Financial Management & Budgeting Flashcards

A battery energy storage system (BESS) costs $500,000 installed and saves $60,000/year in demand charges. What is the simple payback period?

Answer: 8.3 years

Simple payback = $500,000 ÷ $60,000/year = 8.33 years.

Which financial metric accounts for the time value of money when evaluating a long-term BESS investment?

Answer: Net Present Value (NPV)

NPV discounts future cash flows to present value, properly capturing the time value of money over a project's life.

A battery system has a 10-year useful life and cost $400,000. Using straight-line depreciation, what is the annual depreciation expense?

Answer: $40,000

Straight-line depreciation = $400,000 ÷ 10 years = $40,000/year.

When budgeting for a BMS replacement project, which cost category covers ongoing software license renewals?

Answer: Operating expenditure (OpEx)

Recurring costs like software licenses are classified as operating expenditures (OpEx), not one-time capital costs.

The Internal Rate of Return (IRR) of a battery project is 12%. If the company's cost of capital is 15%, what should the financial manager recommend?

Answer: Reject — IRR is below the required rate of return

A project should be rejected when its IRR is below the company's cost of capital (hurdle rate), as it destroys value.

Which federal incentive program most directly reduces the upfront capital cost of a commercial battery storage installation in the US?

Answer: Investment Tax Credit (ITC)

The Investment Tax Credit (ITC) under the Inflation Reduction Act provides a direct percentage credit on qualifying battery storage system costs.

A budget variance report shows actual BMS maintenance costs are 20% above the planned budget. This is best described as:

Answer: An unfavorable variance

When actual costs exceed budgeted costs, the variance is unfavorable (adverse), indicating overspending.
