I just found this article at Environmental News Service
Renewable Energy Developers Offered Cash In Lieu of Tax Credits
WASHINGTON, DC, July 10, 2009 (ENS) - The federal government will provide direct incentive payments instead of tax credits to renewable energy developers under a new $3 billion Recovery Act program announced today.
The grants are designed to temporarily replace the production tax credit that has been a major factor in the continued growth in wind and other renewable energy projects. The recession and the freeze in the credit markets that began late last year rendered the production tax credit much less useful as an investment incentive.
