IAMU Biodiesel Testing

By conducting research, IAMU aims to encourage and empower its member utilities to use biodiesel in diesel generators.  This page provides information on the current status of those efforts and general resources on biodiesel.

2006 Efforts

In February 2006, IAMU was awarded a grant from the Iowa Energy Center to conduct biodiesel emissions tests on stationary electric generators.  From September 25 to October 5, 2006, emissions tests were conducted at Winterset Municipal Utilities and the Story City Municipal Electric Utility. Both utilities  allowed emissions tests to be conducted using biodiesel blends of up to B20 (20% biodiesel) in their generators.  B100 emissions tests were also conducted in Story City.

Emissions data for NOx, CO, and PM are being processed currently, but information will be made public in late 2006 or early 2007, and biodiesel will be discussed at the 2006 IAMU Diesel Generation Workshop on December 12-14, 2006.

IDNR 2005 Rule Change

Iowa Department of Natural Resources (IDNR) new rule allows the usage of up to 2% biodiesel in all stationary generators in Iowa. Note: Utilities can burn up to B2 in their generators without having to modify their operating permits. If utilities want to burn between B3 and B10, they must contact the Iowa DNR and modify their operating permits first.
