SUMMARY OF FINDINGS The Southwestern Electric Power Company (SWEPCo), which provides electricity to about 450,000 customers in the Arkansas-Louisiana-Texas region has projected that the demand for electric energy will grow by as much as 1,600 megawatts (MW) by 2011. Arkansans soon must choose between two alternatives for accommodating this growth. One alternative involves generating electricity by burning coal. SWEPCo, a subsidiary of American Electric Power, seeks to build one 600-MW, coal-fired generator near Texarkana, Arkansas, in Hempstead County, by 2011. Its preliminary estimate of the total cost is $1.3 billion. The coal for the generator would be shipped in by rail from Wyoming. The other alternative does not involve burning coal. Instead, it entails investing in energy efficiency, so that energy savings could be used to meet new demands, and in new generators powered by wind, biomass, and other renewable resources. The choice between the two alternatives will have important economic consequences for Arkansas’ workers, families, landowners, and businesses. This report describes the tradeoffs, focusing on these four areas: Environmental Consequences. The generator proposed by SWEPCo would annually emit: 2,628 tons of sulfur dioxide 1,840 tons of nitrogen oxides 3,942 tons of carbon monoxide 920 tons of particulate
