Clean energy

Clean (carbon-neutral) energy comprises over 70% of Pacific Northwest energy resources. See this infographic for more.

Generating projects

  • Existing and new/proposed power plants
  • This combined spreadsheet now includes both existing projects, and new/proposed projects in the Northwest.
  • Includes projects under construction, permitted sites, proposals, recently-completed projects and recent retirements.
  • If you have updated project information, please email Gillian Charles.
  • Graphs below are based on this spreadsheet

Capacity is essentially the 'horsepower' rating of power plants, or how much they are designed to produce at full load operation

Capability is the maximum amount of energy the plants are capable of producing over the course of an average year

Total energy produced each year

Energy brought online or retired each year (new plant construction, etc.)
