March 21 (Renewables Now) - US energy company Avista Corp (NYSE:AVA) will be buying power from the Rattlesnake Flat wind farm project in Washington of US power producer Clearway Energy Inc (NYSE:NYLD).
Avista said Tuesday it will enter into a 20-year power purchase agreement (PPA) for 50 average megawatts (MWa), or as much as 144 MW of nameplate capacity, securing additional renewable energy, capacity and environmental attributes to offset higher priced market purchases.
The power supply contract award to Rattlesnake Flat follows a request for proposals released in June 2018.
“Recent market changes, including reductions in the cost of wind power facilities and tax incentives that remain in effect, have combined to make this an excellent time to acquire long-term output from a cost-effective wind resource,” said Jason Thackston, senior VP of Energy Resources for Avista. He noted that the fact that the wind park is located in the company’s service territory comes as an added benefit.
Rattlesnake Flat is a fully permitted project under development in Adams County. It will be built near Lind on privately owned land and connect into Avista’s electric system via the Lind/Washtucna transmission line.
Supply under the PPA is to commence in 2020. The wind power volumes are expected to meet the needs of about 37,600 households. Avista is to recover the cost of the green power it buys through its retail rates.
