Delivering clean electricity with sustained performance.
Exelon continues to invest in our clean energy portfolio to keep our air emission rates well below industry averages. In 2015, Exelon’s owned power generation resources showed sustained performance in delivering low-emission electricity in a challenging marketplace.
Exelon’s electricity generation plant emission rates were substantially lower than the industry’s 2014 emission rate averages: nitrogen oxide (NOx) 97 percent lower, sulfur dioxide (SO2) 99 percent lower, and carbon dioxide (CO2) 93 percent lower.
Exelon also expects to continue to play a constructive role in supporting regional air pollution reduction as the EPA continues to periodically evaluate and implement additional air pollution regulations.
Our generation portfolio has changed significantly.
Exelon has retired or sold nearly all of its coal-fired assets. That has significantly lowered our already low emissions owned generation emissions profile.
At the end of 2015, Exelon sold our remaining shares of two large coal-fired plants in western central Pennsylvania, as well as our ownership share of the Colver waste coal plant. With Exelon’s 26 megawatt interest in the Sunnyside waste coal plant being our only remaining interest in coal plant, CO2, NOx, SO2 and TRI emissions are significantly in 2015 than they were in 2014. We continue to deploy new zero emission wind and solar generation assets and are building several state-of-the-art combined cycle gas plants in Texas with very low emission rates.
