REP Project Planning & Financial Analysis 4 — Questions and Answers
Question 1: A battery storage project paired with solar earns revenue through energy arbitrage. Which market mechanism allows it to also earn capacity payments in many US wholesale markets?
- Renewable Energy Certificate (REC) markets
- Capacity markets or resource adequacy programs (Correct answer)
- Carbon credit trading programs
- Net metering programs
Correct answer: Capacity markets or resource adequacy programs
Capacity markets compensate resources for being available during peak demand periods, providing a revenue stream independent of actual energy production.
Question 2: Which financial metric is most commonly used by lenders as a covenant in renewable energy project finance loan agreements?
- Internal Rate of Return (IRR)
- Net Present Value (NPV)
- Debt Service Coverage Ratio (DSCR) (Correct answer)
- Modified Accelerated Cost Recovery System (MACRS) basis
Correct answer: Debt Service Coverage Ratio (DSCR)
DSCR measures a project's ability to cover debt payments from operating cash flow and is the primary covenant lenders monitor throughout the loan term.
Question 3: A developer is planning a 50 MW solar project and must post a transmission deposit with the grid operator. This deposit is typically based on:
- The project's expected annual energy production
- A per-MW amount set by the interconnection tariff to fund study costs and network upgrades (Correct answer)
- The land lease cost for the project site
- The anticipated REC revenue over the first five years
Correct answer: A per-MW amount set by the interconnection tariff to fund study costs and network upgrades
Interconnection deposits are set by tariff on a per-MW basis and cover the cost of interconnection studies and, ultimately, required system upgrades.
Question 4: In US project finance, a 'tax equity flip' structure refers to the point at which:
- The project switches from fixed-price to merchant electricity sales
- The tax equity investor's ownership percentage decreases after achieving its target return (Correct answer)
- The project refinances its construction loan with a permanent term loan
- The developer sells its equity stake to a long-term infrastructure fund
Correct answer: The tax equity investor's ownership percentage decreases after achieving its target return
After the tax equity investor has claimed sufficient tax credits and depreciation to reach its target IRR, its ownership share flips down (typically from ~99% to 5%), leaving the developer with majority control.
Question 5: Which renewable energy project development risk is best characterized as 'basis risk'?
- The risk that construction costs exceed the EPC contract price
- The difference between the PPA price and actual market prices at the delivery point (Correct answer)
- Uncertainty in the project's capacity factor due to weather variability
- The risk that permitting delays extend the construction timeline
Correct answer: The difference between the PPA price and actual market prices at the delivery point
Basis risk is the difference between the nodal price where a generator delivers power and the hub or reference price used in a financial hedge or PPA.
Question 6: A renewable energy project's 'P90 energy estimate' means that:
- 90% of the installed capacity will operate at full output
- There is a 90% probability that actual energy production will meet or exceed this estimate (Correct answer)
- 90% of project revenue is contractually guaranteed through a PPA
- The project will achieve commercial operation within 90 days of its target date
Correct answer: There is a 90% probability that actual energy production will meet or exceed this estimate
P90 is an exceedance probability: the energy yield that will be met or exceeded with 90% confidence, representing a conservative estimate used for debt sizing.
Question 7: Which type of offtaker agreement provides the most revenue certainty for a utility-scale solar project seeking non-recourse project financing?
- A short-term spot market arrangement
- A 20-year fixed-price PPA with a creditworthy investment-grade counterparty (Correct answer)
- A virtual PPA (VPPA) with a corporate buyer
- A merchant revenue arrangement hedged with financial contracts
Correct answer: A 20-year fixed-price PPA with a creditworthy investment-grade counterparty
A long-term fixed-price PPA with an investment-grade counterparty provides the predictable, contracted revenue stream that lenders require for non-recourse financing.
