LIND â Commercial operations are now underway at Avista Utilities and Clearway Energy Group's Rattlesnake Flat wind farm in Adams County. Avista Utilities and Clearway Energy Group began construction in April of Rattlesnake Flat, which is located on 20,000 acres of privately-owned land near Lind. The 160-megawatt Rattlesnake Flat consists of 57 wind turbines that will provide enough energy to power 38,000 homes per year, officials said. The turbines connect to Avista's transmission grid as part of a 20-year purchase power agreement between the Spokane-based utility company and San Francisco-based Clearway Energy Corp. Avista Corp. CEO Dennis Vermillion said during a virtual ceremony on Tuesday that Rattlesnake Flat aligns with the utility company's goal of providing clean, reliable energy to customers at a reasonable cost.
