Southern Company addresses emissions like mercury, nitrogen oxides, sulfur dioxide and particulate matter as part of the system’s commitment to environmental responsibility.

Wilsonville Plant

The Southern Company system’s dedication to environmental responsibility includes addressing emissions such as nitrogen oxides (NOX), sulfur dioxide (SO2) and mercury. We have cut SO2 emissions by 98 percent and reduced NOX emissions by 88 percent since 1990. What’s more, our system has lowered mercury emissions 89 percent from 2007 levels. We have achieved these reductions while continuing to reliably produce energy to meet the needs of millions of customers.
