How HARRIS compares
With 76 MW of capacity, HARRIS ranks 10th among the 83 operating power plants Bywatts maps in Maine and 2nd of the 44 operating Hydro plants in the state. It accounts for about 12% of Maine's operating Hydro capacity and 1.8% of all operating capacity in the state. Nationally it is the 215th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1954, it is older than 64% of the 81 operating Maine plants with a recorded commissioning year. Its operator, BROOKFIELD WHITE PINE HYDRO LLC, runs 16 operating plants in Maine totaling 314 MW. It shares Somerset County with 8 other operating plants, including WYMAN HYDRO and ANSON ABENAKI HYDROS.
EIA-860 lists 4 generators at the site with 76 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 170 GWh in 2024 (a 25% capacity factor), down 19% from 2022. Its generators came online between 1954 and 1955.

Weather peril exposure
HARRIS is a 76 MW hydro power plant in Somerset County, ME, operated by BROOKFIELD WHITE PINE HYDRO LLC, commissioned in 1954. Somerset County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.5 of 5 at the 38th national percentile. Ice storm is the leading peril, rated Relatively High by FEMA at the 91st percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a hydro plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
