In remarks to reporters later, he said that one solution would be for the government to subsidize the fee that a borrower would pay for a guarantee on a loan that the government considered high-risk. Or there could be other answers, he said. He declined to get more specific, but warned that without more aid, the financing could “dwarf the economics of the project."
In case people don't know how this works, it goes like this.
The government kicked the loan guarantees up from 50% to 80% of project cost because the costs are so great. This requires that the payback times extend so far into the future that predicting energy costs is impossible. This uncertainty is supposedly what is holding investors back.
To get that 80% loan guarantee, the borrowers are required to pay a fee upfront that is equal to that project's equal share of the "best guess" losses across the entire program. In other words if the total program is $50 billion spread across 7 projects and the Office of Management and Budget and Congressional Budget Office anticipate all but 2% of the $50 billion program will be repaid, then the anticipated 2% loss of $1 billion would be spread across the seven projects. If they all used an equal portion of the program that would come to about $143 million per project.
Additional funds are available under the regulations of some utilities by instituting rate increases that guarantee the payback of investors in the nuclear projects whether or not the plant ever generates electricity or not. This is how the projects under way are financing the other 20% not covered by the loan guarantees. No projects are being planned for jurisdictions that do not allow this practice.
There are a number of other guarantees also in place; for example, if they find a design flaw and have to tear down everything and start over, a significant portion of the cost is paid by taxpayers.
Now, they don't want to have to pay the fees?
Maybe it has something to do with the fact that there is no way to avoid the conclusion that most of the loans will probably go into default because of rapidly declining renewable energy costs and the rapid rate of expansion of renewable energy.
