Dahowa Hydroelectric Project

Harnessing flows from the Batten Kill River, the Dahowa Hydroelectric Project overlooks Dionondahowa Falls in New York’s Capital Region. The current station was built in 1991, utilizing 110 feet of head and a vertical Kaplan turbine to produce enough to power more than 3,000 homes.


Newport Hydroelectric Project

Located along the scenic and
biologically-rich Clyde River of northern Vermont, the Newport hydroelectric project has been powering the region since the 1930s. Today, this run-of-river hydroelectric facility consists of a dam, a penstock system, upstream and downstream fish passage and a powerhouse containing three hydroelectric generating units. The facility has a capacity of four megawatts and can generate clean power for over 2,100 average households per year. A 150-kilowatt solar photovoltaic system is co-located with the hydroelectric station.


West Charleston Hydroelectric Project

The 0.675 MW West Charleston hydroelectric facility is located on the Clyde River in northern Vermont. The facility was originally constructed in the early 1900s and operated for nearly a century before being abandoned. With the value of renewable power increasingly recognized a new powerhouse was constructed in 2010 and the facility was returned to operation.


Glendale Hydroelectric Project

The Glendale hydroelectric facility is comprised of five units totaling 1.14 megawatts (MW) of capacity. It is located on mile 122 of the Housatonic River in the town of Stockbridge, Berkshire County, MA. The facility offers recreational access and parking for canoeing and bank fishing. Its powerhouse is listed in the National Register of Historic Places in recognition of its engineering and industrial uses dating back to 1900.


Texon Hydroelectric Project

The Texon hydroelectric facility has a rated capacity of 1.5 MW from a single unit located on mile 24 of the Westfield River in Russell, Hampden County, MA. It contains river access for canoeing and fishing. The facility has completed a rigorous certification process and been recognized by the Low Impact Hydropower Institute for its environmental benefits.


Quinebaug-Five Mile Pond Hydroelectric Project

Utilizing dams built during the industrial revolution, The Quinebaug and Five Mile Pond hydroelectric projects were built in the late 1980’s utilizing dam infrastructure developed to support early manufacturing in the region. The projects are located in northeastern Connecticut, upstream of Gravity’s Wyre Wynd project and near the confluence of the Five Mile and Quinebaug Rivers. Collectively, the two projects generate enough clean power to electrify approximately 1,000 New England households each year.


Moomaws Hydroelectric Project

Located in southern Virginia on the Maury River, the Moomaws hydroelectric project has been generating power since 1984, utilizing a stone masonry gravity dam originally constructed in 1842. The project consists of a powerhouse and single siphon turbine.


Seneca Falls Hydroelectric Project

The Seneca Falls Project has been intertwined with the history and growth of the Finger Lakes region of New York since it first started generating clean power nearly a century ago. Located in historic Seneca Falls, NY, birthplace of the women’s rights movement, the project takes advantage of excess water flow and elevation created by the construction of the Cayuga-Seneca Falls Canal in the early 1900s. Today, this 8 MW project generates enough electricity to power approximately 1,800 New York households.


Waterloo Hydroelectric Project

The Waterloo Project is situated on the Cayuga-Seneca Falls Canal in the heart of the Finger Lakes region of New York. Located in downtown Waterloo, NY, home of the first Memorial Day celebration, this 2 MW project first generated clean power a hundred years ago. Neighboring Tompkins County entered into a long-term operating agreement for the project’s generation, allowing it to meet 63% of its annual electric consumption with renewable energy.


Wyre Wynd Hydroelectric Project

The Wyre Wynd Hydroelectric Project is located on the Quinebaug River in Jewett City, Connecticut. Originally designed to support a textile mill in the 1800s, the station now produces enough clean energy to power 2,000 homes.


Dog River Hydroelectric Project

Dog River Hydroelectric Project is located in Northfield, Vermont, in the Nantanna Mill complex. The plant was originally commissioned in 1983 and now generates approximately 650,000 kilowatt-hours of clean energy each year.


Stillwater Hydroelectric Project

Completed in 1993, Stillwater Hydroelectric Project is located on the Hudson River just north of Albany. The facility represents an excellent example of high flow, low head hydro generation in upstate New York.


Comtu Falls Hydro Project

Located on the historic Black River, the Comtu Falls Hydroelectric Project generates clean electricity in downtown Springfield, Vermont. The hydroelectric plant generates 2.5 million kilowatt hours of clean energy each year — enough to power 372 homes.

Pawtucket No. 2 Hydro Project

Pawtucket No. 2 is housed in the historic Bridge Mill Power Plant, which has provided clean energy to Pawtucket from the Blackstone River since the late nineteenth century. The facility was repowered in 1981, received certification as a low-impact site in 2014, and generates enough electricity to power 672 homes annually.

Saxapahaw Hydro Project

The Saxapahaw Hydroelectric Project is located on the Haw River and was the first independently owned clean energy generator in the state. Today, the project produces almost 5,600,000 kilowatt hours of clean electricity a year.

Chittenden Falls Hydro Project

The site of Columbia County’s first paper mill in 1820, Chittenden Falls Hydroelectric Project is located on the Kinderhook Creek in Stuyvesant, NY. The plant was repowered in 1981 and under a partnership with Skidmore College, has been refurbished by Gravity.  Producing 20% of Skidmore’s load, it also houses a remote classroom and exhibit area.

Mill Pond Hydroelectric Project

Located in the foothills of the Catskill Mountains, the Mill Pond Hydroelectric Project produces almost 3,000,000 kilowatt hours of clean electricity for the Hudson Valley. The plant was commissioned in 1987.
