Read the first 7 Financial Management & Budgeting flashcards as text

  1. A company finances a $600,000 BESS project with 60% equity and 40% debt at 7% interest. The equity investors require a 12% return. What is the Weighted Average Cost of Capital (WACC)?

    Answer: 9.6%

    WACC = (0.60 × 12%) + (0.40 × 7%) = 7.2% + 2.8% = 10.0%; after-tax adjustments often lower the debt component, but here WACC ≈ 10%.

  2. A sensitivity analysis on a BESS financial model shows the project NPV is most sensitive to changes in electricity price. This means:

    Answer: Small changes in electricity price have the largest impact on project viability

    Sensitivity analysis identifies which input variable causes the greatest swing in NPV, guiding risk management efforts on that key driver.

  3. Operating & Maintenance (O&M) costs for a lithium-ion BESS are typically estimated as what percentage of initial capital cost per year?

    Answer: 1–3%

    Industry benchmarks place annual O&M costs for utility-scale lithium-ion BESS at roughly 1–3% of initial capital cost per year.

  4. A BMS financial manager must choose between leasing and purchasing battery hardware. Which factor most favors leasing?

    Answer: The company wants to avoid obsolescence risk as technology rapidly improves

    Leasing transfers technology obsolescence risk to the lessor, which is especially valuable in fast-moving markets like battery technology.

  5. An energy storage project's pro forma shows positive EBITDA but negative free cash flow. The most likely reason is:

    Answer: Large debt principal repayments not captured in EBITDA

    EBITDA excludes debt principal repayments; large loan amortization payments reduce free cash flow even when EBITDA is positive.

  6. Under the Inflation Reduction Act (IRA), standalone battery storage systems in the US qualify for the ITC if they meet which minimum capacity threshold?

    Answer: 1 kWh

    The IRA extended the ITC to standalone storage systems with a capacity of at least 1 kWh, removing the requirement to pair with solar.

  7. A BMS project budget includes a 10% contingency reserve. This reserve is intended to cover:

    Answer: Unforeseen costs and scope changes during project execution

    Contingency reserves are budgeted to handle unexpected cost overruns, scope changes, or unplanned events during project implementation.
