Two coal units would be phased out under PSO’s regional haze plan

Public Service Co. of Oklahoma would retire its last remaining two coal units at a power plant near Oologah, Okla. by 2026 under a regional haze plan proposed to the state Department of Environmental Quality, according to a report by The Oklahoman.

PSO stated it wants to retire one of the coal units at its Northeastern Station power plant in 2016 and install emissions control technology on the second unit, according to the report. Generation from the second unit would be gradually decreased until its retirement by 2026.

The federal plan for controlling regional haze involved installing dry scrubbers in coal-fired units. The utility devised its own plan for dealing with regional haze regulations after reaching a settlement last year with the U.S. Environmental Protection Agency, the Oklahoma Secretary of the Environment and the Sierra Club, according to The Oklahoman.

According to PSO, its plan to retire the two coal-fired units could cost around $350 million and raise customer rates by at least 11 percent beginning in 2016, The Oklahoman reported.
