PGE Boardman

Portland General Electric Company, also known as PGE, operates several natural gas-fired electric generating plants in Oregon, including two near Boardman:

  • The Carty Plant is a 440-megawatt plant located on Tower Road about 10 miles south of Boardman. The adjacent Boardman coal-fired plant closed in October 2020.
  • The Coyote Springs Plant is a 249-megawatt plant located at the Port of Morrow in Boardman. 


DEQ seeks comments on proposed air quality permit modification for PGE Carty 

DEQ accepted comments on a proposed modification to an existing air quality permit for the PGE Carty electricity generation facility near Boardman. Comments were due at 5 p.m. on Friday, Dec. 17, 2021.

The permit modification is needed for two reasons: because PGE's coal-fired power plant closed in October 2020 and because the manufacturer of the PGE Carty plant's natural gas turbine released new information that startup and shutdown emissions for two pollutants, carbon monoxide and volatile organic compounds, are higher than originally estimated. PGE starts up and shuts down the turbine to meet the electricity needs of the communities it serves. Electricity needs fluctuate due to electricity use and contributions from other power sources.  

The proposed permit modification does not change how much natural gas PGE Carty uses or change the hours the plant can run. The modification proposes to remove emissions allotted for operation of the coal boiler and incorporate the new manufacturer information for natural gas turbine start-up emissions. This will result in a reduction in most emissions limits and an increase in the limit for volatile organic compounds. 

Public hearing

DEQ hosted a public hearing on Nov. 9, 2021 to provide information and accept verbal comments on the proposed permit modification.
