EMP EMP Energy Economics & Financial Analysis 1 — Questions and Answers
Question 1: What financial metric measures the time required for an energy investment to generate enough savings to recover its initial cost?
- Simple payback period (Correct answer)
- Net present value
- Internal rate of return
- Return on equity
Correct answer: Simple payback period
Simple payback period divides the initial investment cost by the annual energy savings to determine how many years until the project pays for itself.
Question 2: Which of the following best describes Life Cycle Cost Analysis (LCCA) in energy management?
- Evaluating only installation costs of equipment
- Assessing total ownership costs including energy, maintenance, and disposal over a project's lifespan (Correct answer)
- Comparing utility rates across different providers
- Calculating annual energy consumption only
Correct answer: Assessing total ownership costs including energy, maintenance, and disposal over a project's lifespan
LCCA considers all costs—initial, operating, maintenance, and disposal—over a system's entire lifespan to support better investment decisions.
Question 3: An energy manager calculates that a lighting retrofit saves $12,000/year and costs $36,000 to install. What is the simple payback period?
- 2 years
- 3 years (Correct answer)
- 4 years
- 5 years
Correct answer: 3 years
$36,000 ÷ $12,000/year = 3 years simple payback period.
Question 4: What is the purpose of a Measurement and Verification (M&V) plan in an energy performance contract?
- To negotiate lower utility rates
- To document and confirm that energy savings have been achieved as promised (Correct answer)
- To identify new renewable energy sources
- To plan equipment replacement schedules
Correct answer: To document and confirm that energy savings have been achieved as promised
An M&V plan provides a standardized method to quantify and verify actual energy savings against baseline to ensure contractual obligations are met.
Question 5: Which discount rate concept adjusts future energy savings to reflect their value in today's dollars?
- Inflation rate
- Utility escalation rate
- Net present value discount rate (Correct answer)
- Simple interest rate
Correct answer: Net present value discount rate
The discount rate in NPV analysis accounts for the time value of money, converting future cash flows into present-day equivalent values.
Question 6: What does an Energy Performance Contract (EPC) guarantee?
- Fixed utility rates for a defined period
- A minimum level of energy savings over the contract term (Correct answer)
- Unlimited equipment upgrades at no charge
- Government subsidies for renewable energy
Correct answer: A minimum level of energy savings over the contract term
In an EPC, an Energy Service Company (ESCO) guarantees a defined level of energy savings, assuming financial risk if savings targets are not met.
