The Hawaii County Department of Water Supply is considering building a wind farm to power its South Kohala wells.
The department would lease about 80 acres of state land next to its Lalamilo wells and have a developer build the wind mills.
The project would create 50 construction jobs and three permanent jobs.
Department energy management analyst Julie Myhre says a wind farm built on the site in the mid-1980s has been decommissioned and the site has been cleaned up.
West Hawaii Today reported Monday the wind farm would save about $500,000 a year in electricity costs for the next 20 years.
A department spokeswoman says it’s too early to tell if the facility would generate excess energy to sell to Hawaii Electric Light Co.
