REP Project Finance and Economics 4 — Questions and Answers
Question 1: What is the primary function of a 'P50' energy production estimate in renewable project finance?
- The production level with a 50% probability of being exceeded, used as the base-case revenue forecast (Correct answer)
- The maximum possible production under ideal weather conditions
- The minimum contractually guaranteed output under a PPA
- The production level at which the project breaks even on a cash basis
Correct answer: The production level with a 50% probability of being exceeded, used as the base-case revenue forecast
P50 represents the median (50th percentile) energy production forecast; lenders often size debt to P90 output (exceeded 90% of the time) for conservative coverage.
Question 2: Which of the following is a key advantage of using a sale-leaseback structure in renewable energy project finance?
- It eliminates the need for an interconnection agreement with the grid operator
- It allows the developer to receive upfront capital while retaining operational control through the lease (Correct answer)
- It qualifies the project for higher ITC percentages than a direct ownership model
- It removes the requirement for an independent engineer report during due diligence
Correct answer: It allows the developer to receive upfront capital while retaining operational control through the lease
In a sale-leaseback, the developer sells the project to a tax equity investor or lessor and leases it back, immediately monetizing the asset while continuing to operate it.
Question 3: What does 'sensitivity analysis' reveal in a renewable energy project financial model?
- The specific year in which the project will achieve its target IRR under base-case assumptions
- How changes in key input variables (e.g., energy price, capacity factor) affect project returns and debt coverage (Correct answer)
- The likelihood that the project will be curtailed by the grid operator in any given year
- The optimal debt-to-equity ratio to maximize the project's credit rating
Correct answer: How changes in key input variables (e.g., energy price, capacity factor) affect project returns and debt coverage
Sensitivity analysis systematically varies one or more assumptions to show how project metrics (IRR, DSCR, NPV) respond to adverse or favorable changes in inputs.
Question 4: In the context of renewable energy project finance, what is 'interest rate risk' and how is it typically managed?
- The risk that government subsidies will be reduced; managed by locking subsidies in long-term legislation
- The risk that floating interest rates will rise, increasing debt service costs; typically managed with interest rate swaps or fixed-rate debt (Correct answer)
- The risk that the central bank will tighten credit, making refinancing impossible after construction
- The risk that tax equity investors will demand a higher return, reducing the sponsor's equity IRR
Correct answer: The risk that floating interest rates will rise, increasing debt service costs; typically managed with interest rate swaps or fixed-rate debt
Projects with variable-rate construction or term loans use interest rate swaps (pay-fixed, receive-floating) to convert floating exposure to a predictable fixed obligation.
Question 5: A project sponsor contributes $20M in equity to a $100M wind farm. What is the project's debt-to-equity ratio?
- 4:1 (Correct answer)
- 5:1
- 3:1
- 0.25:1
Correct answer: 4:1
Debt = $100M − $20M = $80M; debt-to-equity = $80M ÷ $20M = 4:1, indicating significant financial leverage.
Question 6: What is the role of an 'independent engineer' (IE) in renewable energy project finance?
- To negotiate PPA pricing on behalf of the project developer
- To provide third-party technical verification of energy yield estimates, construction plans, and contractor capabilities for lenders (Correct answer)
- To operate the facility on behalf of lenders in the event of a default
- To audit the financial model and certify the project's IRR projections
Correct answer: To provide third-party technical verification of energy yield estimates, construction plans, and contractor capabilities for lenders
Lenders hire an IE to independently validate the technical assumptions (resource assessments, equipment specs, contractor track record) underpinning the financial projections.
Question 7: Which of the following best describes 'curtailment risk' and its financial impact on a renewable energy project?
- The risk that the PPA counterparty will request early termination, reducing revenue certainty
- The risk that grid operators will instruct the project to reduce or stop output, resulting in lost revenue (Correct answer)
- The risk that equipment will underperform rated capacity due to manufacturing defects
- The risk that fuel costs will increase, raising variable operating expenses
Correct answer: The risk that grid operators will instruct the project to reduce or stop output, resulting in lost revenue
Curtailment occurs when the grid cannot absorb available renewable generation; the project loses energy sales it cannot recover, directly reducing cash flow and debt coverage.
