Environmental Commitment

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​An Environmental Stewardship Program (ESP) is a systematic approach to managing environmental hazards and potential impacts. It helps us identify potential environmental risks and prevent negative impacts by putting necessary controls and programs in place, monitoring and measuring environmental performance, continually improving and sharing our progress with interested parties. The ESP reduces risk while improving efficiency and effectiveness.

For more than 60 years, Energy Northwest has produced carbon-free energy – first through hydroelectric power, later by adding nuclear, wind and solar. Utilizing clean energy is important to ratepayers throughout the Northwest and vital to protecting the environment for current and future generations.

As an organization, Energy Northwest is committed to doing its part to take care of the environment. The ESP underscores Energy Northwest’s commitment to the environment.
