Emission Reductions:

NOx, SO2 and PM

Testing helps ensure compliance with environmental regulations and provides data that helps reduce the potential risk to human health associated with emissions.

Since 1990, our emissions of sulfur dioxide and nitrogen oxides are down over 80 percent, while electricity generation has increased about 30 percent to serve growing demand. Performance »

Through 2015, the Southern Company system:

  • Invested about $9.4 billion in environmental controls. We are planning to spend at least an additional $2.1 billion through 2018.
  • Developed, with U.S. Department of Energy and KBR, the TRIGTM advanced coal gasification technology. This technology turns coal into gas that can be used to generate electricity more cleanly than traditional coal-fired power plants.
  • Advanced one-of-a-kind, clean coal power generation, in partnership with the U.S. Department of Energy at the National Carbon Capture Center in Wilsonville, Ala.

Particulate Matter and Air Quality Research

Southern Company participates in data collection and research studies aimed at characterizing air quality, its sources, and health effects. Two leading studies, SEARCH and ARIES, have provided a foundation for air quality policy, practices and emerging issues.

SEARCH comprehensively measures air quality in the Southeast, including the myriad compounds comprising particulate matter and is used in a variety of air quality research and regulatory analyses, including studies on health effects. SEARCH hosted the summer of 2013, $20 million Southeast Atmosphere Study sponsored by NSF, NOAA, EPA, EPRI, and others focused on understanding the interactions of natural and man-made emissions in forming particulate organic matter. ARIES investigates associations between specific air pollution components and human health.
