Evaluate Energy One's Transition to Renewable Energy Sources

Q: Evaluate Energy One's Transition to Renewable Energy Sources

This question evaluates financial modeling, capacity planning, unit economics, and scenario/sensitivity analysis skills applied to an energy transition case, testing a data scientist’s ability to interpret costs, revenues, and policy constraints within an energy-sector context and is categorized under Analytics & Experimentation.

Question

Energy Transition Case: Feasibility, Capacity, and Options

Context (assumptions to interpret the case)

Treat $/MWh values as constant market prices (pre-tax, ignore financing, depreciation, and inflation unless asked).
Fixed costs occur annually; variable costs scale with MWh produced.
Capacity figures are annual maximums unless capped by policy.

Questions

What factors would you consider when evaluating Energy One's transition from fossil fuels to renewable power?
Fossil-fuel plant economics:
- Max capacity: 8.8 million MWh/year
- Lease: $5 million/month (i.e.,$ 60 million/year)
- Other fixed cost: $25 million/year
- Variable cost: $20/MWh
- Revenue (price): $40/MWh
- Initial investment (capex): $400 million
2a. How many MWh are needed annually to recover 10% of the initial investment through operating profit? 2b. Does your calculated production volume make sense relative to the plant’s maximum capacity? Explain.
If government policy caps fossil-fuel generation at 5 million MWh/year, which alternative power sources should Energy One pursue and why?

3b. If no new power sources are added, what levers could keep profitability stable under the 5 million MWh cap?

Test plants:
- 4a. Solar test plant: $12.5 million capex; production: 75% sunny (150,000 MWh), 25% cloudy (50,000 MWh); variable cost$ 0/MWh; price $40/MWh. How many years to break even?
- 4b. Ethanol test plant: $2.5 million capex; production 100,000 MWh/year; variable cost$ 30/MWh; price $40/MWh. How many years to break even?
With no budget limit, which test plant would you recommend and why?
