Today the House passed, and President Bush signed into law, H.R. 1424, which includes the Energy Improvement and Extension Act of 2008 (the Act). The Act contains the much-anticipated extension of the production tax credit (PTC) and investment tax credit (ITC) sunset dates.

The Act extends the PTC placed-in-service sunset date for certain wind and refined coal facilities until December 31, 2009, and extends the PTC placed-in-service sunset date for certain other qualifying facilities until December 31, 2010. The Act also expands the PTC to include certain marine and hydrokinetic renewable energy facilities placed in service on or before December 31, 2011.

The Act extends the ITC placed-in-service sunset date for solar, fuel cell and microturbine property until December 31, 2016 and expands the ITC to include combined heat and power system property, qualified small wind energy property, and geothermal heat pump system property.

In addition, H.R. 1424 contains a variety of other renewable energy tax provisions, including provisions allowing the energy credit to offset alternative minimum tax liability; increasing the amount of the biodiesel and renewable diesel fuel credits and extending the sunset dates until December 31, 2009; authorizing new clean renewable energy bonds and qualified energy conservation bonds; and extending the energy efficient commercial buildings deduction and the new energy efficient home credit.
