DSCR & debt capacity
Start with annual CFADS, a target DSCR, interest rate and tenor. The calculator estimates level annual debt service and an indicative debt amount.

These calculators are for early project questions: how much debt could the cash flow support, and does a PPA still save the buyer money after network and residual-supply costs?

Two useful first-pass checks
No sign-up. Use your own assumptions and keep the result as an indicative screen, not a lender or tariff opinion.
Corporate power
PPA & wheeling savings
Compare a grid-only bill with a wheeled renewable supply case after PPA energy, network charges and residual grid supply.

Once the answer depends on timing, contracts or downside cases.
A quick calculator is useful for screening. It is not a substitute for a project model when cash flow changes by month or year, debt is sculpted, tax and reserve accounts matter, or the PPA has detailed settlement rules.
If the first-pass result looks interesting, move into the underlying model and documents. That is where the financing and commercial risks become visible.
