Project finance transactions, especially utility-scale, require a highly-detailed financial model. Abacus provides cash flow analysis on a monthly basis, helping maximize debt financing and IRRs, and uncover cash flow issues that may arise from seasonal or intermittent revenues and expenses. Abacus includes fully-linked financial statements (income statement, balance sheet, cash flow statement), and over a dozen built-in error checks to guard against unintended mistakes. It also includes two easy-to-use macros which can 1) sculpt project debt to a target debt service coverage ratio (DSCR), and 2) maximize debt used against maximum leverage and minimum DSCR inputs. Abacus also provides summary information ready for presentations to financing parties, including charts, IRR, DSCR, LLCR, and other metrics, as well as quarterly and annual financial statements.

  • Awesome, Extremely useful !

    It is a very comprehensive model, it allows you to understand how the Solar Farm will function and the different/outputs or scenarios that will play out.

    Plug and play. Once you enter the inputs and run the background check, it is very easy to understand and has a very round review of the project.
