The Energy Information Administration says ethanol output plunged to its lowest level in almost seven months during the week ending on April 15. Ethanol inventories also dropped to multi-month lows. Ethanol production fell to an average of 947,000 barrels a day during the week. The EIA report says that’s down significantly from the 995,000 barrels a day produced during the previous week. It’s also the lowest production level since the seven days ending on September 24. In the Midwest, the biggest-producing region of the country, output hit 889,000 barrels a day, down from 935,000 barrels a week earlier and the lowest level since late September. Gulf Coast and West Coast production levels dropped by 1,000 barrels a day, while output on the East Coast and in the Rocky Mountain region stayed steady with the previous week. Ethanol inventories fell to 24.34 million barrels, the lowest level since the week ending on January 14.
