Class I Hydropower in Connecticut

The Connecticut legislation establishing the state's RPS created two classes of renewable energy (Classes I and II) and required that all electricity suppliers in the state include a certain percentage of each class in their electricity mix. In July 2003, the Connecticut legislature amended the RPS statute to include certain types of "run-of-the-river" hydropower as both a Class I and Class II source.

In order to qualify as a Class I renewable energy source, a hydropower operation must be "a run-of-the-river hydropower facility" that has "a generating capacity of not more than five megawatts, does not cause an appreciable change in the river flow, and began operation after July 1, 2003."

Small hydro projects are perfect for Connecticut's rivers and streams. Although there is a need to be conscious of the environmental factors, Connecticut can carefully plan for small hydro installations to be apart of its overall renewable generating capacity while ensuring safe fish passage and riparian ecosystem health. If you have a site that is already licensed for hydro power and would like to consider developing the resource, please contact us for more information. See Hydro in Connecticut for current projects.
