Puget Sound Sound Power (PSP) said on Wednesday it plans to invest up to $10 million in a new coal power plant in western Washington state.
The company said the plant would be part of a new expansion of the company’s Powder River Basin power production and export facility in the area.
It will be the largest coal plant in the U.S. to be built using the process of natural gas and steam.
Puget Sound Power also has a major coal-burning power plant near Bellingham, Washington.
It is a member of the Pacific Northwest Power Administration (PNA), which was founded in the 1990s to develop and finance coal-generated electricity.
The Puget Power plant, scheduled to be completed in 2021, will use more than 200 million tons of coal annually and will produce electricity to cover its power demand in Puget County, where it is located.
The new plant is also expected to produce up to 60 percent more electricity than its predecessor, according to the Puget Project.
