According to Association of Energy Engineers, “All exams are multiple choice. The number of questions on the exam varies per program.”[3]
The CEP is a certification offered by the Association of Energy Engineers (AEE) for people who buy electricity and natural gas, or advise on how it is bought. The exam is multiple choice and open book, with a time limit of 4 hours. AEE says the number of questions varies per program, so check your registration materials for your exam.
You can schedule the exam as part of an in-person training program or as a remote proctored exam. The dates listed on the AEE page include an exam on June 9, 2027 in Providence, RI and an exam on September 22, 2027 in Atlanta, GA.
The application and exam fee is $400. Retests cost $200 each. There is no limit on retakes, but you must earn a passing score within 3 years of completing the training course. After the exam, AEE sends an official score letter by email within 30 days.
A certification is in effect for 3 years. Renewal costs $300 every 3 years. This page does not list a passing score or eligibility requirements. Confirm both, and any changes to fees or dates, on the official AEE certification pages before you register.

Prepare for the CEP - Certified Energy Procurement Professional exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: In the context of grid reliability, what does 'N-1 contingency' mean?
Answer: A. The grid must remain stable after the loss of any single transmission or generation element
Explanation:
The correct answer is that the grid must remain stable after the loss of any individual transmission or generation element. N-1 is a planning and operating standard: operators study what happens if a line, transformer or generating unit suddenly drops out, and they keep enough margin that the system stays stable.
The renewable-to-fossil pairing is wrong because reliability standards do not match unit types. The net load option is wrong because it describes a demand condition, not a response to an equipment loss. The RTO option is wrong because N-1 has nothing to do with how many market operators exist.
Rule to remember: when a reliability term includes a minus sign and a number, it describes how many components can fail while the system stays secure.
Question: How frequently should ongoing assessments be conducted in Certified Energy Procurement Professional practice?
Answer: B. At regular intervals and as conditions change
Explanation:
The correct answer is at regular intervals and as conditions change. Good practice combines a routine schedule with reassessment whenever something material shifts, such as a new rate, a new contract or a change in operations.
Only when problems are reported is wrong because it is reactive, so issues are found late. Once annually regardless of circumstances is wrong because a fixed schedule ignores changes that happen between reviews. Only when required by external auditors is wrong because it treats assessment as a compliance chore instead of a management tool.
Rule to remember: monitoring works best when it is both scheduled and event-driven. Be wary of answers that use absolute words such as only or regardless.
Question: What distinguishes a Certified Environmental, Social, and Governance Planner certified professional from a non-certified practitioner?
Answer: B. Certification validates competency through standardized assessment against benchmarks
Explanation:
The correct answer is that certification validates competency through standardized assessment against benchmarks. The value of a credential is that everyone is measured the same way, so a client or employer has an objective signal.
Certified professionals always have more experience is wrong because certification does not mean a longer career, and the word always makes the claim too strong. There is no meaningful difference is wrong because the standardized assessment is exactly the difference. Certified professionals only work in larger organizations is wrong because certification is not tied to employer size.
Rule to remember: on credential questions, choose the answer about verified competency, and reject answers built on always, only or no difference.
Start with the official material. Read the AEE body of knowledge and list the content areas. Then take the practice set linked to each area from the table above and note which areas feel weakest.
Our questions are written by us with AI tools and are not real exam questions. Treat them as practice for the concepts, and confirm the format and number of questions for your program with AEE.
The certification application and exam fee is $400. If you need to retake the exam, a retest costs $200. Once certified, renewal is $300 every 3 years. Fees can change, so confirm the current amounts on the Association of Energy Engineers page before you register.
The CEP exam is multiple choice and open book, with a time limit of 4 hours. AEE says the number of questions varies per program, so this page does not give a fixed count. Check your registration materials for the details of your exam.
Yes. AEE sets no limit on the number of retakes, and each retest costs $200. The condition is that you must achieve a successful score within 3 years of completing the training course, so plan your retake dates with that window in mind.
You can schedule the exam as part of an in-person training program or take a remote proctored exam. The AEE page lists in-person dates including June 9, 2027 in Providence, RI and September 22, 2027 in Atlanta, GA. Check the AEE page for current dates.
AEE sends an official exam score letter by email, and the letters are sent within 30 days. If your letter has not arrived by then, contact AEE directly. This page does not state a passing score, so confirm that with the exam body.
A CEP certification is in effect for 3 years. Renewal costs $300 every 3 years. Check the AEE certification pages for the current renewal requirements, because this page only lists the fee and the length of validity.
