Our Energy Future

Managing Our Energy Sources
Our Energy Future

A diverse energy portfolio is like a diverse retirement portfolio: The ups and downs in weather and prices have less of an impact on rates. It’s also easier to manage supply and demand when there’s a set supply of “firm,” or predictable power.

Diversity = stability, for both prices and power production. Our hydroelectric and thermal base provides a steady, firm flow of power. This allows us to integrate sporadic resources like wind and solar. Our customers benefit from a varied generation portfolio.

Since 2009, we have voluntarily reduced our company’s carbon output per megawatt below 2005 levels. We are among the lowest carbon-emitting utilities in the country. We will continue to responsibly reduce our carbon footprint.

Hydro Power

In above-average water years, Idaho Power's 17 hydroelectric (hydro) facilities are our largest energy source, providing more than 50 percent of the energy delivered to customers.

One of our main goals is to protect and, when prudent, augment these clean, emission-free hydro resources. This allows us to keep our customers’ rates among the lowest in the nation.

Renewable Energy Sources

We have a long history of supporting and developing renewable energy.

We have signed contracts for 461 megawatts (MW) of solar power and more are expected.

Our hydroelectric system is the core of our generation fleet. We have 17 hydro projects on the Snake River and its tributaries. These produce more than half the electricity used by our customers in a normal year.

We initiated the first major wind project on our system, the 101-MW Elkhorn Valley Wind Farm in eastern Oregon.

We have power purchase agreements with two geothermal plants.

Other Generation

We are on a glide path away from coal as a resource and toward cleaner natural gas and other alternative resources. In addition to construction of the Danskin and Bennett Mountain natural gas-fired power plants in Elmore County, we built the Langley Gulch Power Plant to serve as a flexible resource to meet projected energy demands.

Our forecast of customer demand doesn’t show a need for additional generation until 2021, beyond that our proposed Boardman to Hemingway transmission line will allow us greater access to the energy market without building new power plants for the foreseeable future.


Producing energy is only one part of the equation. It must be delivered to our customers. Our existing transmission system sometimes limits our ability to import and export electricity or to move it within our system. That’s why we focus on three important areas necessary to maintain reliable service:

We are considering all alternatives. Increasing transmission capacity improves reliability. It also allows us to serve customer demand in the most cost-effective manner.

A robust transmission system also helps us add new alternative resources and enhance our region's economy. Learn more about what we're doing to develop high-capacity transmission line projects:
