The U.S. Treasury Department today released on its website additional guidance regarding the "begin construction" requirement for qualifying for the 30% ARRA cash grant. To qualify for the grant, a project either must be placed in service in 2009 or 2010 or, if construction begins on or before December 31, 2010, must be placed in service by a specified credit termination date (December 31, 2012 for large wind projects; December 31, 2013 for biomass, certain geothermal and other projects; and December 31, 2016 for solar and other projects).  For the Stoel Rives Energy Tax Alert on the topic, click here
