The DOE's Loan Programs for Energy Projects

From the US Department of Energy:

The Loan Programs Office "has more than $40 billion in loans and loan guarantees available to help deploy large-scale energy infrastructure projects in the United States. Over the past decade, LPO has closed more than $30 billion of deals across a variety of energy sectors. Review our overview and subscribe to our newsletter to keep informed about the program.

"LPO provides debt financing for the commercial deployment of large-scale energy projects; however, for research, development, and demonstration (RD&D) and smaller projects, other offices within DOE offer funding and financing opportunities."
