BMS Financial Management & Budgeting 2

Question 1

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

Accepted Answer

8.3 years

Answer

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

Question 2

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

Accepted Answer

Net Present Value (NPV)

Answer

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

Question 3

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

Accepted Answer

$40,000

Answer

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

Question 4

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

Accepted Answer

Operating expenditure (OpEx)

Answer

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

Question 5

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?

Accepted Answer

Reject — IRR is below the required rate of return

Answer

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