What are the U.S. EPA’s federal greenhouse gas regulations?

The U.S. EPA is currently in the process of establishing greenhouse gas regulations that would limit carbon dioxide emissions for new power plants and existing power plants, as part of the Clean Air Act.

The EPA first re-proposed its regulations in September 2013 to limit CO2 emissions from all new natural gas and coal-fired power plants. Closely on its heels, the agency also released the regulation’s counterpart in June 2014 to limit CO2 emissions from existing power plants.

On Aug. 3, President Obama unveiled the U.S. Environmental Protection Agency's much-anticipated final regulations to limit CO2 emissions from existing power plants. Learn more about the company's response. 

How are LG&E and KU decreasing emissions?

LG&E and KU are currently in the midst of an unprecedented number of construction projects to install extensive environmental controls to meet the requirements of other new U.S. EPA rules including the Mercury and Air Toxics Standards, Cross State Air Pollution Rule, and revised National Ambient Air Quality Standards.  

The company will have spent more than $3 billion from 2009-2015 to further decrease emissions across the coal-fired fleet.

The company is fully rehabilitating all eight generating units at the Ohio Falls hydroelectric plant that will increase total output by 27 percent. Ohio Falls and Dix Dam hydro plants will have the ability to produce up to 120 megawatts.

The new 640-megawatt natural gas combined-cycle generating unit under construction at Cane Run and the retirement of 13 percent of the company’s coal-fired units also will decrease the company’s long-term CO2 emission levels.
