LIHI Certificate #178 - Freedom Falls Hydroelectric Project, Maine
Freedom Falls hydroelectric project is located in Freedom, Maine, a small rural town in Central/Mid-Coast Maine 16 miles west of Belfast, 20 miles east of Waterville, and 30 miles northeast of Augusta in Waldo County.
The run-of-river project received a FERC exemption (#14421) in 2013 to rehabilitate the old mill that had fallen into complete disrepair and to add hydro generation. The site now houses one turbine with 35 kW capacity. A school and The Lost Kitchen restaurant also occupy the mill building.
The dam was originally built in 1834 to power a gristmill and later a wood turning mill, later abandoned in 1967. The dam is a stone-masonry concreted-capped structure about 12 feet tall and 90 feet long. There are no flashboards. The dam creates a small 1.6-acre mill pond at the downstream end of Sandy Pond which is a shallow warmwater pond with a total area of 435 acres. Water is conveyed from the dam to the powerhouse by a 60-foot long penstock that creates a short bypassed reach in Sandy Stream. More information about the project can be found HERE.
In December 2019, Natel Energy installed their latest turbine, the Restoration Hydro Turbine (see HERE). This new Francis turbine replaced the Natel linear Pelton machine installed in 2017. Natel wanted to have their latest, more efficient and reliable design at this site, which is their demonstration site on the east coast. The project generates approximately 65 MWh per year. The project includes upstream and downstream passage facilities for American eel.
