New emissions control equipment dramatically improves air quality at DTE Energy’s Monroe Power Plant

DTE Energy (NYSE: DTE) has completed a project at the Monroe coal-fired power plant to reduce emissions and improve air quality in the region. DTE has invested nearly $2 billion since 2000 on environmental upgrades at the plant.

The facility, , which is the largest generating plant in Michigan and the fifth-largest in the country,  is the first in the state to operate best-in-class systems that reduce nitrogen oxide emissions by about 90 percent and sulfur dioxide emissions by about 97 percent. Combined, the selective catalytic reduction and flue gas desulfurization systems also eliminate 75- to 90-percent of mercury emissions.

“The Monroe Power Plant is a cornerstone of DTE Energy’s generating fleet,” said Frank Warren, DTE Energy vice president of fossil generation. “The start-up of the last selective catalytic reduction system helps us reach our goal of making one of the country’s largest coal-fired plants also one of the cleanest.”

Two 580-foot tall chimneys were constructed to support operation of the flue gas desulfurization systems. The last remaining 800-foot smokestack is in the process of being taken down.

“This allows DTE to continue giving our customers reliable, affordable energy while minimizing any impact on the environment. We are proud of DTE’s role in improving air quality in Michigan, which is better today than it has been in the last 40 years due in large part to emissions reductions at our coal-fired power plants,” said Skiles Boyd, DTE Energy vice president of environmental management and resources.
