Over 90% of flue gas desulfurization (FGD)-controlled power plant capacity in the U.S. utilizes lime or limestone as reagent. Coal plant retirements, FGD retrofits, and future changes in the country’s generation portfolio have a great impact on total lime and limestone demand.

EVA models individual coal unit generation, coal qualities, and FGD removal rates to build a bottoms-up approach in estimating future power industry reagent demand. EVA can forecast lime and limestone demand by generating facility, state, NERC region, or other customizable market area.
