Deer Rips/Androscoggin No. 3 Projects – LIHI No. 163, ME
The Gulf Island – Deer Rips Hydroelectric Project is located on the Androscoggin River in Lewiston and Auburn, Maine. There are numerous other hydroelectric projects on the Androscoggin River in New Hampshire and Maine. The Project consists of two developments: Gulf Island and Deer Rips / Androscoggin No. 3 (A-3). Only Deer Rips and A-3 are included in the LIHI certification. The Project is owned by Brookfield White Pine Hydro (Brookfield Renewable Energy Group).
Deer Rips was constructed in 1904 and A-3 in 1928. The Project was most recently relicensed by FERC in 2006. The Deer Rips dam is a three-section structure, 933 feet long with a 738 -foot-long spillway section and maximum height of 50 feet. The spillway is topped with a 4.5-foot-high rubber dam. The 130-acre impoundment extends about 1.3 miles upstream to the Gulf Island development. The dam contains a headworks section of the Deer Rips powerhouse, located on the west side of the river. A 94-footlong headworks section on the west side of the dam has a waste gate that discharges just below the dam and 8 other gates that lead to a 650-foot-long power canal. The canal creates a bypassed reach approximately 700 feet long. The Deer Rips powerhouse contains seven turbines: five horizontal twin-runner Francis units, and 2 vertical Francis units with a total capacity of 7.245 MW. A forebay on the east bank of the river leads to a headworks section of the Androscoggin No. 3 powerhouse which contains a single vertical fixed blade propeller unit with a capacity of 4.5 MW.
