GORGE Boardman Coal Plant closes.jpg

The Boardman Generating Station, above, has been shut down. The plant was Oregon’s only coal-powered electricity generating plant. According to Portland General Electric Company, which owns the plant, the early shutdown is “a major step on our path to meeting Oregon’s greenhouse gas emissions reduction goals and transforming our system to reliably serve our customers with a cleaner, more sustainable energy mix.”

Portland General Electric Company announced Oct. 17 it has permanently shuttered its Boardman Generating Station in Eastern Oregon’s Morrow County. The closure fulfills an agreement PGE reached with stakeholders, customer groups and regulators in 2010 to significantly reduce air emissions from power production in Oregon by ending operations at Boardman 20 years ahead of schedule and transitioning to cleaner energy resources. Boardman is the only coal-fired power plant in Oregon. PGE has a 90 percent ownership share of the plant. Idaho Power owns the remaining 10 percent.

While the plant was operating, air quality studies in the Columbia River Gorge by the Oregon Department of Environmental Quality found the plant contributed to poor air quality in the region during certain atmospheric conditions.
