Three rounds, honest feedback on every answer. Free, no sign-up.Last updated: October 2026
Duke Energy places 250+ interns every summer across engineering, IT, finance, and environmental science, and more than 900 of its current employees started their careers as Duke Energy interns. For the 2027–2028 cycle (you apply during 2026, you intern in summer 2027), some summer 2027 postings are still open on Duke Energy's Workday portal: Information Technology and Telecommunications internships for summer 2027 posted on August 31, 2026, and the Engineering Internship & Co-op Program, UX Design and other summer 2027 roles followed on October 2. Each posting prints its own apply-by date, and they are close: on October 21, 2026 the IT, Telecommunications, UX Design, Aviation, Local IT Support and Ohio Construction Management postings had closed, the Engineering Internship & Co-op Program was still listed after the October 16 date it prints, and the latest undergraduate summer 2027 date was October 30 (Waste & Groundwater Engineering and Nuclear Cybersecurity, both posted October 21). That is far earlier than last cycle's January to February engineering deadline, so if your track is still listed, apply now. The average time from application to hire is 54 days, so missing a deadline means waiting a full year.

what's a Duke Energy Internship?
A Duke Energy internship is a paid, 10–12 week summer placement that embeds college students into real roles at one of the largest utilities in the US. Duke Energy is the highest-ranking utility on the Fortune 500 (No. 144) and has been named to Fortune's World's Most Admired Companies list nine years running. The company serves nearly 9 million electric customers across the Carolinas, Midwest, and Florida. Interns receive the same benefits as full-time employees, and managers assign real deliverables rather than busywork.
When Do Duke Energy Internship Applications Open for 2027–2028?
Duke Energy's internship calendar is staggered by function rather than a single window. Based on the Summer 2026 cycle, postings go live in September–October, returning-intern deadlines fall in December, new engineering deadlines in January–February, and IT, supply chain, and EH&S deadlines stretch into March–April. For summer 2027 the calendar moved earlier: IT and Telecommunications posted on August 31, 2026, Engineering and UX Design on October 2, and the postings' apply-by dates ran from October 11 (UX Design) to October 19, 2026 (Construction Management in Ohio), with the Engineering Internship & Co-op Program printing 11:59 PM on October 16. Later postings run to October 29 (Substation / Line Tech) and October 30 (Waste & Groundwater Engineering and Nuclear Cybersecurity, posted October 21). If your track is still listed, apply now and start in May 2027.
On October 21, 2026, summer 2027 postings for Substation / Line Tech (apply by October 29), Waste & Groundwater Programs Engineering and Nuclear Cybersecurity (both by October 30) and the MBA Internship (by November 13) were accepting applications on the Workday portal. The Engineering Internship & Co-op Program was still listed after the October 16 date it prints, so engineering applicants should submit now. Aviation, Local IT Support, Construction Management, IT, Telecommunications and UX Design had closed.
Summer 2027 postings went live on the Workday portal: IT and Telecommunications on August 31, Engineering Internship & Co-op Program and UX Design on October 2. Returning-intern postings run separately and are for past interns only.
Workday end dates on the summer 2027 postings: UX Design October 12, IT in Hartsville, SC October 13, IT in Charlotte and Telecommunications October 14, Aviation October 17, Local IT Support October 19, Construction Management in Ohio October 20 (all passed, postings no longer listed), Substation / Line Tech in the Carolinas October 30, Waste & Groundwater Engineering and Nuclear Cybersecurity October 31. Most postings print an apply-by time of 11:59 PM on the day before the end date. The engineering program prints October 16 but was still listed on October 21. Last cycle engineering stayed open until February 27, 2026, so this year's window is much shorter. Duke may repost some tracks later, but do not count on it.
Interviews (phone screen plus panel) and offers. Last cycle interviews ran February through April and offers March through May; with this year's earlier postings, expect both to come sooner. Average time-to-hire: 54 days.
10–12 weeks, May through August. 250+ interns across engineering, IT, finance, environmental science, and supply chain. Capstone presentations close the program. Do the job well: 900+ current employees started right here.
How to read this page: our dates come from tracking previous recruiting cycles and daily posting data. Treat them as informed estimates based on historical patterns, not confirmed dates. The company's official careers page is always the most current source. If a role is posted there, go by that, even if this page suggests the window hasn't opened yet.
Why You Must Apply the Week Applications Open
Duke Energy doesn't use rolling admissions, but that doesn't mean timing is irrelevant. Last cycle engineering postings closed in January to February; for summer 2027 the engineering posting prints an 11:59 PM, October 16, 2026 deadline and was still listed on October 21, and engineering is the largest share of the 250+ intern class. Applications are reviewed after the deadline, not as they arrive, and the Returning Intern/Co-op track runs separately for past interns only. If you're a first-time applicant, submit now: on October 21, 2026 the undergraduate summer 2027 apply-by dates still ahead were October 29 (Substation / Line Tech) and October 30 (Waste & Groundwater, Nuclear Cybersecurity), and the IT, Telecommunications, UX Design, Aviation, Local IT Support and Ohio Construction Management postings had already closed.
Which Duke Energy Internship Programs Should You Target?
Duke Energy runs eight distinct internship and co-op tracks. Engineering is the largest, but IT, supply chain, and environmental roles are growing as the company invests $103 billion in grid modernization and clean energy.
| Program | Focus | Duration | Key skills |
|---|---|---|---|
| Engineering Intern & Co-op | Transmission, distribution, nuclear, renewables, grid planning | 10–12 weeks | ABET-accredited engineering degree, safety awareness, technical fundamentals |
| IT Summer Internship | Software engineering, data analytics, AI, cybersecurity, cloud | 10–12 weeks | CS or IT major, Python, SQL, data analysis |
| Supply Chain Internship | Procurement, logistics, business analytics | 10–12 weeks | Business analytics, data science, supply chain or logistics coursework |
| Environmental Health & Safety | Environmental compliance, safety management | 10–12 weeks | Environmental science, biology, chemistry, geology |
| MBA Internship | Graduate-level business strategy and operations | 10–12 weeks | MBA enrollment, analytical problem solving, communication |
| STEM Sophomore Program | Foundation-funded pipeline for second-year STEM students | 10–12 weeks | STEM major, rising sophomore standing, IUPUI partnership |
Duke Energy also runs a Returning Engineering Intern/Co-op track with separate deadlines and a Power Careers Program scholarship pipeline in the Carolinas. The company partners with 19 HBCU institutions and has committed $300,000 to congressional internship programs for students of color.
What Are the Eligibility Requirements?
Duke Energy publishes clear eligibility criteria across its Workday postings:
• Enrollment: currently enrolled in a 4-year undergraduate program (rising sophomore, junior, or senior) or an approved graduate program. Some positions accept community college students with at least 12 completed credit hours.
• GPA: minimum cumulative GPA of 2.75 (required). A 3.0 or higher is preferred for most roles. Specialized tracks like Quantum Computing & Strategy may require 3.5+.
• Graduation: must not graduate prior to August of the internship year (e.g., August 2027 for summer 2027). The program feeds return offers and co-op extensions, not first jobs.
• Documents: current transcript and resume must be submitted with the application.
• Work authorization: the summer 2027 postings live on October 21, 2026 state that the role is not visa sponsored and requires the ability to work lawfully in the U.S. without employment-based immigration sponsorship.
Which Majors Does Duke Energy Hire From?
The range is wider than most students expect. Engineering tracks accept nuclear, mechanical, civil, chemical, electrical, computer, industrial & systems, environmental engineering, and construction management, with ABET-accredited programs preferred. IT accepts computer science, information technology, and cybersecurity. Environmental tracks pull from geology, biology, chemistry, and ecology. And the business side covers finance, marketing, supply chain, logistics, data science, and business analytics. The 2.75 GPA floor is notably lower than many Fortune 500 programs, and the broad major list means Duke Energy casts a wider net than its size would suggest.
What Skills Does Duke Energy Look For, and How Do You Build Them?
Six prior-cycle Duke Energy internship postings share a consistent pattern: safety and compliance awareness show up across every engineering and field track, communication and teamwork appear in nearly all, and data analysis surfaces in IT, supply chain, and business roles. The technical requirements stay track-specific, but the behavioral bar is utility-wide: Duke Energy runs critical infrastructure, so every intern is expected to think about safety, process, and collaboration from day one.

what's the Duke Energy Application and Interview Process Like?
Duke Energy's interview funnel typically runs 2–3 rounds, with an average of 54 days from application to offer:
1. Apply on the Workday portal with a resume and current transcript. Each function has its own posting and deadline, so apply to the specific track that matches your major.
2. Phone screen with a recruiter or hiring manager. About 30 minutes covering your background, interest in energy, and understanding of the role. Shortlisted candidates for some positions may also receive an online assessment (EEI-style tests for operations roles; behavioral for engineering and IT).
3. Panel interview with 2–4 interviewers, including hiring managers, team members, and HR. Rotational format: one person asks STAR-method behavioral questions while others observe. Expect questions like "describe a time you led a team" and "how did you handle conflicting working styles."
4. Offer decision communicated within 1–2 weeks of the final interview. Glassdoor rates difficulty at 3.1 out of 5 (medium), with 50% positive candidate experiences.
Some operations and field roles use EEI (Edison Electric Institute) assessments, but engineering and IT interns are more likely to proceed directly to interviews after resume screening. Rehearse the STAR behavioral rounds instead.
What Students on Reddit Say
Three threads show the Duke Energy intern experience from the inside.
Be ready to explain your projects in plain language. They might have non-engineers on the panel, so connecting coursework to real applications matters more than technical depth alone.
The internship paid $21 an hour, which was solid for a first placement. Good experience overall and it opened doors to more advanced roles at other companies later.
It was a good experience and provided skills that led to more advanced internships later. Managers treated us like regular team members with real work, not make-work.
How Do You Stand Out When 250+ Seats Fill Across 8 Tracks?
Three moves, starting now while some postings are still live. First, know your track: Duke Energy's staggered deadlines mean each function has its own posting, and applying to the right one with a matching major and project portfolio beats scattershot applications. Second, show safety and process thinking in your interview answers, because this is critical infrastructure and every STAR story should reflect awareness of it. Third, arrive with finished analytical or technical work that speaks the JD's language. A cybersecurity or data-analysis project answers "tell me about a time you solved a technical problem" with an artifact, not an anecdote. And remember, 900+ employees started as interns, which means the panel is evaluating you for the long term.
