What the Distributed Generation Certified Professional Credential Is
The Distributed Generation Certified Professional credential is a professional certification for people who evaluate, plan, permit, finance and manage distributed generation and combined heat and power (CHP) projects. Distributed generation refers to power produced at or near the point of use rather than at a distant central station, and CHP refers to systems that capture useful thermal energy alongside electricity. The certification tests whether a practitioner can reason about both the technology and the business and regulatory environment surrounding it.
If you have seen the acronym elsewhere, note that several unrelated credentials share the same letters. This page, and this entire site, concerns only the AEE Distributed Generation Certified Professional. For quick-reference explanations of the name itself, see What Does DGCP Stand For? and DGCP Meaning. For a broader overview of the credential, see DGCP Certification.
Who Issues It and How It Is Administered
The Association of Energy Engineers (AEE) issues and administers the certification. AEE offers testing in person and through ProctorU remote delivery, so candidates can choose a format that fits their location and schedule. Testing rules, including what you may bring into the exam, are published in AEE's certification FAQs and remote proctoring pages, and you should read them before booking rather than relying on memory or secondhand summaries.
Because AEE controls eligibility review, training approval and exam delivery, the process has several distinct gates. Understanding the sequence early prevents the most common planning mistake: assuming you can simply register and sit for the test. For scheduling considerations, see DGCP Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Eligibility Routes and the Training Requirement
AEE publishes several routes to eligibility, which combine education and experience in different ways. Candidates qualify through one of the following:
| Route | Education / Status | Experience Required |
|---|---|---|
| Route 1 | Related four-year degree, or PE or RA licensure | Three years of relevant experience (for the PE or RA path) |
| Route 2 | Unrelated four-year degree or two-year associate degree | Five years |
| Route 3 | No degree | Ten years |
| Route 4 | Current CEM (Certified Energy Manager) status | Per AEE's published requirements |
Beyond these routes, two further requirements apply: completion of approved training and certification-board approval of your application. Approved training is a separate requirement and is not bundled into the exam fee. There is also a DGCP-IT designation, which gives candidates six years to meet full eligibility after completing the required training, submitting an application and passing the DGCP examination. Always confirm current details on AEE's official page for becoming a DGCP.
How the Exam Is Built: Format, Scoring and Rules
The AEE study guide specifies an 85-question examination delivered over four hours. The exam is open book, which changes how you should prepare. It is not a memorization test, and it rewards organization, familiarity with your references and the ability to find and apply information quickly.
Item Types and Point Values
| Item Type | Number of Items | Points Each |
|---|---|---|
| Qualitative questions | 60 | 10 |
| Short calculations | 20 | 15 |
| Longer calculations | 5 | 20 |
Passing requires 700 of 1,000 points, which is 70%. AEE describes its examinations as multiple choice, while the DGCP sample questions include true/false selections and numerical calculations, so expect some variety in how items are presented. For a deeper look at the threshold, read DGCP Passing Score 2026: Exactly What You Need to Pass.
What You May and May Not Bring
- Permitted: printed references, bound notes and a hand calculator.
- Prohibited: internet-enabled or Bluetooth-enabled calculators and electronic reference materials.
The Three Published Question Categories
AEE's Body of Knowledge publishes three question categories with percentage ranges. These are official exam question-category headings, not topical study chapters, so they describe the kind of question you will see rather than the subject matter covered.
Domain 1: Qualitative Questions (69-71%)
This is the largest category by a wide margin. It covers conceptual and descriptive items across distributed generation and CHP. Sixty of the 85 items are qualitative, each worth 10 points.
- Technology characteristics and applications
- Regulatory, permitting and project management concepts
- Economic reasoning expressed in words rather than numbers
Domain 2: Short Calculation Questions (22-24%)
Twenty items worth 15 points each. These require compact numerical work, typically a single calculation chain, using a hand calculator.
- Energy and thermal relationships
- Efficiency and performance measures
- Basic economic calculations
Domain 3: Longer Calculation Questions (1-2%)
Five items worth 20 points each, requiring multi-step numerical work.
- Extended problems that combine several concepts
- Careful unit handling and documentation of steps
What Candidates Actually Need to Master
AEE's study guide organizes preparation into ten headings. These are unweighted curriculum headings, and the guide itself states that it does not cover every exam question, so use them as a foundation rather than a guarantee of coverage.
- Introduction to Distributed Generation and CHP
- Distributed Generation and CHP Technologies
- Energy and Thermal Basics of Distributed Generation and CHP Technologies
- Power Cycle Performance Measures for Distributed Generation and CHP Technologies
- Economic and Life Cycle Cost Analysis for Distributed Generation and CHP Systems
- PURPA and FERC Rules for QF's and SPP's
- Summary Data on Distributed Generation and CHP Technologies and A Case Study
- Regulatory and Permitting Systems Issues For Distributed Generation and CHP Systems
- Distributed Generation and CHP Project Management
- Distributed Generation and CHP System Case Studies
Where Technical Depth Pays Off
Headings three and four, thermal basics and power cycle performance measures, are the natural source of calculation items. Candidates should be comfortable moving between electrical and thermal energy, interpreting efficiency measures for systems that produce both, and working through the arithmetic with a hand calculator under time pressure.
Where Policy and Economics Matter
Heading five covers economic and life cycle cost analysis, which connects directly to project decision-making. Heading six, on PURPA and FERC rules for qualifying facilities and small power producers, introduces regulatory vocabulary that appears in qualitative items. Note that the guides include historical regulatory references, so pair the study guide with an awareness that regulations evolve. Headings eight and nine address permitting and project management, which reflect the practical realities of getting a system built and operating.
Key Takeaway
Because qualitative questions dominate the published ranges, breadth across all ten curriculum headings is worth more than perfecting any single calculation type. Build breadth first, then sharpen calculations.

Fees, Retests and Renewal Mechanics
| Item | Amount / Rule |
|---|---|
| U.S. application and examination fee | USD 400 |
| Retest | USD 200 |
| Approved training | Required; paid separately |
| Renewal cycle | Every three years |
| Renewal credits | Ten AEE renewal credits |
| Renewal fee | USD 300 |
| CEU conversion | One conventional CEU equals two AEE renewal credits |
The exam fee is only one part of the total investment, since training is a separate and mandatory cost. Planning your budget around the full path, rather than just the fee line, avoids surprises. A complete breakdown is available in DGCP Certification Cost 2026: Complete Pricing Breakdown. If you plan to pursue approved training, our DGCP Training page is a useful starting point.
Who Pursues the Credential and Where It Fits
The certification appeals to professionals whose work touches the planning, financing, regulation or delivery of on-site power and CHP projects. Typical backgrounds include energy engineers, facility and utility managers, consultants, project developers, and engineers or architects expanding into energy systems. The eligibility routes, which include PE and RA licensure, a CEM credential and long experience without a degree, signal that AEE expects a mix of technical and practical backgrounds.
Employers in this space tend to be energy service companies, consulting and engineering firms, project developers, and organizations that own large facilities with heat and power needs. We do not quote salary figures here because no verified issuer data supports specific numbers.

Sequencing Your Preparation Around the Scoring Math
The scoring structure suggests an order of attack. Sixty qualitative items at 10 points each total 600 points, twenty short calculations at 15 points each total 300 points, and five longer calculations at 20 points each total 100 points. That is 1,000 points, with 700 needed to pass. A candidate strong on concepts can bank a large share of the passing score before touching the calculations, while a candidate who skips qualitative breadth faces a steep climb.
Concepts and Technology
- Work through the study guide headings on DG and CHP technologies and fundamentals
- Begin building tabbed, bound reference material for open-book use
Calculations
- Practice thermal, power cycle and performance measure problems with a hand calculator
- Drill the short calculation format until setup becomes automatic
Economics, Regulation and Projects
- Cover life cycle cost analysis, PURPA and FERC rules, permitting and project management
- Review the case studies for applied reasoning
Timed Practice
- Take full-length timed sets and refine your reference index
- Use the DGCP practice tests to find weak areas
This timeline is a sample, not a requirement, so adjust it to your background and the length of your approved training. Engineers comfortable with thermodynamics may compress the calculation weeks, while those from a policy or finance background may need more time there.
Key Takeaway
Because the exam is open book, your reference index is part of your preparation. Spend time organizing and tabbing materials so you can locate answers quickly, and rehearse with timed questions from the main practice test site.
