Exelon Internship 2027–2028: Programs, Deadlines & How to Apply

Last updated: August 2026

Exelon's summer-2027 internship applications are not live yet, and Exelon's own board proves it: on August 15, 2026 the company carried 114 open requisitions and zero of them were internships – there isn't even an Intern/Co-Op category in the job board's own facet list. Based on the documented pattern (last year's wave opened September 5–8, 2025), that changes in roughly three to six weeks. You apply during 2026, you intern in summer 2027, a paid 10-week placement across six regulated utilities – ComEd, PECO, BGE, Pepco, Delmarva Power and Atlantic City Electric – serving almost 11 million customers and backed by a $41.3 billion four-year capital plan. One warning worth taking seriously: Exelon moved its 2026-cycle deadline about 10 to 12 weeks earlier than the year before, from late February to mid-December. Plan off last year's date and you could miss the whole window.

Quick Facts

The two things that matter most: applications aren't open yet but should be within weeks, and Exelon moved last year's deadline 10 to 12 weeks earlier than the year before – don't plan off last year's date.

Externships are short, remote professional experience programs where you finish a real project with a real company. The Hydroficient IoT Cyber Defense Externship and the Beats by Dre Data Analytics Externship build exactly the documented, deadline-bound project evidence Exelon's own requisitions reward, even though Exelon names no specific tool by name.

What Is an Exelon Internship?

An Exelon internship is a paid, 10-week summer placement (June to August) across Exelon's six regulated transmission-and-distribution utilities – ComEd, PECO, BGE, Pepco, Delmarva Power and Atlantic City Electric – serving almost 11 million customers as a Fortune 200 company (Nasdaq: EXC). Roughly 400 interns join each summer, per Vault, placed into engineering, IT, data science, finance, cyber security and other function groups, then assigned to a utility rather than choosing one upfront. Exelon's own internship page cites a Vault Best Energy Internship recognition, though that badge dates to 2018–2021 and hasn't been refreshed since. A more current signal: on Glassdoor, Intern is the single most-reviewed job title at Exelon, and it's among the highest-rated. Note that Exelon is not the same company as Constellation Energy, which took the nuclear generation fleet when the two separated in 2022.

When Do Exelon Internship Applications Open for 2027–2028?

Exelon's own requisitions give a documented pattern to project from, but it moved fast between cycles: the summer-2026 wave opened September 5–8, 2025 and closed on a spread from November 30 to December 19, 2025, while the summer-2025 wave had run until late February. That's the window pulling in roughly 10 to 12 weeks year over year. Function groups don't all close together, either – Data Science/Analytics shut nearly three weeks before Communications, Cyber Security and Business/HR/Marketing in the 2026 cycle. Project the same shape forward and summer-2027 applications should open around early-to-mid September 2026 and run about 14 weeks, but treat that window as directional, not fixed, given how much it already moved once.

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

Exelon publishes a real cutoff on every requisition, not a rolling window. A "this posting may close before the stated date" line does show up on some mirror sites, but it's traceable to the mirror's own page template – it's absent from every non-mirror copy of the same requisitions and from all of the 2025-cycle listings, which means it isn't Exelon's language at all. The bigger risk is planning off last year's calendar. Applications for summer 2026 closed between November 30 and December 19, 2025 – roughly 10 to 12 weeks earlier than the equivalent summer-2025 deadlines in late February. A student who assumes "Exelon closes in the spring" because that's what happened the year before would miss the entire window. Apply the week your function group posts. Don't wait for a deadline reminder Exelon has never promised to send.

Which Exelon Internship Programs Should You Target?

Exelon doesn't run named branded tracks. It posts one requisition per function group each cycle, and which six of the nine you'll actually see depends on the year. Here are the most consistently posted:

See all nine function groups on Exelon's internship page. Corporate functions like these post one umbrella requisition across all six utilities; engineering is the exception, posted per region under the operating utility's own name, so a Philadelphia applicant is applying to a PECO-branded requisition, not a generic Exelon one.

What Are the Eligibility Requirements?

Exelon publishes the same core requirements on every 2026-cycle intern requisition read:

• Enrollment: currently enrolled in a Bachelor's, Master's or post-secondary program, or an Associate's program with acceptance into a Bachelor's already secured. Actively taking classes.

• GPA: a flat 2.8 cumulative and 3.0 in your major, stated with no "preferred" softening – unusually low for the industry, but the major number is the one that actually binds.

• Track record: "a track record of outstanding academic performance," alongside stated leadership, communication and comfort working analytically under ambiguity.

• Work authorization: Exelon's own requisition text states no sponsorship condition either way; a third-party structured field on mirror sites lists eligible work rights as US Citizen, US Permanent Resident, or US Student Visa – confirm current sponsorship policy directly on the live requisition.

• Background clearance: every offer is contingent on a background investigation and drug screen before onboarding, per Exelon's own hiring-process page.

Is Exelon's GPA Requirement a Hard Cutoff?

Yes, and it's a two-part one most readers miss. Exelon states "Minimum GPA: Cumulative 2.8 / Major 3.0" as a flat rule on every 2026-cycle requisition, with none of the "generally preferred" softening common elsewhere in this series. The cumulative 2.8 floor is genuinely low for the industry, but the 3.0 major GPA is the number that actually gates most applicants. One real exception worth knowing: the engineering requisitions read list only the 2.8 cumulative floor, with no separate major-GPA line at all.

What Skills Does Exelon Look For, and How Do You Build Them?

Read all 16 of Exelon's recent intern requisitions and you'll find something unusual: the Primary Duties, Job Scope and Preferred Qualifications sections are blank on every single one, verified across four independent job-board mirrors. Exelon doesn't screen interns on a tool list, because it doesn't publish one – it screens on GPA, class standing and five soft-skill lines that appear on all 16 requisitions: communication, leadership, interpersonal skills, working independently under a supervisor, and outstanding academic performance. Read that as an opportunity, not a gap: with no technical checklist to reverse-engineer, documented independent project work carries more relative weight here than at a company that names Python or AutoCAD outright.

Build These Skills Before You Apply

Since Exelon's own JDs name no technical tool, treat each Externship below as building adjacent, documented project evidence for the specific function group it's tied to.

Exelon has no power-systems or utilities-specific Externship in the active catalog, and this page doesn't imply one. Each row above builds the closest documented, deadline-bound project evidence for the function Exelon actually screens on – academics and soft skills, not a named tool.

What Is the Exelon Application and Interview Process Like?

Exelon publishes its own seven-step hiring process (labeled general, not intern-specific):

1. Apply through Exelon's Intern/Co-Op board once it posts, or join the talent network now for the alert. Pick a function group, not a utility – placement happens after you apply.

2. Screening. "Candidates complete an initial screen via phone or recorded video," per Exelon's own hiring-process page.

3. Pre-employment testing (some roles). Some Operating Company positions require an Edison Electric Institute (EEI) aptitude test, not a coding assessment. Exelon publishes free EEI practice tests to prep with.

4. Panel interview. "The most qualified candidates will be interviewed by a panel of interviewers," per Exelon's process page.

5. Contingent offer, then a background investigation and drug screen before a start date is confirmed.

The highest-impact move isn't on the job board at all. Reddit and Glassdoor both describe Exelon interviewing students on the spot at campus career fairs, sometimes with an offer the same day. Bring STAR-format stories and go.

What Students on Reddit Say

Three threads show what the process actually looks like.

How Do You Stand Out for One of Exelon's ~400 Intern Seats?

Four moves, all doable before the board opens. First, go to your campus career fair with STAR stories ready – Reddit and Glassdoor both describe Exelon interviewing, and sometimes offering, students on the spot there, which is unusual in this page set. Second, know your function and know which utility it maps to: corporate functions like data science or finance post one requisition across all six utilities, but engineering posts per utility under the operating company's own name, so a Philadelphia engineering applicant is applying to PECO, not a generic Exelon listing – naming the right entity is free signal. Third, watch the calendar instead of trusting last year's date: Exelon's deadline moved 10 to 12 weeks earlier between the 2025 and 2026 cycles, and different function groups close on different dates within the same cycle. Fourth, check your major GPA specifically – Exelon's stated floor is cumulative 2.8 and major 3.0, and the major number is the one that actually binds. Vault puts Exelon's class at roughly 400 interns each summer, though that figure may predate Exelon's 2022 separation from Constellation Energy. Exelon publishes no applicant count or acceptance rate, so treat the internship as a genuine evaluation rather than a numbers game.

FAQ

Can I still apply for a summer 2026 Exelon internship?

No. Exelon's summer-2026 intern requisitions closed between November 30 and December 19, 2025, and that class ran June to August 2026. As of August 2026, Exelon's Intern/Co-Op job category returns zero results. The next open cycle is summer 2027, expected to post around September 2026.

When do Exelon internship applications open for summer 2027?

Expected around early-to-mid September 2026, roughly nine months before a June 2027 start. That projects the documented 2026 cycle, which posted September 5 to 8, 2025. Exelon has not published summer-2027 dates, so join its talent network for alerts.

Are Exelon internships rolling?

No. Exelon publishes a hard closing date on each requisition, and the 2026 cycle stayed open about 14 weeks. Function groups close on different dates, though: data science closed November 30, 2025 while cyber, communications and business closed December 19. Apply as soon as your function posts.

What GPA does Exelon require for an internship?

A cumulative GPA of 2.8 and a major GPA of 3.0, stated flatly in every Exelon intern requisition with no "preferred" softener. The major number is the one that binds. Engineering requisitions are looser, listing only the 2.8 cumulative floor with no major requirement.

How much do Exelon interns get paid?

Exelon's own project management internship requisition listed $20.00 to $31.50 an hour, and an engineering requisition listed $20 to $32. Community reports on levels.fyi cluster at $21 to $24.50, rising with class year. Exelon adds a $200-per-week housing stipend if you relocate more than 50 miles.

Is an Exelon internship at ComEd, PECO, BGE or Pepco?

It can be any of them. Exelon is a holding company for six regulated utilities, and most intern requisitions are posted once across "Various Exelon Locations," so you apply to a function and are placed at a utility. Engineering is the exception, posted per region under the utility's own name.

What is the Exelon intern interview process like?

Exelon publishes a seven-step process: apply, screening by phone or recorded video, pre-employment testing, a panel interview, a contingent offer, then a background investigation and drug screen. Students on Reddit and Glassdoor also report on-the-spot STAR-format interviews at campus career fairs, so prepare those stories.

Is Exelon the same company as Constellation?

No, not since February 2022, when Exelon separated Constellation Energy. Constellation took the competitive generation business, including the nuclear fleet. Exelon today is six fully regulated transmission and distribution utilities. If you want a nuclear internship, that's Constellation, and it's a separate application.

The window is about to open, and last cycle it shut 10 to 12 weeks earlier than the year before. Spend the runway building proof: a remote Externship turns "interested in the grid" into a finished project a September application can point to.
