Project Debt Service Coverage Ratio
Definition
The project debt service coverage ratio (DSCR) is cash available for debt service divided by scheduled interest and principal for the same period, usually twelve months. In project finance it is used twice: before closing, to size the loan so that forecast coverage meets minimum ratios under base and downside cases; after closing, as a test that must be met before cash can be distributed to equity. The general credit measure is covered on the debt service coverage ratio page.
Why it matters
For equity investors in a leveraged project, the DSCR test is the gate in front of every distribution. A modest fall in output or prices that leaves the project profitable can still stop distributions for several quarters. Investors should ask what coverage the base case shows, how far it sits above the lock-up threshold, and how much revenue can fall before distributions stop.
Common misconceptions
- •A sizing ratio and a distribution test are different numbers; the lock-up level is usually lower than the sizing minimum.
- •Coverage above 1.0x does not mean equity is paid; the distribution threshold is higher.
- •Ratios are calculated on the loan agreement's CFADS, not on reported earnings.
- •Merchant cash flows are sized at higher ratios because lenders discount them.
Technical details
Worked example (illustrative): profitable and locked up
CFADS $12.5 million; debt service $10.0 million; DSCR 1.25x; distributions permitted.
A weak resource year cuts CFADS by 8.8% to $11.4 million; the project still earns a profit and pays its lenders in full.
DSCR falls to 1.14x, below a 1.15x distribution test; cash above the senior steps goes to a reserve account instead of equity.
Equity receives nothing for the period even though revenue fell less than 9%.
Sizing cases in the Pelican's Jaw financing
Solar, contracted cash flows: 1.25x at P50 and 1.00x at P99.
Solar, merchant cash flows (excluding merchant RECs): 1.75x at P50 and 1.40x at P99, plus a P90 cash sweep test.
Battery, contracted cash flows: 1.20x; merchant cash flows before the PPA delivery term: 2.00x at P50.
How investors apply the term
Investors usually apply this term by tying the definition back to the controlling documents and then asking which cash flows, rights, restrictions, or valuation assumptions it changes. A useful review looks at the term alongside fees, leverage, liquidity, reporting frequency, and manager discretion rather than treating it as a standalone concept.
The practical diligence test is simple: identify who benefits if the assumption is wrong, who has control when conditions change, and what evidence the investor receives after closing. Terms that cannot be reconciled to documents, cash movements, and monitoring data should be treated as marketing shorthand until proven otherwise.
Frequently asked questions
- Why can an energy project have positive earnings but no distributions?
- Because distributions depend on a coverage test, not on earnings. In the Pelican's Jaw financing agreement, filed as an exhibit to SB Energy's 2026 S-1, the borrower can distribute only if, among other conditions, 'the Debt Service Coverage Ratio ... is not less than 1.15:1.00.' A project covering its debt 1.10 times is paying its lenders and may be profitable, but its equity receives nothing until coverage recovers.
- How is the loan sized with it?
- Against several cases at once. The Pelican's Jaw term loan had to show coverage over its amortization period of at least 1.25x on contracted cash flows at P50 output, 1.00x at P99, 1.75x on merchant cash flows at P50 and 1.40x at P99 for the solar project, and 1.20x on contracted cash flows for the battery. The loan is the largest amount that passes every test, so higher-risk cash flows support less debt per dollar.
- Who calculates it?
- The borrower, with the lenders checking. Pelican's Jaw's borrower delivers its calculation within 45 business days of each payment date; the administrative agent can comment, and if the calculation is not delivered, 'no funds shall be released' to the borrower.
