Coyote Springs 2 images
Coyote Springs 2 is combined cycle generation plant that uses natural gas and steam

Avista’s generation unit at Coyote Springs has been disassembled since May 4 as major overhauls take place for the first time since the plant was built. The springtime timing is beneficial, since the maintenance requires the combined cycle plant to be offline during work.

Coyote Springs 2, near Boardman, Oregon is a combined cycle generation facility because it has a gas turbine that exhausts waste heat into a heat recovery steam generator, which provides steam to a steam turbine.  Each turbine has its own generator that sends the electricity produced to the generator step-up transformer.

Portland General Electric Company owns Unit 1 and oversees daily general operations and maintenance activities for both units. Avista owns Unit 2 and does special projects and major maintenance for Unit 2, including this one.

The project involves overhauling the natural gas and steam turbines in Unit 2 as part of scheduled major maintenance work, required at regular intervals in the plant’s life. Avista’s thermal engineering group is coordinating the project and some of the work is being performed by Avista’s mechanical structural crews. 

“This is the first time some parts of the steam turbine have been disassembled since it went in service on July 1, 2003,” Andy Vickers, Manager of Generation & Substation Support, said.

See photos of the dissassembled steam and natural gas unit in the slideshow above.

Reassembly is taking place over the next couple of weeks, and the unit is expected to be back online by the end of June.

Avista is working to improve paths and viewing points along the Spokane River

Riverfront Park footbridge
Pedestrians can still access the suspension bridge to
get some great views of the Spokane River, however
the south entrance of the bridge near the Upper Falls
powerhouse will be closed for construction.
New viewing platform on Spokane River
Later this summer, Riverfront Park visitors will also
have a new east-facing viewing platform to take in
the beautiful Spokane River.
Viewing area, looking east
The footbridge near the viewing platform will be open
to pedestrians during Memorial Day weekend.
Beginning this week, Riverfront Park visitors in downtown Spokane will be detoured away from the south end of the suspension bridge by Avista’s Upper Falls Dam powerhouse.

For the next four weeks, Avista is working on a project to improve the deteriorated asphalt roadway and powerhouse parking area. The asphalt roadway will be repaved with asphalt, concrete will be installed in front of the powerhouse, and reinforced turf and porous pavers and grass will be installed in this area. These improvements will improve access to the powerhouse and will make for an easier, safer trek for pedestrians crossing the bridge.

You can still enjoy the great views on the bridge by accessing it from the north side of Canada Island; you just can’t cross the bridge on the south end until the work is complete. The nearest river crossing in the park is Howard Street Bridge, just east of the suspension bridge by the Upper Falls Powerhouse. Signs will be posted to redirect park users.

Safety is a top priority at Avista. During our project, you may see workers, cranes, and other construction equipment in the area. For your safety, please obey posted signs and stay out of fenced-off areas.

New viewing platform
Later this summer, Riverfront Park visitors will also have a new east-facing viewing platform to take in the beautiful Spokane River. Avista constructed the viewing platform last fall so we could access the Upper Falls Dam for maintenance and upgrades. This spring, we’re working on the east end of Havermale Island to complete paving of the area. Spokane City Parks and Recreation will take it from there to put in plants and vegetation.

The footbridge near the viewing platform will be open to pedestrians during Memorial Day weekend.

The work we’re doing will improve pedestrian access and aesthetics at Riverfront Park.

Natural gas pipeline work in Davenport.
Natural gas pipeline work near Davenport
Avista is replacing nearly 9 miles of natural gas
pipeline in Davenport, Wash. The project is
estimated to cost more than $3 million. The
work will be conducted May to October.
Bring in the diggers and heavy equipment because construction is underway in Davenport, Wash., as Avista replaces nearly 9 miles of natural gas pipeline that’s approaching the end of its service life. The project carries a price tag of more than $3 million. It’s part of Avista’s commitment to maintain and upgrade our natural gas pipeline system.

From May through October, Avista-authorized contractor Loy Clark will be installing new natural gas pipelines in streets and alleys throughout Davenport.

As we replace the natural gas pipeline one section at a time, Davenport natural gas customers will experience a short interruption of service while we’re working on the natural gas pipeline in a specific area. Customers will be notified two days in advance of working in their neighborhood so they can plan ahead. Once the work is complete and service is restored, qualified Avista personnel or contractors will safely relight appliances, such as water heaters.

Attendance was light when we held an open house at the Davenport Memorial Hall on Wednesday, May 2, to answer questions about the project. Hopefully that means that folks in Davenport are comfortable with the project.

This six-month, $3 million project is just one example of how Avista must continually invest in maintaining and upgrading the natural gas pipelines that allow us to serve our customers.

Wind and solar get the renewable headlines, but what about biomass and hydro?

Post by Dan Kolbet

Renewable Energy
At Avista we like to say that we were founded on renewable hydroelectricity. We’re proud of it. Even today the biggest resource percentage of generated or purchased power comes from hydroelectricity. Yet nationally, renewable energy tends to be framed around wind, solar and sometimes biomass and hydro. Where does Avista, biomass, hydroelectricity and your power fit in the renewable discussion?

Let’s start with hydroelectricity. Unlike much of the country, the Northwest benefits from having abundant hydroelectric resources. It’s good for all of us, because it’s in our backyard. It’s pretty tough to get a new hydroelectric project started in the United States, so the growth in this area generally comes from modernizing generation to make it more efficient. For the past decade or more we’ve been doing just that on the Clark Fork River at our Noxon Rapids and Cabinet Gorge dams.

Some of our hydroelectric dams on the Spokane River are more than 100 years old, and since we need to keep those dams running responsibly and reliably, we’re always looking for ways to improve them. This year, we’re looking at upgrading parts of our Post Falls and Little Falls hydroelectric facilities. There’s no doubt about it, hydroelectricity is an important renewable resource.

Biomass is another example of renewable energy that doesn’t get much of the spotlight. Avista’s Kettle Falls biomass plant was the first electric generating station of its kind constructed within the United States for the sole purpose of producing electricity from wood waste. It opened in October of 1983 – roughly 29 year ago. That’s a long history of renewable generation. Beginning in 2016 Washington will officially recognize its operations as a renewable resource for the purposes of meeting Washington state Renewable Portfolio Standards (RPS).

Now for the hip, cool kids – wind and solar.

Solar panels
A small solar array is affixed to the top of our
corporate headquarters today. It helps offset the
power we use to charge the
Avista Sun Car.
Let’s talk solar first. Sure, the sun is free, but equipment involved in generating and delivering that power to the grid isn’t free - not by a long shot. In our area, given our other resources (like hydro), utility scale solar power isn’t in the cards, at least not today. We’re always on the lookout for proven resources, so that may change in the future, in fact a small solar array is affixed to the top of our corporate headquarters today. It helps offset the power we use to charge the Avista Sun Car.

Last, but certainly not least in this renewable roundup, is wind. Today Avista doesn’t generate any of its own power via wind, yet we’ve had a long-standing contract to buy wind power from the Stateline Wind Project on the Washington/Oregon border. Soon a new wind farm called Palouse Wind will come online near the town of Oakesdale and State Route 195 on the hills surrounding Naff Ridge. The project is being developed by First Wind, but Avista has secured the rights to its electrical output for next 30 years. Avista has been thinking about how to incorporate wind into our generation mix for several years, so it’s certainly on our minds.

As you can see, from hydro to biomass, and wind to (a little) solar, we’re all over this renewable thing.

For another look at Avista’s power generation and planning for the future, check out our Electric Integrated Resource Plan (IRP). The IRP analyzes and outlines a strategy to meet projected demand and renewable portfolio standards through energy efficiency and a careful mix of qualifying renewable and traditional energy resources

Renewable energy and you
Avista launched a Buck-A-Block voluntary rate program for customers in 2002. The program is still going strong today with thousands of megawatt hours of emission-free wind being purchased annually. Nearly 4,000 customers participate. When you sign up for Buck-A-Block, you make a voluntary payment above and beyond your normal rates. Avista makes no profit from that additional money, which goes to support the renewable energy many of our customers prefer by purchasing environmental offsets from renewable energy generation.

Four-year, $45 million upgrade nearing completion at Avista’s largest hydroelectric dam

Post by Brandi Smith
Noxon Rapids
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.

We need to invest about $250 million each year over the next five years to continue updating and maintaining our system to serve our customers’ energy needs

Noxon Rapids Unit 4 turbine
The new Noxon Rapids Dam Unit 4 turbine is
lowered into place earlier this year. This 4-year,
$45-million project is coming to a close in 2012.
Pole replacement
An employee works to replace old wooden poles
(left) with a new steel structure (right). Steel
structures are more expensive, but typically last
longer than wooden ones.
New power lines
A line crew runs a new, higher-gauge power lines
over a two block distance in downtown Spokane.
Work like this ensures a more reliable system
that’s ready when you need it.
Working safely
An employee wears protective gear while using a
grinder at a natural gas job site in Spokane
Valley. We do our best to work safely on the
system that delivers you energy. 
Today Avista filed requests with the Washington Utilities and Transportation Commission to increase overall net electric rates by 5.9 percent, and natural gas rates by 6.8 percent in Washington only. The UTC has up to 11 months to review the filings and issue a decision.
What does this mean to you? If you’re an Avista electric customer in Washington with average use and the Commission approves the requests, you would see an increase of $4.94 per month or about 16 cents a day, for a revised bill of $83.91. If you’re a natural gas customer in Washington with average use, you would see an increase of $4.23, or about 14 cents a day, for a revised monthly bill of $65.78.

So why is Avista asking for more rate increases? The simple answer is that it costs more each year to provide safe, reliable energy to you. Meeting our customers’ energy needs reliably and responsibly, while still complying with state and federal requirements, is our first obligation, even when it costs more.

About 40 percent of your electric bill and 35 percent of your natural gas bill covers the cost of delivery – the equipment and people needed to provide safe, reliable energy service to you. Maintaining and updating our generation plants (some that are more than 100 years old) and substations, along with more than 18,000 miles of power lines, a quarter of a million poles, and nearly 8,000 miles of gas pipeline, is a big job that doesn’t stop, and one that costs more each year. When we replace or update old equipment with new equipment and technology, it costs many times more than when it was installed. It’s much like when you update your older home or vehicle. Imagine replacing flooring, cabinets and appliances in a kitchen built 40 years ago, and how much more those items cost today than they did in the 1970s.

This was the primary reason for the proposed increase in our last request and we expect it to continue to cause a need for increased rates in the future. We’ll need to invest about $250 million each year over the next five years to continue updating and maintaining our system to serve our customers’ energy needs. And, while our customers still pay some of the lowest prices in the northwest, we’re not the only utility facing rising costs and an aging system.

Keeping rates increases as low as possible
Even so, we work hard to manage our own costs and keep rate increases as low as possible. In the filings, Avista proposed a proposed one-year Energy Recovery Mechanism bill decrease, which is a rebate to customers based on power supply costs, to help offset the increase. About 60 percent of a customer’s electric bill and 65 percent of a natural gas bill is the cost of generating or purchasing electricity and purchasing natural gas to meet customer needs. Power supply costs were lower in 2011, due to factors such as declining natural gas prices and favorable hydroelectric conditions.

We also proposed through this request to help ease the burden of the increase on low-income customers with increased funding for Avista’s energy assistance programs.

Don’t forget, Avista offers services for customers such as comfort level billing, payment arrangements and Customer Assistance Referral and Evaluation Services (CARES), which provides assistance to special-needs customers through referrals to area agencies and churches for help with housing, utilities, medical assistance and other needs.

Executive salaries in Wash. rates aren’t going up
So what about executive salaries, and how much do the salaries and incentives of our executive officers affect your rates? Not as much as you might think. Avista has proposed that the amount of executive officer salaries and incentives included in rates remain at their 2011 levels.

Approximately 25% of total officer salary and incentives is included in Washington retail rates, which makes up less than ½ a penny of every dollar you pay in rates. This adds up to about 40 cents of your monthly bill if you’re an electric customer with average use, and less than 75 cents if you get both electric and natural gas service. The bottom line is executive salaries aren’t driving energy costs up, rather it’s the rising costs of doing business and taking care of our system.

We realize in these difficult economic times it can be a struggle for people to pay their energy bills. We’ll keep working to reduce costs and improve efficiency while continuing to provide reliable, responsible energy at some of the lowest prices in the Northwest.

Avista worked with crews for Northern Pipeline to relocate almost 2,000 feet of six-inch high pressure main in White City, Oregon over the last month. Work like this helps create reliable service for Avista natural gas customers.
This particular project, which shows your rate dollars at work, is estimated to cost around $250,000. These photos show some of the progress happening in the shadow of Mt. McLoughlin.

New poles and electric lines assure an efficient electric delivery system

Reliability: Click to View Service Territory Map
As you head west on East Sprague Avenue in the Spokane Valley over the next two to three months, you may notice some construction activity with Avista Utilities trucks and crews working in the area.

In order to continue to serve you with safe, reliable electricity, we’re replacing two miles of old wooden poles with new ones. We are also replacing old, smaller wire with larger wire, which increases the efficiency of our delivery of energy to your homes and businesses. The power lines we are working on provide electricity to the entire Sprague/Appleway corridor and the adjacent areas.

The cost of delivering safe, reliable energy includes maintaining a huge system of pipes, poles, generation facilities and substations. Many parts of our system are 30, 40 and even 50 years old.

What you are witnessing in Spokane Valley and throughout our service territory are your rate dollars at work to provide safe and reliable service.

Upgrades to our infrastructure, such as this two-mile pole and wire replacement project, make up around 40 percent of your bill – the cost of delivering energy, serving our customers and energy conservation. The other 60 percent is the cost of the energy itself – the cost of generating or purchasing electricity.

So the next time you see projects like the one on Sprague, you’ll get a up close and personal view of the kind of work we do all the time to make sure you have safe, reliable and efficient energy to your home or business.

For more stories about reliability, renewable energy, the environment, community, rates and more, visit us here at the Avista Blog often.

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.
