  1. A BESS project earns revenue through energy arbitrage by charging at $0.05/kWh off-peak and discharging at $0.15/kWh on-peak. With a round-trip efficiency of 85%, what is the net revenue per kWh discharged?

    Answer: $0.091/kWh

    Cost to charge per kWh discharged = $0.05 ÷ 0.85 = $0.0588; net revenue = $0.15 - $0.0588 ≈ $0.091/kWh.

  2. Which accounting treatment is correct for a battery cell replacement that extends the useful life of a BESS asset?

    Answer: Capitalize it as a capital improvement (CapEx)

    Costs that extend an asset's useful life or improve its capacity must be capitalized (CapEx) rather than expensed in the current period.

  3. A demand charge reduction program saves a facility $8,000/month. Over a 12-month budget period, what is the total projected budget savings?

    Answer: $96,000

    $8,000/month × 12 months = $96,000 in annual demand charge savings.

  4. A battery project's financial model uses a real discount rate of 5% but actual inflation is 3%. What is the approximate nominal discount rate?

    Answer: 8%

    Nominal rate ≈ real rate + inflation rate = 5% + 3% = 8% (Fisher approximation).

  5. A facility manager prepares a 5-year capital budget for battery system upgrades. This planning horizon is best described as:

    Answer: A rolling capital expenditure plan

    A multi-year forward-looking plan for capital asset investments is called a rolling capital expenditure (CapEx) plan or capital budget.

  6. When conducting a Total Cost of Ownership (TCO) analysis for a BESS, which cost is most commonly overlooked in initial budgets?

    Answer: Battery disposal and end-of-life recycling costs

    End-of-life battery disposal, recycling compliance costs, and decommissioning are frequently omitted from initial TCO estimates but can be significant.

  7. A BESS project qualifies for a $50,000 state rebate paid upon commissioning. In the financial model, this rebate should be treated as:

    Answer: A reduction in the net capital cost (negative CapEx)

    Government rebates received upon commissioning reduce the effective capital cost of the asset, lowering the net investment basis used in NPV and payback calculations.
