Determine Optimal Energy Project for 10% ROI Target
Investment Selection and ROI Sizing for a New Renewable Project
Scenario
An energy company is evaluating investments in new renewable projects and must hit a 10% annual return on investment (ROI). Fixed and variable costs differ between two technologies:
- (a) Solar with zero variable cost
- (b) An alternative technology with a $30/MWh variable cost
To make the questions concrete and internally consistent with the provided “expected” answers, assume the following for calculations:
- Market price for electricity (P): $40/MWh
- Annual fixed O&M (F): $12.5 million
- Corporate capital allocated to a representative project (I): $500 million (for Q-sizing in part 2)
- Annual production cap (Q_max): 5.0 × 10^6 MWh (5 TWh)
- Variable costs: solar v = $0/MWh; alternative v = $30/MWh
Questions
-
What qualitative and quantitative factors would you consider when selecting a new energy project?
-
If the target is a 10% annual ROI, how many MWh must be produced each year to reach it? (Expected: 6.25 × 10^6 MWh)
-
Production is capped at 5.0 × 10^6 MWh per year. What actions could still deliver a 10% annual ROI?
-
Two options exist:
- (a) Solar with zero variable cost
- (b) Alternative technology with $30/MWh variable cost
For each, calculate years to breakeven; both should be approximately 2.5 years. Show your math.
-
Which option would you recommend and why?
-
In 30 seconds, summarize your analysis and recommendation to senior management.
Hints
Use ROI = (annual profit) / (initial investment). Factor in price per MWh, capex, opex, subsidies, risk, scalability, and regulatory constraints.
