Portland General Electric Co. (PGE) opened the Trojan Nuclear Plant in 1976.

Officials at Trojan faced high operating costs, coupled with a $200 million repair bill to replace four steam generators. The abundance of cheap hydropower in the Northwest and cheap natural gas from Canada led PGE's board of directors at an August, 1992, meeting to decide that "phasing out" the Trojan plant over four years would be cheaper than trying to run the plant until its license expired in 2011. The decision was based purely on economics, not because of safety concerns. The plant was closed in 1993.

The large component removal project (LCRP) at Trojan, from November 1994 to November 1995, included the removal and shipment of the Trojan steam generators and pressurizer to the U.S. Ecology low-level waste repository at Hanford, Washington. Plans are under way by PGE to ship the reactor vessel from the closed Trojan nuclear power plant with its irradiated internals intact in August 1999. It will be shipped by by barge up the Columbia River to the Port of Benton, Washington, and from there, by heavy-haul transporter, to U.S. Ecology's Low-Level Radioactive Waste Disposal Facility near Richland, Washington for burial. PGE plans to begin operating an independent spent fuel storage installation (ISFSI) at Trojan in April 1999.
