The American Recovery and Reinvestment Act, a $787 billion economic stimulus package passed by Congress on
February 13, 2009, and signed by President Obama on February 17, 2009, contained a three-year extension of the
Section 45 production tax credit for renewable energy. By extending the incentive program to 2012 and passing
an additional one-year extension through 2013, Congress ensured that the remarkable growth of wind power in
Iowa continued, along with the economic opportunities and emissions-free energy that it provides.
From its creation in the Energy Policy Act of 1992, the wind energy production tax credit has spurred the
growth of clean, emissions-free wind energy for MidAmerican Energy’s customers. By encouraging investment
in equipment and facilities associated with the generation of electricity from wind, the production tax
credit also promotes U.S. jobs in construction, manufacturing and maintenance.
