Our Tradition

Our company was born in 1916, when five companies combined assets, including water rights and hydroelectric facilities on the Snake River, to form Idaho Power.

Those five companies were:

• Idaho-Oregon Light & Power
• Idaho Railway Light & Power
• Idaho Power & Light
• Great Shoshone and Twin Falls Water Power
• Southern Idaho Water Power

Harnessing The Power of Falling Water

The bulk of our generating ability comes from our 17 hydroelectric power plants. We are proud to be one of the nation's few investor-owned utilities with a significant hydroelectric generating base. During the 1940s, 50s and 60s, we built the majority of our hydroelectric facilities, culminating with the completion of the three-dam Hells Canyon Complex in 1968.

With headquarters in Boise, Idaho, and an employee base of approximately 2,000 people, Idaho Power is an electric utility engaged in the generation, transmission, distribution, sale and purchase of electric energy.

Our Energy Future

Population growth and increasing energy consumption continue to challenge utilities nationwide. In our service area, planners estimate adding thousands of new customers annually into the year 2020.

Since 1916 we've been here for you. Powering homes, schools and businesses, ensuring prosperity for our communities with reliable, low-cost electricity then and now.

Idaho Power must balance competing considerations to ensure comfort and security for today's customers, as well as tomorrow's.

Balancing the elements of our three-part strategy — responsible energy planning, responsible development and protection of resources, and responsible energy use — ensures we meet future challenges thoughtfully.

Our energy future and the future of our communities is dependent on the understanding, input and actions of each of us. Wise use of energy helps ensure reliability and keeps your monthly bill low.

In addition, every kilowatt saved is one we don't have to generate, reducing the number of additional new resources required and the need to purchase power on the open market, often at a premium.

Getting To Know Us

Idaho Power is an electric utility engaged in the generation, transmission, distribution, sale and purchase of electric energy and is regulated by the Federal Energy Regulatory Commission (FERC) and the state regulatory commissions of Idaho and Oregon. The company is involved in the following business activities:

• Generation — we rely on our 17 hydroelectric generating plants on the Snake River and its tributaries, natural gas-fired plants and shares of three jointly-owned coal-fired plants.
• Transmission — to get electricity generated at Hells Canyon, for example, to homes and businesses, it's first transmitted over long distances on transmission lines to substations.
• Distribution - distribution lines are smaller than transmission lines and are used to bring electricity from substations to homes and businesses.
• Sales — of electricity to retail (residential, business and irrigation) and wholesale (other utilities, energy marketing companies and incorporated municipalities) customers.
• Purchases — we purchase from the wholesale market when additional energy is needed to serve customer loads or when purchasing from the market is less costly than running our generating plants.

With 17 low-cost hydroelectric projects as the core of our generation portfolio, our residential, business and agricultural customers pay some of the nation's lowest prices for electricity.
