WIND
We've participated in wind technology research for more than 20 years. Our investment in wind power has helped bring the cost of production down for consumers. Here are some reasons why wind power is growing:

• With federal incentives, wind power ranges in price from 3 to 6 cents per kilowatt-hour, depending on transmission and other costs.
• Wind power produces no air emissions.
• Every kilowatt-hour of wind energy produced means one to two pounds of carbon dioxide emissions are not released by thermal plants.
• By adding more turbines, wind projects can also easily be expanded to help meet a utility s growing energy needs.

Currently, we purchase wind power from several facilities:

1. Marengo
This 140.4-megawatt project is under construction near Dayton, Washington. It is expected to be completed in August 2007. The project is being built on about 13,000 acres of agricultural land and will have a several hundred-million-dollar impact on the local tax base.

2. Leaning Juniper I
In July 2006, we purchased the Leaning Juniper 1 wind energy generation facility located about three miles southwest of Arlington, Oregon. The facility has a generating capability of 100.5 megawatts enough energy to serve more than 30,000 homes each month. The land is also used for wheat farming and grazing.

Turbines: 67, 1.5-MW General Electric turbines
Output: 100.5 MW

3. Wolverine Creek
We are purchasing the output of Wolverine Creek wind farm, a 64.5-megawatt generation facility located about 10 miles southeast of Idaho Falls, Idaho. The facility generates enough electricity to supply energy to about 19,000 homes. The project went on-line in December 2005.

Turbines: 43, 1.5-MW General Electric turbines
Output: 64.5 MW 

4. Eurus Combine Hills
The December 2003 startup of the Eurus Combine Hills 41-megawatt wind farm in Milton-Freewater, Oregon, was the culmination of an innovative collaboration between an independent nonprofit (the Energy Trust of Oregon), a wind developer (Eurus Energy America) and Rocky Mountain Power.

Turbines: 41, 1-MW Mitsubishi turbines
Output: 41 MW

5. Foote Creek Rim I
We co-own the Foote Creek Rim I in Wyoming. On the most blustery days, the facility is capable of generating enough to power about 20,000 homes. Compared to previous wind turbine technology, the project s use of large turbines means that fewer machines are needed to produce the same amount of energy. The land is also available for other uses, such as grazing livestock, because the facility only occupies about one percent of the land it is housed upon.

Turbines: 69, 450/600 turbines
Total output: 41.4 MW capacity

6. Rock River I
We are buying the entire output from Rock River I in Arlington, Wyoming. for the next 20 years. This is enough power to serve about out 13,000 homes.

Rock River fast facts
Turbines: Each of the project s 50 turbines is mounted on a 60-meter tall tubular tower and has rotors 57 feet in diameter.
Output: Rock River has an output of 50 megwatts. The turbines produce power at a wind speed of eight miles per hour (mph), reaching peak production at 17 to 20 mph, and shut down when winds reach 55 mph.

GEOTHERMAL
At our Blundell plant, the source of energy is ground water 3,000 feet below the Earth's surface. It contains water at more than 500°F and at a pressure of 500 pounds per square inch. Blundell is a fully renewable, zero-discharge facility. It was the first geothermal electric plant outside of California.

Generating capacity: 26.1 MW
Fuel: Steam

BIOMASS
We have signed and agreement with Evergreen BioPower for a new, 10-megawatt biomass generation facility located at Freres Lumber in Lyons, Oregon. It will begin providing reliable renewable energy to customers in late 2007. This facility will use residual waste wood that results from the lumber manufacturing process to generate steam for both the lumber drying process and to produce electricity.

ENERGY EFFICIENCY
We offer several programs and incentives to help residents and businesses save energy and money.

AIR QUALITY
We employ innovative air quality initiatives to reduce our environmental impact. Working together helps us strike a balance that protects the environment while allowing for the efficient use of coal resources to produce electricity. To this end, we are working to develop new clean coal technologies and to clean up our existing technologies. We also provide toxic release inventory standards to educate the public about releases in the environment.

We are addressing concerns about climate change by reducing our carbon dioxide emission rate through commitments to build additional renewable generation and new gas resources. We've also formed the Global Climate Change Working Group – composed of representatives from environmental, governmental, academic and industry groups – to study the development of climate science and its implications for teh electric needs of our customers. Involving many of the same groups, we have organized another working group to examine coal gasification and related technologies that could remove carbon dioxide from fossil fuel combustion.

ISO 14001 registration
More than 5,500 megawatts of Rocky Mountain Power's coal-fired generation – seven power plants in Utah and Wyoming – have earned the ISO 14001 registration for their environmental management systems.

ISO 14001 is an international, voluntary, environmental management standard. To receive ISO registration, each power plant must prove it has the necessary processes in place to understand its impact on the environment and the community, along with the methods to continuously improve its environmental performance.

GREENCORPS
Our GreenCorps program provides grants to employee projects focused on preserving, improving and encouraging education about the environment. Since 1993, we have provided more than $425,000 to more than 200 projects including planting trees and restoring stream beds.

HABITAT PROTECTION
As a responsible environmental steward, we collaborate with the public and resource agencies to identify sensitive species and their habitats and to implement management plans that promote their preservation. We have programs addressing wildlife protection, hydroelectric facilities impact on fish and relicensing, and bird interactions with power lines and wind turbines. We also reclaim land after completing our mining operations to restore habitat.

WASTE RECYCLING AND REUSE
We are dedicated to minimizing our environmental footprint through our waste reuse and recycling programs. Metals such as aluminum, copper and steel are recovered from most of our service locations. Many transformers and other electrical equipment are also repaired and sold for reuse. Select used oil is also reused in rebuilt equipment, while other oil from our vehicles and electrical equipment is recycled for energy recovery. Paper, cardboard, wood and plastic are also recycled where possible.
