Clean Air Technologies

SCE&G strives to provide low-cost, reliable energy, while at the same time minimizing the impact its operations have on the environment. To reduce the emission of the oxides of nitrogen that can cause ozone, the sulfur dioxide that can cause acid rain, as well as particulates, we have invested hundreds of millions of dollars in state of the art air pollution control technology, to include dry scrubbers, selective catalytic reduction units, and baghouses for our coal-burning plants. These technologies work to clean emissions before they leave the stack and can go into the atmosphere. In the case of our baghouses, the ash recovered from them is recycled into useful products like cement. SCE&G recently retrofitted a coal burning plant that was built in the 1950s with combined cycle turbines, allowing the plant to replace coal with clean-burning natural gas. The company's most recent addition to its generating capacity is also a combined cycle plant specifically designed and built with significant environmental controls.
