We are a collaborative, competitive, innovative, and energetic group of engineers and team leaders who incorporate a holistic approach towards consulting engineering, performance contracting, and zero energy projects. We focus on finding engineers whose personalities lead them to excellence, and we provide exceptional opportunities for our employees.
The core business of our Energy Solutions division is the delivery of Guaranteed Energy Savings Performance Contracts (ESPCs). Simply put, our ESPCs are a viable way to upgrade and renovate facilities in a budget-neutral or even budget-positive way. The process diverts money already being spent on utilities and directs it into facility upgrades, covering scope development, design, bidding, construction management, commissioning, measurement and verification, and even ongoing energy management services. We have experience in designing the nation’s most energy efficient buildings, including many zero energy buildings. Our knowledge is unparalleled in the Guaranteed ESPC market, which allows us to dive deeper than our competitors. CMTA Energy Solutions has a robust co-op program for college students pursuing a degree in engineering. We offer an immersive experience in the world of Guaranteed Energy Savings Performance Contracting for one or more semesters. Our co-ops build competitive industry skills in a hands-on environment through collaborative project tasks with full-time engineers while under the direct supervision of Professional Engineers. Our program is designed to develop students into full-time caliber employees that contribute to the company’s growth. The ideal candidate will possess excellent interpersonal skills and will be able to work well both as a team member and independently. Our program stands apart from the typical, rehearsed co-op rotation in which every co-op gains the same experience because it is designed for co-ops to stand out and take on challenging projects. Co-ops will be involved with multiple Guaranteed Energy Savings Performance Contracts and will have a role in every stage of their development. Each stage offers a variety of valuable experiences, from initial development through implementation. Whether co-ops are interested in building their skill set in identifying and calculating energy savings measures, developing renovation documents, or hands-on field experience, CMTA Energy Solutions is bound to overcome expectations. Lighting Co-ops can expect to get hands on experience with commercial lighting systems.

Tips for Your Energy Internship Search
Apply earlier than the energy recruiting calendar suggests
Large utilities, oil and gas majors, and renewable energy companies close summer intern cohorts by October or November the year before. Smaller firms and co-op programs post closer to start dates. Check listings in early fall and set alerts so you don't miss the earliest deadlines for the most competitive programs.
Build project evidence before you need it
Energy intern hiring teams want something concrete to assess, not just a course list. Document two or three projects with clear methodology and visible outputs: a renewable-systems model, a load-flow analysis, a CAD design, or an energy-data script. Link to repositories or reports so recruiters can review your work directly rather than taking your word for it.
Work your campus network and apply directly at the same time
Campus career fairs surface structured programs tied to your university, and professors or career center staff often know which energy employers recruit from your school before roles post publicly. Applying directly to smaller companies running their own cohorts alongside campus activity widens the pool you reach and catches openings that never appear at university events.
Practice the actual energy intern interview format out loud
Engineering intern screens typically involve technical questions on power systems, thermodynamics, or circuit analysis. Data and modeling roles often include an analytics or Python exercise. Practice out loud and walk through your reasoning step by step, since interviewers in energy weigh how you approach a problem as much as whether you reach the right answer.
Target structured rotational programs at larger energy companies
Major utilities and integrated energy companies run cohort-based rotational internships designed to move you across generation, grid operations, and renewables development in a single term. These programs are built to train people new to the field, recruit in the early fall, and fill their first wave fast. Identify the ones that match your interest and get your applications in before general recruiting opens.
Set your work-type filter before you start
On-site roles are 93% of the energy internships listed here. Decide what you can commit to before you search, whether that's on-site at a plant or substation, hybrid, or fully remote for modeling and analysis work, and filter by location and work type from the start so you spend your time on roles you can actually take.
Energy Internships: Frequently Asked Questions
How do I get an energy internship?
Lead with coursework, technical projects, and a portfolio rather than work history, hiring teams expect limited experience at the intern level and want something concrete to assess. For energy candidates, that means documented project work: a load-flow analysis, a renewable-systems model, or a CAD design with clear methodology. Combine direct applications with campus career fairs, where recruiters often move faster for students they meet in person.
Can an energy internship turn into a full-time job?
Many employers extend return offers to strong interns, but conversion is never guaranteed. What actually drives it in energy is consistent performance on real project deliverables, available headcount on the team, and how early in your internship you signal interest. Position for one by treating every assignment as a work sample, without assuming the offer will follow automatically.
When should I apply for energy internships?
Earlier than most expect. Large utilities, oil and gas companies, and renewable energy firms recruit summer interns the preceding fall, often closing cohorts by November or December. Smaller companies, engineering consultancies, and co-op programs post closer to their start dates, so openings appear year-round. Checking listings regularly rather than waiting for a single recruiting season keeps you from missing early deadlines.
Are energy internships paid?
Most professional energy internships in the United States are paid. Compensation varies by company size, industry segment, and location, a large utility or an oil and gas major typically pays more than a small nonprofit or municipal agency. Where employers disclose compensation, it appears directly in the listing, so you can factor it into your decision before applying.
What should an energy internship resume include?
Lead with projects, not work history. Highlight two or three complete, documented projects that show what you built or analyzed, which tools you used, and where a recruiter can see the output, linked code repositories, published reports, CAD or design portfolios, or modeled energy systems. Add relevant coursework in power systems, thermodynamics, or environmental science, and keep the whole document to one page.
Are there remote energy internships?
Yes. Remote and hybrid roles make up 7% of the energy internship listings here, with the rest on-site. Remote cohorts in data analysis, energy modeling, and policy research fill fast, so apply early and use the work-type filter to see them without sorting through on-site postings that don't fit your situation.
What is a rotational energy internship?
Rotational internships place you across two or more business units, generation, transmission, renewables development, or grid operations, over one internship term, giving you broader exposure than a single-team placement. Larger utilities and integrated energy companies run structured versions of these programs specifically for students new to the field. They recruit early and fill quickly, so apply in the first wave of openings.
Can international students get energy internships?
Yes. F-1 students can intern through CPT while enrolled or through OPT work authorization after finishing a degree, and the employer does not have to file anything for either, so many companies are open to international interns. Confirm your eligibility and timing with your university's international student office before accepting an offer.
