Summary
Marlow Hydro LLC wants to build a small hydroelectric project on the Ashuelot River in Marlow, New Hampshire. The government is asking the public to share their thoughts by April 17, 2025, before deciding on the project. This could bring clean energy to the area, but folks have a chance to speak up early in the process.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 0 costs, 1 mixed.
Operator proposes raising bypass flow
Marlow Hydro proposes to continue run-of-river operations and to increase the bypass flow over the dam from 5.2 cubic feet per second (cfs) to 14.5 cfs. The project has a 225 kilowatt installed capacity and averaged 552 megawatt-hours annually from 2016–2020; current required continuous flows are 23 cfs downstream and 5.2 cfs over the dam.
