Competition for ethanol between refiners and fuel companies soared after the additive was phased in as the primary blending component in cleaner-burning gasoline, and the use of a rival additive methyl tertiary butyl ether, known at MTBE, was reduced. ``The MTBE switch created an inordinate demand for ethanol,' said Sal Gilbertie, an energy trader for Fimat USA in New York. ``And the new plants aren't yet ready' to produce more. U.S. ethanol averaged a record $3.9757 a gallon today, up 4.1 percent from $3.8194 since June 30, according to data compiled by Bloomberg. That average, based on ethanol traded in Des Moines and 29 other Midwest locations, was more than double $1.5929 a year ago and up 67 percent since the end of March.
