After already receiving a controversial $1.6 billion construction loan from U.S. taxpayers, the wealthy investors of a California solar power plant now want a $539 million federal grant to pay off their federal loan.

“This is an attempt by very large cash generating companies that have billions on their balance sheet to get a federal bailout, i.e. a bailout from us – the taxpayer for their pet project,” said Reason Foundation VP of Research Julian Morris. “It’s actually rather obscene.”

The Ivanpah solar electric generating plant is owned by Google and renewable energy giant NRG, which are responsible for paying off their federal loan. If approved by the U.S. Treasury, the two corporations will not use their own money, but taxpayer cash to pay off 30 percent of the cost of their plant, but taxpayers will receive none of the millions in revenues the plant will generate over the next 30 years.

“They’re already paying less than the market rate,” said Morris, author of a lengthy report detailing alleged cronyism and corruption in the Obama administration’s green energy programs. “Now demanding or asking for a subsidy in the form of a grant directly paying off the loan is an egregious abuse.”
