The Granite State Hydropower Association (GSHA) is a voluntary, non-profit trade association for the small-scale independent hydropower industry in New Hampshire.  Members of GSHA own, operate and manage 49 hydroelectric facilities located in 36 towns and cities throughout the state, totaling 54.9 megawatts (MWs). Member's facilities are 5 MWs or less.  

Small hydro plants are typically located at dams near old mill buildings or town centers that were constructed in the 1800’s or early 1900’s.  Many of these plants were redeveloped following the federal Public Utility Regulatory Policies Act (PURPA) of 1978.  Virtually all GSHA facilities are regulated by the Federal Energy Regulatory Commission (FERC), and all work closely with state agencies and local officials on matters of public safety.  GSHA members serve an important public safety function by maintaining the infrastructure at existing dams and monitoring water-flows – tasks that would otherwise be borne by state and local government and paid for by taxpayers.
