On a conference call today, Rhone Resch of the Solar Energy Industries Association (SEIA), along with Ed Fenster, co-founder and CEO of SunRun, Mark Conroy, president and CEO of MegaWatt Solar, and Eric Hafter, senior vice president of Sharp Solar Energy Solutions Group called for a two-year extension of the Treasury Grant Program (TGP). The TGP allows investors in renewable energy project developments to take an upfront payment equal to 30% of the project's cost instead of filing for a tax credit for the same amount.
