A $1.45 billion loan guarantee is not $1.45 billion in cash. It's only an underwriting of the loans which Abengoa Solar will be taking out to build the solar plant. A sovereign guarantee reduces the cost of the loans since the banks face a much lower risk of default. The actual cost to the Government will be close to zero until and unless Abengoa Solar defaults on the loans, in which case the cost to the Government will be whatever proportion of the loan the banks are unable to recover.
