Noxon Rapids upgrades – your energy dollars at work

Crews reflect on work while installing finishing touches on four-year, $45 million project

Post by Anna Scarlett, Video by Dan Kolbet
Autographing turbine
An Avista employee signs Unit 4’s new turbine with
a paint pen prior to its insertion at Noxon Rapids
Dam. They don’t usually autograph their work in this
way, but the project has lasted four years and this
was the last new turbine installed at Noxon, so the
crew wanted to mark the occasion.
It’s a complicated job to turn water, wind, natural gas, coal, or even sunshine into reliable energy. It takes a lot of people and equipment and it doesn’t come free. In fact, about 60 cents of every dollar you pay each month in your electric bill is simply the cost of power, whether it’s power Avista generates at our plants or power we buy on the market.

Avista continues to generate or purchase about half of our energy with hydroelectric power, one of the cleanest, most dependable and most cost-effective energy resources. Investing in our hydroelectric dams makes good sense – some of them are more than 100 years old – and it’s a continual process.

In the case of Noxon Rapids, Avista’s largest hydroelectric dam, in 2012 we’ll be wrapping up our four-year, $45 million project to upgrade all four original generating units, which were installed in the late 1950s, with new turbines. The result? We can make more energy 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.

The new turbines boast features such as smooth edges and corners and a stainless steel body that weighs just 65 tons (as opposed to the old turbines, massive beasts that weighed around 120 tons.) Removing the old turbines and installing the new ones took thousands of hours of skilled labor and craftsmanship, and many of the crew members have been involved throughout the entire project. Watch the final turbine being installed at Noxon Rapids, and hear from some of the folks that helped make it happen. These are your energy dollars at work.
Watch an interview with project engineer P.J. Henscheid as the old Unit 4 turbine is removed back in fall 2011.
