Four-year, $45 million upgrade nearing completion at Avista’s largest hydroelectric dam
In February Avista’s Noxon Rapids hydroelectric project, which generates clean, renewable energy reached a big milestone when the last of four original turbines to be replaced was installed. The four-unit, $45 million project started in July 2008 and is on schedule to be finished by spring 2012.
The upgraded units are expected to increase the total generating capacity of the dam by an estimated 30 megawatts. The upgrades enhance Avista’s ability to serve our customers because it lets us generate more power using the same amount of water – enough energy, in fact, to power more than 4,800 homes, or a town nearly the same size as Rathdrum, Idaho. Another benefit: this additional energy qualifies under Washington State’s Energy Independence Act (RCW 19.285) to meet Avista’s Washington state-mandated renewable portfolio standard (RPS) requirements.
Avista continues to generate or purchase about half of our energy with hydroelectric power. Investing in our hydroelectric dams makes good sense – some of them are more than 100 years old – and it’s a continual process.
You can sense a pride of ownership from the crew featured in the above video. Many of these employees, who worked to remove and replace the old turbine, have been working on hydroelectric generation projects for many years. When the Noxon Rapids work is complete, these employees will move onto other projects, but their legacy will live on in the additional energy they helped produce.
