So, there's a gas decrease request and a request for an increase and a . . . well, it's confusing at times. Let us explain.
Question for the day: Have you ever thought about what makes up your natural gas bill?
Other than looking at how much our monthly bill is and maybe how much energy we used the last month, most of us don’t give it a thought.
As an Avista customer, every dollar you pay for natural gas service on average is made up of three different components – the wholesale cost of the natural gas used (41 cents), the cost for transporting that gas from the producer to Avista’s distribution system (13 cents), and the cost for the people, equipment and services needed to deliver that gas to your home (46 cents).
Last Thursday, we asked the Washington Utilities and Transportation Commission (UTC) to allow Avista to decrease natural gas rates for the second time this year by an additional overall 4.4 percent because wholesale natural gas prices continue to decline. You can read more about the request in the news release
If our request is approved by the UTC, the new lower rates would be effective Nov. 1, making Washington residential natural gas rates over 11 percent lower than at the beginning of this year. This requested decrease is in the wholesale cost of gas (41 cents) and fixed transportation (13 cents) portions of your bill.
If you’re a Washington customer, you may have seen an insert in your August energy bill that provides information on a different Avista rate request
called a general rate case. That request was made last April to increase both electric and natural gas rates. So, why are we asking to decrease and increase natural gas rates at the same time?
The natural gas portion of the general rate case is for the delivery portion (46 cents) of your bill – the people, equipment and services needed to safely and reliably deliver natural gas to you. The request to increase natural gas rates by an overall 5.9 percent is to recover increasing costs to operate and maintain the natural gas system. The UTC has up to 11 months from when the request was made to review and issue a decision.
Rates are complex and can be confusing, so we have a short video that gives more information
on the general rate case process. Information on Avista’s general rate case, including upcoming public hearings, is available in the Notice of Request for Rate Increase brochure that was in your August Avista bill. If you missed the insert click this link

If approved, new rates would go down 4.4 percent – or 11 percent when combined with March decrease
Good news if you’re a natural gas customer in Washington – your rates could go down for the second time this year thanks to lower wholesale natural gas prices.
We filed a request today asking to reduce natural gas rates in Washington by an overall 4.4 percent. That’s in addition to a 6.4 decrease that was effective March 1 of this year. If the Washington Utilities and Transportation Commission approves our latest request, beginning Nov. 1 residential rates would be over 11 percent lower than at the beginning of this year. You can read more about our request and the drivers in today’s news release

When you think about how your electricity is generated you probably think it comes mainly from hydropower
. But did you know that Avista also uses natural gas as a fuel to generate electricity? In fact, it makes up 36% of our company owned electric power plants
. Natural gas generation is a dependable source of energy because the fuel can be stored to generate electricity anytime, and it has about half the carbon emissions of other fossil fuels, such as coal.
Avista and Portland General Electric co-own a combined cycle natural gas plant called Coyote Springs, located in Boardman, Oregon. The plant has 2 main generation units, and Avista owns Unit 2.
A combined cycle plant has a gas turbine and a steam unit all in one. These types of units are considered very efficient because they use the waste heat from the gas turbine to create steam, instead of exhausting it back into the atmosphere.
Unlike a simple cycle gas plant, which can be fired up quickly to meet the electricity generation needs of customers, the combined cycle plant at Coyote Springs is considered a “base load” facility because the natural gas generator needs to run consistently in order to provide heat for the steam generator.
Like a car, there are certain maintenance activities that need to take place after a number of years. This year, unit 2 had its first scheduled major maintenance since the unit went in service in 2002.
The project involves overhauling the natural gas and steam generators in unit 2. From start to finish, the project takes approximately six weeks to complete and a great deal of collaboration and teamwork.
The end result of the maintenance is that Unit 2 at Coyote Springs will continue to have the capacity to generate an average of 280 megawatts of power for our customers – that’s enough electricity for just over 210,000 homes.

It takes a village to get natural gas delivered to your home safely, reliably and affordably
In our previous articles, Natural Gas Pricing 101, Part 1
and Part 2
, we explained that more than half of a customer's monthly natural gas bill is the cost of the natural gas we purchase on the wholesale natural gas market and the transportation costs to get that natural gas to our system. The remaining portion of the bill, about 45 percent – or 45 cents of every dollar a customer pays for natural gas – covers our costs of delivering natural gas to a home or business.
If you’re a Washington natural gas customer, your
rates are at levels similar to those from 2003. (click
on image above and below to enlarge)
Did you know our customers are paying less today for natural gas than they were 10 years ago when you adjust for inflation? This is mostly because of the declining prices of natural gas on the wholesale market. As the chart shows, if you’re a Washington natural gas customer, your rates are at levels similar to those from 2003. When adjusted for inflation, natural gas rates in both Idaho and Washington have stayed fairly level over the past 50 years.
How do rising delivery costs impact your natural gas bill?
Avista takes the responsibility of maintaining and updating our natural gas delivery system seriously. We have an obligation to serve every customer who requests service and to comply with state and federal requirements. Safety and reliability are paramount to our operations.
Just like upgrading or replacing items in your own home, when we replace or upgrade older equipment, the cost of that equipment is many times more expensive than when it was originally installed. Capital investments like these, which are required to ensure the ongoing delivery of natural gas, along with rising operations and maintenance costs, continue to drive the need for increased rates. For instance, we’re working to replace miles of natural gas pipeline that has reached the end of its service life. The six-month, $3 million project in Davenport, Wash. is just one example of our commitment to maintain and upgrade our natural gas pipeline.
We file requests to recover these costs through our general rate cases, like the one we made to the Washington State Utilities and Transportation Commission in April of 2012. State regulators provide Avista the opportunity to earn a fair return, or profit, on the investment our shareholders have made in the facilities used to provide service to customers. The key word there is “fair,” and here’s how it works: When our costs change, Avista files a request with the state regulatory commission for a rate change. The commission scrutinizes every detail of our costs, reviews volumes of data and takes public testimony. Based on its investigation, the commission sets rates it believes serve the public interest – rates that are reasonable and fair for customers, while allowing Avista the opportunity to be a viable, healthy business and earn a fair return for shareholders, and enabling us to continue delivering safe, reliable energy.
In our last article,
we mentioned Purchased Gas Adjustment (PGA) filings. PGA filings are usually separate from general rate requests, and there are times when one of our state commissions may be reviewing a PGA request to decrease rates based on wholesale natural gas costs, while at the same time reviewing a general rate request to increase rates based on rising capital costs. Since we serve electric and natural gas customers in three different states it can be confusing for our customers to keep track of rate filings and rate changes. But as a regulated, investor-owned utility, we have to comply with the regulations set by the utility commissions in the three states where we serve customers, and we can’t increase or decrease rates without receiving approval from the commissions.
Here’s the bottom line: while the wholesale price of natural gas has declined over the past few years, the cost of delivering that natural gas continues to rise, and natural gas rates include both of these costs. Avista works hard to manage costs, improve efficiency and productivity, and be smart about how we purchase natural gas. We take pride in maintaining a system that keeps natural gas safe, reliable and as low-cost as possible.

How does Avista pass the costs of natural gas through to you? (Hint: we don’t mark it up!)
Click on the above image to enlarge the breakdown
example of a customer's natural gas bill.
You may have heard some good news
Avista shared last week with our Idaho customers. We filed requests with the Idaho Public Utilities Commission to decrease natural gas and electric prices. If the request is approved, this will be the second natural gas price reduction this year in Idaho and natural gas rates will have decreased by more than 14 percent overall in 2012.
If you’re an Avista natural gas customer, you have some of the lowest natural gas rates in the Northwest, and the wholesale natural gas costs in your bill have also dropped significantly in recent years. In fact, through rate decreases proposed by Avista and approved by state regulators, Avista customers have seen the wholesale price of natural gas decrease by almost 50 percent since 2008.
But a 50 percent drop in wholesale prices doesn’t equate to a 50 percent reduction in your natural gas bill, because the rates you pay cover much more than just the wholesale cost of natural gas itself.
In our article last week,”Natural Gas Pricing 101, Part 1: Natural Gas Supply,”
we explained how the combined costs of purchasing natural gas on the wholesale market and having it transported to our distribution system for delivery to you is about 55 percent of your natural gas bill – or 55 cents of every dollar you pay for natural gas. We work hard to keep these costs as stable and low as possible.
Avista customer's have seen the wholesale price of
natural gas decrease by almost 50 percent since 2008.
Let’s break that 55 percent down even further. The wholesale cost of the natural gas itself is about 38 percent of your natural gas bill. Avista does not make a profit on the cost of natural gas that is purchased to meet customer needs. You pay what we pay. Another 17 percent of your natural gas bill is the costs of transporting the natural gas on pipelines from the source or supply basins to our distribution system for delivery to you. While we also don’t mark up or make a profit on transportation costs, they are fixed, and have not declined like the cost of the gas itself has in recent years.
The remaining portion of your bill, about 45 percent, covers the cost of the equipment and people it takes to safely and reliably deliver natural gas through our distribution system to your home or business. State regulators provide Avista the opportunity to earn a fair return, or profit, on the investment our shareholders have made in the facilities used to provide service to you, and we’ll talk more about that in our next article.
What exactly is a Purchased Gas Adjustment (PGA)?
So how do we pass wholesale natural gas and transportation costs through to you, whether it’s increases or decreases in wholesale prices, or changing transportation costs? We call it a Purchased Gas Cost Adjustment, or PGA.
Our customers love the benefits they get from natural gas, but they don’t want surprises, especially in their energy bills. Imagine if your natural gas prices fluctuated like gasoline prices do. You might see your natural gas rates rise and fall several times in a month.
To keep this from happening, once each year Avista requests an adjustment in the natural gas rates our customers pay, to reflect our actual costs of purchasing natural gas on the wholesale market and transporting it to our system for delivery. These PGA requests to the utility commissions in Washington, Idaho and Oregon are usually made annually in August or September, and the new rates take effect by winter. Additionally, when wholesale prices of natural gas change significantly, we can make requests at other times of the year.
When costs are down, it’s good news for our customers, and we want to pass these price decreases on as quickly as we can. So far in 2012, Avista has filed out-of-cycle PGA requests
with the utility commissions in Washington and Idaho, as well as our regular annual request in Idaho
to reduce natural gas prices. Decreases took effect March 1 for our first requests, and, if approved, a second decrease for Idaho customers will take effect Oct. 1.
In fact, since 2009, Avista has filed 20 PGA requests for our customers; seven in Washington, nine in Idaho and four in Oregon – of those, 14 were to reduce gas prices based on declining wholesale natural gas costs. We expect to file our regular annual PGA requests in Washington and Oregon in the coming months. These changes in natural gas costs and the PGA rate adjustments do not increase or decrease Avista’s earnings and must be approved by state regulatory commissions.
Electric customers benefit
Coyote Springs 2, pictured above, is a natural gas
fired plant that generates electricity for customers.
The declining cost of natural gas also benefits electric customers through lower overall power supply costs. When it costs Avista less to purchase the natural gas we use to fuel our natural gas-fired generation plants, we can pass those savings onto you as well. In the general rate request we filed in Washington state
in April, due in part to declining natural gas prices, we proposed a one-year Energy Recovery Mechanism rebate to reflect the overall decrease in costs to generate electricity for Washington customers. Also, as part of our Idaho requests last week, we proposed a Power Cost Adjustment reduction
for our Idaho customers.
So whether you are an electric or natural gas customer of Avista (or both), you’re seeing the benefits of natural gas abundance and low prices, and you have been for some time. But what does it take to deliver natural gas to your home and provide the service to keep it safe and reliable, and how are the costs of the “the pipes and people” it takes to do that reflected in your natural gas rates? We’ll talk more about that in our next article, “Natural Gas Pricing 101, Part 3: Natural Gas Delivery and Your Bill."
Jul 31 , 2012
Today Avista filed several requests with the Idaho Public Utilities Commission to decrease natural gas and electric prices for our customers in Idaho. If approved, natural gas prices would decrease by an overall 8 percent and electric prices by an overall 2 percent for our Idaho customers beginning Oct. 1. This would be the second natural gas price reduction for our customers in Idaho this year. Read more about these filings in the press release we just issued
Each year, we propose to adjust rates our customers pay so that customers’ bills reflect our actual costs of purchasing natural gas and generating and purchasing electric power. Today’s requested rate reductions are due to, among other things, lower natural gas prices and lower power supply costs, which is good news for our customers. Learn more about Natural gas prices.
You may recall the commission in Idaho approved our request to reduce natural gas rates by an overall 6 percent in March. If today’s requests are approved, natural gas rates will have decreased by more than 14 percent overall for Idaho customers in 2012.
Today’s requests include two electric rate adjustments and two natural gas rate adjustments:
• Avista’s annual Power Cost Adjustment (PCA)
• Avista’s annual Purchased Gas Cost Adjustment (PGA)
• Electric and Natural Gas Energy Efficiency Tariff Rider Adjustments (Tariff Rider)
Post Falls Dam - a hydroelectric
facility in Idaho.
The major portion of an Avista electric customer’s bill, about 60 percent, is the cost of generating or purchasing electricity to meet customer needs. These costs may fluctuate up or down. The proposed PCA rebate would pass through reduced power supply costs during the twelve-month period that ended June 30, 2012.
We also filed a request with the IPUC to reduce the electric Energy Efficiency Tariff Rider Adjustment (Tariff Rider). The Tariff Rider is the rate paid by customers that funds the company’s energy efficiency programs.
The two proposed rate decreases will be offset partially by the expiration of an existing refund rate being passed through to customers.
If today’s requests are approved by the commission, the monthly bill for a residential electric customer in Idaho using an average of 939 kilowatt-hours per month would decrease from $80.55 to $79.46, a decrease of $1.09 per month, or 1.4 percent, beginning Oct. 1.

The combined costs of purchasing natural gas on the wholesale market and transporting it to Avista’s system makes up about 55 percent of an Avista natural gas customer’s bill, and these costs fluctuate up and down based on market prices. Avista does not mark these costs up. Read more about this in our Avista Blog series Natural Gas Pricing 101, Part 1: Wholesale Prices.
The annual Purchased Gas Cost Adjustment (PGA) is a true-up that balances the cost of wholesale natural gas purchased by Avista to serve customers with the amount already included in customer rates. Abundant supplies of natural gas and continued soft demand for the commodity have continued to keep wholesale natural gas prices at lower levels over the past year.
Our second natural gas rate request filed with the IPUC is to reduce the natural gas Energy Efficiency Tariff Rider Adjustment (Tariff Rider). Similar to the electric Tariff Rider for energy efficiency, the natural gas Tariff Rider is the rate paid by customers that funds the Company’s natural gas energy efficiency programs.
If our requests are approved, residential natural gas customers using an average of 60 therms a month would see a $4.42, or 7.9 percent, decrease in their monthly rate for a revised monthly bill of $51.36, beginning Oct. 1.

Avista customers see benefits of natural gas abundance
You’ve probably seen the headlines: “Natural gas prices fall to 10-year low,” or “Natural gas prices continue to drop.” But are these headlines really telling the whole story, and what do they mean to you as a natural gas customer of Avista? We’ve been talking about natural gas as a cleaner, more efficient and reliable source of energy for a long time now, but what about the economics of natural gas? How do new sources of natural gas affect wholesale costs, and how does that translate to your energy bill?
The good news is if you are an Avista customer, you have been seeing the benefits of increased natural gas supply and lower prices for some time. Through rate decreases proposed by Avista and approved by state regulators, Avista customers have seen the wholesale price of natural gas decrease by more than 48 percent since 2008.
But the relationship between headline-making wholesale prices and what you see on your bill each month is not always that clear cut. Over the next few weeks through this natural gas pricing series, we’ll discuss the cost components that make up a customer’s natural gas bill and try to clear it up a bit.
Natural gas bills include wholesale gas costs, interstate pipeline transportation costs and costs for equipment and people to get the natural gas to the customer
|There are three main drivers of your natural gas
energy bill: Whole sale gas costs; fixed
transportation costs; equipment and people.
Click to see the full chart.
There are three main drivers of your natural gas energy bill:
1. The cost of purchasing natural gas on the wholesale market is about 38 cents of every dollar you pay for natural gas. This cost is passed through to you without any mark-up or profit to Avista.
2. The cost to transport the natural gas on pipelines from the source or supply basins to Avista’s system is about 17 cents of every dollar you pay for natural gas. This cost is also passed through without any mark-up or profit to Avista.
3. The cost of the equipment and people it takes to safely and reliably deliver natural gas through our distribution system to your home or business is about 45 cents of every dollar you pay for natural gas. State regulators provide Avista the opportunity to earn a fair return, or profit, on the investment our shareholders have made in the facilities used to provide service to you.
You probably don’t think much about it when your gas furnace kicks on, or when you turn on your gas stove or use water that is heated with natural gas. But, like electricity, it’s taken a journey to get to you. Before we can deliver it to your home, Avista has to first purchase the natural gas and have it transported through large pipelines over long distances to our delivery system. The combined costs of purchasing and transporting natural gas to our system for delivery to you make up more than half of your natural gas bill. Avista doesn’t mark up these costs or make any money on this – customers pay what we pay.
When we purchase natural gas from the wholesale market, our goal is to secure reliable gas supply at the lowest cost so we can keep your costs as stable and low as possible.
Natural gas – grown at home
Natural gas is an abundant resource found throughout the United States and Canada. Since 2007, domestic natural gas production has increased, primarily due to the advances in natural gas drilling that have allowed production from previously untapped shale gas formations
throughout North America. The Energy Information Administration
now estimates that at today’s consumption levels there is enough natural gas to last the United States almost 100 years.
Avista is fortunate to be located near two prolific natural gas supply basins; the Western Canadian Sedimentary Basin, primarily located in Alberta and British Columbia, and the Rocky Mountain basin in Wyoming, Utah and Colorado. Not only is the North American natural gas resource base vast, the American Gas Association
describes it as “a home‐grown North American fuel whose efficient use by power plants, homes and businesses contributes to cleaner air.” Beyond the comfort and warmth it brings to our homes, natural gas is also recognized for its environmental attributes and contribution to American energy independence.
Wholesale prices are market driven

natural gas prices have been volatile,
at times increasing sharply and then
dropping just as sharply.
Click to see full chart.
Natural gas is a commodity. Ultimately the cost is set by the market. As in most free markets, natural gas prices are primarily influenced by supply and demand. Over the past decade, wholesale natural gas prices have been volatile, at times increasing sharply and then dropping just as sharply. Factors that have contributed to the volatility of natural gas prices including supply, demand, severe weather events like Hurricanes Katrina and Rita in 2005, and access to shale natural gas supply.
Avista’s purchasing plans provide more stability and help keep costs low
Avista wants what our customers want: an adequate supply of natural gas at affordable prices. Our goal is to strike a balance of ensuring reliable supply at competitive prices for our customers, and stabilizing natural gas prices so our customers see fewer fluctuations in their energy bills. Our employees in natural gas purchasing work every day to do this in several ways:
• We purchase natural gas from the supply basins mentioned above. These purchases are a mix of fixed price long-term, medium-term, and near-term purchases, which allow us to lock in prices for the future, and purchases on the short term market (also called the “cash” or “spot” market).
• We secure capacity rights on six large pipelines to assure delivery of supply from the supply basins to Avista’s distribution system.
• We’re part owner of Jackson Prairie, an underground storage facility in Washington State, so we can purchase natural gas and store it until we need it. We often purchase natural gas during warm‐weather months, when it traditionally costs less, and store it for delivery to our customers for use on those cold winter days.
Our natural gas purchasing plans are reviewed and revised annually to reflect evolving market conditions. Sound purchasing practices and decades of experience have helped us keep costs lower and more stable for our customers. In fact, Avista is paying some of the lowest wholesale natural gas prices among our utility peers in the region. It means our customers have some of the lowest natural gas rates in the northwest.
We’re also thinking ahead. Periodically Avista updates our 20-year outlook, which looks at how we can meet our customers’ natural gas needs over the long term, in a reliable manner at the lowest cost. We call this our Integrated Resource Plan.
We updated it in 2009, and we are currently in the process of completing our 2012 plan, which will be available at the end of the year.
As we mentioned earlier in the article, the combined costs of purchasing and transporting natural gas to our system for delivery to you can be more than half of your natural gas bill. These costs can also affect your electric bill. In our next article, “Natural Gas Pricing 101, Part 2: Natural Gas Supply and Your Bill,” we’ll explain more about how, with approval by state regulators, we pass these costs directly through to customers.
Later, we’ll discuss the remaining portion of your natural gas bill. “Natural Gas Pricing 101, Part 3: Natural Gas Delivery and Your Bill” will explain how your energy rates are also driven by the rising costs of the equipment and people it takes to get natural gas to your home safely and reliably.

The Burke-Thompson Falls A and B trans-
mission structures were originally constructed
in 1924. Avista crews are replacing the old

Avista upgrades nearly 90-year old equipment to improve safety and reliability
At the east end of the Silver Valley stands the Burke-Thompson Falls A and B transmission lines. Our customers in this region depend on these primary “arteries” of power to deliver electricity to their homes and businesses.
Situated in a remote location near the Idaho/Montana border, maintaining the Burke-Thompson Falls lines carries its own set of challenges. And part of the solution is rebuilding 8-miles of lines to better serve our customers.
The rural reality
The Silver Valley is known for its beautiful forests and ample snow in the winter. The rural reality – lots of snow and trees don’t bode well for transmission lines.
“The snow levels can get very high in that area,” said Kellogg Operations Manager Bob Beitz. “When outages occur in the winter, we can't access them without a Sno-Cat. When our crews jump out of the cat, they are up to their armpits in snow. Trying to replace a pole in those conditions is a herculean effort.”
All that snow can weigh heavily on the forested areas near the power lines, which can result in falling branches and toppling trees. Even if our rights of way are 100-feet wide, falling trees can cause power outages.
The solution: A rebuild to alleviate outages and concerns
This year, we’re rebuilding 8 miles of electric transmission lines from Burke to the Montana border to improve the safety and reliability of delivering power to our customers. The project carries a price tag of $2.5 million. It’s part of Avista’s ongoing investments to maintain and upgrade our electric system.
The transmission lines were originally constructed in 1924. Though updated several times over the decades, many of the original structures still exist and will be replaced this year. We’ll be re-using the existing wire for the project.
Avista crews are replacing the old wooden poles with taller, steel poles. The new design will stage the poles closer to the center of the right of way, which will improve efficiency, as the likelihood of a tree falling on the line diminishes. The new design requires 50 percent fewer poles as well.
Investing in the future
Many parts of our system are 30, 40 and even 50 years old. Some of the poles on the Burke-Thompson Falls A and B lines are nearly 90 years old.
As we rebuild this section of our electric transmission system, we’ll also have to build three temporary bridges to accommodate the heavy equipment necessary for the construction project.
It’s a big job, but it’s well worth the effort. This is another example of what it takes to provide safe, reliable service for our customers, now – and in the future.

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.

Customers continue benefiting from rebate and incentive programs to reduce energy use
Post by Anna Scarlett
Avista customers in Washington could see a decrease in their electric and natural gas rates beginning Aug. 1, if the Washington Utilities and Transportation Commission approves the company’s request to reduce surcharges that fund the company’s electric and natural gas energy efficiency programs.
The decreases are being requested to balance the amount of funding required for Avista to operate its energy efficiency programs, including the rebates and incentives paid to participating customers for installing energy saving measures. The requests are a part of Avista’s annual report to Washington regulators regarding the funding of the company’s energy efficiency programs.
If Avista’s requests are approved, electric customers in Washington would see an overall 1.9 percent decrease, or $1.47 a month for residential customers using an average of 989 kilowatt hours. Natural gas customers in Washington would see an overall 1.3 percent decrease, or a 79-cent per month reduction for residential customers using 68 therms. These tariff adjustments have no impact on company earnings.
Last year customers in Avista’s three-state service area received more than 43,000 rebates and incentives totaling almost $16 million. The energy savings are enough to power more than 5,300 Inland Northwest homes for a year and serve 2,300 homes with natural gas for a year, or almost 64,000 megawatt hours and 1.7 million therms of natural gas.
Of the rebates paid in 2011, more than 28,000 were to Washington customers totaling $11.4 million, more than 12,000 rebates to Idaho customers totaling $3.7 million, and Oregon customers received 2,300 rebates totaling $1.2 million. The most popular energy and cost-saving measures for residential customers included purchasing Energy Star ® appliances, installing high efficiency natural gas furnaces, and upgrading insulation. The average residential rebate for single family homes was $105.
Approximately $1.7 million was provided for weatherization for qualifying low-income customers in Washington and $595,000 for Idaho customers. An additional $40,000 was provided for conservation education for Idaho customers.
Information on energy efficiency rebates and incentives Avista offers for residential, commercial and low-income customers is available at www.everylittlebit.com, along with other energy-saving information.
