SMECO must revise its base energy rate if the PCA for three consecutive months is 5 percent more or less than the base energy rate. Since SMECO’s PCA for May was -5.79 percent of the current average annual base energy charge and that is over the trigger level of 5 percent for one month, SMECO’s base energy rate will remain unchanged at this time.
