LIHI recertifies three low-impact hydroelectric facilities in the U.S.

The Low Impact Hydropower Institute recently announced it had recertified three hydroelectric facilities through its low-impact certification program. They are:

Deer Island Project, from Aug. 6, 2019, through Aug. 5, 2029

Androscoggin Project, from Sept. 25, 2019, through Sept. 24, 2024

Dodge Falls Project, from June 1, 2019, through May 31, 2024

The 2-MW Deer Island Project generates hydropower at the Massachusetts Water Resource Authority’s Deer Island Wastewater Treatment Facility. The facility ahs two nominal 1-MW Kaplan units and an average head of about 29 feet. Water flows from the treatment facility into an effluent channel. It then flows through a turbine and discharges into an outfall shaft that empties into Massachusetts Bay. The project received a conduit exemption from the Federal Energy Regulatory Commission.

The 29.4-MW Androscoggin project is owned and operated by Andro Power LLC and is on the Androscoggin River in Maine. It is composed of four separate run-of-river developments: 3.1-MW Jay, 8.8-MW Livermore, 10.4-MW Otis and 7.1-MW Riley. Jay was completed in the early 1900s and features six turbine-generator units. Livermore also was completed in the early 1900s; the original powerhouse contains eight identical units, and a new powerhouse constructed in 2004 houses a single turbine-generator unit. Otis was completed in 1984 with two turbine-generator units. The six turbine-generator units at Riley were installed in 1982. Together, the four plants generate a total of nearly 121,000 MWh of electricity.

The 5-MW Dodge Falls project is on the Connecticut River between New Hampshire and Vermont and is owned by Dodge Falls Associates LP. The dam was originally constructed to provide waterpower to a paper mill. The run-of-river Dodge Falls project began operating in 1990, and the paper mill was shut down in 2000. As Dodge Falls is 4 miles downstream from the McIndoes project, its inflow is controlled by the flow discharged from the upstream powerhouse. Dodge Falls generates an average of 25,700 MWh annually.

LIHI is a non-profit organization dedicated to reducing the environmental impacts of hydropower generation through the certification of hydropower projects that have avoided or reduced their environmental impacts pursuant to the institute’s criteria. The voluntary LIHI program is designed to help consumers identify environmentally sound, low-impact hydropower facilities. Certification under the program means the owner can market the project as a certified low-impact facility.

LIHI has granted Low Impact Certification to nearly 200 hydropower facilities located in 23 states and on 84 rivers and representing 15,000 GWh of clean, climate-friendly generation since 2000.
