectric Project. LIHI is seeking public comment on this application. Specifically, we are interested in knowing whether you think the Project meets the LIHI Low Impact Certification Criteria, as revised in the 2nd Edition Handbook. Please review the program and criteria in LIHI’s revised Handbook and then review the Project’s application materials below.
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 firstname.lastname@example.org with “Hanover Pond Dam Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 329 Massachusetts Avenue, Suite 6, Lexington, MA 02420. Comments must be received on or before 5 pm Eastern time on October 12, 2019 to be considered. All comments will be posted to the web site and the applicant will have an opportunity to respond.
