I knew I had to back into the required profit first: 10% of $400M is $40M.
First, calculate the required annual profit by multiplying the investment by the ROI (10% of $400M = $40M). Then, express total annual costs as a function of annual MWh output, including land lease, fixed O&M, and variable costs. Finally, set up the profit equation (Revenue - Costs = $40M) and solve for the minimum MWh output.
Pro tip: Always state your assumptions clearly (e.g., 12 months per year, no other costs) and round up to the nearest whole MWh to ensure the ROI target is met. This shows attention to detail and business acumen.
Multiply the investment amount by the ROI percentage to find the target profit: 0.10 * $400M = $40M.
Convert the monthly land lease to annual ($5M/month * 12 = $60M/year) and add fixed O&M ($25M/year) to get total fixed costs of $85M/year.
Let Q be annual MWh output. Total costs = fixed costs + variable costs = $85M + $20Q. Total revenue = selling price * Q = $40Q.
Profit = Revenue - Costs = $40Q - ($85M + $20Q) = $20Q - $85M. Set profit equal to $40M: $20Q - $85M = $40M, so $20Q = $125M, Q = 6.25M MWh.
Check that at Q = 6.25M MWh, profit is exactly $40M. Since output is typically in whole MWh, round up to 6,250,000 MWh to ensure the ROI target is met.

Pretty quick check once you have the first answer.
First, clarify the units and assumptions behind the 6.25M MWh ROI target—is it annual energy output, revenue, or savings? Then, compare it to the 8.8M MWh maximum capacity, considering realistic capacity factors, downtime, and efficiency losses. Conclude whether the target is achievable and discuss any operational or analytical adjustments needed.
Pro tip: Show that you understand the difference between theoretical maximum capacity and actual achievable output by referencing typical capacity factors (e.g., 80-90% for baseload plants) and the impact of maintenance, fuel supply, and market demand.
Ask what the 6.25M MWh ROI target represents—annual generation, energy savings, or revenue equivalent—and whether it is gross or net of losses.
Calculate the effective annual capacity by applying a realistic capacity factor (e.g., 85-95%) to the 8.8M MWh maximum, accounting for planned and unplanned outages.
Compare the effective capacity to the 6.25M MWh target to see if it falls within the achievable range; if not, identify the gap and potential causes.
Discuss how market demand, fuel availability, regulatory constraints, and operational efficiency could further limit output below the effective capacity.
Suggest data-driven actions such as sensitivity analysis, benchmarking against similar plants, or revising the target based on realistic assumptions.

Flip the earlier equation: total costs including the $40M ROI target divided by 8.8M MWh.
First, clarify that break-even price equals total costs divided by total MWh generated, assuming all capacity is sold. Then, structure your answer by identifying all cost components (fixed and variable), calculating total annual costs, and dividing by 8.8 million MWh to get the break-even price per MWh. Finally, discuss how this price informs pricing strategy and profitability analysis.
Pro tip: Demonstrate business acumen by noting that break-even price is a floor, not a target—actual pricing should consider market demand, competition, and value-based factors. Also, mention sensitivity analysis to show how changes in cost or capacity affect the break-even point.
Confirm that 'full capacity' means 8.8 million MWh generated and sold annually, and that break-even means total revenue equals total costs (zero profit).
List all costs: fixed costs (e.g., capital, maintenance, labor) and variable costs (e.g., fuel, consumables) per MWh. Ensure all costs are annualized.
Sum fixed costs and variable costs (variable cost per MWh multiplied by 8.8M MWh) to get total annual costs.
Divide total annual costs by 8.8M MWh to get the break-even selling price per MWh.
Discuss how this price compares to market prices, and consider sensitivity to changes in costs or capacity utilization.

First, clarify the assumptions: the initial selling price is $40/MWh, the ROI target is 10%, and we need to find the new required annual generation after a 10% price drop. Then, set up the ROI equation using the original scenario to derive the relationship between generation, price, and ROI, and solve for the new generation volume that maintains the 10% ROI at the reduced price.
Pro tip: State your assumptions explicitly and walk through the algebra step-by-step; this demonstrates structured thinking and ensures the interviewer can follow your logic. Also, mention that in real-world scenarios, you'd validate these assumptions with historical data and consider factors like demand elasticity and operational constraints.
Confirm that the initial price is $40/MWh, ROI target is 10%, and that costs and other factors remain constant. Define variables: let Q be the original annual generation (MWh), and let C be the total annual cost.
Express the original ROI as (Revenue - Cost) / Cost = 10%. Revenue = 40 * Q, so the equation is (40Q - C) / C = 0.10. Solve for C in terms of Q: C = 40Q / 1.10.
After a 10% drop, the new price is $36/MWh. Let Q_new be the new annual generation. The new ROI equation is (36 * Q_new - C) / C = 0.10. Substitute C from step 2.
Substitute C = 40Q / 1.10 into the new equation: (36 Q_new - 40Q/1.10) / (40Q/1.10) = 0.10. Simplify to find Q_new in terms of Q. The result is Q_new = (40/36) * Q = 1.111... * Q, meaning generation must increase by approximately 11.11%.
Explain that to maintain the same ROI after a 10% price drop, the annual generation must increase by about 11.11% (or a factor of 10/9). Discuss practical implications, such as whether this increase is feasible and potential trade-offs.

1,000 MWh/day is only 365,000 MWh/year, which is catastrophically below the 6.25M target.
First, clarify the ROI requirement and the baseline demand or production target, then compute the annual shortfall as the difference between the required annual output and the constrained 1,000 MWh/day (365,000 MWh/year). Next, identify two levers—such as increasing output capacity or reducing the ROI target—and quantify their potential impact to close the gap.
Pro tip: Always state your assumptions explicitly (e.g., 365 days per year, constant daily output) and show the math step-by-step; this demonstrates rigor and helps the interviewer follow your logic. Also, consider non-obvious levers like demand-side management or pricing adjustments that could effectively reduce the required output.
Ask or state the annual ROI target (e.g., required annual output or revenue) and the current or planned production capacity. Confirm the time period (365 days) and whether the 1,000 MWh/day constraint is firm.
Compute the constrained annual output: 1,000 MWh/day * 365 = 365,000 MWh/year. Subtract this from the ROI-required annual output to get the shortfall. If the ROI requirement is not given, express the shortfall as a formula or ask for it.
Brainstorm levers such as: (1) increasing output capacity (e.g., adding production units, improving efficiency), and (2) reducing the ROI requirement (e.g., adjusting pricing, cutting costs, or renegotiating targets). Ensure they are actionable and quantifiable.
Estimate how much each lever can contribute to closing the shortfall. For example, if capacity can be increased by X MWh/day, that adds X*365 MWh/year. If ROI target can be reduced by Y%, that reduces the required output.
Propose a mix of the two levers, showing how together they can close the gap. Discuss trade-offs, feasibility, and any additional data needed.
