The Hemlock Hollow Wind Project will provide significant new revenue to the community, optimizing a unique landscape to sustain Cattaraugus County’s energy leadership, while creating local partnerships that support the community.

  • The Project is expected to provide a preliminary estimate of tens of millions of dollars in local revenue to the Towns of Allegany, Portville, and Olean; Cattaraugus County; local school districts and fire districts; and landowners participating in the Project.
  • The towns are expected to receive a preliminary estimate of hundreds of thousands of dollars annually through the development of a Host Community Agreement, and additional estimated annual payments of tens of thousands of dollars will be distributed to the community through a Shared Community Payment Program. 
  • The Hemlock Hollow Wind Project will become one of the first renewable projects in New York State co-located alongside active oil and gas infrastructure. The clean power generated from the Project will contribute to a more diverse and reliable energy mix to support the State.
  • Liberty Renewables prioritizes partnering with local communities through donations, scholarships, and workforce development training as an essential component of successful wind project development. Local jobs generated by renewable energy projects, such as the Hemlock Hollow Wind Project, create opportunities for local graduates to work and directly benefit their home communities.
