k. Project Description: The Penobscot Mills Project consists of: (1) four hydropower developments (North Twin, Millinocket, Dolby, and East Millinocket; located between river mile 15 and river mile 2 on the West Branch) that include (a) water retaining features ( e.g., dam/spillway, flashboards/rubber dam, and dikes), (b) water conduits/canals and penstocks, (c) intake structures equipped with trashracks, (d) four powerhouses, and (e) transmission equipment ( e.g., transmission lines); (2) a pool-and-weir fish passage facility at North Twin; and (3) one storage development (Millinocket Lake Storage Development; located on Millinocket Stream). The total rated capacity of the project is 67.9 megawatts. The North Twin impoundment is at the upstream end of the Penobscot Mills Project and receives flow from the Ripogenus Project. Releases from the North Twin Development pass through three other developments ( i.e., Millinocket, Dolby, and East Millinocket). The Millinocket Lake Storage Development includes a pumping station through which water can be pumped to Ambajejus Lake (within the North Twin impoundment). Water not pumped to Ambajejus Lake is discharged to Millinocket Stream, which enters the West Branch at Shad Pond, downstream from the Millinocket Development, then passes through the Dolby and East Millinocket Developments. In addition to these developments, the project includes two battery energy sites that operate as a single Battery Energy Storage System to enhance system reliability.
The five developments that compose the Penobscot Mills Project are operated as an integrated system, along with upstream storage projects, including the Ripogenus Project No. 2572, to manage water levels and flows downstream from the project. GLHA operates the North Twin Development as a store-and-release facility, and uses storage in the Millinocket Lake Storage impoundment, as necessary, to maintain North Twin Lake levels. The two storage developments (North Twin and Millinocket Lake Storage) are located upstream of the run-of-release developments (Millinocket, Dolby, and East Millinocket). GLHA releases minimum flows from Millinocket Lake into Millinocket Stream, as well as a continuous minimum flow in the West Branch downstream from the North Twin Development. Additional details regarding the Penobscot Mills Project facilities and operations can be found in Exhibit A (Penobscot Mills Project) and Exhibit B of the license application, and can be access by following the instructions in paragraph l.
GLHA proposes to continue to operate: (1) the North Twin Development for generation and seasonal storage, with target impoundment elevations of 490.42 feet National Geodetic Vertical Datum of 1929 (NGVD 29) from May 1 through August 21 and 488.42 feet NGVD 29 from August 22 through October 15, as well as to provide flows necessary to meet the 2,000-cfs flow requirement in the West Branch downstream from Shad Pond; (2) the Millinocket Lake Storage Development to (a) maintain impoundment elevations between 470 feet and 480 feet NGVD 29, and (b) provide a minimum flow of 60 cubic feet per second (cfs), or inflow (seasonally), to Millinocket Stream; and (3) the Millinocket, Dolby, and East Millinocket Developments as run-of-release facilities. GLHA also proposes to continue to operate and maintain the upstream pool-and-weir fish passage structure at North Twin Dam, post lake level (for North Twin and Millinocket Lake Storage) and flow information on Brookfield's existing SafeWaters website, maintain the 200-foot conservation buffer and 100-foot vegetation buffer around the Millinocket Lake Storage, North Twin, Millinocket, and Dolby impoundments, and maintain Umbazooksus Lake as wetland and wildlife habitat. GLHA also proposes to release a year-round 200-cfs minimum flow from Stone Dam; provide American eel passage, conduct eel studies, and develop a fishway operations and maintenance plan; provide seasonal whitewater boating flows of 600 cfs in Millinocket Stream; and develop an updated wildlife management area plan, a recreation plan, a shoreline management plan, and a historic properties management plan.
